What is the topic of this review? This brief review discusses potential sex differences in arterial function across the age span, with special emphasis on the effects of oestrogen and testosterone on the vascular endothelium. What advances does it highlight? We discuss the relationship between the impacts of sex hormones on arterial function and health in the context of epidemiological evidence pertaining to the menopause and ageing. Studies performed in humans are emphasized, alongside insights from animal studies. Findings suggest that the combination of exercise and hormone administration should be potentially synergistic or additive in humans. This brief review presents historical evidence for the purported impacts of male and female sex hormones on the vasculature in humans, including effects on macro- and microvascular function and health. Impacts of ageing on hormonal changes and arterial function are considered in the context of the menopause. Physiological data are presented alongside clinical outcomes from large trials, in an attempt to rationalize disparate findings along the bench-to-bedside continuum. Finally, the theoretical likelihood that exercise and hormone treatment may induce synergistic and/or additive vascular adaptations is developed in the context of recent laboratory studies that have compared male and female responses to training. Differences between men and women in terms of the impact of age and cardiorespiratory fitness on endothelial function are addressed. Ultimately, this review highlights the paucity of high-quality and compelling evidence regarding the fundamental impact, in humans, of sex differences on arterial function and the moderating impacts of exercise on arterial function, adaptation and health at different ages in either sex. © 2015 The Authors.

Life cycle assessment (LCA) is a methodology that quantifies potential environmental impacts for comparative purposes in a decision-making context. While potential environmental impacts from pollutant emissions into water are characterized in LCA, impacts from water unavailability are not yet fully quantified. Water use can make the resource unavailable to other users by displacement or quality degradation. A reduction in water availability to human users can potentially affect human health. If financial resources are available, there can be adaptations that may, in turn, shift the environmental burdens to other life cycle stages and impact categories. This paper proposes a model to evaluate these potential impacts in an LCA context. It considers the water that is withdrawn and released, its quality and scarcity in order to evaluate the loss of functionality associated with water uses. Regionalized results are presented for impacts on human health for two modeling approaches regarding affected users, including or not domestic uses, and expressed in disability-adjusted life years (DALY). A consumption and quality based scarcity indicator is also proposed as a midpoint. An illustrative example is presented for the production of corrugated board with different effluents, demonstrating the importance of considering quality, process effluents and the difference between the modeling approaches.

Improving the health status of indigenous children is a long-standing challenge. Several United Nations committees have identified the health of indigenous peoples as a human rights concern. Addressing the health of indigenous children cannot be separated from their social, cultural, and historic contexts, and any related health program must offer culturally appropriate services and a community perspective broad enough to address the needs of children and the local worlds in which they live. Evaluations of programs must, therefore, address process as well as impacts. This paper assesses interventions addressing indigenous children's health in Brazil, ranging from those explicitly targeting indigenous children's health, such as the targeted immunization program for indigenous peoples, as well as more generalized programs, including a focus upon indigenous children, such as the Integrated Management of Childhood Illness. The paper discusses the tensions and complexities of ethnically targeted health interventions as well as the conceptual and methodological challenge of measuring the processes employed and their impact. The lessons learned, especially the need for countries to more systematically collect data and evaluate impacts using ethnicity as an analytical category, are drawn out with respect to ensuring human rights for all within health sector responses.

There are > 80,000 chemicals in commerce with few data available describing their impacts on human health. Biomonitoring surveys, such as the NHANES (National Health and Nutrition Examination Survey), offer one route to identifying possible relationships between environmental chemicals and health impacts, but sparse data and the complexity of traditional models make it difficult to leverage effectively. We describe a workflow to efficiently and comprehensively evaluate and prioritize chemical-health impact relationships from the NHANES biomonitoring survey studies. Using a frequent itemset mining (FIM) approach, we identified relationships between chemicals and health biomarkers and diseases. The FIM method identified 7,848 relationships between 219 chemicals and 93 health outcomes/biomarkers. Two case studies used to evaluate the FIM rankings demonstrate that the FIM approach is able to identify published relationships. Because the relationships are derived from the vast majority of the chemicals monitored by NHANES, the resulting list of associations is appropriate for evaluating results from targeted data mining or identifying novel candidate relationships for more detailed investigation. Because of the computational efficiency of the FIM method, all chemicals and health effects can be considered in a single analysis. The resulting list provides a comprehensive summary of the chemical/health co-occurrences from NHANES that are higher than expected by chance. This information enables ranking and prioritization on chemicals or health effects of interest for evaluation of published results and design of future studies. Bell SM, Edwards SW. 2015.

2016-11-10

To examine the evidence of the impact of patient- centered eHealth applications on patient care and to analyze if and how reported human factor issues mediated the outcomes. We searched PubMed (2014-2015) for studies evaluating the impact of patient-centered eHealth applications on patient care (behavior change, self-efficacy, and patient health-related outcomes). The Systems Engineering Initiative for Patient Safety (SEIPS 2.0) model was used as a guidance framework to identify the reported human factors possibly impacting the effectiveness of an eHealth intervention. Of the 348 potentially relevant papers, 10 papers were included for data analysis. None of the 10 papers reported a negative impact of the eHealth intervention. Seven papers involved a randomized controlled trial (RCT) study. Six of these RCTs reported a positive impact of the eHealth intervention on patient care. All 10 papers reported on human factor issues possibly mediating effects of patient-centered eHealth. Human factors involved patient characteristics, perceived social support, and (type of) interaction between patient and provider. While the amount of patient-centered eHealth interventions increases, many questions remain as to whether and to what extent human factors mediate their use and impact. Future research should adopt a formal theory-driven approach towards human factors when investigating those factors' influence on the effectiveness of these interventions. Insights could then be used to better tailor the content and design of eHealth solutions according to patient user profiles, so as to enhance eHealth interventions impact on patient behavior, self-efficacy, and health-related outcomes.

Evaluating external costs of human health and environmental impacts using IAEA model SIMPACTS

International Nuclear Information System (INIS)

Bobric, Elena; Jelev, Adrian

2005-01-01

SIMPACTS (Simplified Approach for Estimating Impacts and External Costs of Electricity Generation) model developed at the International Atomic Energy Agency is a powerful and convenient tool for evaluating external costs induced by different energy sources. The model was developed for industrial countries and for developing countries as well where studies of alternatives of sustainable energy policies are conducted. The SIMPACTS allow the decision making factors involved in energy policy to have reasonable estimates of environment impacts and relating costs appealing to a rather low number of input parameters. The paper aims at analyzing by means of SIMPACTS the environmental impact produced by Cernavoda NPP operation in two cases: a) the impact of the Cernavoda NPP itself; b) the impact of an hypothetical coal based power plant of the same power level and located on the Cernavoda NPP site. The SIMPACTS modules AIRPACTS and NUCPACTS were applied to assess the impacts on human health, agricultural crops and building materials from exposure to routine atmospheric emissions and as well to quantify and value the adverse effects on human health due to routine atmospheric release of radionuclides from the NPP, via radioactive waste ground disposal or resulting from accidents in nuclear facility, respectively. The conclusion of this study based on SIMPACTS model application to assess the health effects and damage cost per year is that the Cernavoda NPP presents the lower health effects and damage cost comparing with power plants of other types

High volume, hydraulic fracturing (HVHF) processes, used to extract natural gas and oil from underground shale deposits, pose many potential hazards to the environment and human health. HVHF can negatively affect the environment by contaminating soil, water, and air matrices with potential pollutants. Due to the relatively novel nature of the process, hazards to surface waters and human health are not well known. The purpose of this article is to link the impacts of HVHF operations on surface water integrity, with human health consequences. Surface water contamination risks include: increased structural failure rates of unconventional wells, issues with wastewater treatment, and accidental discharge of contaminated fluids. Human health risks associated with exposure to surface water contaminated with HVHF chemicals include increased cancer risk and turbidity of water, leading to increased pathogen survival time. Future research should focus on modeling contamination spread throughout the environment, and minimizing occupational exposure to harmful chemicals.

Influence of Human Factor Issues on Patient-Centered mHealth Apps' Impact; Where Do We Stand?

Wildenbos, G A; Peute, L W; Jaspers, M W M

2016-01-01

This paper discusses the preliminary results of a literature review on studies published in 2014-2015 concerning patient-centered mHealth applications' (apps) impact. Abstracts were included when they described a mHealth app targeted at patients and reported on the effects of this app on patient care. From a total of 559 potentially relevant articles, 17 papers were finally included. Nine studies reported a positive impact of the patient-centered mHealth app on patient care; 4 of these studies were randomized controlled trials. Measured impacts in the 17 studies focused on improving patients' physical activity, self-efficacy and medication adherence. Human factors issues potentially mediating these effects were discussed in all studies. Transitions in the interaction between healthcare providers and their patients were most often discussed as influencing the impact of the mHealth app. More research is needed, focussing on human issues mediating the effect of patient-centered mHealth apps to precipitate knowledge on the effectiveness of mHealth. This research should preferably be guided by socio-technical models.

Scholars spanning a variety of disciplines have studied the ways in which contact with natural environments may impact human well-being. We review the effects of such nature experience on human cognitive function and mental health, synthesizing work from environmental psychology, urban planning, the medical literature, and landscape aesthetics. We provide an overview of the prevailing explanatory theories of these effects, the ways in which exposure to nature has been considered, and the role that individuals' preferences for nature may play in the impact of the environment on psychological functioning. Drawing from the highly productive but disparate programs of research in this area, we conclude by proposing a system of categorization for different types of nature experience. We also outline key questions for future work, including further inquiry into which elements of the natural environment may have impacts on cognitive function and mental health; what the most effective type, duration, and frequency of contact may be; and what the possible neural mechanisms are that could be responsible for the documented effects. © 2012 New York Academy of Sciences.

Waste management programmatic environmental impact statement methodology for estimating human health risks

International Nuclear Information System (INIS)

Bergenback, B.; Blaylock, B.P.; Legg, J.L.

1995-05-01

The US Department of Energy (DOE) has produced large quantities of radioactive and hazardous waste during years of nuclear weapons production. As a result, a large number of sites across the DOE Complex have become chemically and/or radiologically contaminated. In 1990, the Secretary of Energy charged the DOE Office of Environmental Restoration and Waste management (EM) with the task of preparing a Programmatic Environmental Impact Statement (PEIS). The PEIS should identify and assess the potential environmental impacts of implementing several integrated Environmental Restoration (ER) and Waste Management (WM) alternatives. The determination and integration of appropriate remediation activities and sound waste management practices is vital for ensuring the diminution of adverse human health impacts during site cleanup and waste management programs. This report documents the PEIS risk assessment methodology used to evaluate human health risks posed by WM activities. The methodology presents a programmatic cradle to grave risk assessment for EM program activities. A unit dose approach is used to estimate risks posed by WM activities and is the subject of this document

Integrating human health into environmental impact assessment: case studies of Canada's Northern mining resource sector

Noble, B.F.; Bronson, J.E.

2005-01-01

This paper examines the integration of human health considerations into environmental impact assessment (EIA) in the Canadian North. Emphasis is placed on the northern mining sector, where more land has been staked in the past decade than in the previous 50 years combined. Using information from interviews with northern EIA and health practitioners and reviews of selected project documents, we examined three principal mining case studies, northern Saskatchewan uranium mining operations, the Ekati diamond project, and the Voisey's Bay mine/mill project, to determine whether and how health considerations in EIA have evolved and the current nature and scope of health integration. Results suggest that despite the recognized link between environment and health and the number of high-profile megaprojects in Canada's North, human health, particularly social health, has not been given adequate treatment in northern EIA. Health considerations in EIA have typically been limited to physical health impacts triggered directly by project-induced environmental change, while social and other health determinants have been either not considered at all, or limited to those aspects of health and well-being that the project proponent directly controlled, namely employment opportunities and worker health and safety. In recent years, we have been seeing improvements in the scope of health in EIA to reflect a broader range of health determinants, including traditional land use and culture. However, there is still a need to adopt impact mitigation and enhancement measures that are sensitive to northern society, to monitor and follow up actual health impacts after project approval, and to ensure that mitigation and enhancement measures are effective.

We compared water and sanitation system options for a coastal community across selected sustainability metrics, including environmental impact (i.e., life cycle eutrophication potential, energy consumption, and global warming potential), equivalent annual cost, and local human health impact. We computed normalized metric scores, which we used to discuss the options' strengths and weaknesses, and conducted sensitivity analysis of the scores to changes in variable and uncertain input parameters. The alternative systems, which combined centralized drinking water with sanitation services based on the concepts of energy and nutrient recovery as well as on-site water reuse, had reduced environmental and local human health impacts and costs than the conventional, centralized option. Of the selected sustainability metrics, the greatest advantages of the alternative community water systems (compared to the conventional system) were in terms of local human health impact and eutrophication potential, despite large, outstanding uncertainties. Of the alternative options, the systems with on-site water reuse and energy recovery technologies had the least local human health impact; however, the cost of these options was highly variable and the energy consumption was comparable to on-site alternatives without water reuse or energy recovery, due to on-site reuse treatment. Future work should aim to reduce the uncertainty in the energy recovery process and explore the health risks associated with less costly, on-site water treatment options.

Globally, modern mass transport systems whether by road, rail, water, or air generate airborne pollutants in both developing and developed nations. Air pollution is the primary human health concern originating from modern transportation, particularly in densely-populated urban areas. This review will specifically focus on the origin and the health impacts of carbonaceous traffic-related air pollutants (TRAP), including particulate matter (PM), volatile organic compounds (VOCs), and elemental carbon (EC). We conclude that the greatest current challenge regarding urban TRAP is understanding and evaluating the human health impacts well enough to set appropriate pollution control measures. Furthermore, we provide a detailed discussion regarding the effects of TRAP on local environments and pedestrian health in low and high traffic-density environments. Copyright © 2017 Elsevier Ltd.

Understanding the impacts of medical tourism on health human resources in Barbados: a prospective, qualitative study of stakeholder perceptions

Science.gov (United States)

2013-01-01

Background Medical tourism is a global health practice where patients travel internationally with the intention of receiving medical services. A range of low, middle, and high income countries are encouraging investment in the medical tourism sector, including countries in the Caribbean targeting patients in North America and Europe. While medical tourism has the potential to provide economic and employment opportunities in destination countries, there are concerns that it could encourage the movement of health workers from the public to private health sector. Methods We present findings from 19 semi-structured interviews with stakeholders across the public health care, private health care, government, allied business, and civil society sectors. These interviews were conducted in-person in Barbados and via phone. The interview transcripts were coded and a thematic analysis developed. Results Three themes were identified: 1) Stakeholder perceptions of the patterns and plans for health human resource usage by current and planned medical tourism facilities in Barbados. We found that while health human resource usage in the medical tourism sector has been limited, it is likely to grow in the future; 2) Anticipated positive impacts of medical tourism on health human resources and access to care in the public system. These benefits included improved quality control, training opportunities, and health worker retention; and 3) Anticipated negative impacts of medical tourism on health human resources and access to care in the public system. These impacts included longer wait times for care and a shift in planning priorities driven by the medical tourism sector. Conclusions Stakeholders interviewed who were connected to medical tourism expansion or the tourism sector took a generally positive view of the likely impacts of medical tourism on health human resources in Barbados. However, stakeholders associated with the public health system and health equity expressed concern

To collate and synthesize current knowledge of components of urban agriculture (UA) with a thematic emphasis on human health impact and a geographic emphasis on East Africa. Data management followed a structured approach in which key issues were first identified and then studies selected through literature search and personal communication. Evidence-based principles. Urban agriculture is an important source of food security for urban dwellers in East Africa. Descriptors of UA are location, areas, activities, scale, products, destinations, stakeholders and motivation. Many zoonotic and food-borne diseases have been associated with UA but evidence on human health impact and management is lacking. Major constraints to UA are illegality and lack of access to input and market; policy options have been developed for overcoming these. Urban agriculture is an important activity and likely to remain so. Both positive and negative human health impacts are potentially important but more research is needed to understand these and set appropriate policy and support levels.

Floods are the most common hazard to cause disasters and have led to extensive morbidity and mortality throughout the world. The impact of floods on the human community is related directly to the location and topography of the area, as well as human demographics and characteristics of the built environment. The aim of this study is to identify the health impacts of disasters and the underlying causes of health impacts associated with floods. A conceptual framework is developed that may assist with the development of a rational and comprehensive approach to prevention, mitigation, and management. This study involved an extensive literature review that located >500 references, which were analyzed to identify common themes, findings, and expert views. The findings then were distilled into common themes. The health impacts of floods are wide ranging, and depend on a number of factors. However, the health impacts of a particular flood are specific to the particular context. The immediate health impacts of floods include drowning, injuries, hypothermia, and animal bites. Health risks also are associated with the evacuation of patients, loss of health workers, and loss of health infrastructure including essential drugs and supplies. In the medium-term, infected wounds, complications of injury, poisoning, poor mental health, communicable diseases, and starvation are indirect effects of flooding. In the long-term, chronic disease, disability, poor mental health, and poverty-related diseases including malnutrition are the potential legacy. This article proposes a structured approach to the classification of the health impacts of floods and a conceptual framework that demonstrates the relationships between floods and the direct and indirect health consequences.

Climate change and human health: a One Health approach.

Patz, Jonathan A; Hahn, Micah B

Climate change adds complexity and uncertainty to human health issues such as emerging infectious diseases, food security, and national sustainability planning that intensify the importance of interdisciplinary and collaborative research. Collaboration between veterinary, medical, and public health professionals to understand the ecological interactions and reactions to flux in a system can facilitate clearer understanding of climate change impacts on environmental, animal, and human health. Here we present a brief introduction to climate science and projections for the next century and a review of current knowledge on the impacts of climate-driven environmental change on human health. We then turn to the links between ecological and evolutionary responses to climate change and health. The literature on climate impacts on biological systems is rich in both content and historical data, but the connections between these changes and human health is less understood. We discuss five mechanisms by which climate changes impacts on biological systems will be felt by the human population: Modifications in Vector, Reservoir, and Pathogen Lifecycles; Diseases of Domestic and Wild Animals and Plants; Disruption of Synchrony Between Interacting Species; Trophic Cascades; and Alteration or Destruction of Habitat. Each species responds to environmental changes differently, and in order to predict the movement of disease through ecosystems, we have to rely on expertise from the fields of veterinary, medical, and public health, and these health professionals must take into account the dynamic nature of ecosystems in a changing climate.

Ambient heat exposure is a well-known health hazard, which reduces human performance and work capacity at heat levels already common in tropical and subtropical areas. Various health problems have been reported. Increasing heat exposure during the hottest seasons of each year is a key feature of global climate change. Heat exhaustion and reduced human performance are often overlooked in climate change health impact analysis. Later this century, many among the four billion people who live in hot areas worldwide will experience significantly reduced work capacity owing to climate change. In some areas, 30-40% of annual daylight hours will become too hot for work to be carried out. The social and economic impacts will be considerable, with global gross domestic product (GDP) losses greater than 20% by 2100. The analysis to date is piecemeal. More analysis of climate change-related occupational health impact assessments is greatly needed.

Countries worldwide are challenged by health worker shortages, skill mix imbalances, and maldistribution. Human resources information systems (HRIS) are used to monitor and address these health workforce issues, but global understanding of such systems is minimal and baseline information regarding their scope and capability is practically non-existent. The Kenya Health Workforce Information System (KHWIS) has been identified as a promising example of a functioning HRIS. The objective of this paper is to document the impact of KHWIS data on human resources policy, planning and management. Sources for this study included semi-structured interviews with senior officials at Kenya's Ministry of Medical Services (MOMS), Ministry of Public Health and Sanitation (MOPHS), the Department of Nursing within MOMS, the Nursing Council of Kenya, Kenya Medical Practitioners and Dentists Board, Kenya's Clinical Officers Council, and Kenya Medical Laboratory Technicians and Technologists Board. Additionally, quantitative data were extracted from KHWIS databases to supplement the interviews. Health sector policy documents were retrieved from MOMS and MOPHS websites, and reviewed to assess whether they documented any changes to policy and practice as having been impacted by KHWIS data. Interviews with Kenyan government and regulatory officials cited health workforce data provided by KHWIS influenced policy, regulation, and management. Policy changes include extension of Kenya's age of mandatory civil service retirement from 55 to 60 years. Data retrieved from KHWIS document increased relicensing of professional nurses, midwives, medical practitioners and dentists, and interviewees reported this improved compliance raised professional regulatory body revenues. The review of Government records revealed few references to KHWIS; however, documentation specifically cited the KHWIS as having improved the availability of human resources for health information regarding workforce planning

Atmospheric composition of ambient air consists of different gases in definite proportion that affect the earth's climate and its ecological system. Due to varied anthropogenic reasons, this composition is changed, which ultimately have an impact on the health of living beings. For survival, the human respiratory system is one of the sensitive systems, which is easily and closely affected by the change in atmospheric composition of an external environment. Many studies have been conducted to quantify the effects of atmospheric pollution on human health by using different approaches. This article presents different scenario of studies conducted to evaluate the effects on different human groups. Differences between the studies conducted using spirometry and survey methods are presented in this article to extract a better sequence between these two methodologies. Many studies have been conducted to measure the respiratory status by evaluating the respiratory symptoms and hospital admissions. Limited numbers of studies are found with repeated spirometry on the same subjects for long duration to nullify the error arising due to decrease in efforts by the same subjects during manoeuvre of pulmonary function tests. Present study reveals the importance of methodological sequencing in order to obtain more authentic and reliable results. This study suggests that impacts of deteriorating atmospheric composition on human health can be more significantly studied if spirometry is done after survey analysis. The article also proposes that efficiency and authenticity of surveys involving health impacts will increase, if medical data information of patients is saved in hospitals in a proper format.

On the Impact to the Human Health from the Fukushima Nuclear Accident

International Nuclear Information System (INIS)

Simic, Zdenko

2014-01-01

Nuclear energy has long controversial history with hypes of utopian promises and doom fears; from 'electricity too cheap to meter' to the certain destruction of the world. Three major nuclear accidents (TMI, Chernobyl and Fukushima) helped only to strengthen mostly negative perception of the public. After TMI and Chernobyl understanding of the nuclear accidents impact to human health has considerably improved. This has helped to reduce uncertainty about risk estimates, but too little was achieved regarding the communication of how absolutely and relatively this risk is in fact small. Now with Fukushima there is new potential for even better understanding of the realistic scope of the total nuclear accident impact. Based on the experience with previous accidents obviously there are significant obstacles to achieve that. This paper is presenting current understanding of the impact on the human health from the Fukushima nuclear accident. Focus is given also to the uncertainties, perception, and relative prospective to other non radiation related risks. It is clear from data and assessments that immediate radiation related risk as well as expected long term health impact is even with conservative approach negligible and that it will be most probable impossible to determine it with health monitoring and epidemiological study. However, because of existing perception, lack of thrust and better approach many practical reactions are going to perpetuate negative picture, about radiation and nuclear energy, and perhaps cause some additional psychosocial risk. It is troubling that this induced risk is substantial and it could have been mainly prevented by timely applying experience form previous major accidents thru education, communication and transparency. Because of historical and local circumstance, communication difficulties and lack of sufficient understanding of uncertainties and magnitudes it seems that Fukushima nuclear accident will not be much better case

Understanding the mercury reduction issue: the impact of mercury on the environment and human health.

Kao, Richard T; Dault, Scott; Pichay, Teresa

2004-07-01

Mercury has been used in both medicine and dentistry for centuries. Recent media attention regarding the increased levels of mercury in dietary fish, high levels of mercury in air emissions, and conjecture that certain diseases may be caused by mercury exposure has increased public awareness of the potential adverse health effects of high doses of mercury. Dentistry has been criticized for its continued use of mercury in dental amalgam for both public health and environmental reasons. To address these concerns, dental professionals should understand the impact of the various levels and types of mercury on the environment and human health. Mercury is unique in its ability to form amalgams with other metals. Dental amalgam--consisting of silver, copper, tin, and mercury--has been used as a safe, stable, and cost-effective restorative material for more than 150 years. As a result of this use, the dental profession has been confronted by the public on two separate health issues concerning the mercury content in amalgam. The first issue is whether the mercury amalgamated with the various metals to create dental restorations poses a health issue for patients. The second is whether the scraps associated with amalgam placement and the removal of amalgam restorations poses environmental hazards which may eventually have an impact on human health. Despite the lack of scientific evidence for such hazards, there is growing pressure for the dental profession to address these health issues. In this article, the toxicology of mercury will be reviewed and the impact of amalgam on health and the environment will be examined.

Environmental Modeling and Bayesian Analysis for Assessing Human Health Impacts from Radioactive Waste Disposal

Stockton, T.; Black, P.; Tauxe, J.; Catlett, K.

Bayesian decision analysis provides a unified framework for coherent decision-making. Two key components of Bayesian decision analysis are probability distributions and utility functions. Calculating posterior distributions and performing decision analysis can be computationally challenging, especially for complex environmental models. In addition, probability distributions and utility functions for environmental models must be specified through expert elicitation, stakeholder consensus, or data collection, all of which have their own set of technical and political challenges. Nevertheless, a grand appeal of the Bayesian approach for environmental decision- making is the explicit treatment of uncertainty, including expert judgment. The impact of expert judgment on the environmental decision process, though integral, goes largely unassessed. Regulations and orders of the Environmental Protection Agency, Department Of Energy, and Nuclear Regulatory Agency orders require assessing the impact on human health of radioactive waste contamination over periods of up to ten thousand years. Towards this end complex environmental simulation models are used to assess "risk" to human and ecological health from migration of radioactive waste. As the computational burden of environmental modeling is continually reduced probabilistic process modeling using Monte Carlo simulation is becoming routinely used to propagate uncertainty from model inputs through model predictions. The utility of a Bayesian approach to environmental decision-making is discussed within the context of a buried radioactive waste example. This example highlights the desirability and difficulties of merging the cost of monitoring, the cost of the decision analysis, the cost and viability of clean up, and the probability of human health impacts within a rigorous decision framework.

Myers, Samuel S

2018-12-23

The impact of human activities on our planet's natural systems has been intensifying rapidly in the past several decades, leading to disruption and transformation of most natural systems. These disruptions in the atmosphere, oceans, and across the terrestrial land surface are not only driving species to extinction, they pose serious threats to human health and wellbeing. Characterising and addressing these threats requires a paradigm shift. In a lecture delivered to the Academy of Medical Sciences on Nov 13, 2017, I describe the scale of human impacts on natural systems and the extensive associated health effects across nearly every dimension of human health. I highlight several overarching themes that emerge from planetary health and suggest advances in the way we train, reward, promote, and fund the generation of health scientists who will be tasked with breaking out of their disciplinary silos to address this urgent constellation of health threats. I propose that protecting the health of future generations requires taking better care of Earth's natural systems. Copyright © 2017 Elsevier Ltd. All rights reserved.

Impact of environmental radiation on human health

A clean environment is essential for human health because the interaction between the environment and human health shows the complexity. Air pollution, less water quality, noise etc directly affects the health. Climate change, depletion of ozone layer, loss of biodiversity and degradation of land can also affect human health. Most of the modern technologies produce radiations in the environment having both beneficial and harmful effects through radioactive material. Natural radioactive sources include Cosmic radiation comes from the sun and outer space is absorbed by the atmosphere, a small amount reaches the earth's surface to which we are exposed. The exposure to this type of radiation is higher for people living above sea level. Radon is produced through the decay of uranium and thorium that are found naturally in the earth's crust. Primordial and terrestrial radiation are present in rocks and soils and occur when naturally radioactive isotopes of uranium, thorium and potassium decay within the earth's crust. Artificial (or man-made) radioactive sources include Fallout radiation, which results from past atmospheric nuclear bomb tests (1950s and 1960s many test explosions). Each environmental change, whether occurring as a natural phenomenon or through human intervention, changes the ecological balance and context within which disease hosts or vectors and parasites breed, develop, transmit disease. Today, radiation is a common used in medicine to diagnose illnesses, research to treat diseases and industry to generate electricity in nuclear power reactors. Radiation is energy that moves through space or matter at a very high speed. This energy can be in the form of particles, such as alpha or beta particles, which are emitted from radioisotopes. Radioactive Material is material that contains an unstable atomic nucleus releases radiation in the process of changing to a stable form. There are two types of health effects from radiation - threshold and non threshold

Full Text Available A number of serious studies have been conducted to decipher relationships between geological environment, potable/drinking water, and diseases as they were considered to have triggered suffering due to diseases among people. Chronic anemia can be caused by prolonged exposure to drinking water contaminated with cadmium (Cd. Under such circumstances, accumulation of Cd is manifested in the kidney, resulting in cancer and cardiovascular diseases. The aim of this study is to present the impact of Cd-contaminated drinking water on human health among the residents of villages in Winder. Collection of about 48 groundwater samples at an average distance of 1 to 2 km between the sampling sites has enabled a sufficient geological representation of distribution of minerals and elements in the samples. Concentration and comparison of Cd in the study area sample sites reveal highest values (24.2-30.0 ppb in the northeastern and southeastern sectors, covering parts of all three geological areas of Bela Ophiolite of Cretaceous age. Conducted questionnaire surveys provided relevance between cause and effect nature of Cd bearing diseases among which kidney, joint, and night blindness are more prominent. Due to this phenomena, toxic risk of Cd in drinking water was high as per calculated health hazard indices. The use of this water by the villagers may cause health problems and disorders among the inhabitants of the area.

There are rich deposits of mineral and fossil natural resources in the Arctic, which make this region very attractive for extracting industries. Their operations have immediate and vast consequences for ecological systems, which are particularly vulnerable in this region. We are developing a management strategy for Arctic watersheds impacted by industrial production. The case study is Lake Imandra watershed (Murmansk oblast, Russia) that has exceptionally high levels of economic development and large numbers of people living there. We track the impacts of toxic pollution on ecosystem health and then--human health. Three periods are identified: (a) natural, pre-industrial state; (b) disturbed, under rapid economic development; and (c) partial recovery, during recent economic meltdown. The ecosystem is shown to transform into a qualitatively new state, which is still different from the original natural state, even after toxic loadings have substantially decreased. Fish disease where analyzed to produce and integral evaluation of ecosystem health. Accumulation of heavy metals in fish is correlated with etiology of many diseases. Dose-effect relationships are between integral water quality indices and ecosystem health indicators clearly demonstrates that existing water quality standards adopted in Russia are inadequate for Arctic regions. Health was also poor for people drinking water from the Lake. Transport of heavy metals from drinking water, into human organs, and their effect on liver and kidney diseases shows the close connection between ecosystem and human health. A management system is outlined that is based on feedback from indices of ecosystem and human health and control over economic production and/or the amount of toxic loading produced. We argue that prospects for implementation of such a system are quite bleak at this time, and that more likely we will see a continued depopulation of these Northern regions.

Zhang, Na; Ju, Zhongjie; Zuo, Tao

There is growing recognition of the role of diet on modulating the composition and metabolic activity of the human gut microbiota, which in turn influence health. Dietary ingredients and food additives have a substantial impact on the gut microbiota and hence affect human health. Updates on current understanding of the gut microbiota in diseases and metabolic disorders are addressed in this review, providing insights into how this can be transferred from bench to bench side as gut microbes are integrated with food. The potency of microbiota-targeted biomarkers as a state-of-art tool for diagnosis of diseases was also discussed, and it would instruct individuals with healthy dietary consumption. Herein, recent advances in understanding the effect of diet on gut microbiota from an ecological perspective, and how these insights might promote health by guiding development of prebiotic and probiotic strategies and functional foods, were explored.

Full Text Available Fermented dairy products provide nutrients in our diet, some of which are produced by the action of microorganisms during fermentation. These products can be populated by a diverse microbiota that impacts the organoleptic and physicochemical characteristics foods as well as human health. Acidification is carried out by starter lactic acid bacteria (LAB whereas other LAB, moulds, and yeasts become dominant during ripening and contribute to the development of aroma and texture in dairy products. Probiotics are generally part of the nonstarter microbiota, and their use has been extended in recent years. Fermented dairy products can contain beneficial compounds, which are produced by the metabolic activity of their microbiota (vitamins, conjugated linoleic acid, bioactive peptides, and gamma-aminobutyric acid, among others. Some microorganisms can also release toxic compounds, the most notorious being biogenic amines and aflatoxins. Though generally considered safe, fermented dairy products can be contaminated by pathogens. If proliferation occurs during manufacture or storage, they can cause sporadic cases or outbreaks of disease. This paper provides an overview on the current state of different aspects of the research on microorganisms present in dairy products in the light of their positive or negative impact on human health.

The potential health impact of ambient ozone and PM2.5 concentrations modulated by climate change over the United States is investigated using combined atmospheric and health modeling. Regional air quality modeling for 2001 and 2050 was conducted using CMAQ Modeling System with meteorology from the GISS Global Climate Model, downscaled regionally using MM5,keeping boundary conditions of air pollutants, emission sources, population, activity levels, and pollution controls constant. BenMap was employed to estimate the air pollution health outcomes at the county, state, and national level for 2050 caused by the effect of meteorology on future ozone and PM2.5 concentrations. The changes in calculated annual mean PM2.5 concentrations show a relatively modest change with positive and negative responses (increasing PM2.5 levels across the northeastern U.S.) although average ozone levels slightly decrease across the northern sections of the U.S., and increase across the southern tier. Results suggest that climate change driven air quality-related health effects will be adversely affected in more then 2/3 of the continental U.S. Changes in health effects induced by PM2.5 dominate compared to those caused by ozone. PM2.5-induced premature mortality is about 15 times higher then that due to ozone. Nationally the analysis suggests approximately 4000 additional annual premature deaths due to climate change impacts on PM2.5 vs 300 due to climate change-induced ozone changes. However, the impacts vary spatially. Increased premature mortality due to elevated ozone concentrations will be offset by lower mortality from reductions in PM2.5 in 11 states. Uncertainties related to different emissions projections used to simulate future climate, and the uncertainties forecasting the meteorology, are large although there are potentially important unaddressed uncertainties (e.g., downscaling, speciation, interaction, exposure, and concentration-response function of the human health studies).

Urban Surface Water Quality, Flood Water Quality and Human Health Impacts in Chinese Cities. What Do We Know?

Directory of Open Access Journals (Sweden)

Yuhan Rui

2018-02-01

Full Text Available Climate change and urbanization have led to an increase in the frequency of extreme water related events such as flooding, which has negative impacts on the environment, economy and human health. With respect to the latter, our understanding of the interrelationship between flooding, urban surface water and human health is still very limited. More in-depth research in this area is needed to further strengthen the process of planning and implementation of responses to mitigate the negative health impacts of flooding in urban areas. The objective of this paper is to assess the state of the research on the interrelationship between surface water quality, flood water quality and human health in urban areas based on the published literature. These insights will be instrumental in identifying and prioritizing future research needs in this area. In this study, research publications in the domain of urban flooding, surface water quality and human health were collated using keyword searches. A detailed assessment of these publications substantiated the limited number of publications focusing on the link between flooding and human health. There was also an uneven geographical distribution of the study areas, as most of the studies focused on developed countries. A few studies have focused on developing countries, although the severity of water quality issues is higher in these countries. The study also revealed a disparity of research in this field across regions in China as most of the studies focused on the populous south-eastern region of China. The lack of studies in some regions has been attributed to the absence of flood water quality monitoring systems which allow the collection of real-time water quality monitoring data during flooding in urban areas. The widespread implementation of cost effective real-time water quality monitoring systems which are based on the latest remote or mobile phone based data acquisition techniques is recommended

Exposure to UV radiation and human health

This paper will overview the significant issues facing researchers in relating the impact of exposure to sunlight and human health. Exposure to solar ultraviolet radiation is the major causative factor in most sun-related skin and eye disorders, however, very little is known quantitatively about human UV exposures. Interestingly, human exposure to sunlight also has a nutritional impact, namely the development of pre-Vitamin D, which is an important nutrient in bone health. New research suggest that low vitamin D status may be a causative factor in the development of selective types of cancer and autoimminue diseases, as well as a contributing factor in bone health. The 'health duality' aspect of sunlight exposure is an interesting and controversial topic that is a research focus of Kimlin's research group.

The impact of residential combustion emissions on atmospheric aerosol, human health, and climate

Directory of Open Access Journals (Sweden)

2016-01-01

Full Text Available Combustion of fuels in the residential sector for cooking and heating results in the emission of aerosol and aerosol precursors impacting air quality, human health, and climate. Residential emissions are dominated by the combustion of solid fuels. We use a global aerosol microphysics model to simulate the impact of residential fuel combustion on atmospheric aerosol for the year 2000. The model underestimates black carbon (BC and organic carbon (OC mass concentrations observed over Asia, Eastern Europe, and Africa, with better prediction when carbonaceous emissions from the residential sector are doubled. Observed seasonal variability of BC and OC concentrations are better simulated when residential emissions include a seasonal cycle. The largest contributions of residential emissions to annual surface mean particulate matter (PM2.5 concentrations are simulated for East Asia, South Asia, and Eastern Europe. We use a concentration response function to estimate the human health impact due to long-term exposure to ambient PM2.5 from residential emissions. We estimate global annual excess adult (>  30 years of age premature mortality (due to both cardiopulmonary disease and lung cancer to be 308 000 (113 300–497 000, 5th to 95th percentile uncertainty range for monthly varying residential emissions and 517 000 (192 000–827 000 when residential carbonaceous emissions are doubled. Mortality due to residential emissions is greatest in Asia, with China and India accounting for 50 % of simulated global excess mortality. Using an offline radiative transfer model we estimate that residential emissions exert a global annual mean direct radiative effect between −66 and +21 mW m−2, with sensitivity to the residential emission flux and the assumed ratio of BC, OC, and SO2 emissions. Residential emissions exert a global annual mean first aerosol indirect effect of between −52 and −16 mW m−2, which is sensitive to the

2015-12-10

Global momentum around women's, children's, and adolescents' health, coupled with the ambitious and equalizing agenda of the Sustainable Development Goals (SDGs), has exposed a tension between the need for comprehensive, multi-actor, rights-based approaches that seek to "close the gaps" and a growing economic and political imperative to demonstrate efficiency, effectiveness, and returns on specific investments. To address this challenge, this paper proposes a framework to measure "results" in a way that offers a more nuanced understanding of the impact of human rights-based approaches and their complexity, as well as their contextual, multi-sectoral, and evolving nature. We argue that the impact of human rights-based approaches is best measured across a spectrum of change-at the individual, programmatic, structural, and societal levels. Such an analysis would allow for more accurate assessments of the cumulative effect of these changes. The paper also underscores the long-overdue need to better define the parameters of a human rights-based approach to health. This is an important part of the research agenda on human rights and health in the context of the SDGs and the Global Strategy for Women's, Children's and Adolescents' Health, and amid calls for better measurement and greater accountability for resources, results, and rights at all levels. While this paper focuses on women's, children's, and adolescents' health, the proposed framework can apply as readily to other areas of health and provides a new frame of reference for assessing the impact of human rights-based approaches.

One of the major environmental problems confronting Pakistan is water pollution. Human health is being affected by water pollution. The major sources of pollution for surface and groundwater resources are municipal sewage and industrial wastewater. The indiscriminate discharges of untreated sewage and industrial effluents into the water bodies have affected not only the water quality but also human health. Groundwater is also being contaminated by the discharge of untreated sewage into land. Water pollution is responsible for water borne diseases such as hepatitis, dysentery, typhoid, cholera, paratyphoid fever etc. This paper presents a general overview of the wastewater pollution in Pakistan, an evaluation and a specific reference to Lahore city and the effects on human health. Finally, sustainable treatment methods have been proposed to mitigate the water pollution problem. The analysis of water bodies at wastewater discharge points shows depletion of Dissolved Oxygen (DO) and high levels of E. Coli. There is an evidence of groundwater pollution in many areas due to the discharge of wastewater on open land. To protect the water sources from contamination, appropriate treatment methods/treatment technologies have also been discussed in this paper. In the end conclusion and recommendations are given.

Full Text Available Photoprotection messages and ‘SunSmart’ programmes exist mainly to prevent skin cancers and, more recently, to encourage adequate personal sun exposure to elicit a vitamin D response for healthy bone and immune systems. Several developed countries maintain intensive research networks and monitor solar UV radiation to support awareness campaigns and intervention development. The situation is different in sub-Saharan Africa. Adequate empirical evidence of the impact of solar UV radiation on human health, even for melanomas and cataracts, is lacking, and is overshadowed by other factors such as communicable diseases, especially HIV, AIDS and tuberculosis. In addition, the established photoprotection messages used in developed countries have been adopted and implemented in a limited number of sub-Saharan countries but with minimal understanding of local conditions and behaviours. In this review, we consider the current evidence for sun-related effects on human health in sub-Saharan Africa, summarise published research and identify key issues. Data on the prevalence of human diseases affected by solar UV radiation in all subpopulations are not generally available, financial support is insufficient and the infrastructure to address these and other related topics is inadequate. Despite these limitations, considerable progress may be made regarding the management of solar UV radiation related health outcomes in sub-Saharan Africa, provided researchers collaborate and resources are allocated appropriately.

One health and cyanobacteria in freshwater systems: animal illnesses and deaths are sentinel events for human health risks.

Hilborn, Elizabeth D; Beasley, Val R

2015-04-20

Harmful cyanobacterial blooms have adversely impacted human and animal health for thousands of years. Recently, the health impacts of harmful cyanobacteria blooms are becoming more frequently detected and reported. However, reports of human and animal illnesses or deaths associated with harmful cyanobacteria blooms tend to be investigated and reported separately. Consequently, professionals working in human or in animal health do not always communicate findings related to these events with one another. Using the One Health concept of integration and collaboration among health disciplines, we systematically review the existing literature to discover where harmful cyanobacteria-associated animal illnesses and deaths have served as sentinel events to warn of potential human health risks. We find that illnesses or deaths among livestock, dogs and fish are all potentially useful as sentinel events for the presence of harmful cyanobacteria that may impact human health. We also describe ways to enhance the value of reports of cyanobacteria-associated illnesses and deaths in animals to protect human health. Efficient monitoring of environmental and animal health in a One Health collaborative framework can provide vital warnings of cyanobacteria-associated human health risks.

The World Health Organization emphasized that climate change is a significant and emerging threat to public health, especially in lower income populations and tropical/subtropical countries. However, people in Asia and Africa were the least likely to perceive global warming as a threat. In Vietnam, little research has been conducted concerning the perceptions of effects of climate change on human health. The aim of this study was to explore the perceptions on climate change and its impact on human health among people in Hanoi. We applied a combined quantitative and qualitative approach to study perceptions on climate change among people in Hanoi. A total of 1,444 people were recruited, including 754 people living in non-slum areas and 690 people living in slum areas of Hanoi. A structured questionnaire was used to collect quantitative data on their perceptions. In a parallel qualitative study, two focus group discussions and 12 in-depth interviews (IDs) were carried out involving 24 people from both slum and non-slum areas. The majority of the respondents in the study had heard about climate change and its impact on human health (79.3 and 70.1% in non-slum and slum areas, respectively). About one third of the respondents reported that members of their family had experienced illness in the recent summer and winter compared to the same seasons 5 years ago. The most common symptoms reported during hot weather were headaches, fatigue, and dizziness; hypertension and other cardiovascular diseases were also reported. During cold weather, people reported experiencing cough, fever, and influenza, as well as pneumonia and emerging infectious diseases such as dengue and Japanese encephalitis. The observed high level of awareness on the links between climate change and human health may help to increase the success of the National Prevention Program on Climate Change. Moreover, understanding the concerns of the people may help policy makers to develop and implement effective

Full Text Available Background: The World Health Organization emphasized that climate change is a significant and emerging threat to public health, especially in lower income populations and tropical/subtropical countries. However, people in Asia and Africa were the least likely to perceive global warming as a threat. In Vietnam, little research has been conducted concerning the perceptions of effects of climate change on human health. Objective: The aim of this study was to explore the perceptions on climate change and its impact on human health among people in Hanoi. Design: We applied a combined quantitative and qualitative approach to study perceptions on climate change among people in Hanoi. A total of 1,444 people were recruited, including 754 people living in non-slum areas and 690 people living in slum areas of Hanoi. A structured questionnaire was used to collect quantitative data on their perceptions. In a parallel qualitative study, two focus group discussions and 12 in-depth interviews (IDs were carried out involving 24 people from both slum and non-slum areas. Results: The majority of the respondents in the study had heard about climate change and its impact on human health (79.3 and 70.1% in non-slum and slum areas, respectively. About one third of the respondents reported that members of their family had experienced illness in the recent summer and winter compared to the same seasons 5 years ago. The most common symptoms reported during hot weather were headaches, fatigue, and dizziness; hypertension and other cardiovascular diseases were also reported. During cold weather, people reported experiencing cough, fever, and influenza, as well as pneumonia and emerging infectious diseases such as dengue and Japanese encephalitis. Conclusions: The observed high level of awareness on the links between climate change and human health may help to increase the success of the National Prevention Program on Climate Change. Moreover, understanding the concerns of

In order to provide better sustainable groundwater quality management and minimize the impact of contamination in humans, improved understanding and quantification of the interaction between hydrogeological models, geological site information and human health are needed. Considering the joint influence of these components in the overall human health risk assessment and the corresponding sources of uncertainty aid decision makers to better allocate resources in data acquisition campaigns. This is important to (1) achieve remediation goals in a cost-effective manner, (2) protect human health and (3) keep water supplies clean in order to keep with quality standards. Such task is challenging since a full characterization of the subsurface is unfeasible due to financial and technological constraints. In addition, human exposure and physiological response to contamination are subject to uncertainty and variability. Normally, sampling strategies are developed with the goal of reducing uncertainty, but less often they are developed in the context of their impacts on the overall system uncertainty. Therefore, quantifying the impact from each of these components (hydrogeological, behavioral and physiological) in final human health risk prediction can provide guidance for decision makers to best allocate resources towards minimal prediction uncertainty. In this presentation, a multi-component human health risk-based framework is presented which allows decision makers to set priorities through an information entropy-based visualization tool. Results highlight the role of characteristic length-scales characterizing flow and transport in determining data needs within an integrated hydrogeological-health framework. Conditions where uncertainty reduction in human health risk predictions may benefit from better understanding of the health component, as opposed to a more detailed hydrogeological characterization, are also discussed. Finally, results illustrate how different dose

Coffee is one of the most widely consumed beverages throughout the world. So far, many studies have shown the properties of coffee beverages, but little is known about its impacts on human and environmental health from its discard in the environment. So, the present work aims to investigate the mutagenic, genotoxic, cytotoxic and ecotoxic effects of leached (LE) and solubilized (SE) extracts from coffee waste, simulating the disposal of this residue in landfills and via sewage systems, respectively. Chemical analyses were also carried out. LE and SE induced mutagenicity in the TA98 Salmonella strain with and without exogenous metabolization (S9). In the TA100 only SE induced mutagenicity, what was observed without S9. An increase in the frequency of micronuclei was observed in HepG2 cell line after 3 and 24h of exposure to both extracts. No cytotoxic effects were observed in HepG2 cells by WST-1 assay. The EC50 values for the LE and SE were 1.5% and 11.26% for Daphnia similis, 0.12% and 1.39% for Ceriodaphnia dubia and 6.0% and 5.5% for Vibrio fischeri, respectively. Caffeine and several transition metals were found in both extracts. Coffee waste discarded in the environment may pose a risk to human and environmental health, since this compound can cause DNA damage and present toxicity to aquatic organisms.

Resource recovery from sewage sludge has the potential to save natural resources, but the potential risks connected to human exposure to heavy metals, organic micropollutants, and pathogenic microorganisms attract stakeholder concern. The purpose of the presented study was to include pathogen risks to human health in life cycle assessment (LCA) of wastewater and sludge management systems, as this is commonly omitted from LCAs due to methodological limitations. Part 1 of this article series estimated the overall pathogen risk for such a system with agricultural use of the sludge, in a way that enables the results to be integrated in LCA. This article (part 2) presents a full LCA for two model systems (with agricultural utilization or incineration of sludge) to reveal the relative importance of pathogen risk in relation to other potential impacts on human health. The study showed that, for both model systems, pathogen risk can constitute an important part (in this study up to 20%) of the total life cycle impacts on human health (expressed in disability adjusted life years) which include other important impacts such as human toxicity potential, global warming potential, and photochemical oxidant formation potential.

Gut bacteria are an important component of the microbiota ecosystem in the human gut, which is colonized by 1014 microbes, ten times more than the human cells. Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function. However, they can also be potentially harmful due to the change of their composition when the gut ecosystem undergoes abnormal changes in the light of the use of antibiotics, illness, stress, aging, bad dietary habits, and lifestyle. Dysbiosis of the gut bacteria communities can cause many chronic diseases, such as inflammatory bowel disease, obesity, cancer, and autism. This review summarizes and discusses the roles and potential mechanisms of gut bacteria in human health and diseases. PMID:25849657

Vegetation including canopy, grasslands, and shrublands can directly sequester pollutants onto the plant surface, resulting in an improvement in air quality. Until now, several studies have estimated the pollution removal capacity of canopy cover at the level of a county, but no such work exists for grasslands and shrublands. This work quantifies the air pollution removal capacity of grasslands and shrublands at the county-level in the United States and estimates the human health benefits associated with pollution removal using the i-Tree Eco model. Sequestration of pollutants is estimated based on the Leaf Area Index (LAI) obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) derived dataset estimates of LAI and the percentage land cover obtained from the National Land Cover Database (NLCD) for the year 2010. Calculation of pollution removal capacity using local environmental data indicates that grasslands and shrublands remove a total of 6.42 million tonnes of air pollutants in the United States and the associated monetary benefits total 268 million. Human health impacts and associated monetary value due to pollution removal was observed to be significantly high in urban areas indicating that grasslands and shrublands are equally critical as canopy in improving air quality and human health in urban regions.

Plastic and Human Health: A Micro Issue?

Microplastics are a pollutant of environmental concern. Their presence in food destined for human consumption and in air samples has been reported. Thus, microplastic exposure via diet or inhalation could occur, the human health effects of which are unknown. The current review article draws upon cross-disciplinary scientific literature to discuss and evaluate the potential human health impacts of microplastics and outlines urgent areas for future research. Key literature up to September 2016 relating to accumulation, particle toxicity, and chemical and microbial contaminants was critically examined. Although microplastics and human health is an emerging field, complementary existing fields indicate potential particle, chemical and microbial hazards. If inhaled or ingested, microplastics may accumulate and exert localized particle toxicity by inducing or enhancing an immune response. Chemical toxicity could occur due to the localized leaching of component monomers, endogenous additives, and adsorbed environmental pollutants. Chronic exposure is anticipated to be of greater concern due to the accumulative effect that could occur. This is expected to be dose-dependent, and a robust evidence-base of exposure levels is currently lacking. Although there is potential for microplastics to impact human health, assessing current exposure levels and burdens is key. This information will guide future research into the potential mechanisms of toxicity and hence therein possible health effects.

Satellite imagery has greatly influenced our understanding of dust activity on a global scale. A number of different satellites such as NASA's Earth-Probe Total Ozone Mapping Spectrometer (TOMS) and Se-viewing Field-of-view Sensor (SeaWiFS) acquire daily global-scale data used to produce imagery for monitoring dust storm formation and movement. This global-scale imagery has documented the frequent transmission of dust storm-derived soils through Earth's atmosphere and the magnitude of many of these events. While various research projects have been undertaken to understand this normal planetary process, little has been done to address its impact on ocean and human health. This review will address the ability of dust storms to influence marine microbial population densities and transport of soil-associated toxins and pathogenic microorganisms to marine environments. The implications of dust on ocean and human health in this emerging scientific field will be discussed.

Nutrition, health and human rights.

Brundtland, G H

1999-07-01

This paper presents the speech delivered by Gro Harlem Brundtland, Director-General of WHO, on issues related to nutrition from a health and a human rights perspective. According to Brundtland, nutrition is a universal factor that both affects and defines the health of all people. It affects not only growth and physical development of a child, but also his cognitive and social development. However, inequity, poverty, underdevelopment, as well as inadequate access to food, health and care still exist which have resulted to the deaths of millions of children and left many more suffering from diseases. Poverty has also been identified as the main obstacle to the attainment of health. The existence of structural poverty and ill health eventually leads to poor development, which includes poor nutrition, poor health, and poor human rights. The impact of poverty on health is further worsened by discrimination on the basis of race, color, sex, language, or religion. To address this issue, the WHO will renew their focus on the political and legal links between health and human rights. A human rights perspective provides the international community with an opportunity to support the development of public health policies and practices that promote healthy nutrition as a center of all social and economic development.

Human health and diseases are determined by many complex factors. Health threats from the human-animal-ecosystems interface (HAEI) and zoonotic diseases (zoonoses) impose an increasing risk continuously to public health, from those emerging pathogens transmitted through contact with animals, food, water and contaminated environments. Immense challenges forced on the ecological perspectives on food and the eco-environments, including aquaculture, agriculture and the entire food systems. Impacts of food and eco-environments on human health will be examined amongst the importance of human interventions for intended purposes in lowering the adverse effects on the biodiversity. The complexity of relevant conditions defined as factors contributing to the ecological determinants of health will be illuminated from different perspectives based on concepts, citations, examples and models, in conjunction with harmful consequential effects of human-induced disturbances to our environments and food systems, together with the burdens from ecosystem disruption, environmental hazards and loss of ecosystem functions. The eco-health literacy should be further promoting under the "One Health" vision, with "One World" concept under Ecological Public Health Model for sustaining our environments and the planet earth for all beings, which is coincidentally echoing Confucian's theory for the environmental ethics of ecological harmony.

Role of Plastics on Human Health.

Plastics, currently the universal workhorse materials of modern economy, because of their low cost and varied functional properties are posing serious threat to environment and consumer's health in many direct and indirect ways. Rising concern about the impact of plastics on environment and human health, has forced the industry to look for alternatives. This review studies current understanding of benefits and concerns surrounding use of plastics, reviews literature about health effects in humans and discusses the current state of evidence, as well as future research trends. There is increasing concern regarding additives in plastics to which most people are exposed, such as phthalates, bisphenol A or polybrominated diphenyl ethers (PBDE), and their detection in humans, leading to harmful impact on health. The studies are divided, among many other issues on the fact of considering these additives as carcinogens or toxicants, but there is a consensus that these chemicals have the ability to alter the endocrine system. Human data are limited compared to large body of experimental evidence documenting reproductive or developmental toxicity in relation to these compounds in animals. The concentrations of these additives in young children, a segment particularly sensitive to exogenous insults, are typically higher, indicating the need to decrease exposure to these compounds. The rapid increase in usage of plastics and increased awareness about its health hazard has lent urgency to the whole issue.

Human rights violations have adverse consequences for health. However, to date, there remains little empirical evidence documenting this association, beyond the obvious physical and psychological effects of torture. The primary aim of this study was to investigate whether Australian asylum policies and practices, which arguably violate human rights, are associated with adverse health outcomes. We designed a mixed methods study to address the study aim. A cross-sectional survey was conducted with 71 Iraqi Temporary Protection Visa (TPV) refugees and 60 Iraqi Permanent Humanitarian Visa (PHV) refugees, residing in Melbourne, Australia. Prior to a recent policy amendment, TPV refugees were only given temporary residency status and had restricted access to a range of government funded benefits and services that permanent refugees are automatically entitled to. The quantitative results were triangulated with semi-structured interviews with TPV refugees and service providers. The main outcome measures were self-reported physical and psychological health. Standardised self-report instruments, validated in an Arabic population, were used to measure health and wellbeing outcomes. Forty-six percent of TPV refugees compared with 25% of PHV refugees reported symptoms consistent with a diagnosis of clinical depression (p = 0.003). After controlling for the effects of age, gender and marital status, TPV status made a statistically significant contribution to psychological distress (B = 0.5, 95% CI 0.3 to 0.71, p basic human rights, culminated in a strong sense of injustice. Government asylum policies and practices violating human rights norms are associated with demonstrable psychological health impacts. This link between policy, rights violations and health outcomes offers a framework for addressing the impact of socio-political structures on health.

Impacts of pavement types on in-vehicle noise and human health.

Noise is a major source of pollution that can affect the human physiology and living environment. According to the World Health Organization (WHO), an exposure for longer than 24 hours to noise levels above 70 dB(A) may damage human hearing sensitivity, induce adverse health effects, and cause anxiety to residents nearby roadways. Pavement type with different roughness is one of the associated sources that may contribute to in-vehicle noise. Most previous studies have focused on the impact of pavement type on the surrounding acoustic environment of roadways, and given little attention to in-vehicle noise levels. This paper explores the impacts of different pavement types on in-vehicle noise levels and the associated adverse health effects. An old concrete pavement and a pavement with a thin asphalt overlay were chosen as the test beds. The in-vehicle noise caused by the asphalt and concrete pavements were measured, as well as the drivers' corresponding heart rates and reported riding comfort. Results show that the overall in-vehicle sound levels are higher than 70 dB(A) even at midnight. The newly overlaid asphalt pavement reduced in-vehicle noise at a driving speed of 96.5 km/hr by approximately 6 dB(A). Further, on the concrete pavement with higher roughness, driver heart rates were significantly higher than on the asphalt pavement. Drivers reported feeling more comfortable when driving on asphalt than on concrete pavement. Further tests on more drivers with different demographic characteristics, along highways with complicated configurations, and an examination of more factors contributing to in-vehicle noise are recommended, in addition to measuring additional physical symptoms of both drivers and passengers. While there have been many previous noise-related studies, few have addressed in-vehicle noise. Most studies have focused on the noise that residents have complained about, such as neighborhood traffic noise. As yet, there have been no complaints by

Human body harbors diverse microbes, the main components include bacteria, eukaryotes and viruses. Emerging evidences show that the human microbiota is intrinsically linked with overall health. The development of next-generation sequencing provides an unprecedented opportunity to investigate the complex microbial communities that are associated with the human body. Many factors like host genetics and environmental factors have a major impact on the composition and dynamic changes of human microbiota. The purpose of this paper is to present an overview of the relationship between human health and human microbiota (skin, nasal, throat, oral, vaginal and gut microbiota), then to focus on the factors modulating the composition of the microbiota and the future challenges to manipulate the microbiota for personalized health.

Several recent initiatives such as Planetary Health , EcoHealth and One Health claim that human health depends on flourishing natural ecosystems. However, little has been said about the operational and implementation challenges of health-oriented conservation actions on the ground. We contend that ecological-epidemiological research must be complemented by a form of implementation science that examines: (i) the links between specific conservation actions and the resulting ecological changes, and (ii) how this ecological change impacts human health and well-being, when human behaviours are considered. Drawing on the policy evaluation tradition in public economics, first, we present three examples of recent social science research on conservation interventions that affect human health. These examples are from low- and middle-income countries in the tropics and subtropics. Second, drawing on these examples, we present three propositions related to impact evaluation and non-market valuation that can help guide future multidisciplinary research on conservation and human health. Research guided by these propositions will allow stakeholders to determine how ecosystem-mediated strategies for health promotion compare with more conventional biomedical prevention and treatment strategies for safeguarding health.This article is part of the themed issue 'Conservation, biodiversity and infectious disease: scientific evidence and policy implications'. © 2017 The Authors.

Impact of climate change on human infectious diseases: Empirical evidence and human adaptation.

Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events. It may lead to changes in health threat to human beings, multiplying existing health problems. This review examines the scientific evidences on the impact of climate change on human infectious diseases. It identifies research progress and gaps on how human society may respond to, adapt to, and prepare for the related changes. Based on a survey of related publications between 1990 and 2015, the terms used for literature selection reflect three aspects--the components of infectious diseases, climate variables, and selected infectious diseases. Humans' vulnerability to the potential health impacts by climate change is evident in literature. As an active agent, human beings may control the related health effects that may be effectively controlled through adopting proactive measures, including better understanding of the climate change patterns and of the compound disease-specific health effects, and effective allocation of technologies and resources to promote healthy lifestyles and public awareness. The following adaptation measures are recommended: 1) to go beyond empirical observations of the association between climate change and infectious diseases and develop more scientific explanations, 2) to improve the prediction of spatial-temporal process of climate change and the associated shifts in infectious diseases at various spatial and temporal scales, and 3) to establish locally effective early warning systems for the health effects of predicated climate change.

Scientific investigations have progressively refined our understanding of the influence of the environment on human health, and the many adverse impacts that human activities exert on the environment, from the local to the planetary level. Nonetheless, throughout the modern public health era, health has been pursued as though our lives and lifestyles are disconnected from ecosystems and their component organisms. The inadequacy of the societal and public health response to obesity, health inequities, and especially global environmental and climate change now calls for an ecological approach which addresses human activity in all its social, economic and cultural complexity. The new approach must be integral to, and interactive, with the natural environment. We see the continuing failure to truly integrate human health and environmental impact analysis as deeply damaging, and we propose a new conceptual model, the ecosystems-enriched Drivers, Pressures, State, Exposure, Effects, Actions or 'eDPSEEA' model, to address this shortcoming. The model recognizes convergence between the concept of ecosystems services which provides a human health and well-being slant to the value of ecosystems while equally emphasizing the health of the environment, and the growing calls for 'ecological public health' as a response to global environmental concerns now suffusing the discourse in public health. More revolution than evolution, ecological public health will demand new perspectives regarding the interconnections among society, the economy, the environment and our health and well-being. Success must be built on collaborations between the disparate scientific communities of the environmental sciences and public health as well as interactions with social scientists, economists and the legal profession. It will require outreach to political and other stakeholders including a currently largely disengaged general public. The need for an effective and robust science-policy interface has

Prominent Human Health Impacts from Several Marine Microbes: History, Ecology, and Public Health Implications

Directory of Open Access Journals (Sweden)

P. K. Bienfang

2011-01-01

Full Text Available This paper overviews several examples of important public health impacts by marine microbes and directs readers to the extensive literature germane to these maladies. These examples include three types of dinoflagellates (Gambierdiscus spp., Karenia brevis, and Alexandrium fundyense, BMAA-producing cyanobacteria, and infectious microbes. The dinoflagellates are responsible for ciguatera fish poisoning, neurotoxic shellfish poisoning, and paralytic shellfish poisoning, respectively, that have plagued coastal populations over time. Research interest on the potential for marine cyanobacteria to contribute BMAA into human food supplies has been derived by BMAA's discovery in cycad seeds and subsequent implication as the putative cause of amyotrophic lateral sclerosis/parkinsonism dementia complex among the Chamorro people of Guam. Recent UPLC/MS analyses indicate that recent reports that BMAA is prolifically distributed among marine cyanobacteria at high concentrations may be due to analyte misidentification in the analytical protocols being applied for BMAA. Common infectious microbes (including enterovirus, norovirus, Salmonella, Campylobacter, Shigella, Staphylococcus aureus, Cryptosporidium, and Giardia cause gastrointestinal and skin-related illness. These microbes can be introduced from external human and animal sources, or they can be indigenous to the marine environment.

Climate Change, Soils, and Human Health

Brevik, Eric C.

2013-04-01

According to the Intergovernmental Panel on Climate Change, global temperatures are expected to increase 1.1 to 6.4 degrees C during the 21st century and precipitation patterns will be altered by climate change (IPCC, 2007). Soils are intricately linked to the atmospheric/climate system through the carbon, nitrogen, and hydrologic cycles. Altered climate will, therefore, have an effect on soil processes and properties. Studies into the effects of climate change on soil processes and properties are still incomplete, but have revealed that climate change will impact soil organic matter dynamics including soil organisms and the multiple soil properties that are tied to organic matter, soil water, and soil erosion. The exact direction and magnitude of those impacts will be dependent on the amount of change in atmospheric gases, temperature, and precipitation amounts and patterns. Recent studies give reason to believe at least some soils may become net sources of atmospheric carbon as temperatures rise; this is particularly true of high latitude regions with permanently frozen soils. Soil erosion by both wind and water is also likely to increase. These soil changes will lead to both direct and indirect impacts on human health. Possible indirect impacts include temperature extremes, food safety and air quality issues, increased and/or expanded disease incidences, and occupational health issues. Potential direct impacts include decreased food security and increased atmospheric dust levels. However, there are still many things we need to know more about. How climate change will affect the nitrogen cycle and, in turn, how the nitrogen cycle will affect carbon sequestration in soils is a major research need, as is a better understanding of soil water-CO2 level-temperature relationships. Knowledge of the response of plants to elevated atmospheric CO2 given limitations in nutrients like nitrogen and phosphorus and how that affects soil organic matter dynamics is a critical

Full Text Available The most prevalent, curable sexually important diseases are those caused by Chlamydia trachomatis (C. trachomatis and genital mycoplasmas. An important characteristic of these infections is their ability to cause long-term sequels in upper genital tract, thus potentially affecting the reproductive health in both sexes. Pelvic inflammatory disease (PID, tubal factor infertility (TFI, and ectopic pregnancy (EP are well documented complications of C. trachomatis infection in women. The role of genital mycoplasmas in development of PID, TFI, and EP requires further evaluation, but growing evidence supports a significant role for these in the pathogenesis of chorioamnionitis, premature membrane rupture, and preterm labor in pregnant woman. Both C. trachomatis and genital mycoplasmas can affect the quality of sperm and possibly influence the fertility of men. For the purpose of this paper, basic, epidemiologic, clinical, therapeutic, and public health issue of these infections were reviewed and discussed, focusing on their impact on human reproductive health.

Oceans and Human Health: Microplastics and Harmful Algal Bloom

International Nuclear Information System (INIS)

Sombrito, Elvira Z.

2015-01-01

Traditionally the focus of research and concern of environmental studies in the marine system is the impact of human activities in the ocean: the sources, distribution and fate of pollutants resulting from human activities. More recently, there has been recognition of the potential direct impact health can come from eating contaminated seafood, swimming in polluted water, and exposure to toxins from harmful algal blooms. This paper will present two areas of concern that illustrates the fact that the health of the oceans and the health of humans go hand in hand: chemical pollution from plastics in the ocean and harmful alga bloom. The nuclear methodologies than can be useful in these areas will also be introduced. It is hoped that through the recognition of the inter-dependence of the health of both humans and the oceans, efforts will be made to restore and preserve the oceans. (author)

One health: The interface between veterinary and human health

Full Text Available One Health is an emerging global key concept integrating human and animal health through international research and policy. The complex relationships between the human and animal have resulted in a human-animal-environment interface since prehistorical times. The people, animals, plants, and the environment are so intrinsically linked that prevention of risks and the mitigation of effects of crises that originate at the interface between humans, animals, and their environments can only improve health and wellbeing. The “One Health” approach has been successfully implemented in numerous projects around the world. The containment of pandemic threats such as avian influenza and severe acute respiratory syndrome within months of outbreak are few examples of successful applications of the One Health paradigm. The paper begins with a brief overview of the human-animal interface and continues with the socio-economic and public health impact caused by various zoonotic diseases such as Middle East respiratory syndrome, Influenza, and Ebola virus. This is followed by the role of “One Health” to deal the global problem by the global solution. It emphasizes the interdisciplinary collaboration, training for health professionals and institutional support to minimize global health threats due to infectious diseases. The broad definition of the concept is supposed to lead multiple interpretations that impede the effective implementation of One Health approach within veterinary profession, within the medical profession, by wildlife specialists and by environmentalists, while on the other side, it gives a value of interdisciplinary collaboration for reducing threats in human-animal-environment interface.

A summary of LED lighting impacts on health

Full Text Available Lighting can affect the health of people in buildings. This goes beyond the safety aspects of providing enough illumination to see by; lighting affects mood and human circadian rhythms, while poor lighting can cause glare, headaches, eyestrain, aches and pains associated with poor body posture or, in extreme cases, skin conditions and various types of sight loss. These aspects ought to be considered by designers and building owners and occupiers in order to improve the lit environment and use adequate lighting and lighting controls that meet the recommendations of codes and standards. Various types of lighting can have different impacts depending on their spectral, optical and electrical characteristics. This paper discusses potential impacts of LED lighting on human health, and is based on a recent BRE review of research investigating the most typical effects of lighting on human health.

Bisphenol A (BPA), identified as an endocrine disruptor, is an industrially important chemical that is used as a raw material in the manufacture of many products such as engineering plastics (e.g., epoxy resins/polycarbonate plastics), food cans (i.e., lacquer coatings), and dental composites/sealants. The demand and production capacity of BPA in China have grown rapidly. This trend will lead to much more BPA contamination in the environmental media and in the general population in China. This paper reviews the current literature concerning the pollution status of BPA in China (the mainland, Hong Kong, and Taiwan) and its potential impact on human health. Due to potential human health risks from long-term exposure to BPA, body burden of the contaminant should be monitored. Copyright © 2011 Elsevier Ltd. All rights reserved.

Human health impacts for renewable energy scenarios from the EnerGEO Platform of Integrated Assessment (PIA)

Lefevre, Mireille; Gschwind, Benoit; Blanc, Isabelle; Ranchin, Thierry; Cofala, Janusz; Fuss, Sabine

2013-01-01

This article reports impact results from running the EnerGEO Platform of Integrated Assessment (PIA) related to human health for different scenarios in Europe. The scenarios were prepared within the EnerGEO project. The idea of this European project is to determine how low carbon scenarios, and in particular scenarios with a high share of renewable energy, affect concentrations of air pollutants and as a consequence affect human health. PM 2.5 concentrations were estimated with the IIASA Greenhouse Gas and Air Pollution Interactions and Synergies (GAINS) model on a time horizon up to the year 2050 for different scenarios. We analyse here the estimation of the Loss of Life Expectancy due to PM 2.5 concentrations for the Baseline scenario taken as a reference and the Maximum renewable power scenario. (orig.)

Human health and wellbeing in environmental impact assessment in New South Wales, Australia: Auditing health impacts within environmental assessments of major projects

International Nuclear Information System (INIS)

Harris, Patrick J.; Harris, Elizabeth; Thompson, Susan; Harris-Roxas, Ben; Kemp, Lynn

2009-01-01

Internationally the inclusion of health within environmental impact assessment (EIA) has been shown to be limited. While Australian EIA documentation has not been studied empirically to date, deficiencies in practice have been documented. This research developed an audit tool to undertake a qualitative descriptive analysis of 22 Major Project EAs in New South Wales, Australia. Results showed that health and wellbeing impacts were not considered explicitly. They were, however, included indirectly in the identification of traditional public health exposures associated with the physical environment and to a lesser extent the inclusion of social and economic impacts. However, no health data was used to inform any of the assessments, there was no reference to causal pathways between exposures or determinants and physical or mental health effects, and there was no inclusion of the differential distribution of exposures or health impacts on different populations. The results add conceptually and practically to the long standing integration debate, showing that health is in a position to add value to the EIA process as an explicit part of standard environmental, social and economic considerations. However, to overcome the consistently documented barriers to integrating health in EIA, capacity must be developed amongst EIA professionals, led by the health sector, to progress health related knowledge and tools.

Arms trade and its impact on global health.

The most obvious adverse impact of the arms trade on health is loss of life and maiming from the use of weapons in conflicts. Wealthy countries suffer damage to their health and human services when considerable resources are diverted to military expenditure. However, the relative impact of military expenditures and conflict on third world countries is much greater, and often devastating, by depriving a significant portion of the population of essential food, medicine, shelter, education, and economic opportunities. Further, the physical and psychological damage inflicted specifically on children is debilitating - through loss of (or separation from) families, loss of education, destruction of homes, exposure to murder and other violence, sexual abuse, abduction, torture, slavery, and forcible conscription as soldiers. This article outlines the socio-economic impact of the global arms trade in general and the damage done to human health and the environment, specifically.

Urban Green Space and Its Impact on Human Health

Kondo, Michelle C.; Fluehr, Jaime M.; McKeon, Thomas; Branas, Charles C.

2018-01-01

Background: Over half of the world’s population now lives in urban areas, and this proportion is expected to increase. While there have been numerous reviews of empirical studies on the link between nature and human health, very few have focused on the urban context, and most have examined almost exclusively cross-sectional research. This review is a first step toward assessing the possibility of causal relationships between nature and health in urban settings. Methods: Through systematic review of published literature, we explored the association between urban green space and human health. Results: We found consistent negative association between urban green space exposure and mortality, heart rate, and violence, and positive association with attention, mood, and physical activity. Results were mixed, or no association was found, in studies of urban green space exposure and general health, weight status, depression, and stress (via cortisol concentration). The number of studies was too low to generalize about birth outcomes, blood pressure, heart rate variability, cancer, diabetes, or respiratory symptoms. Conclusions: More studies using rigorous study design are needed to make generalizations, and meta-analyses, of these and other health outcomes possible. These findings may assist urban managers, organizations, and communities in their efforts to increase new or preserve existing green space. PMID:29510520

Potential Environmental and Human Health Impacts of Rechargeable Lithium Batteries in Electronic Waste

Kang, Daniel Hsing Po; Chen, Mengjun; Ogunseitan, Oladele A.

2013-01-01

Rechargeable lithium-ion (Li-ion) and lithium-polymer (Li-poly) batteries have recently become dominant in consumer electronic products because of advantages associated with energy density and product longevity. However, the small size of these batteries, the high rate of disposal of consumer products in which they are used, and the lack of uniform regulatory policy on their disposal means that lithium batteries may contribute substantially to environmental pollution and adverse human health impacts due to potentially toxic materials. In this research, we used standardized leaching tests, life-cycle impact assessment (LCIA), and hazard assessment models to evaluate hazardous waste classification, resource depletion potential, and toxicity potentials of lithium batteries used in cellphones. Our results demonstrate that according to U.S. federal regulations, defunct Li-ion batteries are classified hazardous due to their lead (Pb) content (average 6.29 mg/L; σ = 11.1; limit 5). However, according to California regulations, all lithium batteries tested are classified hazardous due to excessive levels of cobalt (average 163 544 mg/kg; σ = 62 897; limit 8000), copper (average 98 694 mg/kg; σ = 28 734; limit 2500), and nickel (average 9525 mg/kg; σ = 11 438; limit 2000). In some of the Li-ion batteries, the leached concentrations of chromium, lead, and thallium exceeded the California regulation limits. The environmental impact associated with resource depletion and human toxicity is mainly associated with cobalt, copper, nickel, thallium, and silver, whereas the ecotoxicity potential is primarily associated with cobalt, copper, nickel, thallium, and silver. However, the relative contribution of aluminum and lithium to human toxicity and ecotoxicity could not be estimated due to insufficient toxicity data in the models. These findings support the need for stronger government policy at the local, national, and international levels to encourage recovery, recycling, and

How have Global Health Initiatives impacted on health equity?

Science.gov (United States)

Hanefeld, Johanna

2008-01-01

This review examines the impact of Global Health Initiatives (GHIs) on health equity, focusing on low- and middle-income countries. It is a summary of a literature review commissioned by the WHO Commission on the Social Determinants of Health. GHIs have emerged during the past decade as a mechanism in development assistance for health. The review focuses on three GHIs, the US President's Emergency Plan For AIDS Relief (PEPFAR), the World Bank's Multi-country AIDS Programme (MAP) and the Global Fund to Fight AIDS, TB and Malaria. All three have leveraged significant amounts of funding for their focal diseases - together these three GHIs provide an estimated two-thirds of external resources going to HIV/AIDS. This paper examines their impact on gender equity. An analysis of these Initiatives finds that they have a significant impact on health equity, including gender equity, through their processes of programme formulation and implementation, and through the activities they fund and implement, including through their impact on health systems and human resources. However, GHIs have so far paid insufficient attention to health inequities. While increasingly acknowledging equity, including gender equity, as a concern, Initiatives have so far failed to adequately translate this into programmes that address drivers of health inequity, including gender inequities. The review highlights the comparative advantage of individual GHIs, which point to an increased need for, and continued difficulties in, harmonisation of activities at country level. On the basis of this comparative analysis, key recommendations are made. They include a call for equity-sensitive targets, the collection of gender-disaggregated data, the use of policy-making processes for empowerment, programmes that explicitly address causes of health inequity and impact assessments of interventions' effect on social inequities.

Studies on the precise impact of environmental pollutants on human health are difficult to undertake and interpret, because many genetic and environmental factors influence health at the same time and to varying degrees. Our chapter in the AMAP report was based on new approaches to describe risks and future needs. In this paper, we will introduce the issues associated with risk assessment of single chemicals, and present suggestions for future studies as well as a summary of lessons learned during the health-related parts of the European Union-funded FP7 project ArcRisk (Arctic Health Risks: Impacts on health in the Arctic and Europe owing to climate-induced changes in contaminant cycling, 2009-2014; www.arcrisk.eu).

Health impacts of coal: facts and fallacies

Energy Technology Data Exchange (ETDEWEB)

Finkelman, R.B. [University of Texas, Dallas, TX (United States)

2007-02-15

Coal has contributed enormously to the advance of civilization by providing an abundant, inexpensive, and convenient source of energy. Concurrent with its contributions, coal has extracted a high cost in terms of environmental damage and human health impacts. Unfortunately, the links between coal use and human health are distorted by a great deal of ignorance and misinformation. This paper discusses the facts and fallacies of the direct health impacts caused by coal. These include health problems caused by arsenic, fluorine, mercury and selenium released in coal use in the residential sector. The trace element iodine however may help prevent iodine deficiency disorder. Lignite in the ground in some Balkan areas has been associated with a urinary tract cancer known as Balkan endemic nephropathy (BEN). Uncontrolled burning coal seams and coal waste piles contribute to global warming and to respiratory problems. The 10-fold enrichment of trace elements in fly ash and the fine particles released from power plants could present a health threat but where good pollution control technology and disposal practices are applied the health threat is probably minimal. Radioactivity levels in coal are thought to be too low to cause concern. 27 refs., 2 figs.

In both ambient air pollution epidemiology and health impact assessment an accurate assessment of the population exposure is crucial. Although considerable advances have been made in assessing human exposure outdoors, the assessments often do not consider the impact of individual travel behavior on such exposures. Population-based exposures to NO 2 and O 3 using only home addresses were compared with models that integrate all time-activity patterns—including time in commute—for Flanders and Brussels. The exposure estimates were used to estimate the air pollution impact on years of life lost due to respiratory mortality. Health impact of NO 2 using an exposure that integrates time-activity information was on average 1.2% higher than when assuming that people are always at their home address. For ozone the overall estimated health impact was 0.8% lower. Local differences could be much larger, with estimates that differ up to 12% from the exposure using residential addresses only. Depending on age and gender, deviations from the population average were seen. Our results showed modest differences on a regional level. At the local level, however, time-activity patterns indicated larger differences in exposure and health impact estimates, mainly for people living in more rural areas. These results suggest that for local analyses the dynamic approach can contribute to an improved assessment of the health impact of various types of pollution and to the understanding of exposure differences between population groups. - Highlights: ► Exposure to ambient air pollution was assessed integrating population mobility. ► This dynamic exposure was integrated into a health impact assessment. ► Differences between the dynamic and residential exposure were quantified. ► Modest differences in health impact were found at a regional level. ► At municipal level larger differences were found, influenced by gender and age.

Decentralization's impact on the health workforce: Perspectives of managers, workers and national leaders

Full Text Available Abstract Designers and implementers of decentralization and other reform measures have focused much attention on financial and structural reform measures, but ignored their human resource implications. Concern is mounting about the impact that the reallocation of roles and responsibilities has had on the health workforce and its management, but the experiences and lessons of different countries have not been widely shared. This paper examines evidence from published literature on decentralization's impact on the demand side of the human resource equation, as well as the factors that have contributed to the impact. The elements that make such an impact analysis exceptionally complex are identified. They include the mode of decentralization that a country is implementing, the level of responsibility for the salary budget and pay determination, and the civil service status of transferred health workers. The main body of the paper is devoted to examining decentralization's impact on human resource issues from three different perspectives: that of local health managers, health workers themselves, and national health leaders. These three groups have different concerns in the human resource realm, and consequently, have been differently affected by decentralization processes. The paper concludes with recommendations regarding three key concerns that national authorities and international agencies should give prompt attention to. They are (1 defining the essential human resource policy, planning and management skills for national human resource managers who work in decentralized countries, and developing training programs to equip them with such skills; (2 supporting research that focuses on improving the knowledge base of how different modes of decentralization impact on staffing equity; and (3 identifying factors that most critically influence health worker motivation and performance under decentralization, and documenting the most cost-effective best

Health impact and damage cost assessment of pesticides in Europe.

Science.gov (United States)

Fantke, Peter; Friedrich, Rainer; Jolliet, Olivier

2012-11-15

Health impacts from pesticide use are of continuous concern in the European population, requiring a constant evaluation of European pesticide policy. However, health impacts have never been quantified accounting for specific crops contributing differently to overall human exposure as well as accounting for individual substances showing distinct environmental behavior and toxicity. We quantify health impacts and related damage costs from exposure to 133 pesticides applied in 24 European countries in 2003 adding up to almost 50% of the total pesticide mass applied in that year. Only 13 substances applied to 3 crop classes (grapes/vines, fruit trees, vegetables) contribute to 90% of the overall health impacts of about 2000 disability-adjusted life years in Europe per year corresponding to annual damage costs of 78 million Euro. Considering uncertainties along the full impact pathway mainly attributable to non-cancer dose-response relationships and residues in treated crops, we obtain an average burden of lifetime lost per person of 2.6 hours (95% confidence interval between 22 seconds and 45.3 days) or costs per person over lifetime of 12 Euro (95% confidence interval between 0.03 Euro and 5142 Euro), respectively. 33 of the 133 assessed substances accounting for 20% of health impacts in 2003 are now banned from the European market according to current legislation. The main limitation in assessing human health impacts from pesticides is related to the lack of systematic application data for all used substances. Since health impacts can be substantially influenced by the choice of pesticides, the need for more information about substance application becomes evident. Copyright © 2012 Elsevier Ltd.

Mutagenesis and teratogenesis as end points in health impact assessment

International Nuclear Information System (INIS)

Bender, M.A.

1976-01-01

The genetic and teratogenic effects of agents released to the environment as a consequence of energy production are exceedingly difficult to evaluate. Nevertheless, these effects on human health may be very costly in the context of cost-benefit analysis. In fact, the procedures required to limit mutagenic or teratogenic agents to the levels considered acceptable by regulatory bodies may constitute a major fraction of the cost of energy, especially where prudence dictates that a lack of empirical data requires extremely conservative regulations. Experience with ionizing radiation and with regulation of nuclear power installations illustrates the difficulty of genetic and teratogenic health impact assessment and the great uncertainties involved, as well as the influence of these impacts on the regulatory process and the consequent increased cost of power from this source. Data on genetic and teratogenic impacts on human health from chemical agents released to the environment by other energy technologies are much less complete, and, because of the large number of potentially active agents involved, it is evident that generic solutions to health impact assessment will be required to evaluate these energy alternatives

The Impact of Future Emissions Changes on Air Pollution Concentrations and Related Human Health Effects

Mikolajczyk, U.; Suppan, P.; Williams, M.

2015-12-01

Quantification of potential health benefits of reductions in air pollution on the local scale is becoming increasingly important. The aim of this study is to conduct health impact assessment (HIA) by utilizing regionally and spatially specific data in order to assess the influence of future emission scenarios on human health. In the first stage of this investigation, a modeling study was carried out using the Weather Research and Forecasting (WRF) model coupled with Chemistry to estimate ambient concentrations of air pollutants for the baseline year 2009, and for the future emission scenarios in southern Germany. Anthropogenic emissions for the baseline year 2009 are derived from the emission inventory provided by the Netherlands Organization of Applied Scientific Research (TNO) (Denier van der Gon et al., 2010). For Germany, the TNO emissions were replaced by gridded emission data with a high spatial resolution of 1/64 x 1/64 degrees. Future air quality simulations are carried out under different emission scenarios, which reflect possible energy and climate measures in year 2030. The model set-up included a nesting approach, where three domains with horizontal resolution of 18 km, 6 km and 2 km were defined. The simulation results for the baseline year 2009 are used to quantify present-day health burdens. Concentration-response functions (CRFs) for PM2.5 and NO2 from the WHO Health risks of air Pollution in Europe (HRAPIE) project were applied to population-weighted mean concentrations to estimate relative risks and hence to determine numbers of attributable deaths and associated life-years lost. In the next step, future health impacts of projected concentrations were calculated taking into account different emissions scenarios. The health benefits that we assume with air pollution reductions can be used to provide options for future policy decisions to protect public health.

The purpose is not to provide a comprehensive plan (e.g. the economic impact of ticks on human society is not included), instead we wish to describe a series of indices that would be helpful by obtaining homogeneous comparisons of impact and vulnerability exerted by ticks in different regions, countries or continents, using normalized sets of population, vegetation, climate and physical attributes of the territory. Three tick species, i.e. Dermacentor marginatus, Rhipicephalus turanicus and Hyalomma marginatum, have been traced over the territory of Spain to further explain the computation of these indices. The discussion is based on tick habitat suitability, used as a measure of the abiotic (climate) fitness of the habitat for the species in question, and the sensitivity of each tick species to the rate of change of habitat suitability with respect to climate change. The impact is the rate of change in habitat suitability weighted with a fuzzy logic function evaluating the total number of people in an area, percent of rural population and accessibility of the geographical divisions (expressed as hexagons with a 10 km radius) used in the study. The different climate scenarios evaluated in relation to ticks show that the north-western part of Spain would suffer the greatest impact in case the mean temperature would increase, while the Mediterranean region would suffer the highest impact if temperatures decreased. Vulnerability, based on the sanitary structure of the territory and on the impact on human activities due to the change in tick distribution and abundance, is proposed as a measure of adaptation of society to these climate scenarios. The cost is evaluated as a function of land use and tick habitat suitability in a buffer zone surrounding each geographic division. All indices proposed have been obtained by search of common and/or publicly

Climate change is widely acknowledged as a key global challenge for the 21st century, and is projected to significantly affect population health and human well-being. All of the climate change-related changes in weather patterns will affect human health, from boosting mental well-being to mortality from largescale disasters. Human health can be affected both directly and indirectly. For various reasons, the health sector has been slow in responding to the projected health impacts of climate c...

Northern Rivers Basins ecological and human health studies : summary, relevance and recommendations

International Nuclear Information System (INIS)

1999-04-01

Residents in northern Alberta expressed concerns that the original Northern River Basins Study (NRBS) only examined the impacts of contaminants on ecological health and did not include impacts on human health. In response to these concerns, Alberta Health established the Northern River Basins Human Health Monitoring Program in 1994 to investigate the possible relationships between various environmental risk factors and the health of northern residents in the province. This document links the ecological information collected by the original NRBS program with the information provided by the health program. Issues regarding health impacts from pulp mills and oil sand mining were also discussed. The findings of the health program were summarized and recommendations were made for future studies. The contaminants of potential concern (COPC) arising from the original NRBS were described in terms of their sources and any known connections between exposure and human health. The COPCs included arsenic, dioxins, chlorinated furans, polycyclic aromatic hydrocarbons (PAH) polychlorinated biphenyls (PCB) mercury, chlorinated phenolics, toxaphene, carbon monoxide, nitrogen oxides, ozone, sulphur dioxide, acid sulphates and particulate matter. Examples of Canadian regulatory criteria for these contaminants were also presented. 41 refs., 1 tab

'Only connect': the case for public health humanities.

Saffran, Lise

2014-12-01

Humanities in health has until now been primarily understood to mean humanities in medicine and has generally failed to include public health. I will argue in this paper that the common justifications for the former--including increased empathy among practitioners--are at least as applicable, if not more, to the latter. Growing emphasis on the social determinants of health and cultural competency in public health require public health students and professionals to develop a nuanced understanding of the influence of social context on health behaviour and to empathise with people in difficult circumstances. Literary fiction has been demonstrated to have an impact on skills related to empathy and social intelligence. Further, translating epidemiological evidence into public policy is a core task of public health and there is a growing body of research to indicate that statistical evidence is more persuasive when combined with narrative evidence. In this article I explore similarities and differences between proposed humanities in public health and programmes in humanities in medicine and highlight research gaps and possible implications of a more expansive view of humanities in health.

Fighting ambient air pollution and its impact on health: from human rights to the right to a clean environment.

Science.gov (United States)

Guillerm, N; Cesari, G

2015-08-01

Clean air is one of the basic requirements of human health and well-being. However, almost nine out of 10 individuals living in urban areas are affected by air pollution. Populations living in Africa, South-East Asia, and in low- and middle-income countries across all regions are the most exposed. Exposure to outdoor air pollution ranks as the ninth leading risk factor for mortality, killing 3.2 million people each year, especially young children, the elderly, persons with lung or cardiovascular disease, those who work or exercise outdoors and low-income populations. In October 2013, the International Agency for Research on Cancer (IARC) classified outdoor air pollution as carcinogenic to humans, calling air pollution 'a major environmental health problem'. Human rights and environmental norms are powerful tools to combat air pollution and its impact on health. The dependence of human rights on environmental quality has been recognised in international texts and by human rights treaty bodies. The growing awareness of the environment has already yielded considerable legislative and regulatory output. However, the implementation of standards remains a pervasive problem. In the fight against violations of norms, citizens have a crucial role to play. We discuss the relevance of a yet to be proclaimed standalone right to a healthy environment.

Higher intakes of red and processed meat are associated with poorer health outcomes and negative environmental impacts. Drawing upon a population survey the present paper investigates meat consumption behaviours, exploring perceived impacts for human health, animal welfare and the environment. Structured self-completion postal survey relating to red and processed meat, capturing data on attitudes, sustainable meat purchasing behaviour, red and processed meat intake, plus sociodemographic characteristics of respondents. Urban and rural districts of Nottinghamshire, East Midlands, UK, drawn from the electoral register. UK adults (n 842) aged 18-91 years, 497 females and 345 males, representing a 35·6 % response rate from 2500 randomly selected residents. Women were significantly more likely (P60 years) were more likely to hold positive attitudes towards animal welfare (Psustainability. Policy makers, nutritionists and health professionals need to increase the public's awareness of the environmental impact of eating red and processed meat. A first step could be to ensure that dietary guidelines integrate the nutritional, animal welfare and environmental components of sustainable diets.

Strategies to enhance the impact of research on human resources for health on policy making

Directory of Open Access Journals (Sweden)

Taghreed Adam

2011-06-01

Full Text Available Despite global recognition of the importance of human resources for health (HRH in achieving health system goals, very little is known about what works, for whom and under what circumstances, especially for low-income and middleincome countries. Several important events and reports have called for increased funding and capacity for HRH research in recent years and several initiatives have started as a result. Progress has been slow, however. The following strategies can be most valuable in ensuring the relevance of the generated evidence for decision making and its contribution to stronger health systems. The first is to promote national processes to set priorities for HRH research with active participation from decision makers. The second is to make conscious efforts to scale up primary research to address priority questions and to develop sustainable mechanisms to evaluate the impact of current or new HRH strategies to feed into the policy making process. The third is to invest in the development of systematic reviews to synthesize available evidence and in the adaptation of the underlying methods to make them more responsive to the type of questions and the nature of research involving HRH issues. The fourth and most important is to consistently use a systems approach in framing and addressing research questions. While a narrow approach may be more attractive and simple, health systems and the problems facing them are not. Increasing the body of evidence that takes into account the complexity of health systems, and particularly human resources for health, will advance knowledge in this area and will make big strides in the quality and usefulness of the generated evidence.

A review of waste management practices and their impact on human health

International Nuclear Information System (INIS)

Giusti, L.

2009-01-01

This work reviews (i) the most recent information on waste arisings and waste disposal options in the world, in the European Union (EU), in Organisation for Economic Co-operation and Development (OEDC) countries, and in some developing countries (notably China) and (ii) the potential direct and indirect impact of waste management activities on health. Though the main focus is primarily on municipal solid waste (MSW), exposure to bioaerosols from composting facilities and to pathogens from sewage treatment plants are considered. The reported effects of radioactive waste are also briefly reviewed. Hundreds of epidemiological studies reported on the incidence of a wide range of possible illnesses on employees of waste facilities and on the resident population. The main conclusion of the overall assessment of the literature is that the evidence of adverse health outcomes for the general population living near landfill sites, incinerators, composting facilities and nuclear installations is usually insufficient and inconclusive. There is convincing evidence of a high risk of gastrointestinal problems associated with pathogens originating at sewage treatment plants. In order to improve the quality and usefulness of epidemiological studies applied to populations residing in areas where waste management facilities are located or planned, preference should be given to prospective cohort studies of sufficient statistical power, with access to direct human exposure measurements, and supported by data on health effect biomarkers and susceptibility biomarkers.

In both ambient air pollution epidemiology and health impact assessment an accurate assessment of the population exposure is crucial. Although considerable advances have been made in assessing human exposure outdoors, the assessments often do not consider the impact of individual travel behavior on such exposures. Population-based exposures to NO{sub 2} and O{sub 3} using only home addresses were compared with models that integrate all time-activity patterns-including time in commute-for Flanders and Brussels. The exposure estimates were used to estimate the air pollution impact on years of life lost due to respiratory mortality. Health impact of NO{sub 2} using an exposure that integrates time-activity information was on average 1.2% higher than when assuming that people are always at their home address. For ozone the overall estimated health impact was 0.8% lower. Local differences could be much larger, with estimates that differ up to 12% from the exposure using residential addresses only. Depending on age and gender, deviations from the population average were seen. Our results showed modest differences on a regional level. At the local level, however, time-activity patterns indicated larger differences in exposure and health impact estimates, mainly for people living in more rural areas. These results suggest that for local analyses the dynamic approach can contribute to an improved assessment of the health impact of various types of pollution and to the understanding of exposure differences between population groups. - Highlights: Black-Right-Pointing-Pointer Exposure to ambient air pollution was assessed integrating population mobility. Black-Right-Pointing-Pointer This dynamic exposure was integrated into a health impact assessment. Black-Right-Pointing-Pointer Differences between the dynamic and residential exposure were quantified. Black-Right-Pointing-Pointer Modest differences in health impact were found at a regional level.

Droughts have been recorded all across Canada and have had significant impacts on individuals and communities. With climate change, projections suggest an increasing risk of drought in Canada, particularly in the south and interior. However, there has been little research on the impacts of drought on human health and the implications of a changing climate. A review of the Canadian, U.S. and international literature relevant to the Canadian context was conducted to better define these impacts and adaptations available to protect health. Drought can impact respiratory health, mental health, illnesses related to exposure to toxins, food/water security, rates of injury and infectious diseases (including food-, water- and vector-borne diseases). A range of direct and indirect adaptation (e.g., agricultural adaptation) options exist to cope with drought. Many have already been employed by public health officials, such as communicable disease monitoring and surveillance and public education and outreach. However, gaps exist in our understanding of the impacts of short-term vs. prolonged drought on the health of Canadians, projections of drought and its characteristics at the regional level and the effectiveness of current adaptations. Further research will be critical to inform adaptation planning to reduce future drought-related risks to health.

Background Although rabies represents an important public health threat, it is still a neglected disease in Asia and Africa where it causes tens of thousands of deaths annually despite available human and animal vaccines. In the Central African Republic (CAR), an endemic country for rabies, this disease remains poorly investigated. Methods To evaluate the extent of the threat that rabies poses in the CAR, we analyzed data for 2012 from the National Reference Laboratory for Rabies, where laboratory confirmation was performed by immunofluorescence and PCR for both animal and human suspected cases, and data from the only anti-rabies dispensary of the country and only place where post-exposure prophylaxis (PEP) is available. Both are located in Bangui, the capital of the CAR. For positive samples, a portion of the N gene was amplified and sequenced to determine the molecular epidemiology of circulating strains. Results In 2012, 966 exposed persons visited the anti-rabies dispensary and 632 received a post-exposure rabies vaccination. More than 90% of the exposed persons were from Bangui and its suburbs and almost 60% of them were under 15-years of age. No rabies-related human death was confirmed. Of the 82 samples from suspected rabid dogs tested, 69 were confirmed positive. Most of the rabid dogs were owned although unvaccinated. There was a strong spatiotemporal correlation within Bangui and within the country between reported human exposures and detection of rabid dogs (Pcanine rabies was endemic in the CAR in 2012 and had a detrimental impact on human health as shown by the hundreds of exposed persons who received PEP. Implementation of effective public health interventions including mass dog vaccination and improvement of the surveillance and the access to PEP are urgently needed in this country. PMID:26859829

Economic value of U.S. fossil fuel electricity health impacts.

Machol, Ben; Rizk, Sarah

2013-02-01

Fossil fuel energy has several externalities not accounted for in the retail price, including associated adverse human health impacts, future costs from climate change, and other environmental damages. Here, we quantify the economic value of health impacts associated with PM(2.5) and PM(2.5) precursors (NO(x) and SO(2)) on a per kilowatt hour basis. We provide figures based on state electricity profiles, national averages and fossil fuel type. We find that the economic value of improved human health associated with avoiding emissions from fossil fuel electricity in the United States ranges from a low of $0.005-$0.013/kWh in California to a high of $0.41-$1.01/kWh in Maryland. When accounting for the adverse health impacts of imported electricity, the California figure increases to $0.03-$0.07/kWh. Nationally, the average economic value of health impacts associated with fossil fuel usage is $0.14-$0.35/kWh. For coal, oil, and natural gas, respectively, associated economic values of health impacts are $0.19-$0.45/kWh, $0.08-$0.19/kWh, and $0.01-$0.02/kWh. For coal and oil, these costs are larger than the typical retail price of electricity, demonstrating the magnitude of the externality. When the economic value of health impacts resulting from air emissions is considered, our analysis suggests that on average, U.S. consumers of electricity should be willing to pay $0.24-$0.45/kWh for alternatives such as energy efficiency investments or emission-free renewable sources that avoid fossil fuel combustion. The economic value of health impacts is approximately an order of magnitude larger than estimates of the social cost of carbon for fossil fuel electricity. In total, we estimate that the economic value of health impacts from fossil fuel electricity in the United States is $361.7-886.5 billion annually, representing 2.5-6.0% of the national GDP.

2009-01-01

Pakistan's water crisis, especially serious water shortages have had a great impact on the health of the general population. Today majority of Pakistanis have no access to improved water sources which force people to consume polluted drinking water that results in the shape of waterborne diseases. In addition to this, household characteristics, includes mother's education and family income, also have an impact on drinking water quality and ultimately on human health. This study was conducted in three districts of Province Punjab both in urban and rural areas. The sample size of this study was 600 females of age group 20-60 years. From the data, it was concluded that mother's education and family income were affecting drinking water quality and human health. As the mother's years of education increased, the health issues decreased. Similarly, as the level of income increased, people suffered from water related diseases decreased. (author)

The impact of particulate matter (PM and nitric oxides (NOx on human health and an analysis of selected sources accounting for their emission in Poland

Directory of Open Access Journals (Sweden)

Jakub Krzeszowiak

2016-10-01

Full Text Available Introduction and objective: This paper is concerned with the harmful impact of nitric oxides (NOx and particulate matter (PM on humans. The objective was to determine which source of emission is the most urgent in terms of its reduction.Abbreviated description of the state of knowledge: In published epidemiological studies multiple notifications indicating the harmful impact of particulate matter on human health can be found. The harmful impact is underscored by the increase in the number of hospitalisations owing to diseases of respiratory and cardio-vascular systems, as well as by the rise in general fatality rate. The analysis of the PM impact on the human body is prompted by the fact that its detrimental effects are not clearly defined. Additionally, nitric oxides contribute to the increased number of exacerbations of respiratory disease and are a factor increasing susceptibility to development of local inflammation. Conclusions: The following study is meant to show that the air pollution which derives from vehicles (NOx and PM has a significant impact on human health. This applies particularly to residents of cities and big towns. This issue has gained special importance in Poland. According to the data from the Central Statistical Office, the increasing number of vehicles in use and their age lead to increased emission of the pollutants considered.

The human health impact of Nyiragongo and Nyamulagira eruptions on Goma city and its surrounding area

Located in the east of the Democratic Republic of Congo (DRC), Nyiragongo and Nyamulagira are two of the most active volcanoes in Africa. Nyiragongo last erupted in January 2002 and Nyamulagira in November 2011. Even if only a small number of victims resulted directly from these eruptions (notably because they both happened in the day-time), the town of Goma (approx. 700 000 inhabitants) is directly threatened by the fluid lava flows, of which the speed can reach several tens of km/h. But this is not the only menace. Indeed, Nyiragongo hosts a permanent lava lake that produces a plume of gases rich in sulphur (SO2), carbon (CO2), and halogen compounds (HCl, HF). As for Nyamulagira, it makes a major contribution to these emissions during its frequent and regular periods of eruptive activity (approx. every two years). Although the region under study is densely populated (up to 250 inh/km2), and basic volcanic hazard mapping exists, an updated and long-term evaluation of the specific impact of Nyiragongo and Nyamulagira semi-permanent volcanic plumes on the population health has not been done to date. It is the objective of this study. Michigan Technological University (MTU, USA) provides satellite data retrievals of volcanogenic SO2 gas columns. These remote sensing data provide insights about the spatial distribution of Nyiragongo and Nyamulagira plumes, which are used to select the sampling areas for studying the human health impact of volcanic emissions. Based on the Congolese Health Information System (HIS) data provided by the CEMUBAC, our study is focused on the 1999-2010 time period. Scientific studies carried out on other active volcanoes suggest that certain pathologies could be linked to a high concentration of SO2 in the atmosphere. These include Acute Respiratory Infections (ARI), conjunctivitis, skin diseases, and ear-nose-throat infections. Using Poisson regression analysis, we determine a Relative Risk Index (IRR) that allows us to identify the years

The impact of HIV/AIDS on human development in African countries.

Boutayeb, Abdesslam

2009-11-18

In the present paper, we consider the impact of HIV/AIDS on human development in African countries, showing that, beyond health issues, this disease should and must be seen as a global development concern, affecting all components of human development. Consequently, we stress the necessity of multidisciplinary approaches that model, estimate and predict the real impact of HIV/AIDS on human development of African countries in order to optimise the strategies proposed by national countries, international institutions and their partners. In our search strategy, we relied on secondary information, mainly through National Human Development Reports of some African countries and regular publications released by the United Nations (UN), United Nations Development Programme (UNDP), World Health Organization (WHO) and the World Bank. We restricted ourselves to reports dealing explicitly with the impact of HIV/AIDS on human development in African countries. HIV/AIDS is affecting the global human development of African countries through its devastating impact on health and demographic indicators such as life expectancy at birth, healthcare assistance, age and sex distribution, economic indicators like income, work force, and economic growth, education and knowledge acquisition and other indicators like governance, gender inequality and human rights. On the basis of the national reports reviewed, it appears clearly that HIV/AIDS is no longer a crisis only for the healthcare sector, but presents a challenge to all sectors. Consequently, HIV/AIDS is a development question and should be viewed as such. The disease is impeding development by imposing a steady decline in the key indicators of human development and hence reversing the social and economic gains that African countries are striving to attain. Being at the same time a cause and consequence of poverty and underdevelopment, it constitutes a challenge to human security and human development by diminishing the chances of

Organic food and the impact on human health.

In the last decade, the production and consumption of organic food have increased steadily worldwide, despite the lower productivity of organic crops. Indeed, the population attributes healthier properties to organic food. Although scientific evidence is still scarce, organic agriculture seems to contribute to maintaining an optimal health status and decreases the risk of developing chronic diseases. This may be due to the higher content of bioactive compounds and lower content of unhealthy substances such as cadmium and synthetic fertilizers and pesticides in organic foods of plant origin compared to conventional agricultural products. Thus, large long-term intervention studies are needed to determine whether an organic diet is healthier than a diet including conventionally grown food products. This review provides an update of the present knowledge of the impact of an organic versus a conventional food diet on health.

Health impact assessment: where does the law come in?

Hart, David Q.C.

2004-01-01

The European Convention on Human Rights has profound implications for HIA. Public authorities have a positive obligation to stop others from infringing citizens' rights to life and to respect for private and family life. These rights are qualified and have now been interpreted in many thousands of cases. Authorities must, as best they reasonably can, secure the safety of citizens and inform the citizens about the safety or otherwise of any development. Authorities have to strike a balance between the individuals rights and the public benefit. Any public authority before approving a scheme or reaching a regulatory decision which may impact on human rights must consider the nature of that impact, its seriousness and whether it can be justified on public interest grounds. A number of court judgements in cases concerning these issues are discussed. This article is not about how certain of the ideas underlying Health Impact Assessment, in certain circumstances, are or can be incorporated in existing legally recognised instruments such as Environmental Impact Assessments. Nor is it about the statutory powers which authorities--local and national--could, if so inclined, exercise, to further the health and well-being of their constituents. It is about something rather more general, important and yet rather formless, namely the duties identified by the European Court of Human Rights as resting upon public authorities to take steps to safeguard the public health rights of their citizens

The European Marine Board recently published a position paper on linking oceans and human health as a strategic research priority for Europe. With this position paper as a reference, the March 2014 Cornwall Oceans and Human Health Workshop brought together key scientists, policy makers, funders, business, and non governmental organisations from Europe and the US to review the recent interdisciplinary and cutting edge research in oceans and human health specifically the growing evidence of the impacts of oceans and seas on human health and wellbeing (and the effects of humans on the oceans). These impacts are a complex mixture of negative influences (e.g. from climate change and extreme weather to harmful algal blooms and chemical pollution) and beneficial factors (e.g. from natural products including seafood to marine renewable energy and wellbeing from interactions with coastal environments). Integrated approaches across disciplines, institutions, and nations in science and policy are needed to protect both the oceans and human health and wellbeing now and in the future.

Air pollution and its impact on human health in mega cities

International Nuclear Information System (INIS)

Ali, I.

1999-01-01

One of the major problems faced by the over crowded mega-cities of the world in general and that in third world is the alarming levels of air pollution causing damage to the health of its inhabitants. In Cairo estimated lives lost annually due to air pollution varies between 4000 to 16000 while Delhi has been rated as the most polluted city in the world. Karachi now a mega-city typically represents pollution status of the third world. Major cause of pollution is more than 0.62 millions vehicles on the roads. The pollution due to industries is localized and mainly affects the health of the workers. Measurement carried out for the selected areas along the roads carrying high density traffic show a very high pollution level (CO, 3 to 10 ppm; CO/sub 2/,170 to 350 ppm; HC 0.274 to 0.360 vol. %; particulate matter 67.0 to 565.5 ug/m/sup 3/. A parallel hospital survey to correlate air borne disease with air pollution indicates that over 16600 to 22977 patients suffered from air borne diseases while 6377 from bacterial infection. Analysis showed that 70% of the patients suffering from airborne disease come from the surveyed areas with high level pollution. Cancer is shifting from old age to middle age group indicating deteriorating air environment. Ratio of male to female patients is 2:1, which is indicative of hazardous ambient air quality outside to which men are exposed more than women. The paper discusses in depth the air pollution and its impact on human health in mega cities with Karachi as a case study. (author)

Previous studies often neglected the direct exposure to soil heavy metals in human health risk assessment. The purpose of this study was to assess the environmental impact and site-specific health risks of chromium (Cr) by both direct and indirect exposure assessment method. Results suggested that total Cr was shown a substantial buildup with a significant increase in the industrial and cultivated soils (averaged 1910 and 986 mg kg(-1), respectively). The Cr contents of vegetables exceeded the maximum permissible concentration by more than four times in every case. Human exposure to Cr was mainly due to dietary food intake in farming locations and due to soil ingestion in both industrial and residential sites. Soil ingestion was the main contributor pathway for direct exposure, followed by inhalation, and then dermal contact. The highest risks of vegetable ingestion were associated with consumption of Chinese cabbage. The results also indicated that plant tissues are able to convert the potentially toxic Cr (VI) species into the non-toxic Cr (III) species. The analyses of human health risks indicated that an important portion of the population is at risk, especially in the industrial site. Copyright © 2011 Elsevier B.V. All rights reserved.

Mind-body medicine: stress and its impact on overall health and longevity.

Vitetta, L; Anton, B; Cortizo, F; Sali, A

2005-12-01

The belief that adverse life stressors and the emotional states that can lead to major negative impacts on an individual's body functions and hence health has been held since antiquity. Adverse health outcomes such as coronary heart disease, gastrointestinal distress, and cancer have been linked to unresolved lifestyle stresses that can be expressed as a negative impact on human survival and ultimately a decrease of the human life span. Psychological modulation of immune function is now a well-established phenomenon, with much of the relevant literature published within the last 50 years. Psychoneuroimmunology and psychoneuroendocrinology embrace the scientific evidence of research of the mind with that of endocrinology, neurology and immunology, whereby the brain and body communicate with each other in a multidirectional flow of information that consists of hormones, neurotransmitters/neuropeptides, and cytokines. Advances in mind-body medicine research together with healthy nutrition and lifestyle choices can have a significant impact on health maintenance and disease prevention and hence the prolongation of the human life span.

The Elephant Vanishes: impact of human-elephant conflict on people's wellbeing.

2012-11-01

Human-wildlife conflicts impact upon the wellbeing of marginalised people, worldwide. Although tangible losses from such conflicts are well documented, hidden health consequences remain under-researched. Based on preliminary clinical ethnographic inquiries and sustained fieldwork in Assam, India, this paper documents mental health antecedents and consequences including severe untreated psychiatric morbidity and substance abuse. The case studies presented make visible the hidden mental health dimensions of human-elephant conflict. The paper illustrates how health impacts of conflicts penetrate far deeper than immediate physical threat from elephants, worsens pre-existing mental illness of marginalised people, and leads to newer psychiatric and social pathologies. These conflicts are enacted and perpetuated in institutional spaces of inequality. The authors argue that both wildlife conservation and community mental health disciplines would be enhanced by coordinated intervention. The paper concludes by generating questions that are fundamental for a new interdisciplinary paradigm that bridges ecology and the clinic. Crown Copyright © 2012. Published by Elsevier Ltd.

The transplantation of conventional human cell and tissue grafts, such as heart valve replacements and skin for severely burnt patients, has saved many lives over the last decades. The late eighties saw the emergence of tissue engineering with the focus on the development of biological substitutes that restore or improve tissue function. In the nineties, at the height of the tissue engineering hype, industry incited policymakers to create a European regulatory environment, which would facilitate the emergence of a strong single market for tissue engineered products and their starting materials (human cells and tissues). In this paper we analyze the elaboration process of this new European Union (EU) human cell and tissue product regulatory regime-i.e. the EU Cell and Tissue Directives (EUCTDs) and the Advanced Therapy Medicinal Product (ATMP) Regulation and evaluate its impact on Member States' health care systems. We demonstrate that the successful lobbying on key areas of regulatory and policy processes by industry, in congruence with Europe's risk aversion and urge to promote growth and jobs, led to excessively business oriented legislation. Expensive industry oriented requirements were introduced and contentious social and ethical issues were excluded. We found indications that this new EU safety and health legislation will adversely impact Member States' health care systems; since 30 December 2012 (the end of the ATMP transitional period) there is a clear threat to the sustainability of some lifesaving and established ATMPs that were provided by public health institutions and small and medium-sized enterprises under the frame of the EUCTDs. In the light of the current economic crisis it is not clear how social security systems will cope with the inflation of costs associated with this new regulatory regime and how priorities will be set with regard to reimbursement decisions. We argue that the ATMP Regulation should urgently be revised to focus on delivering

Overwhelming evidence has shown that, from the Industrial Revolution to the present, human activities influence ground-level ozone (O 3 ) concentrations. Past studies demonstrate links between O 3 exposure and health. However, knowledge gaps remain in our understanding concerning the impacts of climate change mitigation policies on O 3 concentrations and health. Using a hybrid downscaling approach, we evaluated the separate impact of climate change and emission control policies on O 3 levels and associated excess mortality in the US in the 2050s under two Representative Concentration Pathways (RCPs). We show that, by the 2050s, under RCP4.5, increased O 3 levels due to combined climate change and emission control policies, could contribute to an increase of approximately 50 premature deaths annually nationwide in the US. The biggest impact, however, is seen under RCP8.5, where rises in O 3 concentrations are expected to result in over 2,200 additional premature deaths annually. The largest increases in O 3 are seen in RCP8.5 in the Northeast, the Southeast, the Central, and the West regions of the US. Additionally, when O 3 increases are examined by climate change and emissions contributions separately, the benefits of emissions mitigation efforts may significantly outweigh the effects of climate change mitigation policies on O 3 -related mortality.

Globalization, human rights, and the social determinants of health.

2009-02-01

Globalization, a process characterized by the growing interdependence of the world's people, impacts health systems and the social determinants of health in ways that are detrimental to health equity. In a world in which there are few countervailing normative and policy approaches to the dominant neoliberal regime underpinning globalization, the human rights paradigm constitutes a widely shared foundation for challenging globalization's effects. The substantive rights enumerated in human rights instruments include the right to the highest attainable level of physical and mental health and others that are relevant to the determinants of health. The rights stipulated in these documents impose extensive legal obligations on states that have ratified these documents and confer health entitlements on their residents. Human rights norms have also inspired civil society efforts to improve access to essential medicines and medical services, particularly for HIV/AIDS. Nevertheless, many factors reduce the potential counterweight human rights might exert, including and specifically the nature of the human rights approach, weak political commitments to promoting and protecting health rights on the part of some states and their lack of institutional and economic resources to do so. Global economic markets and the relative power of global economic institutions are also shrinking national policy space. This article reviews the potential contributions and limitations of human rights to achieving greater equity in shaping the social determinants of health.

Climate change impacts on human exposures to air pollution ...

Science.gov (United States)

This is an abstract for a presentations at the Annual Conference of the International Society on Exposure Science and Environmental Epidemiology. This presentation will serve as an introduction to the symposium. As we consider the potential health impacts of a warming planet, the relationships between climate change and air pollutants become increasingly important to understand. These relationships are complex and highly variable, causing a variety of environmental impacts at local, regional and global scales. Human exposures and health impacts for air pollutants have the potential to be altered by changes in climate through multiple factors that drive population exposures to these pollutants. Research on this topic will provide both state and local governments with the tools and scientific knowledge base to undertake any necessary adaptation of the air pollution regulations and/or public health management systems in the face of climate change.

Space Radiation and Risks to Human Health

The radiation environment in space poses significant challenges to human health and is a major concern for long duration manned space missions. Outside the Earth's protective magnetosphere, astronauts are exposed to higher levels of galactic cosmic rays, whose physical characteristics are distinct from terrestrial sources of radiation such as x-rays and gamma-rays. Galactic cosmic rays consist of high energy and high mass nuclei as well as high energy protons; they impart unique biological damage as they traverse through tissue with impacts on human health that are largely unknown. The major health issues of concern are the risks of radiation carcinogenesis, acute and late decrements to the central nervous system, degenerative tissue effects such as cardiovascular disease, as well as possible acute radiation syndromes due to an unshielded exposure to a large solar particle event. The NASA Human Research Program's Space Radiation Program Element is focused on characterization and mitigation of these space radiation health risks along with understanding these risks in context of the other biological stressors found in the space environment. In this overview, we will provide a description of these health risks and the Element's research strategies to understand and mitigate these risks.

Human rights from the grassroots up: Vermont's campaign for universal health care.

Science.gov (United States)

McGill, Mariah

2012-06-15

In 2008, the Vermont Workers' Center launched the "Healthcare Is a Human Right Campaign," a grassroots campaign to secure the creation of a universal health care system in Vermont. Campaign organizers used a human rights framework to mobilize thousands of voters in support of universal health care. In response to this extraordinary grassroots effort, the state legislature passed health care legislation that incorporates human rights principles into Vermont law and provides a framework for universal health care. The United States has often lagged behind other nations in recognizing economic, social, and cultural (ESC) rights, including the right to health. Nonetheless, activists have begun to incorporate ESC rights into domestic advocacy campaigns, and state and local governments are beginning to respond where the federal government has not. Vermont serves as a powerful example of how a human rights framework can inform health care policy and inspire grassroots campaigns in the United States. This three-part article documents the Vermont Workers' Center campaign and discusses the impact that human rights activity at the grassroots level may have on attitudes towards ESC rights in the United States. The first part describes the Vermont health care crisis and explains why the center adopted international human rights principles for their campaign. The article then goes on to discuss the three-year campaign and analyze the health care reform bill that the Vermont legislature passed. Finally, the article discusses the campaign's local and national impact. Copyright © 2012 McGill.

for household size, the incidence of human illness increased 1.31-fold for every 10 cases of animal illness or death observed (95% CI 1.16–1.49). Access and utilization of animal source foods such as milk and eggs were positively associated with the number of cattle and chickens owned by the household. Additionally, health care seeking was correlated with household incomes and wealth, which were in turn correlated with livestock herd size. Conclusion This study platform provides a unique longitudinal dataset that allows for the determination and quantification of linkages between human and animal health, including the impact of healthy animals on human disease averted, malnutrition, household educational attainment, and income levels.

Full Text Available Although rabies represents an important public health threat, it is still a neglected disease in Asia and Africa where it causes tens of thousands of deaths annually despite available human and animal vaccines. In the Central African Republic (CAR, an endemic country for rabies, this disease remains poorly investigated.To evaluate the extent of the threat that rabies poses in the CAR, we analyzed data for 2012 from the National Reference Laboratory for Rabies, where laboratory confirmation was performed by immunofluorescence and PCR for both animal and human suspected cases, and data from the only anti-rabies dispensary of the country and only place where post-exposure prophylaxis (PEP is available. Both are located in Bangui, the capital of the CAR. For positive samples, a portion of the N gene was amplified and sequenced to determine the molecular epidemiology of circulating strains.In 2012, 966 exposed persons visited the anti-rabies dispensary and 632 received a post-exposure rabies vaccination. More than 90% of the exposed persons were from Bangui and its suburbs and almost 60% of them were under 15-years of age. No rabies-related human death was confirmed. Of the 82 samples from suspected rabid dogs tested, 69 were confirmed positive. Most of the rabid dogs were owned although unvaccinated. There was a strong spatiotemporal correlation within Bangui and within the country between reported human exposures and detection of rabid dogs (P<0.001. Phylogenetic analysis indicated that three variants belonging to Africa I and II lineages actively circulated in 2012.These data indicate that canine rabies was endemic in the CAR in 2012 and had a detrimental impact on human health as shown by the hundreds of exposed persons who received PEP. Implementation of effective public health interventions including mass dog vaccination and improvement of the surveillance and the access to PEP are urgently needed in this country.

Globally, much weight is currently being placed on agriculture to provide food for the growing population as well as feedstock for the bioenergy industry. Unfortunately, the intensification of agricultural operations to satisfy these growing needs has been associated with a number of environmental and human health risks. A review of publications on the subject was conducted and emphasis was placed on articles focusing on agriculture, environment, and public health as well as their interactions. Supporting information was also gathered from publications of various agricultural and environmental agencies. Agricultural practices with potential negative implications on the environment and human health were identified broadly as: (a) utilization of biosolids and animal manures, (b) use of agricultural chemicals, (c) management of post-harvest residue, (d) irrigation, and (e) tillage operations. Soil, water, and air contamination by nutrients, heavy metals, pathogens, and pesticides, as well as air contamination by particulate matters, noxious gases, and pathogens were among the leading environmental impacts. Some of the human-health impacts identified included neurological and reproductive defects, cardiovascular risks, cancers and other diseases (of kidney, liver, lung, and skin), skin allergies, gastroenteritis, and methemoglobinemia. Continual awareness on the impacts of the reviewed agricultural practices on environmental quality and human health and the implementation of experimentally-backed best management practices in agricultural systems remain indispensable.

What impact do Global Health Initiatives have on human resources for antiretroviral treatment roll-out? A qualitative policy analysis of implementation processes in Zambia

Directory of Open Access Journals (Sweden)

Hanefeld Johanna

2009-02-01

Full Text Available Abstract Background Since the beginning of the 21st century, development assistance for HIV/AIDS has increasingly been provided through Global Health Initiatives, specifically the United States Presidential Emergency Plan for AIDS Relief, the Global Fund to Fight HIV, TB and Malaria and the World Bank Multi-country AIDS Programme. Zambia, like many of the countries heavily affected by HIV/AIDS in southern Africa, also faces a shortage of human resources for health. The country receives significant amounts of funding from GHIs for the large-scale provision of antiretroviral treatment through the public and private sector. This paper examines the impact of GHIs on human resources for ART roll-out in Zambia, at national level, in one province and two districts. Methods It is a qualitative policy analysis relying on in-depth interviews with more than 90 policy-makers and implementers at all levels. Results Findings show that while GHIs do not provide significant funding for additional human resources, their interventions have significant impact on human resources for health at all levels. While GHIs successfully retrain a large number of health workers, evidence suggests that GHIs actively deplete the pool of skilled human resources for health by recruiting public sector staff to work for GHI-funded nongovernmental implementing agencies. The secondment of GHI staff into public sector facilities may help alleviate immediate staff shortages, but this practice risks undermining sustainability of programmes. GHI-supported programmes and initiatives add significantly to the workload of existing public sector staff at all levels, while incentives including salary top-ups and overtime payments mean that ART programmes are more popular among staff than services for non-focal diseases. Conclusion Research findings suggest that GHIs need to actively mediate against the potentially negative consequences of their funding on human resources for health. Evidence

Global health and economic impacts of future ozone pollution

2009-01-01

We assess the human health and economic impacts of projected 2000-2050 changes in ozone pollution using the MIT Emissions Prediction and Policy Analysis - Health Effects (EPPA-HE) model, in combination with results from the GEOS-Chem global tropospheric chemistry model of climate and chemistry effects of projected future emissions. We use EPPA-HE to assess the human health damages (including mortality and morbidity) caused by ozone pollution, and quantify their economic impacts in sixteen world regions. We compare the costs of ozone pollution under scenarios with 2000 and 2050 ozone precursor and greenhouse gas emissions (using the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A1B scenario). We estimate that health costs due to global ozone pollution above pre-industrial levels by 2050 will be $580 billion (year 2000$) and that mortalities from acute exposure will exceed 2 million. We find that previous methodologies underestimate costs of air pollution by more than a third because they do not take into account the long-term, compounding effects of health costs. The economic effects of emissions changes far exceed the influence of climate alone.

Evaluating Modeled Impact Metrics for Human Health, Agriculture Growth, and Near-Term Climate

Simulated metrics that assess impacts on human health, agriculture growth, and near-term climate were evaluated using ground-based and satellite observations. The NASA GISS ModelE2 and GEOS-Chem models were used to simulate the near-present chemistry of the atmosphere. A suite of simulations that varied by model, meteorology, horizontal resolution, emissions inventory, and emissions year were performed, enabling an analysis of metric sensitivities to various model components. All simulations utilized consistent anthropogenic global emissions inventories (ECLIPSE V5a or CEDS), and an evaluation of simulated results were carried out for 2004-2006 and 2009-2011 over the United States and 2014-2015 over China. Results for O3- and PM2.5-based metrics featured minor differences due to the model resolutions considered here (2.0° × 2.5° and 0.5° × 0.666°) and model, meteorology, and emissions inventory each played larger roles in variances. Surface metrics related to O3 were consistently high biased, though to varying degrees, demonstrating the need to evaluate particular modeling frameworks before O3 impacts are quantified. Surface metrics related to PM2.5 were diverse, indicating that a multimodel mean with robust results are valuable tools in predicting PM2.5-related impacts. Oftentimes, the configuration that captured the change of a metric best over time differed from the configuration that captured the magnitude of the same metric best, demonstrating the challenge in skillfully simulating impacts. These results highlight the strengths and weaknesses of these models in simulating impact metrics related to air quality and near-term climate. With such information, the reliability of historical and future simulations can be better understood.

Terroir as a Concept to Improve Human Health

Science.gov (United States)

Brevik, Eric C.; Steffan, Joshua J.; Burgess, Lynn C.; Cerdà, Artemi; Pereg, Lily

2017-04-01

Soil is important to human health because of the ability of healthy soils to supply nutrients through food products, medications derived from soil, its ability to clean water, and for many other positive reasons. On the other hand, degraded soils can have negative impacts on human health through processes such as dust generation and by acting as a point of human contact with heavy metals, organic chemicals, and pathogens. Despite the definite links between soil and human health, it is likely that most people don't think about soil when considering human health issues. In fact, there appears to be a disconnect between most people in our modern society and soil, and when people do notice soil it often seems to be in a negative context, leading to terms such as "soiled", "dirty", "dirt poor", etc. People pay attention to and care for things that matter to them, and creating a more positive public image of soil has the possibility of improving human health by leading to careful and caring treatment of the soil resource. The concept of terroir is a good example of a setting within which soils have a more positive image. While terroir originally established a connection between those who love wine and the soils that produce those wines, the concept has been expanded to many additional products such as cacao, cheese, coffee, fruits, olive oil, and vegetables. If the terroir concept could be expanded to include additional products that are important to people and expanded into parts of the world where it is not currently well known, that may provide an increased positive perception of soil, and thereby indirectly improve human health. It may even be possible to provide a terroir link to direct health benefits, such as medications derived from a given soil environment, and therefore provide a very focused emphasis on soil and human health issues. Therefore, we advocate a concerted effort to expand the terroir concept as a means to improve overall human health.

Changes in morbidity and mortality are interpreted as changes in labour productivity and demand for health care, and used to shock the GTAP-E computable general equilibrium model, calibrated for the year 2050. GDP, welfare and investment fall (rise) in regions with net negative (positive) health impacts. Prices, production, and terms of trade show a mixed pattern. Direct cost estimates, common in climate change impact studies, underestimate the true welfare losses. (author)

This paper will describe the impact on the human lung of haze from forest fires in Indonesia based on data collected from different provinces. Data were collected from personal reports from pulmonologists working in the area as well as from province/district health offices and hospitals. These data show that there was a significant impact of haze to the human lung. There was a significant increase in respiratory conditions, lung function complaints and other related impacts. Further studies, especially cohort studies, should be undertaken so that the long-term' impact of pollution from forest fires can be known.

Limiting the impact of light pollution on human health, environment and stellar visibility.

Light pollution is one of the most rapidly increasing types of environmental degradation. Its levels have been growing exponentially over the natural nocturnal lighting levels provided by starlight and moonlight. To limit this pollution several effective practices have been defined: the use of shielding on lighting fixture to prevent direct upward light, particularly at low angles above the horizon; no over lighting, i.e. avoid using higher lighting levels than strictly needed for the task, constraining illumination to the area where it is needed and the time it will be used. Nevertheless, even after the best control of the light distribution is reached and when the proper quantity of light is used, some upward light emission remains, due to reflections from the lit surfaces and atmospheric scatter. The environmental impact of this "residual light pollution", cannot be neglected and should be limited too. Here we propose a new way to limit the effects of this residual light pollution on wildlife, human health and stellar visibility. We performed analysis of the spectra of common types of lamps for external use, including the new LEDs. We evaluated their emissions relative to the spectral response functions of human eye photoreceptors, in the photopic, scotopic and the 'meltopic' melatonin suppressing bands. We found that the amount of pollution is strongly dependent on the spectral characteristics of the lamps, with the more environmentally friendly lamps being low pressure sodium, followed by high pressure sodium. Most polluting are the lamps with a strong blue emission, like Metal Halide and white LEDs. Migration from the now widely used sodium lamps to white lamps (MH and LEDs) would produce an increase of pollution in the scotopic and melatonin suppression bands of more than five times the present levels, supposing the same photopic installed flux. This increase will exacerbate known and possible unknown effects of light pollution on human health, environment

To address the need for timely and comprehensive human resources for health (HRH) information, governments and organizations have been actively investing in electronic health information interventions, including in low-resource settings. The economics of human resources information systems (HRISs) in low-resource settings are not well understood, however, and warrant investigation and validation. This case study describes Uganda's Human Resources for Health Information System (HRHIS), implemented with support from the US Agency for International Development, and documents perceptions of its impact on the health labour market against the backdrop of the costs of implementation. Through interviews with end users and implementers in six different settings, we document pre-implementation data challenges and consider how the HRHIS has been perceived to affect human resources decision-making and the healthcare employment environment. This multisite case study documented a range of perceived benefits of Uganda's HRHIS through interviews with end users that sought to capture the baseline (or pre-implementation) state of affairs, the perceived impact of the HRHIS and the monetary value associated with each benefit. In general, the system appears to be strengthening both demand for health workers (through improved awareness of staffing patterns) and supply (by improving licensing, recruitment and competency of the health workforce). This heightened ability to identify high-value employees makes the health sector more competitive for high-quality workers, and this elevation of the health workforce also has broader implications for health system performance and population health. Overall, it is clear that HRHIS end users in Uganda perceived the system to have significantly improved day-to-day operations as well as longer term institutional mandates. A more efficient and responsive approach to HRH allows the health sector to recruit the best candidates, train employees in

Impacts on human health from the coal and nuclear fuel cycles and other technologies associated with electric power generation and transmission

International Nuclear Information System (INIS)

Radford, E.P.

1980-01-01

Major public health impacts of electric power generation and transmission associated with the nuclear fuel cycle and with coal use are evaluated. Only existing technology is evaluated. The only health effects of concern are those leading to definable human disease and injury. Health effects are scaled to a nominal 1000 Megawatt (electric) plant fueled by either option. Comparison of the total health effects to the general public gives: nuclear, 0.03 to 0.05 major health effects per 1000 MWe per year; coal, 0.7 to 3.7 per 1000 MWe per year. Thus for the general public the health risks from the coal cycle are about 50 times greater than for the nuclear cycle. Health effects to workers in the industry are currently quite high. For the nuclear cycle, 4.6 to 5.1 major health impacts per 1000 MWe per year; for coal, 6.5 to 10.9. The two-fold greater risk for the coal cycle is primarily due to high injury rates in coal miners. There is no evidence that electrical transmission contributes any health effects to the general public, except for episodes where broken power lines come in contact with people. For power line workers, the risk is estimated at 0.1 serious injury per 1000 MWe per year

The health of populations depends on the availability of clean air, water, food, and sanitation, exposure to pathogens, toxins and environmental hazards, and numerous genetic, behavioral and social factors. For many thousands of years, human life expectancy was low, and population growth was slow. The development of technology-based civilizations facilitated what Abdel Omran called "epidemiological transition," with increasing life expectancy and rapid population growth. To a large extent, the spectacular growth of human populations during the past two centuries was made possible by the energy extracted from fossil fuels. We have now learned, however, that greenhouse gases from fossil fuel combustion are warming the planet's surface, causing changes in oceanic and atmospheric systems, and disrupting weather and hydrological patterns. Climate change poses unprecedented threats to human health by impacts on food and water security, heat waves and droughts, violent storms, infectious disease, and rising sea levels. Whether or not humanity can reduce greenhouse gas emissions quickly enough to slow climate change to a rate that will allow societies to successfully adapt is not yet known. This essay reviews the current state of relevant knowledge, and points in a few directions that those interested in human health may wish to consider. Copyright © 2014 Elsevier Inc.

Thirteen states in the United States allow the spreading of O&G wastewaters on roads for deicing or dust suppression. In this study, the potential environmental and human health impacts of this practice are evaluated. Analyses of O&G wastewaters spread on roads in the northeastern, U.S. show that these wastewaters have salt, radioactivity, and organic contaminant concentrations often many times above drinking water standards. Bioassays also indicated that these wastewaters contain organic micropollutants that affected signaling pathways consistent with xenobiotic metabolism and caused toxicity to aquatic organisms like Daphnia magna. The potential toxicity of these wastewaters is a concern as lab experiments demonstrated that nearly all of the metals from these wastewaters leach from roads after rain events, likely reaching ground and surface water. Release of a known carcinogen (e.g., radium) from roads treated with O&G wastewaters has been largely ignored. In Pennsylvania from 2008 to 2014, spreading O&G wastewater on roads released over 4 times more radium to the environment (320 millicuries) than O&G wastewater treatment facilities and 200 times more radium than spill events. Currently, state-by-state regulations do not require radium analyses prior to treating roads with O&G wastewaters. Methods for reducing the potential impacts of spreading O&G wastewaters on roads are discussed.

Kiribati—a low-lying, resource-poor Pacific atoll nation—is one of the most vulnerable countries in the World to the impacts of climate change, including the likely detrimental effects on human health. We describe the preparation of a climate change and health adaptation plan for Kiribati carried out by the World Health Organization and the Kiribati Ministry of Health and Medical Services, including an assessment of risks to health, sources of vulnerability and suggestions for highest priority adaptation responses. This paper identifies advantages and disadvantages in the process that was followed, lays out a future direction of climate change and health adaptation work in Kiribati, and proposes lessons that may be applicable to other small, developing island nations as they prepare for and adapt to the impacts of climate change on health.

If it is true that health is a priority objective of medicine, then medical practice can only be successful if the meaning of the term "health" is known. Various attempts have been made over the years to define health. This paper proposes a new definition. In addition to current health concepts, it also takes into account the distinction between specifically human (great) health and health as the absence of disease and illness-i.e. small health. The feeling of leading a life that makes sense plays a key role in determining specifically human great health.

The symposium explored the various techniques and methods available to study the potential effects that various energy-producing industries may have on human health. Three papers presented at Session I dealt with national energy needs, resources, and future developments; responsibilities and capabilities in ERDA as related to the health and environmental impacts of energy productions; and health hazards associated with alternate energy sources. Four papers presented at Session II reviewed standards setting for the worker and for the public; the radiation experience; and developing health policies and standards as the responsibility of the scientist. Eight papers in Sessions III and IV, Sources of Information, dealt with developing a health standard from epidemiological and clinical data and from laboratory animal data; carcinogenesis, mutagenesis, teratogenesis, and behavior changes as end points in health impact assessments; new methods and approaches to health impact assessment; problems in sampling for health impact; and the application of scientific data to worker/workplace health decision making. Two papers at Session V covered bases for the application of scientific data to health standards and health and environmental standards from a legal viewpoint. A final discussion, Room for Controversy, was conducted by four panelists. (MCW)

Recent clinical studies show that the contour of the photoplethysmogram (PPG) wave contains valuable information for characterizing cardiovascular activity. However, analyzing the PPG wave contour is difficult; therefore, researchers have applied first or higher order derivatives to emphasize and conveniently quantify subtle changes in the filtered PPG contour. Our hypothesis is that analyzing the whole PPG recording rather than each PPG wave contour or on a beat-by-beat basis can detect heat-stressed subjects and that, consequently, we will be able to investigate the impact of global warming on human health. Here, we explore the most suitable derivative order for heat stress assessment based on the energy and entropy of the whole PPG recording. The results of our study indicate that the use Int. J. Environ. Res. Public Health 2015, 7 12777 of the entropy of the seventh derivative of the filtered PPG signal shows promising results in detecting heat stress using 20-second recordings, with an overall accuracy of 71.6%. Moreover, the combination of the entropy of the seventh derivative of the filtered PPG signal with the root mean square of successive differences, or RMSSD (a traditional heart rate variability index of heat stress), improved the detection of heat stress to 88.9% accuracy.

Due to the build up of green house gases in atmosphere, less heat escapes through the atmosphere promoting global warming. This may result in world wide droughts, sea-level rise inundating islands and coastal countries, cataclysmic hurricanes etc. Human health as a result of these changes, will be affected both physiologically and psychologically. Physiological effects may be more pronounced in cases occurring due to changes in rainfall and temperature patterns, food production amounts, water availability, etc. Psychological impact may be more in cases of catastrophes like floods, hurricanes or famine. In this paper, an attempt has been made to highlight the implications of global warming on human health due to temperature change. Food production changes and ultra-violet radiation effects and cataclysmic disaster effects. (author)

Due to increasing population and per-capita water demand, demands for water are increasing in many parts of the world. Consequently, overuse of limited water resources leaves only small amounts of water in rivers and is bringing about rapid drawdown of groundwater tables. Water resources are affected by human activities such as excessive inputs of nutrients and other contaminants, agriculture and aquaculture expansions, and many development activities. The combined effects of modifying the water environments, both in terms of quantity and quality, on water supply and human health are presented in the paper with some examples from the Asian countries. In rural and sub-urban areas in Bangladesh and Vietnam, for example, the traditional way of obtaining surface water from ponds had been replaced by taking groundwaters to avert the microbial health risks that had arisen from contamination by human wastes. Such a change of water sources, however, has brought about human health impact caused by arsenic on a massive scale. In Thailand, the industrial development has driven the residents to get groundwater leaden with very high fluoride. Monitoring the urine fluoride levels reveal the risk of drinking fluoride-laden groundwaters. Rivers are also affected by extensive exploitation such as sand mining. As a result, turbidity changes abruptly after a heavy rainfall. In cities, due to shrinking water resources they have to take poor quality waters from contaminated sources. Algal blooms are seen in many reservoirs and lakes due to increasing levels of nutrients. Hence, it is likely that algal toxins may enter the water supply systems. Because most of the water treatment plants are not designed to remove those known and unknown contaminants, it is estimated that quite a large number of people are now under the threat of the public health "gtime bomb,"h which may one day bring about mass-scale health problems. In order to mitigate the negative impacts of modifying the water

2016-06-01

The incidence of human rights violations in mental health care across nations has been described as a "global emergency" and an "unresolved global crisis." The relationship between mental health and human rights is complex and bidirectional. Human rights violations can negatively impact mental health. Conversely, respecting human rights can improve mental health. This article reviews cases where an explicitly human rights-based approach was used in mental health care settings. Although the included studies did not exhibit a high level of methodological rigor, the qualitative information obtained was considered useful and informative for future studies. All studies reviewed suggest that human-rights based approaches can lead to clinical improvements at relatively low costs. Human rights-based approaches should be utilized for legal and moral reasons, since human rights are fundamental pillars of justice and civilization. The fact that such approaches can contribute to positive therapeutic outcomes and, potentially, cost savings, is additional reason for their implementation. However, the small sample size and lack of controlled, quantitative measures limit the strength of conclusions drawn from included studies. More objective, high quality research is needed to ascertain the true extent of benefits to service users and providers.

Climate change, aeroallergens, natural particulates, and human health in Australia: state of the science and policy.

Science.gov (United States)

Beggs, Paul John; Bennett, Charmian Margaret

2011-03-01

The objective of this article is to systematically review and assess what is known about the impacts of climate change on aeroallergens and other naturally derived particulates, and the associated human health impacts, and to examine responses to these in Australia, focusing on adaptation. Prior research was searched using several general and discipline-specific research databases. The review concludes that whereas there is little original research on the impacts of climate change on aeroallergens and other naturally derived particulates in Australia, or the human health consequences of these, research from overseas suggests that these impacts may be adverse and of considerable magnitude. More research is required to assess the impacts of climate change on these airborne particles and associated diseases in Australia and other parts of the Asia-Pacific. There are important policy implications of this review. There is a need for enhanced monitoring of the atmospheric environment and associated health conditions in Australia. Education about climate change and human health in general, and air quality and related diseases specifically, is required for the community, health professionals, and others. Improvements are needed in the preparedness of infrastructure, such as health care facilities and early warning systems, particularly for aeroallergens, and all of these adaptive policy responses require further research.

Marine mammals as sentinel species for oceans and human health.

Science.gov (United States)

Bossart, G D

2011-05-01

The long-term consequences of climate change and potential environmental degradation are likely to include aspects of disease emergence in marine plants and animals. In turn, these emerging diseases may have epizootic potential, zoonotic implications, and a complex pathogenesis involving other cofactors such as anthropogenic contaminant burden, genetics, and immunologic dysfunction. The concept of marine sentinel organisms provides one approach to evaluating aquatic ecosystem health. Such sentinels are barometers for current or potential negative impacts on individual- and population-level animal health. In turn, using marine sentinels permits better characterization and management of impacts that ultimately affect animal and human health associated with the oceans. Marine mammals are prime sentinel species because many species have long life spans, are long-term coastal residents, feed at a high trophic level, and have unique fat stores that can serve as depots for anthropogenic toxins. Marine mammals may be exposed to environmental stressors such as chemical pollutants, harmful algal biotoxins, and emerging or resurging pathogens. Since many marine mammal species share the coastal environment with humans and consume the same food, they also may serve as effective sentinels for public health problems. Finally, marine mammals are charismatic megafauna that typically stimulate an exaggerated human behavioral response and are thus more likely to be observed.

Dust, Climate, and Human Health

Maynard, Nancy G.

Air pollution from both natural and anthropogenic causes is considered to be one of the most serious world-wide environment-related health problems, and is expected to become worse with changes in the global climate. Dust storms from the atmospheric transport of desert soil dust that has been lifted and carried by the winds - often over significant distances - have become an increasingly important emerging air quality issue for many populations. Recent studies have shown that the dust storms can cause significant health impacts from the dust itself as well as the accompanying pollutants, pesticides, metals, salt, plant debris, and other inorganic and organic materials, including viable microorganisms (bacteria, viruses and fungi). For example, thousands of tons of Asian desert sediments, some containing pesticides and herbicides from farming regions, are commonly transported into the Arctic during dust storm events. These chemicals have been identified in animal and human tissues among Arctic indigenous populations. Millions of tons of airborne desert dust are being tracked by satellite imagery, which clearly shows the magnitude as well as the temporal and spatial variability of dust storms across the "dust belt" regions of North Africa, the Middle East, and China. This paper summarizes the most recent findings on the effects of airborne desert dust on human health as well as potential climate influences on dust and health.

Assessing the joint impact of DNAPL source-zone behavior and degradation products on the probabilistic characterization of human health risk

Henri, Christopher V.; Fernàndez-Garcia, Daniel; de Barros, Felipe P. J.

2016-02-01

The release of industrial contaminants into the subsurface has led to a rapid degradation of groundwater resources. Contamination caused by Dense Non-Aqueous Phase Liquids (DNAPLs) is particularly severe owing to their limited solubility, slow dissolution and in many cases high toxicity. A greater insight into how the DNAPL source zone behavior and the contaminant release towards the aquifer impact human health risk is crucial for an appropriate risk management. Risk analysis is further complicated by the uncertainty in aquifer properties and contaminant conditions. This study focuses on the impact of the DNAPL release mode on the human health risk propagation along the aquifer under uncertain conditions. Contaminant concentrations released from the source zone are described using a screening approach with a set of parameters representing several scenarios of DNAPL architecture. The uncertainty in the hydraulic properties is systematically accounted for by high-resolution Monte Carlo simulations. We simulate the release and the transport of the chlorinated solvent perchloroethylene and its carcinogenic degradation products in randomly heterogeneous porous media. The human health risk posed by the chemical mixture of these contaminants is characterized by the low-order statistics and the probability density function of common risk metrics. We show that the zone of high risk (hot spot) is independent of the DNAPL mass release mode, and that the risk amplitude is mostly controlled by heterogeneities and by the source zone architecture. The risk is lower and less uncertain when the source zone is formed mostly by ganglia than by pools. We also illustrate how the source zone efficiency (intensity of the water flux crossing the source zone) affects the risk posed by an exposure to the chemical mixture. Results display that high source zone efficiencies are counter-intuitively beneficial, decreasing the risk because of a reduction in the time available for the production

Health and equity impacts of climate change in Aotearoa-New Zealand, and health gains from climate action.

2014-11-28

Human-caused climate change poses an increasingly serious and urgent threat to health and health equity. Under all the climate projections reported in the recent Intergovernmental Panel on Climate Change assessment, New Zealand will experience direct impacts, biologically mediated impacts, and socially mediated impacts on health. These will disproportionately affect populations that already experience disadvantage and poorer health. Without rapid global action to reduce greenhouse gas emissions (particularly from fossil fuels), the world will breach its carbon budget and may experience high levels of warming (land temperatures on average 4-7 degrees Celsius higher by 2100). This level of climate change would threaten the habitability of some parts of the world because of extreme weather, limits on working outdoors, and severely reduced food production. However, well-planned action to reduce greenhouse gas emissions could bring about substantial benefits to health, and help New Zealand tackle its costly burden of health inequity and chronic disease.

Full Text Available The association between wind turbines and health effects is highly debated. Some argue that reported health effects are related to wind turbine operation (electromagnetic fields (EMF, shadow flicker, audible noise, low frequency noise, infrasound. Others suggest that when turbines are sited correctly, effects are more likely attributable to a number of subjective variables that result in an annoyed/stressed state. In this review we provide a bibliographic-like summary and analysis of the science around this issue specifically in terms of noise (including audible, low frequency noise and infrasound, EMF and shadow flicker. Now there are roughly 60 scientific peer-reviewed articles on this issue. The available scientific evidence suggests that EMF, shadow flicker, low frequency noise and infrasound from wind turbines are not likely to affect human health; some studies have found that audible noise from wind turbines can be annoying to some. Annoyance may be associated with some self-reported health effects (e.g., sleep disturbance especially at sound pressure levels >40 dB(A. Because environmental noise above certain levels is a recognized factor in a number of health issues, siting restrictions have been implemented in many jurisdictions to limit noise exposure. These setbacks should help alleviate annoyance from noise. Subjective variables (attitudes and expectations are also linked to annoyance and have the potential to facilitate other health complaints via the nocebo effect. Therefore, it is possible that a segment of the population may remain annoyed (or report other health impacts even when noise limits are enforced. Based on the findings and scientific merit of the available studies, the weight of evidence suggests that when sited properly, wind turbines are not related to adverse health. Stemming from this review, we provide a number of recommended best practices for wind turbine development in the context of human health.

A review of the health impacts of barium from natural and anthropogenic exposure.

2014-08-01

There is an increasing public awareness of the relatively new and expanded industrial barium uses which are potential sources of human exposure (e.g., a shale gas development that causes an increased awareness of environmental exposures to barium). However, absorption of barium in exposed humans and a full spectrum of its health effects, especially among chronically exposed to moderate and low doses of barium populations, remain unclear. We suggest a systematic literature review (from 1875 to 2014) on environmental distribution of barium, its bioaccumulation, and potential and proven health impacts (in animal models and humans) to provide the information that can be used for optimization of future experimental and epidemiological studies and developing of mitigative and preventive strategies to minimize negative health effects in exposed populations. The potential health effects of barium exposure are largely based on animal studies, while epidemiological data for humans, specifically for chronic low-level exposures, are sparse. The reported health effects include cardiovascular and kidney diseases, metabolic, neurological, and mental disorders. Age, race, dietary patterns, behavioral risks (e.g., smoking), use of medications (those that interfere with absorbed barium in human organism), and specific physiological status (e.g., pregnancy) can modify barium effects on human health. Identifying, evaluating, and predicting the health effects of chronic low-level and moderate-level barium exposures in humans is challenging: Future research is needed to develop an understanding of barium bioaccumulation in order to mitigate its potential health impacts in various exposured populations. Further, while occupationally exposed at-risk populations exist, it is also important to identify potentially vulnerable subgroups among non-occupationally exposed populations (e.g., elderly, pregnant women, children) who are at higher risk of barium exposure from drinking water and food.

Vanessa Cruz Santos

2013-12-01

Full Text Available Abortion in Brazil provides public health impacts, mainly due to the high rate of maternal morbidity and mortality, because it most often occurs in an illegal practice and / or unsafe, because of the illegality of abortion in certain situations in the country. Therefore, it is an issue that refers to the various reflections, such as legal, moral, cultural, socio-economic and bioethical. Given the above, the study aims to address about abortion in Brazil and the impacts of illegality in public health. Study of literature review, descriptive and discursive, held in the database SciELO sites and governmental and non-governmental organizations. It was evident that the illegality of abortion in Brazil is harmful to the health of women who resort to unsafe practices and / or illegal, a violation of human rights, the women’s autonomy, as well as providing public health impacts, and sometimes this actually happens because the deficit in quality of care, specifically to sexual and reproductive health, as the actions of Family Planning. It is considered that the way of abortion in Brazil requires modifications, especially with regard to legislative and bioethics conflicts.

Although several major health effects of ultraviolet radiation (UVR) are established, precise quantification of this effect is difficult. New Zealand has the most southerly located major human population in the world, and has a particular contribution to make to worldwide progress. However, current information on the frequency of the relevant health problems is unsatisfactory. Major developments in research in New Zealand are needed. UVR is an established causal factor for malignant melanoma, other types of skin cancer, cataracts and some other eye problems and has been implicated in some immunological effects. (author). 5 refs

Measuring the Distributional Impact of Public Health Spending on Poverty in Nigeria

Directory of Open Access Journals (Sweden)

Olawale Ibrahim Olateju

2009-05-01

Full Text Available Most African health systems are replicas of what was inherited from the colonial era and are therefore unevenly weighted toward privileged elites and Urban centers. Improved health status leads to increased productivity, educational performance, higher life expectancy, savings and investments, and decreased debts and expenditure on health care. Ultimately this would lead to greater equity, economic return, and social and political stability. The health impacts of climate change can occur through a number of direct and indirect causal pathways, and the severity is in part determined by the adaptive capacity of the population. Those groups particularly at risk include poorer countries and communities, those geographically vulnerable to extreme weather events, and those highly dependent on agriculture for their livelihood.The paper examines the impact of public health expenditure, and poverty among the general populace. The trend of the country human development index and public expenditure on health were analyzed using correlation coefficient and regression analysis and simple descriptive analysis. The findings reveal that the variations in the human development index could be traced to the budget estimates

Aerosols can have significant influence on surface radiation, and the intense surface ultraviolet radiation Australia experiences contributes to Australia's high incidence rates for related human diseases. Aerosol properties, such as total column aerosol optical depth, have been measured over several years for varying lengths of time at sites across Australia using sunphotometers. Statistical analysis of the average daily aerosol optical depth over sites near Alice Springs, Canberra, Darwin, and Perth provides one measure of the annual atmospheric loading of aerosols over these sites. The sunphotometers used at these sites do not make measurements in the UV-B spectral region and have only one channel in the UV-A spectral region, the regions of most interest for assessing human health impact. Consequently, model calculations using standard aerosol types have been used to make an initial estimate of the impact of the aerosols found over these four sites on surface ultraviolet radiation. The aerosol loading is at times sufficient to significantly reduce the surface ultraviolet radiation, but few such days occur each year. The annual average effect of aerosols on surface ultraviolet radiation, thus, appears to be small compared to lifestyle factors, such as clothing and use of sunscreen.

In 31 August 2016, Brazilian president Dilma Rousseff was impeached and replaced by her vice president Michel Temer. Herein, we examine how the conservative agenda of Mr Temer and his supporters is influencing key decisions in the human rights and public health arena in Brazil. The government's austerity agenda includes severe cuts in critical areas such as health, education and science, jeopardising well-known strategies such as the Brazilian Public Health System (SUS) and nationwide cash transfer program, 'Bolsa Familia' - both benefited millions and were the largest of their kind in the world. Mr Temer's decisions show not only severe cuts in critical areas but also a political agenda that clearly demonstrates a broad shift away from the progressivism and social agenda presented and supported by its predecessors. Most vulnerable groups such as the LGBTQ community, women, people who use drugs and disenfranchised communities have been severely affected. Mr Temer's administration is putting Brazil far from its once nationwide goal to foster free and universal health care access and social equity for all its citizens. The near future for Brazil is unknown, but both national and international communities anticipate severe problems within the national human rights arena, if nothing changes.

Constant exposure to radio frequency signals from mobile phones and their base stations could adversely affect on human health. As a consequence, as a result of this impact it is appeared frequent headaches, loss of memory and concentration, tension in the eardrum and sudden bouts of fatigue, childhood leukemia, brain tumors, eye cataracts, cardiovascular diseases, disorders of the nervous system. Some people suffer from hyperelectrosensitivity. It should be noted that the analog phones much more harmful to human health than digital ones. Radio frequency of electromagnetic fields which is used by a modern cellular communications is in the range from 450 MHz to 1.9 GHz. Such fields unlike to ionizing radiation can not cause secondary radioactivity in the body. The cell phone is a device having a potential danger to health, so it is advisable wherever possible to protect yourselves from its use, or at least to minimize its use

Significant areas of the Brazilian Amazon have been deforested over the past few decades, with fire being the dominant method through which forests and vegetation are cleared. Fires emit large quantities of particulate matter into the atmosphere, degrading air quality and negatively impacting human health. Since 2004, Brazil has achieved substantial reductions in deforestation rates and associated deforestation fires. Here we assess the impact of this reduction on air quality and human health. We show that dry season (August - October) aerosol optical depth (AOD) retrieved by satellite over southwest Brazil and Bolivia is positively related to Brazil's annual deforestation rate (r=0.96, Pannually across South America. Future increases in Brazil's deforestation rates and associated fires may threaten the improved air quality reported here.

Early steps in the emergence of the discipline of "Oceans and Human Health" are charted in the USA and discussed in relation to past and present marine environment and human health research activities in Europe. Differences in terminology are considered, as well as differences in circumstances related to the various seas of Europe and the intensity of human coastal activity and impact. Opportunities to progress interdisciplinary research are described, and the value of horizon scanning for the early identification of emerging issues is highlighted. The challenges facing researchers and policymakers addressing oceans and human health issues are outlined and some suggestions offered regarding how further progress in research and training into both the risks and benefits of Oceans and Human Health might be made on both sides of the Atlantic.

Integrating human health into prospective impact assessments is known to be challenging. This is true for both approaches: dedicated health impact assessments (HIA) as well as inclusion of health into more general impact assessments. Acknowledging the full range of participatory, qualitative, and quantitative approaches, this study focuses on the latter, especially on computational tools for quantitative health modelling. We conducted a survey among tool developers concerning the status quo of development and availability of such tools; experiences made with model usage in real-life situations; and priorities for further development. Responding toolmaker groups described 17 such tools, most of them being maintained and reported as ready for use and covering a wide range of topics, including risk & protective factors, exposures, policies, and health outcomes. In recent years, existing models have been improved and were applied in new ways, and completely new models emerged. There was high agreement among respondents on the need to further develop methods for assessment of inequalities and uncertainty. The contribution of quantitative modeling to health foresight would benefit from building joint strategies of further tool development, improving the visibility of quantitative tools and methods, and engaging continuously with actual and potential users. - Highlights: • A survey investigated computational tools for health impact quantification. • Formal evaluation of such tools has been rare. • Handling inequalities and uncertainties are priority areas for further development. • Health foresight would benefit from tool developers and users forming a community. • Joint development strategies across computational tools are needed.

The impact of globalization on public health: implications for the UK Faculty of Public Health Medicine.

Lee, K

2000-09-01

There has been substantial discussion of globalization in the scholarly and popular press yet limited attention so far among public health professionals. This is so despite the many potential impacts of globalization on public health. Defining public health broadly, as focused on the collective health of populations requiring a range of intersectoral activities, globalization can be seen to have particular relevance. Globalization, in turn, can be defined as a process that is changing the nature of human interaction across a wide range of spheres and along at least three dimensions. Understanding public health and globalization in these ways suggests the urgent need for research to better understand the linkages between the two, and effective policy responses by a range of public health institutions, including the UK Faculty of Public Health Medicine. The paper is based on a review of secondary literature on globalization that led to the development of a conceptual framework for understanding potential impacts on the determinants of health and public health. The paper then discusses major areas of public health in relation to these potential impacts. It concludes with recommendations on how the UK Faculty of Public Health Medicine might contribute to addressing these impacts through its various activities. Although there is growing attention to the importance of globalization to public health, there has been limited research and policy development in the United Kingdom. The UK Faculty of Public Health Medicine needs to play an active role in bringing relevant issues to the attention of policy makers, and encourage its members to take up research, teaching and policy initiatives. The potential impacts of globalization support a broader understanding and practice of public health that embraces a wide range of health determinants.

The exposome is the totality of human environmental exposures from conception onwards. Identifying the contribution of the exposome to human diseases and health is a key issue in health research. Examples include the effect of air pollution exposure on cardiovascular diseases, the impact of disease vectors (mosquitos) and surface hydrology exposure on malaria, and the effect of fast food restaurant exposure on obesity. Essential to health research is to disentangle the effects of the exposome and genome on health. Ultimately this requires quantifying the totality of all human exposures, for each individual in the studied human population. This poses a massive challenge to geoscientists, as environmental data are required at a high spatial and temporal resolution, with a large spatial and temporal coverage representing the area inhabited by the population studied and the time span representing several decades. Then, these data need to be combined with space-time paths of individuals to calculate personal exposures for each individual in the population. The Global and Geo Health Data Centre is taking this challenge by providing a web service capable of enriching population data with exposome information. Our web service can generate environmental information either from archived national (up to 5 m spatial and 1 h temporal resolution) and global environmental information or generated on the fly using environmental models running as microservices. On top of these environmental data services runs an individual exposure service enabling health researchers to select different spatial and temporal aggregation methods and to upload space-time paths of individuals. These are then enriched with personal exposures and eventually returned to the user. We illustrate the service in an example of individual exposures to air pollutants calculated from hyper resolution air pollution data and various approaches to estimate space-time paths of individuals.

Comparative environmental and human health evaluations of thermolysis and solvolysis recycling technologies of carbon fiber reinforced polymer waste.

Science.gov (United States)

Khalil, Y F

2018-06-01

This quantitative research aims to compare environmental and human health impacts associated with two recycling technologies of CFRP waste. The 'baseline' recycling technology is the conventional thermolysis process via pyrolysis and the 'alternative' recycling technology is an emerging chemical treatment via solvolysis using supercritical water (SCW) to digest the thermoset matrix. Two Gate-to-Gate recycling models are developed using GaBi LCA platform. The selected functional unit (FU) is 1 kg CFRP waste and the geographical boundary of this comparative LCIA is defined to be within the U.S. The results of this comparative assessment brought to light new insights about the environmental and human health impacts of CFRP waste recycling via solvolysis using SCW and, therefore, helped close a gap in the current state of knowledge about sustainability of SCW-based solvolysis as compared to pyrolysis. Two research questions are posed to identify whether solvolysis recycling offers more environmental and human health gains relative to the conventional pyrolysis recycling. These research questions lay the basis for formulating two null hypotheses (H 0,1 and H 0,2 ) and their associated research hypotheses (H 1,1 and H 1,2 ). LCIA results interpretation included 'base case' scenarios, 'sensitivity studies,' and 'scenarios analysis.' The results revealed that: (a) recycling via solvolysis using SCW exhibits no gains in environmental and human health impacts relative to those impacts associated with recycling via pyrolysis and (b) use of natural gas in lieu of electricity for pyrolyzer's heating reduces the environmental and human health impacts by 37% (lowest) and up to 95.7% (highest). It is recommended that on-going experimental efforts that focus only on identifying the best solvent for solvolysis-based recycling should also consider quantification of the energy intensity as well as environmental and human health impacts of the proposed solvents.

We developed regionalized characterization factors (CFs) for human health damage from particulate matter (PM2.5) and ozone, and for damage to vegetation from ozone, at the global scale. These factors can be used in the impact assessment phase of an environmental life cycle assessment. CFs express the overall damage of a certain pollutant per unit of emission of a precursor, i.e. primary PM2.5, nitrogen oxides (NOx), ammonia (NH3), sulfur dioxide (SO2) and non-methane volatile organic compounds (NMVOCs). The global chemical transport model TM5 was used to calculate intake fractions of PM2.5 and ozone for 56 world regions covering the whole globe. Furthermore, region-specific effect and damage factors were derived, using mortality rates, background concentrations and years of life lost. The emission-weighted world average CF for primary PM2.5 emissions is 629 yr kton-1, varying up to 3 orders of magnitude over the regions. Larger CFs were obtained for emissions in central Asia and Europe, and smaller factors in Australia and South America. The world average CFs for PM2.5 from secondary aerosols, i.e. NOx, NH3, and SO2, is 67.2 to 183.4 yr kton-1. We found that the CFs for ozone human health damage are 2-4 orders of magnitude lower compared to the CFs for damage due to primary PM2.5 and PM2.5 precursor emissions. Human health damage due to the priority air pollutants considered in this study was 1.7·10-2 yr capita-1 worldwide in year 2010, with primary PM2.5 emissions as the main contributor (62%). The emission-weighted world average CF for ecosystem damage due to ozone was 2.5 km2 yr kton-1 for NMVOCs and 8.7 m2 yr kg-1 for NOx emissions, varying 2-3 orders of magnitude over the regions. Ecosystem damage due to the priority air pollutants considered in this study was 1.6·10-4 km2 capita-1 worldwide in 2010, with NOx as the main contributor (72%). The spatial range in CFs stresses the importance of including spatial variation in life cycle impact assessment of

Health is a focus reflecting the combined impacts of climate change on the physical environment, ecosystems, the economic environment and society. Long-term changes in the world's climate may affect many requisites of good health - sufficient food, safe and adequate drinking water and secure dwelling. The current large-scale social and environmental changes mean that we must assign a much higher priority to population health in the policy debate on climate change. Climate change will affect human health and wellbeing through a variety of mechanisms. Climate change can adversely impact on the availability of fresh water supply and the efficiency of local sewerage systems. It is also likely to affect food security. Cereal yields are expected to increase at high and mid latitudes but decrease at lower latitudes. Changes in food production are likely to significantly affect health in Africa. In addition, the distribution and seasonal transmission of several vector-borne infectious diseases (such as malaria and dengue) may be affected by climate change. Altered distribution of some vector species may be among the early signals of climate change. A change in the world climate could increase the frequency and severity of extreme weather events. The impacts on health of natural disasters are considerable - the number of people killed, injured or made homeless from such causes is increasingly alarming. The vulnerability of people living in risk-prone areas is an important contributor to disaster casualties and damage. An increase in heatwaves (and possibly air pollution) will be a problem in urban areas, where excess mortality and morbidity is currently observed during hot weather episodes. We can assume that climate change will affect the most vulnerable in developing countries. These might be socio-economic deprived populations, people who lack access to a health care system, technology and communication, as well as immuno compromised persons. The health community

Impacts on human health from the coal and nuclear fuel cycles and other technologies associated with electric power generation and transmission

International Nuclear Information System (INIS)

Radford, E.P.

1980-07-01

The report evaluates major public health impacts of electric power generation and transmission associated with the nuclear fuel cycle and with coal use. Only existing technology is evaluated. For the nuclear cycle, effects of future use of fuel reprocessing and long-term radioactive waste disposal are briefly considered. The health effects of concern are those leading to definable human disease and injury. Health effects are scaled to numbers of persons and activities associated with a nominal 1000-megawatt electric plant fueled by either option. Comparison of the total health effects to the general public shows that the health risks from the coal cycle are about 50 times greater than for the nuclear cycle (coal, 0.7-3.7 major health effects per 1000 MWe per year; nuclear, 0.03-0.05 per 1000 MWe per year). For workers, these rates are higher. No evidence is found that electrical transmission contributes any health effects to the general public, except when broken power lines come in contact with people

What Constitutes Evidence in Human Rights-Based Approaches to Health? Learning from Lived Experiences of Maternal and Sexual Reproductive Health.

Science.gov (United States)

Unnithan, Maya

2015-12-10

The impact of human rights interventions on health outcomes is complex, multiple, and difficult to ascertain in the conventional sense of cause and effect. Existing approaches based on probable (experimental and statistical) conclusions from evidence are limited in their ability to capture the impact of rights-based transformations in health. This paper argues that a focus on plausible conclusions from evidence enables policy makers and researchers to take into account the effects of a co-occurrence of multiple factors connected with human rights, including the significant role of "context" and power. Drawing on a subject-near and interpretive (in other words, with regard to meaning) perspective that focuses on the lived experiences of human rights-based interventions, the paper suggests that policy makers and researchers are best served by evidence arrived at through plausible, observational modes of ascertaining impact. Through an examination of what human rights-based interventions mean, based on the experience of their operationalization on the ground in culturally specific maternal and reproductive health care contexts, this paper contributes to an emerging scholarship that seeks to pluralize the concept of evidence and to address the methodological challenges posed by heterogeneous forms of evidence in the context of human rights as applied to health.

Industrial societies have altered the earth`s environment in ways that could have important, long-term ecological, economic, and health implications. In this paper the authors define, characterize, and evaluate parameter and outcome uncertainties using a model that links global climate change with predictions of chemical exposure and human health risk in the western region of the US. They illustrate the impact of uncertainty about global climate change on such potential secondary outcomes using as a case study the public health consequences related to the behavior environmentally of hexachlorobenzene (HCB), an ubiquitous multimedia pollutant. They begin by constructing a matrix that reveals the linkage between global environmental change and potential regional human-health effects that might be induced directly and/or indirectly by HCB released into the air and water. This matrix is useful for translating critical uncertainties into terms that can be understood and used by policy makers to formulate strategies against potential adverse irreversible health and economic consequences. Specifically, the authors employ a combined uncertainty/sensitivity analysis to investigate how the HCB that has been released is affected by increasing atmospheric temperature and the accompanying climate alterations that are anticipated and how such uncertainty propagates to affect the expected magnitude and calculational precision of estimates of associated potential human exposures and health effects.

This op-ed essay urges medical anthropologists to join a growing number of public health scholars to examine the impact of global warming on health. Adopting a critical medical anthropology perspective, I argue that global warming is yet another manifestation of the contradictions of the capitalist world system. Ultimately, an serious effort to mitigate the impact of global warming not only on health but also settlement patterns and subsistence will require the creation of a new global political economy based upon social parity, democratic processes, and environmental sustainability.

Dietary Vitamin C in Human Health.

Science.gov (United States)

Granger, Matthew; Eck, Peter

Vitamin C is essential to prevent scurvy in humans and is implicated in the primary prevention of common and complex diseases such as coronary heart disease, stroke, and cancer. This chapter reviews the latest knowledge about dietary vitamin C in human health with an emphasis on studies of the molecular mechanisms of vitamin C maintenance as well as gene-nutrient interactions modifying these relationships. Epidemiological evidence indicates 5% prevalence for vitamin C deficiency and 13% prevalence for suboptimal status even in industrialized countries. The daily intake (dose) and the corresponding systemic concentrations (response) are related in a saturable relationship, and low systemic vitamin C concentrations in observational studies are associated with negative health outcomes. However, there is no evidence that vitamin C supplementation impacts the risks for all-cause mortality, impaired cognitive performance, reduced quality of life, the development of eye diseases, infections, cardiovascular disease, and cancers. This might be related to the fact that prevention would not be realized by supplementation in populations already adequately supplied through dietary sources. Recent genetic association studies indicate that the dietary intake might not be the sole determinant of systemic concentrations, since variations in genes participating in redox homeostasis and vitamin C transport had been associated with lowered plasma concentrations. However, impact sizes are generally low and these phenomena might only affect individual of suboptimal dietary supply. © 2018 Elsevier Inc. All rights reserved.

Climate change affects human health in various ways. Health planners and policy makers are increasingly addressing potential health impacts of climate change. Ethiopia is vulnerable to these impacts. Assessing students' knowledge, understanding and perception about the health impact of climate change may promote educational endeavors to increase awareness of health impacts linked to climate change and to facilitate interventions. A cross-sectional study using a questionnaire was carried out among the health science students at Haramaya University. Quantitative methods were used to analyze the results. Over three quarters of the students were aware of health consequences of climate change, with slightly higher rates in females than males and a range from 60.7% (pharmacy students) to 100% (environmental health and post-graduate public health students). Electronic mass media was reportedly the major source of information but almost all (87.7%) students stated that their knowledge was insufficient to fully understand the public health impacts of climate change. Students who knew about climate change were more likely to perceive it as a serious health threat than those who were unaware of these impacts [OR: 17.8, 95% CI: 8.8-32.1] and also considered their departments to be concerned about climate change (OR: 7.3, 95% CI: 2.8-18.8), a perception that was also significantly more common among students who obtained their information from the electronic mass media and schools (p health impacts of climate change.

Anthropogenic climate change will affect global food production, with uncertain consequences for human health in developed countries. We investigated the potential impact of climate change on food security (nutrition and food safety) and the implications for human health in developed countries. Expert input and structured literature searches were conducted and synthesized to produce overall assessments of the likely impacts of climate change on global food production and recommendations for future research and policy changes. Increasing food prices may lower the nutritional quality of dietary intakes, exacerbate obesity, and amplify health inequalities. Altered conditions for food production may result in emerging pathogens, new crop and livestock species, and altered use of pesticides and veterinary medicines, and affect the main transfer mechanisms through which contaminants move from the environment into food. All these have implications for food safety and the nutritional content of food. Climate change mitigation may increase consumption of foods whose production reduces greenhouse gas emissions. Impacts may include reduced red meat consumption (with positive effects on saturated fat, but negative impacts on zinc and iron intake) and reduced winter fruit and vegetable consumption. Developed countries have complex structures in place that may be used to adapt to the food safety consequences of climate change, although their effectiveness will vary between countries, and the ability to respond to nutritional challenges is less certain. Climate change will have notable impacts upon nutrition and food safety in developed countries, but further research is necessary to accurately quantify these impacts. Uncertainty about future impacts, coupled with evidence that climate change may lead to more variable food quality, emphasizes the need to maintain and strengthen existing structures and policies to regulate food production, monitor food quality and safety, and

Multifaceted health impacts of Particulate Matter (PM and its management: An overview

Prabhat Kumar Rai

2015-03-01

Full Text Available Urban air quality is becoming a serious public health concern at global scale. Particulate matter (PM pollution is intimately linked with human health. Present review describes the different human health implications associated with PM pollution. PM may derive its origin from natural and anthropogenic sources. Vehicle derived pollutants as well as industrial emissions simultaneously release deleterious fine-grained PM into the atmosphere. Fine PM especially PM2.5 and PM10 are particularly deleterious to human health. Air pollution PM is an important environmental health risk factor for several respiratory and cardiovascular morbidity and mortality. Further, PM is inextricably linked with genotoxicity and mutations. Literature review of the cellular and molecular basis of adverse effects associated with PM is presented in this paper. Finally, management, existing technologies and policy options to reduce or mitigate the adverse health impacts of PM pollution is discussed as an eco-sustainable approach.

The impact of climate change through global warming has been a concern for some time now. Targets are being set for ratifying countries to reduce their CO{sup 2} emissions. In order to achieve reduction in CO{sup 2} emissions, there must be sustained move in the production of electricity from renewable sources other than fossil fuel combustion. Of the renewable energy sources, the most realistic and economic is Wind Power. The Asian continent is developing into one of the main powerhouses of Wind Energy. The strongest market leader in Wind Energy in the continent is India. On the flip side, there are some effects of Wind Turbines which are hazardous to human health like noise generated. Such hazards are also likely and known to affect the migratory birds during transition. This paper will address the effects of Wind Turbine on Human Health and Environment. The paper will focus on the following questions: (1)What are the potential health and environmental impacts of Wind Turbines? (2)How is exposure to Wind Turbine Noise assessed? (3)What consultation process with the community is required before Wind Farms are constructed? (Author)

Observed and projected impacts of climate change on marine fisheries, aquaculture, coastal tourism, and human health: an update

Directory of Open Access Journals (Sweden)

2016-04-01

Full Text Available The Intergovernmental Panel on Climate Change (IPCC Fifth Assessment Report (AR5 states that climate change and ocean acidification are altering the oceans at a rate that is unprecedented compared with the recent past, leading to multifaceted impacts on marine ecosystems, associated goods and services, and human societies. AR5 underlined key uncertainties that remain regarding how synergistic changes in the ocean are likely to affect human systems, and how humans are likely to respond to these events. As climate change research has accelerated rapidly following AR5, an updated synthesis of available knowledge is necessary to identify emerging evidence, and to thereby better inform policy discussions. This paper reviews the literature to capture corroborating, conflicting, and novel findings published following the cut-off date for contribution to AR5. Specifically, we highlight key scientific developments on the impacts of climate-induced changes in the ocean on key socioeconomic sectors, including fisheries, aquaculture and tourism. New evidence continues to support a climate-induced redistribution of benefits and losses at multiple scales and across coastal and marine socio-ecological systems, partly resulting from species and ecosystem range shifts and changes in primary productivity. New efforts have been made to characterize and value ecosystem services in the context of climate change, with specific relevance to ecosystem-based adaptation. Recent studies have also explored synergistic interactions between climatic drivers, and have found strong variability between impacts on species at different life stages. Although climate change may improve conditions for some types of freshwater aquaculture, potentially providing alternative opportunities to adapt to impacts on wild capture fisheries, ocean acidification poses a risk to shellfish fisheries and aquaculture. The risk of increased prevalence of disease under warmer temperatures is

Objective: To review the developments in human factors (HF) research on the challenges of health information technology (HIT) implementation and impact given the continuing incidence of usability problems and unintended consequences from HIT development and use. Methods: A search of PubMed/Medline and Web of Science® identified HF research published in 2015 and 2016. Electronic health records (EHRs) and patient-centred HIT emerged as significant foci of recent HF research. The authors selected prominent papers highlighting ongoing HF and usability challenges in these areas. This selective rather than systematic review of recent HF research highlights these key challenges and reflects on their implications on the future impact of HF research on HIT. Results: Research provides evidence of continued poor design, implementation, and usability of HIT, as well as technology-induced errors and unintended consequences. The paper highlights support for: (i) strengthening the evidence base on the benefits of HF approaches; (ii) improving knowledge translation in the implementation of HF approaches during HIT design, implementation, and evaluation; (iii) increasing transparency, governance, and enforcement of HF best practices at all stages of the HIT system development life cycle. Discussion and Conclusion: HF and usability approaches are yet to become embedded as integral components of HIT development, implementation, and impact assessment. As HIT becomes ever-more pervasive including with patients as end-users, there is a need to expand our conceptualisation of the problems to be addressed and the suite of tactics and strategies to be used to calibrate our pro-active involvement in its improvement.

Human trafficking is an increasingly well-recognized human rights violation that is estimated to involve more than 2 million victims worldwide each year. The health consequences of this issue bring victims into contact with health systems and healthcare providers, thus providing the potential for identification and intervention. A robust healthcare response, however, requires a healthcare workforce that is aware of the health impact of this issue; educated about how to identify and treat affected individuals in a compassionate, culturally aware, and trauma-informed manner; and trained about how to collaborate efficiently with law enforcement, case management, and advocacy partners. This article describes existing educational offerings about human trafficking designed for a healthcare audience and makes recommendations for further curriculum development. A keyword search and structured analysis of peer-reviewed and gray literature, conducted in 2011 and 2012, yielded 27 items that provide basic guidance to health professionals on human trafficking. The 27 resources differed substantially in format, length, scope, and intended audience. Topic areas covered by these resources included trafficking definitions and scope, health consequences, victim identification, appropriate treatment, referral to services, legal issues, and security. None of the educational resources has been rigorously evaluated. There is a clear need to develop, implement, and evaluate high-quality education and training programs that focus on human trafficking for healthcare providers.

Assessing the health workforce implications of health policy and programming: how a review of grey literature informed the development of a new impact assessment tool.

Science.gov (United States)

Nove, Andrea; Cometto, Giorgio; Campbell, James

2017-11-09

In their adoption of WHA resolution 69.19, World Health Organization Member States requested all bilateral and multilateral initiatives to conduct impact assessments of their funding to human resources for health. The High-Level Commission for Health Employment and Economic Growth similarly proposed that official development assistance for health, education, employment and gender are best aligned to creating decent jobs in the health and social workforce. No standard tools exist for assessing the impact of global health initiatives on the health workforce, but tools exist from other fields. The objectives of this paper are to describe how a review of grey literature informed the development of a draft health workforce impact assessment tool and to introduce the tool. A search of grey literature yielded 72 examples of impact assessment tools and guidance from a wide variety of fields including gender, health and human rights. These examples were reviewed, and information relevant to the development of a health workforce impact assessment was extracted from them using an inductive process. A number of good practice principles were identified from the review. These informed the development of a draft health workforce impact assessment tool, based on an established health labour market framework. The tool is designed to be applied before implementation. It consists of a relatively short and focused screening module to be applied to all relevant initiatives, followed by a more in-depth assessment to be applied only to initiatives for which the screening module indicates that significant implications for HRH are anticipated. It thus aims to strike a balance between maximising rigour and minimising administrative burden. The application of the new tool will help to ensure that health workforce implications are incorporated into global health decision-making processes from the outset and to enhance positive HRH impacts and avoid, minimise or offset negative impacts.

2009-01-01

The operation of a public port facility near Uranium City, Saskatchewan has resulted in elevated levels of hydrocarbons in soil, groundwater and sediment. Remedial action in the uplands portion of the site was successful and a risk management approach was initiated for the aquatic portion of the site in order to resolve human health and ecological issues. Ecological risks were assessed using a sediment weight-of-evidence approach involving chemistry, toxicity, bioaccumulation and benthic community structure. Human health risks were assessed via fish consumption, water ingestion and direct contact according to Health Canada guidance. This presentation included an overview of the general risk assessment approach as well as site-specific data and findings. The primary focus was on the challenges confronted during the risk assessment process, such as the need to include alkylated PAHs as a COPC in the human health risk assessment and to evaluate ongoing propeller wash and sediment resuspension for sediment risk management, even though the facility is no longer operational.

Wildfire smoke exposure and human health: Significant gaps in research for a growing public health issue.

Black, Carolyn; Tesfaigzi, Yohannes; Bassein, Jed A; Miller, Lisa A

2017-10-01

Understanding the effect of wildfire smoke exposure on human health represents a unique interdisciplinary challenge to the scientific community. Population health studies indicate that wildfire smoke is a risk to human health and increases the healthcare burden of smoke-impacted areas. However, wildfire smoke composition is complex and dynamic, making characterization and modeling difficult. Furthermore, current efforts to study the effect of wildfire smoke are limited by availability of air quality measures and inconsistent air quality reporting among researchers. To help address these issues, we conducted a substantive review of wildfire smoke effects on population health, wildfire smoke exposure in occupational health, and experimental wood smoke exposure. Our goal was to evaluate the current literature on wildfire smoke and highlight important gaps in research. In particular we emphasize long-term health effects of wildfire smoke, recovery following wildfire smoke exposure, and health consequences of exposure in children. Copyright © 2017 Elsevier B.V.

The interface of mental health and human rights in Indigenous peoples: triple jeopardy and triple opportunity.

Science.gov (United States)

Tarantola, Daniel

2007-01-01

Insufficient understanding of the reciprocal interactions between health and human rights, mental health and human rights and the realization of all human rights by Indigenous peoples constitute a triple jeopardy in how these topics are currently being addressed and/or openly antagonized. This paper will attempt to show how a combined health and human rights approach to mental health in Indigenous peoples can transform a triple jeopardy into a triple opportunity. The vast and growing body of literature on mental health, health as a whole, and human rights as these relate to health and to Indigenous peoples will be used to frame the discussion. Attention to the complex interactions of health and human rights can guide policy formulation and action by offering a method of analysis, a process of participatory decision and a framework for accountability. In addition, mental health can find its rightful place in the health and human rights discourse through efforts to help policymakers and practitioners broaden their vision of mental illness to holistically encompass aspects of physical, social, emotional and cultural wellbeing. Finally, connecting the role that rights realization plays in determining health and wellbeing will add power to the rightful claims by Indigenous peoples to the promotion and protection of all their human rights--civil, political, economic, social and cultural. Broadening the research agenda by applying systematically a health and human rights analytical framework to the understanding of social determinants of health would minimize the risk of assigning health outcome merely to behaviours, practices and lifestyles, uncovering structural determinants of holistic health entrenched in policies and governmental conduct. Building the evidence of the negative impact of human rights violation on health and the negative impact of ill-health on the fulfilment of other human rights can help in designing comprehensive interventions, building on the

A Contribution of Beef to Human Health: A Review of the Role of the Animal Production Systems

Full Text Available Meat and meat products constitute important source of protein, fat, and several functional compounds. Although beef consumption may implicate possible negative impacts on human health, its consumption can also contribute to human health. Quality traits of beef, as well as its nutritional properties, depend on animal genetics, feeding, livestock practices, and post mortem procedures. Available data show that emerging beef production systems are able to improve both, quality and nutritional traits of beef in a sustainable way. In this context, Argentina’s actions are aimed at maximising beef beneficial effects and minimising its negative impact on human health, in a way of contributing to global food security.

The objective of this evaluation is to understand the human health impacts of mountaintop removal (MTR) mining, the major method of coal mining in and around Central Appalachia. MTR mining impacts the air, water, and soil and raises concerns about potential adverse health effects in neighboring communities; exposures associated with MTR mining include particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), metals, hydrogen sulfide, and other recognized harmful substances. A systematic review was conducted of published studies of MTR mining and community health, occupational studies of MTR mining, and any available animal and in vitro experimental studies investigating the effects of exposures to MTR-mining-related chemical mixtures. Six databases (Embase, PsycINFO, PubMed, Scopus, Toxline, and Web of Science) were searched with customized terms, and no restrictions on publication year or language, through October 27, 2016. The eligibility criteria included all human population studies and animal models of human health, direct and indirect measures of MTR-mining exposure, any health-related effect or change in physiological response, and any study design type. Risk of bias was assessed for observational and experimental studies using an approach developed by the National Toxicology Program (NTP) Office of Health Assessment and Translation (OHAT). To provide context for these health effects, a summary of the exposure literature is included that focuses on describing findings for outdoor air, indoor air, and drinking water. From a literature search capturing 3088 studies, 33 human studies (29 community, four occupational), four experimental studies (two in rat, one in vitro and in mice, one in C. elegans), and 58 MTR mining exposure studies were identified. A number of health findings were reported in observational human studies, including cardiopulmonary effects, mortality, and birth defects. However, concerns for risk of bias were identified, especially

An explosive growth in natural gas production within the last decade has fueled concern over the public health impacts of air pollutant emissions from oil and gas sites in the Barnett and Eagle Ford shale regions of Texas. Commonly acknowledged sources of uncertainty are the lack of sustained monitoring of ambient concentrations of pollutants associated with gas mining, poor quantification of their emissions, and inability to correlate health symptoms with specific emission events. These uncertainties are best addressed not by conventional monitoring and modeling technology, but by increasingly available advanced techniques for real-time mobile monitoring, microscale modeling and source attribution, and real-time broadcasting of air quality and human health data over the World Wide Web. The combination of contemporary scientific and social media approaches can be used to develop a strategy to detect and quantify emission events from oil and gas facilities, alert nearby residents of these events, and collect associated human health data, all in real time or near-real time. The various technical elements of this strategy are demonstrated based on the results of past, current, and planned future monitoring studies in the Barnett and Eagle Ford shale regions. Resources should not be invested in expanding the conventional air quality monitoring network in the vicinity of oil and gas exploration and production sites. Rather, more contemporary monitoring and data analysis techniques should take the place of older methods to better protect the health of nearby residents and maintain the integrity of the surrounding environment.

Institutionalizing policy-level health impact assessment in Europe: is coupling health impact assessment with strategic environmental assessment the next step forward?

Science.gov (United States)

Wright, John; Parry, Jayne; Scully, Edward

2005-06-01

European Union (EU) Member States are interested in using health impact assessment (HIA) as a means of safeguarding their obligations to protect human health under the 1997 Treaty of Amsterdam. However, several have encountered difficulties institutionalizing HIA with the policy-making process. As a consequence, the World Health Organization (WHO) Regional Office for Europe has suggested coupling HIA with strategic environmental assessment (SEA). Traditionally, the incorporation of HIA into other forms of impact assessment has been resisted, for fear of losing its focus on health issues to environmental concerns, and compromising its social model of health with the introduction of biophysical indicators. But can these fears be substantiated? In this paper, we investigate the grounds for such concerns by reviewing the relevant policy documents and departmental guidelines of four non-European countries that have considered the use of integrated assessment. We found that the case for associating HIA with SEA in Europe is strong, and offers potential solutions to problems of screening, theoretical framework, causal pathways and ready entry to the policy process. Coupling HIA with SEA may thus be the next step forward in a longer journey towards institutionalizing HIA as an independent policy-linked device.

2012-10-15

Floods are the most common type of disaster globally, responsible for almost 53,000 deaths in the last decade alone (23:1 low- versus high-income countries). This review assessed recent epidemiological evidence on the impacts of floods on human health. Published articles (2004-2011) on the quantitative relationship between floods and health were systematically reviewed. 35 relevant epidemiological studies were identified. Health outcomes were categorized into short- and long-term and were found to depend on the flood characteristics and people's vulnerability. It was found that long-term health effects are currently not well understood. Mortality rates were found to increase by up to 50% in the first year post-flood. After floods, it was found there is an increased risk of disease outbreaks such as hepatitis E, gastrointestinal disease and leptospirosis, particularly in areas with poor hygiene and displaced populations. Psychological distress in survivors (prevalence 8.6% to 53% two years post-flood) can also exacerbate their physical illness. There is a need for effective policies to reduce and prevent flood-related morbidity and mortality. Such steps are contingent upon the improved understanding of potential health impacts of floods. Global trends in urbanization, burden of disease, malnutrition and maternal and child health must be better reflected in flood preparedness and mitigation programs. Crown Copyright © 2012.

A Review of the Impact of the Human Rights in Healthcare Programme in England and Wales.

Science.gov (United States)

Dyer, Lindsey

2015-12-10

This article provides the background to an analysis of the Human Rights in Healthcare Programme in England and Wales. Using evidence from source materials, summary publications, and official reports, it charts a small but important change in the relationship between health and human rights and shows how a small number of National Health Service organizations used a human rights-based approach (HRBA) to develop resources aimed at improving the quality of health services and health outcomes. Through a case study of one participating organization, it examines the development of approaches to measuring the outcomes and impacts of HRBAs. The article argues that because of the way the Programme was set up, it is not likely to provide the level of evidence of impact required to bring about a profound change in the relationship between human rights and health care. There is a need for a different approach that considers the big human rights questions that need to be asked. Copyright © 2015 Dyer.

2008-06-01

Genetically modified (or GM) plants have attracted a large amount of media attention in recent years and continue to do so. Despite this, the general public remains largely unaware of what a GM plant actually is or what advantages and disadvantages the technology has to offer, particularly with regard to the range of applications for which they can be used. From the first generation of GM crops, two main areas of concern have emerged, namely risk to the environment and risk to human health. As GM plants are gradually being introduced into the European Union there is likely to be increasing public concern regarding potential health issues. Although it is now commonplace for the press to adopt 'health campaigns', the information they publish is often unreliable and unrepresentative of the available scientific evidence. We consider it important that the medical profession should be aware of the state of the art, and, as they are often the first port of call for a concerned patient, be in a position to provide an informed opinion. This review will examine how GM plants may impact on human health both directly - through applications targeted at nutrition and enhancement of recombinant medicine production - but also indirectly, through potential effects on the environment. Finally, it will examine the most important opposition currently facing the worldwide adoption of this technology: public opinion.

Electronic cigarettes: human health effects.

Science.gov (United States)

Callahan-Lyon, Priscilla

2014-05-01

With the rapid increase in use of electronic nicotine delivery systems (ENDS), such as electronic cigarettes (e-cigarettes), users and non-users are exposed to the aerosol and product constituents. This is a review of published data on the human health effects of exposure to e-cigarettes and their components. Literature searches were conducted through September 2013 using multiple electronic databases. Forty-four articles are included in this analysis. E-cigarette aerosols may contain propylene glycol, glycerol, flavourings, other chemicals and, usually, nicotine. Aerosolised propylene glycol and glycerol produce mouth and throat irritation and dry cough. No data on the effects of flavouring inhalation were identified. Data on short-term health effects are limited and there are no adequate data on long-term effects. Aerosol exposure may be associated with respiratory function impairment, and serum cotinine levels are similar to those in traditional cigarette smokers. The high nicotine concentrations of some products increase exposure risks for non-users, particularly children. The dangers of secondhand and thirdhand aerosol exposure have not been thoroughly evaluated. Scientific evidence regarding the human health effects of e-cigarettes is limited. While e-cigarette aerosol may contain fewer toxicants than cigarette smoke, studies evaluating whether e-cigarettes are less harmful than cigarettes are inconclusive. Some evidence suggests that e-cigarette use may facilitate smoking cessation, but definitive data are lacking. No e-cigarette has been approved by FDA as a cessation aid. Environmental concerns and issues regarding non-user exposure exist. The health impact of e-cigarettes, for users and the public, cannot be determined with currently available data.

The impact of climate change has been significant enough to endanger human health both directly and indirectly via heat stress, degraded air quality, rising sea levels, food and water security, extreme weather events (e.g., floods, droughts, earthquakes, volcano eruptions, tsunamis, hurricanes, etc.), vulnerable shelter, and population migration. The deterioration of environmental conditions may facilitate the transmission of diarrhea, vector-borne and infectious diseases, cardiovascular and respiratory illnesses, malnutrition, etc. Indirect effects of climate change such as mental health problems due to stress, loss of homes, economic instability, and forced migration are also unignorably important. Children, the elderly, and communities living in poverty are among the most vulnerable of the harmful effects due to climate change. In this article, we have reviewed the scientific evidence for the human health impact of climate change and analyzed the various diseases in association with changes in the atmospheric environment and climate conditions.

Evidence of Human Health Impacts from Uncontrolled Coal Fires in Jharia, India

Dhar, U.; Balogun, A. H.; Finkelman, R.; Chakraborty, S.; Olanipekun, O.; Shaikh, W. A.

2017-12-01

Uncontrolled coal fires and burning coal waste piles have been reported from dozens of countries. These fires can be caused by spontaneous combustion, sparks from machinery, lightning strikes, grass or forest fires, or intentionally. Both underground and surface coal fires mobilize potentially toxic elements such as sulfur, arsenic, selenium, fluorine, lead, and mercury as well as dangerous organic compounds such as benzene, toluene, xylene, ethylbenzene and deadly gases such as CO2 and CO. Despite the serious health problems that can be caused by uncontrolled coal fires it is rather surprising that there has been so little research and documentation of their health impacts. Underground coal fires in the Jharia region of India where more than a million people reside, have been burning for 100 years. Numerous villages exist above the underground fires exposing the residents daily to dangerous emissions. Local residents near the fire affected areas do their daily chores without concern about the intensity of nearby fires. During winter children enjoy the heat of the coal fires oblivious to the potentially harmful emissions. To determine if these uncontrolled coal fires have caused health problems we developed a brief questionnaire on general health indices and administered it to residents of the Jharia region. Sixty responses were obtained from residents of two villages, one proximal to the coal fires and one about 5 miles away from the fires. The responses were statistically analyzed using SAS 9.4. It was observed that at a significance level of 5%, villagers who lived more than 5 miles away from the fires had a 98.3% decreased odds of having undesirable health outcomes. This brief survey indicates the risk posed by underground coal fires and how it contributes to the undesirable health impacts. What remains is to determine the specific health issues, what components of the emissions cause the health problems, and what can be done to minimize these problems

Integrating Environmental and Human Health Databases in the Great Lakes Basin: Themes, Challenges and Future Directions

2015-03-01

Full Text Available Many government, academic and research institutions collect environmental data that are relevant to understanding the relationship between environmental exposures and human health. Integrating these data with health outcome data presents new challenges that are important to consider to improve our effective use of environmental health information. Our objective was to identify the common themes related to the integration of environmental and health data, and suggest ways to address the challenges and make progress toward more effective use of data already collected, to further our understanding of environmental health associations in the Great Lakes region. Environmental and human health databases were identified and reviewed using literature searches and a series of one-on-one and group expert consultations. Databases identified were predominantly environmental stressors databases, with fewer found for health outcomes and human exposure. Nine themes or factors that impact integration were identified: data availability, accessibility, harmonization, stakeholder collaboration, policy and strategic alignment, resource adequacy, environmental health indicators, and data exchange networks. The use and cost effectiveness of data currently collected could be improved by strategic changes to data collection and access systems to provide better opportunities to identify and study environmental exposures that may impact human health.

DARTAB: a program to combine airborne radionuclide environmental exposure data with dosimetric and health effects data to generate tabulations of predicted health impacts

The DARTAB computer code combines radionuclide environmental exposure data with dosimetric and health effects data to generate tabulations of the predicted impact of radioactive airborne effluents. DARTAB is independent of the environmental transport code used to generate the environmental exposure data and the codes used to produce the dosimetric and health effects data. Therefore human dose and risk calculations need not be added to every environmental transport code. Options are included in DARTAB to permit the user to request tabulations by various topics (e.g., cancer site, exposure pathway, etc.) to facilitate characterization of the human health impacts of the effluents. The DARTAB code was written at ORNL for the US Environmental Protection Agency, Office of Radiation Programs

Chlorinated volatile organic compounds (Cl-VOCs) in environment - sources, potential human health impacts, and current remediation technologies.

Huang, Binbin; Lei, Chao; Wei, Chaohai; Zeng, Guangming

2014-10-01

Chlorinated volatile organic compounds (Cl-VOCs), including polychloromethanes, polychloroethanes and polychloroethylenes, are widely used as solvents, degreasing agents and a variety of commercial products. These compounds belong to a group of ubiquitous contaminants that can be found in contaminated soil, air and any kind of fluvial mediums such as groundwater, rivers and lakes. This review presents a summary of the research concerning the production levels and sources of Cl-VOCs, their potential impacts on human health as well as state-of-the-art remediation technologies. Important sources of Cl-VOCs principally include the emissions from industrial processes, the consumption of Cl-VOC-containing products, the disinfection process, as well as improper storage and disposal methods. Human exposure to Cl-VOCs can occur through different routes, including ingestion, inhalation and dermal contact. The toxicological impacts of these compounds have been carefully assessed, and the results demonstrate the potential associations of cancer incidence with exposure to Cl-VOCs. Most Cl-VOCs thus have been listed as priority pollutants by the Ministry of Environmental Protection (MEP) of China, Environmental Protection Agency of the U.S. (U.S. EPA) and European Commission (EC), and are under close monitor and strict control. Yet, more efforts will be put into the epidemiological studies for the risk of human exposure to Cl-VOCs and the exposure level measurements in contaminated sites in the future. State-of-the-art remediation technologies for Cl-VOCs employ non-destructive methods and destructive methods (e.g. thermal incineration, phytoremediation, biodegradation, advanced oxidation processes (AOPs) and reductive dechlorination), whose advantages, drawbacks and future developments are thoroughly discussed in the later sections.

Impact of UV Radiation on Genome Stability and Human Health.

Roy, Sujit

2017-01-01

Gradual depletion of the atmospheric ozone layer during the past few years has increased the incidence of solar UV radiation specifically the UV-C on earth's surface is one of the major environmental concerns because of the harmful effects of this radiation in all forms of life. The solar UV radiation including the harmful wavelength range of UV-B (280-320 nm) represents a significant climatic stress for both animals and plants, causing damage to the fundamental biomolecules such as DNA, proteins and lipids, thus activating genotoxic stress and induces genome instability. When DNA absorbs UV-B light, energy from the photon causes covalent linkages to form between adjacent pyrimidine bases, creating photoproducts, primarily cyclobutane pyrimidine dimers (CPDs) and pyrimidine-6,4-pyrimidinone photoproduct (6,4PPs). Pyrimidine dimers create distortions in the DNA strands and therefore can inhibit DNA replication as well transcription. Lack of efficient repair of UV-induced DNA damage may induce the formation of DNA double stand breaks (DSBs), one of the serious forms of damage in DNA double helix, as well as oxidative damage. Unrepaired DSBs in the actively dividing somatic cells severely affect cell growth and development, finally results in loss of cell viability and development of various diseases, such as cancer in man.This chapter mainly highlights the incidence of solar UV-radiation on earth's surface along with the formation of major types of UV-induced DNA damage and the associated repair mechanisms as well as methods of detecting DNA damage and finally our present understanding on the impact on solar UV radiation on human health.

Ongoing research to develop digestion-resistant starch for human health promotion integrates the disciplines of starch chemistry, agronomy, analytical chemistry, food science, nutrition, pathology, and microbiology. The objectives of this research include identifying components of starch structure that confer digestion resistance, developing novel plants and starches, and modifying foods to incorporate these starches. Furthermore, recent and ongoing studies address the impact of digestion-resistant starches on the prevention and control of chronic human diseases, including diabetes, colon cancer, and obesity. This review provides a transdisciplinary overview of this field, including a description of types of resistant starches; factors in plants that affect digestion resistance; methods for starch analysis; challenges in developing food products with resistant starches; mammalian intestinal and gut bacterial metabolism; potential effects on gut microbiota; and impacts and mechanisms for the prevention and control of colon cancer, diabetes, and obesity. Although this has been an active area of research and considerable progress has been made, many questions regarding how to best use digestion-resistant starches in human diets for disease prevention must be answered before the full potential of resistant starches can be realized.

Air pollution has become one of the major risks to human health because of the progressive increase in the use of vehicles powered by fossil fuels. Although lots of works on the health impact of ambient air pollution have been done in China, the following recommendations for future research were identified in this chapter: (1) the synergistic effect of indoor air pollution with climate change; (2) develop new technologies to improve accurate assessment of air pollution exposure; (3) well-designed cohort study of sensitive populations including children, older people, and people with chronic health problems; (4) multi-omics technologies in the underlying mechanisms study; and (5) benefits evaluation of improvement of air quality. In conclusion, China is becoming a suitable study site, providing an ideal opportunity to evaluate the effects of environmental pollution, including air pollution, on human health, which might serve as an example for developing countries where health impacts of air pollution are as serious as in China.

Full Text Available Of the most central elements of religions and most important issues in theology and the Contemporary study of religion is the category of faith and its greatest impact on various aspects of life. Faith, in Islamic and Christian theology, has common and also distinct aspects. The truth of Faith in Islamic thought was multidimensional and consists of a wide range of Confession of language, intellectual knowledge, heart affirmation and inner experience to the treatment involves external actions. In Christianity, it was faith in confirmation of the revealed proposition that led to a sense of transcendence and meta-proposition and created Interest mode in human And sometimes faith apply to the experience of presence and manifestation of God in life. The position of consensus and association between Islam and Christianity was consists of the doctrine of Belief in God and the prophecy and resurrection. This belief is based on the functionalist view affected on body and psyche (or soul health of the human. The impact of Faith on physical and mental health has been separately approved by the specialists. The impacts of faith and religious teachings on physical health have been investigated through psycho-neuro-physiological way that Faith and Religious teachings produce positive emotions in human. The emotions through autonomous nervous system strengthen the immune system and its optimal performance in a way that the messenger molecule called neuropeptide Y, carry the messages related to thoughts and transport it through the blood circulation, and the mental state directly relate to the body's cells. This is the most important factor in strengthening or weakening the immune system influenced by the thoughts and beliefs. Moreover, Te'osumatic medicine known as the God-body medicine, after the psychosomatic or psycho-body medicine confirms the impact of faith on the health and recovery of individuals.

According to a wide variety of analyses and projections, the potential effects of global climate change on human health are large and diverse. The U.S. National Institutes of Health (NIH), through its basic, clinical, and population research portfolio of grants, has been increasing efforts to understand how the complex interrelationships among humans, ecosystems, climate, climate variability, and climate change affect domestic and global health. In this commentary we present a systematic review and categorization of the fiscal year (FY) 2008 NIH climate and health research portfolio. A list of candidate climate and health projects funded from FY 2008 budget appropriations were identified and characterized based on their relevance to climate change and health and based on climate pathway, health impact, study type, and objective. This analysis identified seven FY 2008 projects focused on climate change, 85 climate-related projects, and 706 projects that focused on disease areas associated with climate change but did not study those associations. Of the nearly 53,000 awards that NIH made in 2008, approximately 0.17% focused on or were related to climate. Given the nature and scale of the potential effects of climate change on human health and the degree of uncertainty that we have about these effects, we think that it is helpful for the NIH to engage in open discussions with science and policy communities about government-wide needs and opportunities in climate and health, and about how NIH's strengths in human health research can contribute to understanding the health implications of global climate change. This internal review has been used to inform more recent initiatives by the NIH in climate and health.

HAART has been available for close to two decades, and now a significant number of patients with access to HAART are over the age of 50 years. Many clinical studies have indicated that HIV infection, as well as components of HAART, can increase the risk in these individuals to a variety of noninfectious complications, including a risk to bone health. There is a significant need for detailed mechanistic analysis of the aging, HIV-infected population regarding the risk of HIV infection and therapy in order to maintain bone health. Insights from basic mechanistic studies will help to shed light on the role of HIV infection and the components of HAART that impact bone health, and will help in identifying preventative countermeasures, particularly for individuals 50 years of age and older.Keywords: osteopenia, osteomalacia, osteoporosis, bisphosphonates, tenofovir, osteoimmunology

Assessment of the Effects of Economic Sanctions on Iranians’ Right to Health by Using Human Rights Impact Assessment Tool: A Systematic Review

Science.gov (United States)

Kokabisaghi, Fatemeh

2018-01-01

Background: Over the years, economic sanctions have contributed to violation of right to health in target countries. Iran has been under comprehensive unilateral economic sanctions by groups of countries (not United Nations [UN]) in recent years. They have been intensified from 2012 because of international community’s uncertainty about peaceful purpose of Iran’s nuclear program and inadequacy of trust-building actions of this country. This review aimed to identify the humanitarian effects of the sanctions on the right of Iranians to health and the obligations of Iran and international community about it. Methods: To assess economic sanction policies and identify violated rights and the obligations of states according to international human rights laws, in this study, Human Rights Impact Assessments (HRIA) tool is used. Applying this tool requires collection of evidences regarding the situation of rights. To provide such evidence, a systematic review of literature which involved 55 papers retrieved from the web-based databases and official webpages of Iran’s government and UN’ health and human rights committees and organizations was done. All articles about the consequences of economic sanctions related to nuclear activities of Iran on welfare and health of Iranians published from January 2012 till February 2017 in English and Persian languages were included. Search terms were economic sanctions, embargoes, Iran, welfare, health and medicine. Additional studies were identified by cross checking the reference lists of accessed articles. All selected papers were abstracted and entered into a matrix describing study design and findings, and categorized into a framework of themes reflecting the areas covered (health and its determinants). According to HRIA framework, related obligations of Iran and other states about adverse effects of the sanctions on Iranians’ right to health were extracted. Results: The sanctions on Iran caused a fall of country�

Environmental health impacts of tobacco farming: a review of the literature.

To review the literature on environmental health impacts of tobacco farming and to summarise the findings and research gaps in this field. A standard literature search was performed using multiple electronic databases for identification of peer-reviewed articles. The internet and organisational databases were also used to find other types of documents (eg, books and reports). The reference lists of identified relevant documents were reviewed to find additional sources. The selected studies documented many negative environmental impacts of tobacco production at the local level, often linking them with associated social and health problems. The common agricultural practices related to tobacco farming, especially in low-income and middle-income countries, lead to deforestation and soil degradation. Agrochemical pollution and deforestation in turn lead to ecological disruptions that cause a loss of ecosystem services, including land resources, biodiversity and food sources, which negatively impact human health. Multinational tobacco companies' policies and practices contribute to environmental problems related to tobacco leaf production. Development and implementation of interventions against the negative environmental impacts of tobacco production worldwide are necessary to protect the health of farmers, particularly in low-income and middle-income countries. Transitioning these farmers out of tobacco production is ultimately the resolution to this environmental health problem. In order to inform policy, however, further research is needed to better quantify the health impacts of tobacco farming and evaluate the potential alternative livelihoods that may be possible for tobacco farmers globally.

An overwhelming body of research has now firmly established that the dietary intake of berry fruits has a positive and profound impact on human health, performance, and disease. Berry fruits, which are commercially cultivated and commonly consumed in fresh and processed forms in North America, include blackberry ( Rubus spp.), black raspberry ( Rubus occidentalis), blueberry ( Vaccinium corymbosum), cranberry (i.e., the American cranberry, Vaccinium macrocarpon, distinct from the European cranberry, V. oxycoccus), red raspberry ( Rubus idaeus) and strawberry ( Fragaria x ananassa). Other berry fruits, which are lesser known but consumed in the traditional diets of North American tribal communities, include chokecherry ( Prunus virginiana), highbush cranberry ( Viburnum trilobum), serviceberry ( Amelanchier alnifolia), and silver buffaloberry ( Shepherdia argentea). In addition, berry fruits such as arctic bramble ( Rubus articus), bilberries ( Vaccinuim myrtillus; also known as bog whortleberries), black currant ( Ribes nigrum), boysenberries ( Rubus spp.), cloudberries ( Rubus chamaemorus), crowberries ( Empetrum nigrum, E. hermaphroditum), elderberries ( Sambucus spp.), gooseberry ( Ribes uva-crispa), lingonberries ( Vaccinium vitis-idaea), loganberry ( Rubus loganobaccus), marionberries ( Rubus spp.), Rowan berries ( Sorbus spp.), and sea buckthorn ( Hippophae rhamnoides), are also popularly consumed in other parts of the world. Recently, there has also been a surge in the consumption of exotic "berry-type" fruits such as the pomegranate ( Punica granatum), goji berries ( Lycium barbarum; also known as wolfberry), mangosteen ( Garcinia mangostana), the Brazilian açaí berry ( Euterpe oleraceae), and the Chilean maqui berry ( Aristotelia chilensis).

Health impacts of power-exporting plants in northern Mexico

Blackman, Allen; Chandru, Santosh; Mendoza-Domínguez, Alberto; Russell, A.G.

2012-01-01

In the past two decades, rapid population and economic growth on the U.S.–Mexico border has spurred a dramatic increase in electricity demand. In response, American energy multinationals have built power plants just south of the border that export most of their electricity to the U.S. This development has stirred considerable controversy because these plants effectively skirt U.S. air pollution regulations in a severely degraded international airshed. Yet to our knowledge, this concern has not been subjected to rigorous scrutiny. This paper uses a suite of air dispersion, health impacts, and valuation models to assess the human health damages in the U.S. and Mexico caused by air emissions from two power-exporting plants in Mexicali, Baja California. We find that these emissions have limited but nontrivial health impacts, mostly by exacerbating particulate pollution in the U.S., and we value these damages at more than half a million dollars per year. These findings demonstrate that power-exporting plants can have cross-border health effects and bolster the case for systematically evaluating their environmental impacts. - Highlights: ► We estimate the health effects of emissions from Mexican electric power plants exporting to the U.S. ► The plants have limited but nontrivial effects, mostly from particulate pollution in the U.S. ► We value these damages at more than half a million dollars per year. ► Hence, power-exporting plants can have significant cross-border health effects.

Perceived and calculated health risks: do the impacts differ

In many cases of radioactive and hazardous waste management, some members of the general public perceive that human health risks associated with the wastes are higher than the calculated risks. Calculated risks are projections that have been derived from models, and it is these risks that are usually used as the basis for waste management. However, for various reasons, the calculated risks are often considered by the public as too low or inappropriate. The reasons that calculated risks are not perceived as accurate and the factors that affect these perceptions are explored in this paper. Also discussed are the impacts related to the perceived and calculated health risks: what they are, and if and how they differ. The kinds of potential impacts examined are health effects, land value changes, and social, transportation, and economic effects. The paper concludes with a discussion of the implications of incorporating these different risk perspectives in decisions on waste management

Anthropogenically-derived increases in atmospheric greenhouse gas concentrations have been implicated in recent climate change, and are projected to substantially impact the climate on a global scale in the future. For marine and freshwater systems, increasing concentrations of greenhouse gases are expected to increase surface temperatures, lower pH, and cause changes to vertical mixing, upwelling, precipitation, and evaporation patterns. The potential consequences of these changes for harmful algal blooms (HABs) have received relatively little attention and are not well understood. Given the apparent increase in HABs around the world and the potential for greater problems as a result of climate change and ocean acidification, substantial research is needed to evaluate the direct and indirect associations between HABs, climate change, ocean acidification, and human health. This research will require a multidisciplinary approach utilizing expertise in climatology, oceanography, biology, epidemiology, and other disciplines. We review the interactions between selected patterns of large-scale climate variability and climate change, oceanic conditions, and harmful algae. PMID:19025675

At a time of increasing disconnectedness from nature, scientific interest in the potential health benefits of nature contact has grown. Research in recent decades has yielded substantial evidence, but large gaps remain in our understanding. We propose a research agenda on nature contact and health, identifying principal domains of research and key questions that, if answered, would provide the basis for evidence-based public health interventions. We identify research questions in seven domains: a ) mechanistic biomedical studies; b ) exposure science; c ) epidemiology of health benefits; d ) diversity and equity considerations; e ) technological nature; f ) economic and policy studies; and g ) implementation science. Nature contact may offer a range of human health benefits. Although much evidence is already available, much remains unknown. A robust research effort, guided by a focus on key unanswered questions, has the potential to yield high-impact, consequential public health insights. https://doi.org/10.1289/EHP1663.

Electronic cigarettes: human health effects

Objective With the rapid increase in use of electronic nicotine delivery systems (ENDS), such as electronic cigarettes (e-cigarettes), users and non-users are exposed to the aerosol and product constituents. This is a review of published data on the human health effects of exposure to e-cigarettes and their components. Methods Literature searches were conducted through September 2013 using multiple electronic databases. Results Forty-four articles are included in this analysis. E-cigarette aerosols may contain propylene glycol, glycerol, flavourings, other chemicals and, usually, nicotine. Aerosolised propylene glycol and glycerol produce mouth and throat irritation and dry cough. No data on the effects of flavouring inhalation were identified. Data on short-term health effects are limited and there are no adequate data on long-term effects. Aerosol exposure may be associated with respiratory function impairment, and serum cotinine levels are similar to those in traditional cigarette smokers. The high nicotine concentrations of some products increase exposure risks for non-users, particularly children. The dangers of secondhand and thirdhand aerosol exposure have not been thoroughly evaluated. Conclusions Scientific evidence regarding the human health effects of e-cigarettes is limited. While e-cigarette aerosol may contain fewer toxicants than cigarette smoke, studies evaluating whether e-cigarettes are less harmful than cigarettes are inconclusive. Some evidence suggests that e-cigarette use may facilitate smoking cessation, but definitive data are lacking. No e-cigarette has been approved by FDA as a cessation aid. Environmental concerns and issues regarding non-user exposure exist. The health impact of e-cigarettes, for users and the public, cannot be determined with currently available data. PMID:24732161

Acid sulfate soils and human health--a Millennium Ecosystem Assessment.

Ljung, Karin; Maley, Fiona; Cook, Angus; Weinstein, Philip

2009-11-01

Acid sulfate soils have been described as the "nastiest soils on earth" because of their strong acidity, increased mobility of potentially toxic elements and limited bioavailability of nutrients. They only cover a small area of the world's total problem soils, but often have significant adverse effects on agriculture, aquaculture and the environment on a local scale. Their location often coincides with high population density areas along the coasts of many developing countries. As a result, their negative impacts on ecosystems can have serious implications to those least equipped for coping with the low crop yields and reduced water quality that can result from acid sulfate soil disturbance. The Millennium Ecosystem Assessment called on by the United Nations in 2000 emphasised the importance of ecosystems for human health and well-being. These include the service they provide as sources of food and water, through the control of pollution and disease, as well as for the cultural services ecosystems provide. While the problems related to agriculture, aquaculture and the environment have been the focus of many acid sulfate soil management efforts, the connection to human health has largely been ignored. This paper presents the potential health issues of acid sulfate soils, in relation to the ecosystem services identified in the Millennium Ecosystem Assessment. It is recognised that significant implications on food security and livelihood can result, as well as on community cohesiveness and the spread of vector-borne disease. However, the connection between these outcomes and acid sulfate soils is often not obvious and it is therefore argued that the impact of such soils on human well-being needs to be recognised in order to raise awareness among the public and decision makers, to in turn facilitate proper management and avoid potential human ill-health.

Because of past nuclear production operations along the Columbia River, there is intense public and tribal interest in assessing any residual Hanford Site related contamination along the river from the Hanford Reach to the Pacific Ocean. The Columbia River Impact Assessment (CRCIA) was proposed to address these concerns. The assessment of the Columbia River is being conducted in phases. The initial phase is a screening assessment of risk, which addresses current environmental conditions for a range of potential uses. One component of the screening assessment estimates the risk from contaminants in the Columbia River to humans. Because humans affected by the Columbia river are involved in a wide range of activities, various scenarios have been developed on which to base the risk assessments. The scenarios illustrate the range of activities possible by members of the public coming in contact with the Columbia River so that the impact of contaminants in the river on human health can be assessed. Each scenario illustrates particular activity patterns by a specific group. Risk will be assessed at the screening level for each scenario. This report defines the scenarios and the exposure factors that will be the basis for estimating the potential range of risk to human health from Hanford-derived radioactive as well as non-radioactive contaminants associated with the Columbia River.

Given the increase in wildfire intensity and frequency worldwide, prescribed burning is becoming a more common and widespread practice. Prescribed burning is a fire management tool used to reduce fuel loads for wildfire suppression purposes and occurs on an annual basis in many parts of the world. Smoke from prescribed burning can have a substantial impact on air quality and the environment. Prescribed burning is a significant source of fine particulate matter (PM2.5 aerodynamic diameterprescribed burning on air quality particularly focussing on PM2.5. We have summarised available case studies from Australia including a recent study we conducted in regional Victoria, Australia during the prescribed burning season in 2013. The studies reported very high short-term (hourly) concentrations of PM2.5 during prescribed burning. Given the increase in PM2.5 concentrations during smoke events, there is a need to understand the influence of prescribed burning smoke exposure on human health. This is important especially since adverse health impacts have been observed during wildfire events when PM2.5 concentrations were similar to those observed during prescribed burning events. Robust research is required to quantify and determine health impacts from prescribed burning smoke exposure and derive evidence based interventions for managing the risk. Given the increase in PM2.5 concentrations during PB smoke events and its impact on the local air quality, the need to understand the influence of PB smoke exposure on human health is important. This knowledge will be important to inform policy and practice of the integrated, consistent, and adaptive approach to the appropriate planning and implementation of public health strategies during PB events. This will also have important implications for land management and public health organizations in developing evidence based objectives to minimize the risk of PB smoke exposure.

How Health Humanities Will Save the Life of the Humanities.

Science.gov (United States)

Klugman, Craig M

2017-12-01

In the last decade, the humanities have been shrinking in number of students, percent of faculty, and in number of degrees awarded. Humanities students also earn lower salaries than their STEM-prepared peers. At the same time, the health humanities have been in ascendance over the last fifteen years. The number of majors, minors and certificates has increased 266% in that time frame, attracting large numbers of students and preparing future patients, lay caregivers, and health care providers to interact with a complicated and dehumanized medical system. In 1982, British philosopher and educator Stephen Toulmin declared that medicine saved philosophy from irrelevance and possibly extinction. I propose that the health humanities can serve a similar function to stave off the decline of the broader humanities. The health humanities can (1) model an applied approach for the broader humanities to attract student interest; (2) develop students' capacity for critical reading, writing and reflection about health and medicine in society, practice, and their own lives and (3) inoculate all students against the influence of medicine, whether through preparing pre-health students to navigate the hidden medical curriculum or preparing future patients to navigate the health care system.

Uptake of human pharmaceuticals in bull sharks (Carcharhinus leucas) inhabiting a wastewater-impacted river.

Gelsleichter, James; Szabo, Nancy J

2013-07-01

The presence of human pharmaceuticals in sewage-impacted ecosystems is a growing concern that poses health risks to aquatic wildlife. Despite this, few studies have investigated the uptake of active pharmaceutical ingredients (APIs) in aquatic organisms. In this study, the uptake of 9 APIs from human drugs was examined and compared in neonate bull sharks (Carcharhinus leucas) residing in pristine (Myakka River) and wastewater-impacted (Caloosahatchee River) tributaries of Florida's Charlotte Harbor estuary. The synthetic estrogen used in human contraceptives (17α-ethynylestradiol) and 6 of the selective serotonin/norepinephrine reuptake inhibitors (citalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine) used in human antidepressants were observed at detectable and, in some cases, quantifiable levels in plasma of Caloosahatchee River sharks. Comparatively, only venlafaxine was detected in the plasma of a single Myakka River shark at a level below the limit of quantitation. These results suggest that sharks residing in wastewater-impacted habitats accumulate APIs, a factor that may pose special risks to C. leucas since it is one of few shark species to regularly occupy freshwater systems. Further research is needed to determine if the low levels of API uptake observed in Caloosahatchee River bull sharks pose health risks to these animals. Copyright © 2013 Elsevier B.V.

Interventions directed to system features of public health and health care should increase health and welfare of patients and population. To build a new framework for studies aiming to assess the impact of public health or health care system, and to consider the role of Randomized Controlled Trials (RCTs) and of Benchmarking Controlled Trials (BCTs). The new concept is partly based on the author's previous paper on the Benchmarking Controlled Trial. The validity and generalizability considerations were based on previous methodological studies on RCTs and BCTs. The new concept System Impact Research (SIR) covers all the studies which aim to assess the impact of the public health system or of the health care system on patients or on population. There are two kinds of studies in System Impact Research: Benchmarking Controlled Trials (observational) and Randomized Controlled Trials (experimental). The term impact covers in particular accessibility, quality, effectiveness, safety, efficiency, and equality. System Impact Research - creating the scientific basis for policy decision making - should be given a high priority in medical, public health and health economic research, and should also be used for improving performance. Leaders at all levels of health and social care can use the evidence from System Impact Research for the benefit of patients and population. Key messages The new concept of SIR is defined as a research field aiming at assessing the impacts on patients and on populations of features of public health and health and social care systems or of interventions trying to change these features. SIR covers all features of public health and health and social care system, and actions upon these features. The term impact refers to all effects caused by the public health and health and social care system or parts of it, with particular emphasis on accessibility, quality, effectiveness, adverse effects, efficiency, and equality of services.

(Public) Health and Human Rights in Practice.

Science.gov (United States)

Annas, George J; Mariner, Wendy K

2016-02-01

Public health's reliance on law to define and carry out public activities makes it impossible to define a set of ethical principles unique to public health. Public health ethics must be encompassed within--and consistent with--a broader set of principles that define the power and limits of governmental institutions. These include human rights, health law, and even medical ethics. The human right to health requires governments not only to respect individual human rights and personal freedoms, but also, importantly, to protect people from harm from external sources and third parties, and to fulfill the health needs of the population. Even if human rights are the natural language for public health, not all public health professionals are comfortable with the language of human rights. Some argue that individual human rights--such as autonomy and privacy--unfairly limit the permissible means to achieve the goal of health protection. We argue that public health should welcome and promote the human rights framework. In almost every instance, this will make public health more effective in the long run, because the goals of public health and human rights are the same: to promote human flourishing.

The world is changing everyday in a fast pace that makes majority of the urbanized areas becoming more congested and polluted by the development. The planning of the urban world has brought about a great impact towards the environment and health. With the large number of human population, urban areas will have various kinds of activities that contributed to the higher rate of pollutants compared to areas with less development. In a car oriented urban development pattern, majority of the population will choose automobiles as their transportation modes rather than walking or cycling. Due to that, the air emission in urban areas will increase rapidly, and reduce the physical activity. Air pollutants contribute to various health problems, especially respiratory infection. Besides, lacking of physical activities also increase the health risk. However, there is limited study on the relationship between urban land use setting and health in developing country. Thus, a study had been carried out to establish the relationship between urban setting and human health. It involved air quality data collection, observation on land use setting, and questionnaire survey on human health and the lifestyle. Findings from the relationship analysis had been discussed with suitable recommendation and conclusion. (author)

Climate change is one of the greatest challenges facing the globe and there is substantial evidence that this will result in a number of health impacts, regardless of the level of greenhouse gas mitigation. It is therefore apparent that a combined approach of mitigation and adaptation will be required to protect public health. While the importance of mitigation is recognised, this project focused on the role of adaptation strategies in addressing the potential health impacts of climate change. The nature and magnitude of these health impacts will be determined by a number of parameters that are dependent upon the location. Firstly, climate change will vary between regions. Secondly, the characteristics of each region in terms of population and the ability to adapt to changes will greatly influence the extent of the health impacts that are experienced now and into the future. Effective adaptation measures therefore need to be developed with these differences in mind. A Health Impact Assessment (HIA) framework was used to consider the implications of climate change on the health of the population of Western Australia (WA) and to develop a range of adaptive responses suited to WA. A broad range of stakeholders participated in the HIA process, providing informed input into developing an understanding of the potential health impacts and potential adaptation strategies from a diverse sector perspective. Potential health impacts were identified in relation to climate change predictions in WA in the year 2030. The risk associated with each of these impacts was assessed using a qualitative process that considered the consequences and the likelihood of the health impact occurring. Adaptations were then developed which could be used to mitigate the identified health impacts and provide responses which could be used by Government for future decision making. The periodic application of a HIA framework is seen as an ideal tool to develop appropriate adaptation strategies to

Background: According to a wide variety of analyses and projections, the potential effects of global climate change on human health are large and diverse. The U.S. National Institutes of Health (NIH), through its basic, clinical, and population research portfolio of grants, has been increasing efforts to understand how the complex interrelationships among humans, ecosystems, climate, climate variability, and climate change affect domestic and global health. Objectives: In this commentary we present a systematic review and categorization of the fiscal year (FY) 2008 NIH climate and health research portfolio. Methods: A list of candidate climate and health projects funded from FY 2008 budget appropriations were identified and characterized based on their relevance to climate change and health and based on climate pathway, health impact, study type, and objective. Results: This analysis identified seven FY 2008 projects focused on climate change, 85 climate-related projects, and 706 projects that focused on disease areas associated with climate change but did not study those associations. Of the nearly 53,000 awards that NIH made in 2008, approximately 0.17% focused on or were related to climate. Conclusions: Given the nature and scale of the potential effects of climate change on human health and the degree of uncertainty that we have about these effects, we think that it is helpful for the NIH to engage in open discussions with science and policy communities about government-wide needs and opportunities in climate and health, and about how NIH’s strengths in human health research can contribute to understanding the health implications of global climate change. This internal review has been used to inform more recent initiatives by the NIH in climate and health. PMID:23552460

Metals in wine--impact on wine quality and health outcomes.

2011-12-01

Metals in wine can originate from both natural and anthropogenic sources, and its concentration can be a significant parameter affecting consumption and conservation of wine. Since metallic ions have important role in oxide-reductive reactions resulting in wine browning, turbidity, cloudiness, and astringency, wine quality depends greatly on its metal composition. Moreover, metals in wine may affect human health. Consumption of wine may contribute to the daily dietary intake of essential metals (i.e., copper, iron, and zinc) but can also have potentially toxic effects if metal concentrations are not kept under allowable limits. Therefore, a strict analytical control of metal concentration is required during the whole process of wine production. This article presents a critical review of the existing literature regarding the measured metal concentration in wine, methods applied for their determination, and possible sources, as well as their impact on wine quality and human health. The main focus is set on aluminum, arsenic, cadmium, chromium, copper, iron, manganese, nickel, lead, and zinc, as these elements most often affect wine quality and human health.

Present paper deals with Radiation Environment Assessment, Measurement and its Impact on Health, its meaning and in particular with sustainable development perspective. Health and Environment appears to be different subjects and concepts, but in reality they are interrelated and interdependent. One cannot exist without the other. For good health hygienic environment is a sine qua non. Article 3 of Universal Declaration of Human Right 1948 incorporates the right to life. It has been interpreted by the international court that the word life does not means simply to live but it means to live with dignity and in well and pollution and radiation free environment which is a gift of nature on this universe. There is no doubt about the nuclear revolution that has taken place and has made life of human beings worth living on this earth with comfort. It is growing development of the nation. But in the process the development that has been done at the cost of human life, public health and environment which will prove fatal in the long run. So there is a need for Sustainable Development of the human and environment of the world. Precisely and concisely, the sustainable development is a process that meets the needs of the present without compromising ability of future generations to meet their own needs. A hygienic and redaction free environment will ensure the better Health of the people. Environment and nuclear power plant can coexist. The harmonization of the two needs has led to the concept of Radiation Environment Assessment and sustainable development, so much so that it has become the most significant and focal point of environmental legislation relating to the same. Sustainable development, simply put, is a process in which development can be sustained over generations effects of radiation on humans and on the environment. Finally, this paper deals with the impact of radiation on environment and the need of sustainable development for achieving a better human. (author)

Air Pollution and Climate Change Health Impact Assessment. The ACHIA Project

Kinney, P.L.

2013-01-01

Climate change may affect human health via interactions with air pollutants such as ozone and PM 2.5 . These air pollutants are linked to climate because they can be both affected by and have effects on climate. In coming decades, substantial, cost-effective improvements in public health may be achieved with well-planned strategies to mitigate climate impacts while also reducing health effects of ozone and PM 2.5 . Climate mitigation actions affect greenhouse pollutant emissions, including methane and black carbon, but also may affect other key air pollution precursors such as NOx, CO, and SOx. To better understand the potential of such strategies, studies are needed that assess possible future health impacts under alternative assumptions about future emissions and climate across multiple spatial scales. The overall objective of this project is to apply state of the art climate, air quality, and health modelling tools to assess future health impacts of ozone and PM 2.5 under different IPCCs scenario of climate change, focusing specifically on pollution-related health co-benefits which could be achieved under alternative climate mitigation pathways in the period 2030-2050. This question will be explored at three spatial scales: global, regional (Europe), and urban (Paris). ACHIA is comprised of an integrated set of four work packages: WP1. Global Climate and Air Pollution Impacts of Alternative Emissions Pathways; WP2. Climate and Air Quality at Regional and Urban Scales: Results for Europe and Paris; WP3. Health Impact Assessment; WP4. Dissemination, Evaluation, Management. ACHIA is designed to create an interdisciplinary approach to the impacts of climate change on health through air quality changes, and to start longer-term collaborations between communities. We expect the project to advance state of art across all WPs, with important implications for research groups around the world. A particular innovation of the project is the multi-scale aspect, i.e., the

Life cycle assessment (LCA) is a powerful methodology for the study of health impacts and public policies. We performed this study to quantitatively explain the potential health impacts on disability-adjusted life years (DALYs) of corn produced in Mexico and imported from the United States of America (U.S.) from 1984 until 2014. The processes are hybrid and organic corn production. The functional unit was defined as 1 ton of corn production. Results indicate a total value of 178,431, 244,175, and 283,426 DALYs of three decades: 1984-1993, 1994-2003, and 2004-2013, of Mexican production; the U.S. production and transport were also calculated, showing values of 29,815, 65,837, and 107,729 for the same three decades. Additionally, DALYs were obtained for the category of human health and climate change by functional unit: 802.31 (1984-1993), 802.67 (1994-2003), and 803.92 (2004-2013), and for imported corn transported to Mexico from the U.S., 859.12 (1984-2013). DALYs on human toxicity were obtained: 99.05 (1984-1993), 99.05 (1994-2003), and 99.04 (2004-2013), and for the corn imported and transported to Mexico from the U.S., 116.25 (1984-2013). Environmental and health impacts in terms of DALYs are higher when corn is imported versus the corn produced in Mexico. Environmental health and nominal corn cultivation and transport impacts have increased as a result of the North American Free Trade Agreement (NAFTA). Mexico needs to redefine its public policies to suffer less of an environmental burden from corn to ensure global environmental health and food security.

The impact of stroke aphasia on health and well-being and appropriate nursing interventions: an exploration using the Theory of Human Scale Development.

This paper considers the impact of aphasia on health and well-being and provides suggestions for appropriate nursing interventions. Background.  Effective communication is essential to holistic care and positive outcomes for individuals affected by aphasia. When verbal communication is absent, nurses fail to adequately use alternative strategies so that the standard of nurse/patient communication is frequently poor. This is a discursive paper which reviews relevant literature and uses the Theory of Human Scale Development as a framework for discussion. The Theory of Human Scale Development is introduced. This theory emphasises that quality of life depends as much upon self-actualisation and relation building as on physical health. The theory is used within the discussion to highlight the significance of communication to quality of life and how its loss has profound psychological and social consequences. Aphasia results in 'loss of self'. The situation is exacerbated by inadequate healthcare communication strategies. Suggestions are offered regarding more appropriate strategies. Efficacy of family input is considered; nursing competence regarding language practice therapies is discussed, and the 'quest approach' is explored. Aphasia has a negative impact on relationships by denying access to support networks, which results in isolation. The individual's predicament is worsened by negative nursing responses. Positive nursing strategies, which alleviate effects of aphasia on individuals' social health, are investigated. Concept analysis and self-awareness exercises as methods of enhancing compassion skills are explored. The social model of disability is discussed to highlight the benefits to individuals of environmental adaptations. The social benefits of aphasia-group affiliation are discussed. The paper concludes by emphasising that fundamental human needs involve social and psychological as well as physical aspects. Nursing interventions must address all needs to

According to the World Health Organization (WHO), air pollution is now the world's largest single environmental health risk. Assessments of health impacts and the associated external costs related to air pollution are estimated based on observed and/or modelled air pollutant levels. Chemistry and transport models (CTMs) are useful tools to calculate the concentrations of health-related pollutants taking into account the non-linearities in the chemistry and the complex interactions between meteorology and chemistry. However, the CTMs include different chemical and aerosol schemes that introduce differences in the representation of the processes. Likewise, will differences in the emissions and boundary conditions used in the models add to the overall uncertainties. These uncertainties are introduced also into the health impact estimates using output from the CTMs. Multi-model (MM) ensembles can be useful to minimize these uncertainties introduced by the individual CTMs. In the present study, the simulated surface concentrations of health related air pollutants for the year 2010 from fifteen modelling groups participating in the AQMEII exercise, serve as input to the Economic Valuation of Air Pollution model (EVA), in order to calculate the impacts of these pollutants on human health and the associated external costs in Europe and U.S. In addition, the impacts of a 20% global emission reduction scenario on the human health and associated costs have been calculated. Preliminary results show that in Europe and U.S., the MM mean number of premature deaths due to air pollution is calculated to be 400 000 and 160 000, respectively. Estimated health impacts among different models can vary up to a factor of 3 and 1.2 in Europe and U.S., respectively. PM is calculated to be the major pollutant affecting the health impacts and the differences in models regarding the treatment of aerosol composition, physics and dynamics is a key factor. The total MM mean costs due to health

Objective To inform policy by providing an overview of systematic reviews on interventions that facilitate sustainable energy use and have a positive impact on health. Methods Systematic review methods were used to synthesize evidence from multiple systematic reviews and economic evaluations through a comprehensive search of 13 databases and nine websites based on a pre-defined protocol, including clear inclusion criteria. Both grey and peer-reviewed literature published in English, Spanish, and Portuguese during the 17 years from January 1997 - January 2014 was included. To classify as "sustainable," interventions needed to aim to positively impact at least two dimensions of the integrated framework for sustainable development and include measures of health impact. Results Five systematic reviews and one economic evaluation met the inclusion criteria. The most promising interventions that impacted health were electricity for lighting and other uses (developing countries); improved stoves for cooking and health and/or cleaner fuels for cooking (developing countries); and household energy efficiency measures (developed countries). These interventions also had potential environmental and economic impacts. Their cost-effectiveness is not known, nor is their impact on health inequalities. Conclusions What is needed now is careful implementation of interventions where the impacts are likely to be positive but their implementation needs to be rigorously evaluated, including possible adverse impacts. Care needs to be taken not to exacerbate health inequalities and to consider context, human behavior and cultural factors so that the potential health benefits are realized in real-life implementation. Possible impact on health inequalities needs to be considered and measured in future primary studies and systematic reviews.

Occupational Health Impacts Due to Exposure to Organic Chemicals over an Entire Product Life Cycle.

Kijko, Gaël; Jolliet, Olivier; Margni, Manuele

2016-12-06

This article presents an innovative approach to include occupational exposures to organic chemicals in life cycle impact assessment (LCIA) by building on the characterization factors set out in Kijko et al. (2015) to calculate the potential impact of occupational exposure over the entire supply chain of product or service. Based on an economic input-output model and labor and economic data, the total impacts per dollar of production are provided for 430 commodity categories and range from 0.025 to 6.6 disability-adjusted life years (DALY) per million dollar of final economic demand. The approach is applied on a case study assessing human health impacts over the life cycle of a piece of office furniture. It illustrates how to combine monitoring data collected at the manufacturing facility and averaged sector specific data to model the entire supply chain. This paper makes the inclusion of occupational exposure to chemicals fully compatible with the LCA framework by including the supply chain of a given production process and will help industries focus on the leading causes of human health impacts and prevent impact shifting.

Bridging international law and rights-based litigation: mapping health-related rights through the development of the Global Health and Human Rights Database.

2012-06-15

The O'Neill Institute for National and Global Health Law at Georgetown University, the World Health Organization, and the Lawyers Collective have come together to develop a searchable Global Health and Human Rights Database that maps the intersection of health and human rights in judgments, international and regional instruments, and national constitutions. Where states long remained unaccountable for violations of health-related human rights, litigation has arisen as a central mechanism in an expanding movement to create rights-based accountability. Facilitated by the incorporation of international human rights standards in national law, this judicial enforcement has supported the implementation of rights-based claims, giving meaning to states' longstanding obligations to realize the highest attainable standard of health. Yet despite these advancements, there has been insufficient awareness of the international and domestic legal instruments enshrining health-related rights and little understanding of the scope and content of litigation upholding these rights. As this accountability movement evolves, the Global Health and Human Rights Database seeks to chart this burgeoning landscape of international instruments, national constitutions, and judgments for health-related rights. Employing international legal research to document and catalogue these three interconnected aspects of human rights for the public's health, the Database's categorization by human rights, health topics, and regional scope provides a comprehensive means of understanding health and human rights law. Through these categorizations, the Global Health and Human Rights Database serves as a basis for analogous legal reasoning across states to serve as precedents for future cases, for comparative legal analysis of similar health claims in different country contexts, and for empirical research to clarify the impact of human rights judgments on public health outcomes.

Widespread use of antibiotics in human, veterinary medicine and agricultural settings has played a significant role in the emergence of resistant MRSA clones due to selection pressure. MRSA has now become established in human population as well as in various animal species. An animal associated clone, MRSA ST 398 has been reported from animal foods and also from human infections in the community as well as from the health care associated infections. Clonal relationship between strains of animal and human origins are indicators of interspecies transmission of clones. Spread of these organisms may pose a great impact on public health if animal associated strains enter into the community and health care settings. Surveillance is important to correlate the genetic changes associated with their epidemiological shift and expansion to predict its impact on public health. Strict regulations on the use of antibiotics in humans as well as in animal food production are required to control the emergence of drug resistant clones. t0 his article reviews the information available on the role of antibiotics in emergence of MRSA strains, their epidemiological shift between humans and animals and its impact on the public health.

Air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment. It has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution. According to the World Health Organization, six major air pollutants include particle pollution, ground-level ozone, carbon monoxide, sulfur oxides, nitrogen oxides, and lead. Long and short term exposure to air suspended toxicants has a different toxicological impact on human including respiratory and cardiovascular diseases, neuropsychiatric complications, the eyes irritation, skin diseases, and long-term chronic diseases such as cancer. Several reports have revealed the direct association between exposure to the poor air quality and increasing rate of morbidity and mortality mostly due to cardiovascular and respiratory diseases. Air pollution is considered as the major environmental risk factor in the incidence and progression of some diseases such as asthma, lung cancer, ventricular hypertrophy, Alzheimer's and Parkinson's diseases, psychological complications, autism, retinopathy, fetal growth, and low birth weight. In this review article, we aimed to discuss toxicology of major air pollutants, sources of emission, and their impact on human health. We have also proposed practical measures to reduce air pollution in Iran.

Recent clinical studies show that the contour of the photoplethysmogram (PPG) wave contains valuable information for characterizing cardiovascular activity. However, analyzing the PPG wave contour is difficult; therefore, researchers have applied first or higher order derivatives to emphasize and conveniently quantify subtle changes in the filtered PPG contour. Our hypothesis is that analyzing the whole PPG recording rather than each PPG wave contour or on a beat-by-beat basis can detect heat-stressed subjects and that, consequently, we will be able to investigate the impact of global warming on human health. Here, we explore the most suitable derivative order for heat stress assessment based on the energy and entropy of the whole PPG recording. The results of our study indicate that the use of the entropy of the seventh derivative of the filtered PPG signal shows promising results in detecting heat stress using 20-second recordings, with an overall accuracy of 71.6%. Moreover, the combination of the entropy of the seventh derivative of the filtered PPG signal with the root mean square of successive differences, or RMSSD (a traditional heart rate variability index of heat stress), improved the detection of heat stress to 88.9% accuracy.

Microalgal blooms are a natural part of the seasonal cycle of photosynthetic organisms in marine ecosystems. They are key components of the structure and dynamics of the oceans and thus sustain the benefits that humans obtain from these aquatic environments. However, some microalgal blooms can cause harm to humans and other organisms. These harmful algal blooms (HABs) have direct impacts on human health and negative influences on human wellbeing, mainly through their consequences to coastal ecosystem services (fisheries, tourism and recreation) and other marine organisms and environments. HABs are natural phenomena, but these events can be favoured by anthropogenic pressures in coastal areas. Global warming and associated changes in the oceans could affect HAB occurrences and toxicity as well, although forecasting the possible trends is still speculative and requires intensive multidisciplinary research. At the beginning of the 21st century, with expanding human populations, particularly in coastal and developing countries, mitigating HABs impacts on human health and wellbeing is becoming a more pressing public health need. The available tools to address this global challenge include maintaining intensive, multidisciplinary and collaborative scientific research, and strengthening the coordination with stakeholders, policymakers and the general public. Here we provide an overview of different aspects of the HABs phenomena, an important element of the intrinsic links between oceans and human health and wellbeing. PMID:26692586

Reliability, Resilience, and Vulnerability criteria for the evaluation of Human Health Risks

Understanding the impact of water quality on the health of a general population is challenging due high degrees of uncertainty and variability in hydrological, toxicological and human aspects of the system. Assessment of the impact of changes in water quality of a public water supply is critical to management of that water supply. We propose the use of three different system evaluation criteria: Reliability, Resilience and Vulnerability (RRV) as a tool for assessing the impact of uncertainty in the arrival of contaminant mass through time with respect to human health risks on a variable population. These criteria were first introduced to the water resources community by Hashimoto et al (1982). Most simply one can understand these criteria as the following: Reliability is the likelihood of the system being in a state of success; Resilience is the probability that the system will return to a state of success at t+1 if it is in failure at time step t, and Vulnerability is the severity of failure, which here is defined as the maximum health risk. These concepts are applied to a theoretical example where the water quality at a water supply well varies over time: health impact is considered based on sliding, 30-year windows of exposure to water derived from the well. We apply the methodology, in terms of uncertainty in water quality deviations, to eight simulated breakthrough curves of a contaminant at the well: each curve represents equal mass of contaminant arriving at the well over a 70-year lifetime of the well, but different mass distributions over time. These curves are used to investigate the impact of uncertainty in the distribution through time of the contaminant mass at the well, as well as the initial arrival of the contaminant over the 70-year lifetime of the well. In addition to extending the health risk through time with uncertainty in mass distribution, we incorporate variability in the human population to examine the evolution of the three criteria within

Full Text Available This paper reviews information from the existing literature and the EU GMOS (Global Mercury Observation System project to assess the current scientific knowledge on global mercury releases into the atmosphere, on global atmospheric transport and deposition, and on the linkage between environmental contamination and potential impacts on human health. The review concludes that assessment of global sources and pathways of mercury in the context of human health is important for being able to monitor the effects from implementation of the Minamata Convention targets, although new research is needed on the improvement of emission inventory data, the chemical and physical behaviour of mercury in the atmosphere, the improvement of monitoring network data, predictions of future emissions and speciation, and on the subsequent effects on the environment, human health, as well as the economic costs and benefits of reducing these aspects.

Assessment of the Effects of Economic Sanctions on Iranians' Right to Health by Using Human Rights Impact Assessment Tool: A Systematic Review.

Over the years, economic sanctions have contributed to violation of right to health in target countries. Iran has been under comprehensive unilateral economic sanctions by groups of countries (not United Nations [UN]) in recent years. They have been intensified from 2012 because of international community's uncertainty about peaceful purpose of Iran's nuclear program and inadequacy of trust-building actions of this country. This review aimed to identify the humanitarian effects of the sanctions on the right of Iranians to health and the obligations of Iran and international community about it. To assess economic sanction policies and identify violated rights and the obligations of states according to international human rights laws, in this study, Human Rights Impact Assessments (HRIA) tool is used. Applying this tool requires collection of evidences regarding the situation of rights. To provide such evidence, a systematic review of literature which involved 55 papers retrieved from the web-based databases and official webpages of Iran's government and UN' health and human rights committees and organizations was done. All articles about the consequences of economic sanctions related to nuclear activities of Iran on welfare and health of Iranians published from January 2012 till February 2017 in English and Persian languages were included. Search terms were economic sanctions, embargoes, Iran, welfare, health and medicine. Additional studies were identified by cross checking the reference lists of accessed articles. All selected papers were abstracted and entered into a matrix describing study design and findings, and categorized into a framework of themes reflecting the areas covered (health and its determinants). According to HRIA framework, related obligations of Iran and other states about adverse effects of the sanctions on Iranians' right to health were extracted. The sanctions on Iran caused a fall of country's revenues, devaluation of national currency, and

Changes in climate, in conjunction with other drivers of mobility, shape human migration. While there is an increasing focus on the adaptive potential of migration, the health impacts of climate-related migration, including planned relocation and forced displacement, have not been thoroughly examined. The Intergovernmental Panel on Climate Change stated that migration is currently, and will increasingly be, influenced by environmental degradation and climate change, and that it needs to be addressed in a focused and coordinated manner. This paper examines the links between climate change, migration, and health, considering diverse migration responses, including immobility, forced displacement and planned migration, as well as the associated health risks and opportunities in different contexts. Using case studies, the paper illustrates strategies to reduce the health risks associated with climate change-related migration. While there is an increasing body of research examining the climate change-migration nexus, a dual approach is now required. This approach must include debate and further research regarding the health consequences and responses associated with climate migration as well as immediate strengthening of health systems to make them both climate resilient and migrant inclusive.

We present a probabilistic framework for assessing human health risk due to groundwater contamination. Our goal is to quantify how physical hydrogeological and biochemical parameters control the magnitude and uncertainty of human health risk. Our methodology captures the whole risk chain from the aquifer contamination to the tap water assumption by human population. The contaminant concentration, the key parameter for the risk estimation, is governed by the interplay between the large-scale advection, caused by heterogeneity and the degradation processes strictly related to the local scale dispersion processes. The core of the hazard identification and of the methodology is the reactive transport model: erratic displacement of contaminant in groundwater, due to the spatial variability of hydraulic conductivity (K), is characterized by a first-order Lagrangian stochastic model; different dynamics are considered as possible ways of biodegradation in aerobic and anaerobic conditions. With the goal of quantifying uncertainty, the Beta distribution is assumed for the concentration probability density function (pdf) model, while different levels of approximation are explored for the estimation of the one-point concentration moments. The information pertaining the flow and transport is connected with a proper dose response assessment which generally involves the estimation of physiological parameters of the exposed population. Human health response depends on the exposed individual metabolism (e.g. variability) and is subject to uncertainty. Therefore, the health parameters are intrinsically a stochastic. As a consequence, we provide an integrated in a global probabilistic human health risk framework which allows the propagation of the uncertainty from multiple sources. The final result, the health risk pdf, is expressed as function of a few relevant, physically-based parameters such as the size of the injection area, the Péclet number, the K structure metrics and

Human rights approach to health.

Haigh, Fiona

Adopting human rights approach to health carries many benefits, because it emphasizes the equality of all persons and their inherent right to health as the foundation of the health care system. It also argues that promotion and protection of health are fundamentally important social goals, focuses particularly on the needs of the most disadvantaged and vulnerable communities, balances individual needs with the common good, and so forth. However, it also raises some practical issues, such as organization of interdisciplinary education and work, and different use of the language, which often goes unacknowledged. The relationship between human rights and health is a reciprocal one, and can be beneficial or harmful. For the relationship to be beneficial and successful, the differences between human rights and public health approach to health, centered around the perspective taking, attitudes, and abilities of health professionals, need to be acknowledged and reconciled, and the need for interdisciplinarity adequately fulfilled.

Health is an important part of human life. Every person in this world want healthy body, in other words free of any disease. When seeing the pattern of human life today is high activity, always eat instant foods and lack of exercise makes a very bad human health from year to year. Therefore, there is need for the health revolution that can keep human health in order to remain in the condition is always healthy. Eat healthy foods four plus five perfect diligent exercise is the real solution to maintain health. In addition also advisable to always check each month to the doctor so that our health can be controlled. Most people underestimate it, especially the routine checks once a month to the doctor, therefore I created a simple research that aims to get people to mengonytrol health at any time without having to check into the doctor. By utilizing the resistance in the human body's health so we can be controlled. By using a simple tool to measure human resistance by using the concept of the bridge. Bridge circuit used to convert impedance variations into voltage variations. One advantage of this circuit is the voltage produced can vary around 0. This means strengthening can be used to raise the voltage level so as sensitivity to variations in impedance also increases. Another application is the impedance measurement accuracy. The bridge is the simplest and most widely used is the Wheatstone bridge circuit. This circuit is used for signal conditioning applications where a sensor can change the resistance value when the process variable is changed.

The need to understand how healthcare worker reform policy interventions impact health personnel in peri-urban areas is important as it also contributes towards setting of priorities in pursuing the universal health coverage goal of health sector reform. This study explored the impact of post 2008 human resource for health reform policy interventions on healthcare workers in Epworth, a peri-urban community in Harare, Zimbabwe, and the implications towards health sector reform policy in peri-urban areas. The study design was exploratory and cross-sectional and involved the use of qualitative and quantitative methods in data collection, presentation, and analysis. A qualitative study in which data were collected through a documentary search, five key informant interviews, seven in-depth interviews, and five focus group discussions was carried out first. This was followed by a quantitative study in which data were collected through a documentary search and 87 semi-structured sample interviews with healthcare workers. Qualitative data were analyzed thematically whilst descriptive statistics were used to examine quantitative data. All data were integrated during analysis to ensure comprehensive, reliable, and valid analysis of the dataset. Three main factors were identified to help interpret findings. The first main factor consisted policy result areas that impacted most successfully on healthcare workers. These included the deployment of community health workers with the highest correlation of 0.83. Policy result areas in the second main factor included financial incentives with a correlation of 0.79, training and development (0.77), deployment (0.77), and non-financial incentives (0.75). The third factor consisted policy result areas that had the lowest satisfaction amongst healthcare workers in Epworth. These included safety (0.72), equipment and tools of trade (0.72), health welfare (0.65), and salaries (0.55). The deployment of community health volunteers impacted

middle-/high-income countries (62%), despite the fact that low-income countries bear a disproportionate share of the burden on morbidity and mortality from CCRWDs. Empirical evidence related to CCRWDs is predominately descriptive in nature, characterizing the cascade of climatic shifts leading to major environmental disruption and exposure to toxins, and their resultant morbidity and mortality. There is inadequate representation of research exploring potentially modifiable factors associated with CCRWDs and their impact on population health. This review lays the foundation for a wide array of further areas of analysis to explore the negative health impacts of CCRWDs and for nurses to take a leadership role in identifying and advocating for evidence-based policies to plan, prevent, or mitigate these effects. Nurses comprise the largest global healthcare workforce and are in a position to advocate for disaster preparedness for CCRWDs, develop more robust environmental health policies, and work towards mitigating exposure to environmental toxins that may threaten human health. © 2017 Sigma Theta Tau International.

Climate change and degradation of ecosystem services functioning may threaten the ability of current agricultural systems to keep up with demand for adequate and inexpensive food and for clean water, waste disposal and other broader ecosystem services. Human health is likely to be affected by changes occurring across multiple geographic and time scales. Impacts range from increasing transmissibility and the range of vector-borne diseases, such as malaria and yellow fever, to undermining nutrition through deleterious impacts on food production and concomitant increases in food prices. This paper uses case studies to describe methods that make use of satellite remote sensing and Demographic and Health Survey data to better understand individual-level human health and nutrition outcomes. By bringing these diverse datasets together, the connection between environmental change and human health outcomes can be described through new research and analysis.

A Review of Adverse Effects of Road Traffic Noise on Human Health

Science.gov (United States)

Singh, Devi; Kumari, Neeraj; Sharma, Pooja

Noise pollution due to road traffic is a potential threat to human health. Since it is a global hazard, the rapid urbanization and exponential traffic growth have aggravated the problem. Population residing along the busy traffic lanes is continuously exposed to the sound levels which are above the permissible limits. This constant exposure to noise pollution is a cause of concern as it leads to several adverse impacts on human health. Traffic noise causes irritation and annoyance, sleep disturbances, cardiovascular disease, risk of stroke, diabetes, hypertension and loss of hearing. It results in decreased work performance. The present review highlights the serious health hazards of road traffic noise (RTN) which needs to be curbed. Preventive measures of noise pollution can help in combating noise-induced health hazards and increased work performance.

In May 2007, what was then the Space Life Sciences Directorate, issued the 2007 Space Life Sciences Strategy for Human Space Exploration. In January 2012, leadership and key directorate personnel were once again brought together to assess the current and expected future environment against its 2007 Strategy and the Agency and Johnson Space Center goals and strategies. The result was a refined vision and mission, and revised goals, objectives, and strategies. One of the first changes implemented was to rename the directorate from Space Life Sciences to Human Health and Performance to better reflect our vision and mission. The most significant change in the directorate from 2007 to the present is the integration of the Human Research Program and Crew Health and Safety activities. Subsequently, the Human Health and Performance Directorate underwent a reorganization to achieve enhanced integration of research and development with operations to better support human spaceflight and International Space Station utilization. These changes also enable a more effective and efficient approach to human system risk mitigation. Since 2007, we have also made significant advances in external collaboration and implementation of new business models within the directorate and the Agency, and through two newly established virtual centers, the NASA Human Health and Performance Center and the Center of Excellence for Collaborative Innovation. Our 2012 Strategy builds upon these successes to address the Agency's increased emphasis on societal relevance and being a leader in research and development and innovative business and communications practices. The 2012 Human Health and Performance Vision is to lead the world in human health and performance innovations for life in space and on Earth. Our mission is to enable optimization of human health and performance throughout all phases of spaceflight. All HH&P functions are ultimately aimed at achieving this mission. Our activities enable

The impact of climate change on human and environmental health is of critical concern. Population exposures to air pollutants both indoors and outdoors are influenced by a wide range of air quality, meteorological, behavioral, and housing-related factors, many of which are also impacted by climate change. An integrated methodology for modeling changes in human exposures to tropospheric ozone (O 3 ) owing to potential future changes in climate and demographics was implemented by linking existing modeling tools for climate, weather, air quality, population distribution, and human exposure. Human exposure results from the Air Pollutants Exposure Model (APEX) for 12 US cities show differences in daily maximum 8-h (DM8H) exposure patterns and levels by sex, age, and city for all scenarios. When climate is held constant and population demographics are varied, minimal difference in O 3 exposures is predicted even with the most extreme demographic change scenario. In contrast, when population is held constant, we see evidence of substantial changes in O 3 exposure for the most extreme change in climate. Similarly, we see increases in the percentage of the population in each city with at least one O 3 exposure exceedance above 60 p.p.b and 70 p.p.b thresholds for future changes in climate. For these climate and population scenarios, the impact of projected changes in climate and air quality on human exposure to O 3 are much larger than the impacts of changing demographics. These results indicate the potential for future changes in O 3 exposure as a result of changes in climate that could impact human health.

Human impact gradient on mammalian biodiversity

Full Text Available Drastic changes have been caused by human influence in natural landscapes, which may exert an intensive effect on species loss. However, species loss from human pressure is not random but depends on a series of environmentally associated factors. Linking species traits to environmental attributes may allow us to detect the ecological impacts of habitat so that meaningful habitat degradation gradients can be identified. The relationships between environmental factors and species traits provide the basis for identifying those biological traits that make species more sensitive to disturbance. These relationships are also helpful to detect the geographic distribution of latent risk to reveal areas where biodiversity is threatened. Here, we identify a “Human Impact Gradient for Biodiversity (HIGB” based on a three-table ordination method (RLQ analysis and fourth-corner analysis to identify key species traits that are associated with environmental gradient. Species distribution and environmental geographic data were gathered nationwide to analyze 68 localities, which represent 27% of Mexico’s surface, including 211 species of mammals. Nine environmental variables (including biophysical, geophysical and land-use impacts were analyzed by using the Geographic Information System. Three types of species’ traits were evaluated: locomotion, trophic habit and body size. We identified a human impact gradient, which was mainly determined by the percentage of the area that was covered by seedlings, the plant richness, the understory coverage percentage and the human settlement index. The most important species traits that are associated with non-human-impacted sites were carnivores, frugivores–herbivores and a body size that was greater than 17.8 kg; 25 species were selected by the decision criteria framework for species that were sensitive to degradation based on ecological function information. Conversely, granivores, fossorial and semifossorial

Full Text Available Since the mid-19th century, human activities have increased greenhouse gases such as carbon dioxide, methane, and nitrous oxide in the Earth's atmosphere that resulted in increased average temperature. The effects of rising temperature include soil degradation, loss of productivity of agricultural land, desertification, loss of biodiversity, degradation of ecosystems, reduced fresh-water resources, acidification of the oceans, and the disruption and depletion of stratospheric ozone. All these have an impact on human health, causing non-communicable diseases such as injuries during natural disasters, malnutrition during famine, and increased mortality during heat waves due to complications in chronically ill patients. Direct exposure to natural disasters has also an impact on mental health and, although too complex to be quantified, a link has even been established between climate and civil violence.

Pleuromutilins (tiamulin and valnemulin) are antimicrobial agents that are used mainly in veterinary medicine, especially for swine and to a lesser extent for poultry and rabbits. In pigs, tiamulin and valnemulin are used to treat swine dysentery, spirochaete-associated diarrhoea, porcine proliferative enteropathy, enzootic pneumonia and other infections where Mycoplasma is involved. There are concerns about the reported increases in the MICs of tiamulin and valnemulin for porcine Brachyspira hyodysenteriae isolates from different European countries, as only a limited number of antimicrobials are available for the treatment of swine dysentery where resistance to these antimicrobials is already common and widespread. The loss of pleuromutilins as effective tools to treat swine dysentery because of further increases in resistance or as a consequence of restrictions would present a considerable threat to pig health, welfare and productivity. In humans, only one product containing pleuromutilins (retapamulin) is authorized currently for topical use; however, products for oral and intravenous administration to humans with serious multidrug-resistant skin infections and respiratory infections, including those caused by methicillin-resistant Staphylococcus aureus (MRSA), are being developed. The objective of this review is to summarize the current knowledge on the usage of pleuromutilins, resistance development and the potential impact of this resistance on animal and human health. © The Author 2014.

This review summarises existing evidence on the impact of organic food on human health. It compares organic vs. conventional food production with respect to parameters important to human health and discusses the potential impact of organic management practices with an emphasis on EU conditions. Organic food consumption may reduce the risk of allergic disease and of overweight and obesity, but the evidence is not conclusive due to likely residual confounding, as consumers of organic food tend to have healthier lifestyles overall. However, animal experiments suggest that identically composed feed from organic or conventional production impacts in different ways on growth and development. In organic agriculture, the use of pesticides is restricted, while residues in conventional fruits and vegetables constitute the main source of human pesticide exposures. Epidemiological studies have reported adverse effects of certain pesticides on children's cognitive development at current levels of exposure, but these data have so far not been applied in formal risk assessments of individual pesticides. Differences in the composition between organic and conventional crops are limited, such as a modestly higher content of phenolic compounds in organic fruit and vegetables, and likely also a lower content of cadmium in organic cereal crops. Organic dairy products, and perhaps also meats, have a higher content of omega-3 fatty acids compared to conventional products. However, these differences are likely of marginal nutritional significance. Of greater concern is the prevalent use of antibiotics in conventional animal production as a key driver of antibiotic resistance in society; antibiotic use is less intensive in organic production. Overall, this review emphasises several documented and likely human health benefits associated with organic food production, and application of such production methods is likely to be beneficial within conventional agriculture, e.g., in integrated

Cyanobacteria or blue-green algae are among the pioneer organisms of planet Earth. They developed an efficient photosynthetic capacity and played a significant role in the evolution of the early atmosphere. Essential for the development and evolution of species, they proliferate easily in aquatic environments, primarily due to human activities. Eutrophic environments are conducive to the appearance of cyanobacterial blooms that not only affect water quality, but also produce highly toxic metabolites. Poisoning and serious chronic effects in humans, such as cancer, have been described. On the other hand, many cyanobacterial genera have been studied for their toxins with anticancer potential in human cell lines, generating promising results for future research toward controlling human adenocarcinomas. This review presents the knowledge that has evolved on the topic of toxins produced by cyanobacteria, ranging from their negative impacts to their benefits. PMID:24152991

To assess the human resources impact of Malawis rapidly growing antiretroviral therapy (ART) programme and balance this against the survival benefit of health-care workers who have accessed ART themselves. We conducted a national cross-sectional survey of the human resource allocation in all public-sector health facilities providing ART in mid-2006. We also undertook a survival analysis of health-care workers who had accessed ART in public and private facilities by 30 June 2006, using data from the national ART monitoring and evaluation system. By 30 June 2006, 59 581 patients had accessed ART from 95 public and 28 private facilities. The public sites provided ART services on 2.4 days per week on average, requiring 7% of the clinician workforce, 3% of the nursing workforce and 24% of the ward clerk workforce available at the facilities. We identified 1024 health-care workers in the national ART-patient cohort (2% of all ART patients). The probabilities for survival on ART at 6 months, 12 months and 18 months were 85%, 81% and 78%, respectively. An estimated 250 health-care workers lives were saved 12 months after ART initiation. Their combined work-time of more than 1000 staff-days per week was equivalent to the human resources required to provide ART at the national level. A large number of ART patients in Malawi are managed by a small proportion of the health-care workforce. Many health-care workers have accessed ART with good treatment outcomes. Currently, staffing required for ART balances against health-care workers lives saved through treatment, although this may change in the future.

This review, commissioned by the Research Councils UK Living With Environmental Change (LWEC) programme, concerns research on the impacts on health and social care systems in the United Kingdom of extreme weather events, under conditions of climate change. Extreme weather events considered include heatwaves, coldwaves and flooding. Using a structured review method, we consider evidence regarding the currently observed and anticipated future impacts of extreme weather on health and social care systems and the potential of preparedness and adaptation measures that may enhance resilience. We highlight a number of general conclusions which are likely to be of international relevance, although the review focussed on the situation in the UK. Extreme weather events impact the operation of health services through the effects on built, social and institutional infrastructures which support health and health care, and also because of changes in service demand as extreme weather impacts on human health. Strategic planning for extreme weather and impacts on the care system should be sensitive to within country variations. Adaptation will require changes to built infrastructure systems (including transport and utilities as well as individual care facilities) and also to institutional and social infrastructure supporting the health care system. Care sector organisations, communities and individuals need to adapt their practices to improve resilience of health and health care to extreme weather. Preparedness and emergency response strategies call for action extending beyond the emergency response services, to include health and social care providers more generally.

Potential impact of fireworks on respiratory health

The world-wide use of fireworks with their consequent detrimental effect on the air quality is widely recognized with elevated ambient air levels of particulate matter and its several metallic components and gases identified in several studies carried out during such events. Exposed individuals may be at risk following inhalation of such produced pollutants. This review focuses on the impact of fireworks on air quality and the potential effect of fireworks on the respiratory system of healthy individuals as well as those suffering from underlying respiratory diseases, particularly asthma and chronic obstructive pulmonary disease (COPD). This applies not only to spectators including children but also to pyrotechnicians themselves. An extensive Medline search revealed that a strong evidence of the impact of fireworks on respiratory health is lacking in susceptible as well as healthy individuals with no formal studies on COPD or asthma, other than a few case reports in the latter. The implementation of global strategies to control the use of fireworks and hence improve air quality could possibly reduce their likely detrimental effect on human respiratory health in exposed individuals, but clearly a more targeted research is needed.

THE LOCAL IMPACTS OF MERCURY EMISSIONS FROM COAL FIRED POWER PLANTS ON HUMAN HEALTH RISK. PROGRESS REPORT FOR THE PERIOD OF MARCH 2003 - MARCH 2003.

This report presents a follow-up to previous assessments of the health risks of mercury that BNL performed for the Department of Energy. Methylmercury is an organic form of mercury that has been implicated as the form of mercury that impacts human health. A comprehensive risk assessment report was prepared (Lipfert et al., 1994) that led to several journal articles and conference presentations (Lipfert et al. 1994, 1995, 1996). In 2001, a risk assessment of mercury exposure from fish consumption was performed for 3 regions of the U.S (Northeast, Southeast, and Midwest) identified by the EPA as regions of higher impact from coal emissions (Sullivan, 2001). The risk assessment addressed the effects of in utero exposure to children through consumption of fish by their mothers. Two population groups (general population and subsistence fishers) were considered. Three mercury levels were considered in the analysis, current conditions based on measured data, and hypothetical reductions in Hg levels due to a 50% and 90% reduction in mercury emissions from coal fired power plants. The findings of the analysis suggested that a 90% reduction in coal-fired emissions would lead to a small reduction in risk to the general population (population risk reduction on the order of 10{sup -5}) and that the population risk is born by less than 1% of the population (i.e. high end fish consumers). The study conducted in 2001 focused on the health impacts arising from regional deposition patterns as determined by measured data and modeling. Health impacts were assessed on a regional scale accounting for potential percent reductions in mercury emissions from coal. However, quantitative assessment of local deposition near actual power plants has not been attempted. Generic assessments have been performed, but these are not representative of any single power plant. In this study, general background information on the mercury cycle, mercury emissions from coal plants, and risk assessment are

Atmospheric environment quality worsening is a substantial threat to public health worldwide, and in many places, air pollution due to the intensification of the human activity is increasing dramatically. However, no studies have been investigated the integration of vulnerability assessment and atmospheric environment driven by human impacts. The objective of this study was to identify and prioritize the undesirable environmental changes as an early warning system for environment managers and decision makers in term of human, atmospheric environment, and social economic elements. We conduct a vulnerability assessment method of atmospheric environment associated with human impact, this method integrates spatial context of Geographic Information System (GIS) tool, multi-criteria decision analysis (MCDA) method, ordered weighted averaging (OWA) operators under the Exposure-Sensitivity- Adaptive Capacity (ESA) framework. Decision makers can find out relevant vulnerability assessment results with different vulnerable attitudes. In the Beijing-Tianjin-Hebei (BTH) region, China, we further applied this developed method and proved it to be reliable and consistent with the China Environmental Status Bulletin. Results indicate that the vulnerability of atmospheric environment in the BTH region is not optimistic, and environment managers should do more about air pollution. Thus, the most appropriate strategic decision and development program of city or state can be picked out assisting by the vulnerable results. Copyright © 2016 Elsevier B.V. All rights reserved.
