    2017-05-16

    This work describes disposable plasma generators made from metallized paper. The fabricated plasma generators with layered and patterned sheets of paper provide a simple and flexible format for dielectric barrier discharge to create atmospheric plasma without an applied vacuum. The porosity of paper allows gas to permeate its bulk volume and fuel plasma, while plasma-induced forced convection cools the substrate. When electrically driven with oscillating peak-to-peak potentials of ±1 to ±10 kV, the paper-based devices produced both volume and surface plasmas capable of killing microbes. The plasma sanitizers deactivated greater than 99% of Saccharomyces cerevisiae and greater than 99.9% of Escherichia coli cells with 30 s of noncontact treatment. Characterization of plasma generated from the sanitizers revealed a detectable level of UV-C (1.9 nW⋅cm -2 ⋅nm -1 ), modest surface temperature (60 °C with 60 s of activation), and a high level of ozone (13 ppm with 60 s of activation). These results deliver insights into the mechanisms and suitability of paper-based substrates for active antimicrobial sanitization with scalable, flexible sheets. In addition, this work shows how paper-based generators are conformable to curved surfaces, appropriate for kirigami-like "stretchy" structures, compatible with user interfaces, and suitable for sanitization of microbes aerosolized onto a surface. In general, these disposable plasma generators represent progress toward biodegradable devices based on flexible renewable materials, which may impact the future design of protective garments, skin-like sensors for robots or prosthetics, and user interfaces in contaminated environments.

  16. Sanitation without pollution.

    Science.gov (United States)

    Winblad, U

    2000-01-01

    The most effective way of protecting drinking water resources from domestic sewage is to use technologies that do not produce sewage. This paper gives an overview of emerging alternatives in the form of ecological sanitation systems for urban and peri-urban areas. A key feature of ecological sanitation is that it regards human excreta as a resource to be recycled rather than as waste to be disposed of. Examples given include ecological sanitation systems based on dehydration and decomposition from Mexico, El Salvador, Sweden, India and Vietnam. These systems need neither water for flushing, nor pipelines for transport, nor treatment plants and arrangements for the disposal of toxic sludge. Large scale application of ecological sanitation would lead to less environmental pollution, reduced water consumption, considerable savings on sewers and treatment plants and increased employment. In addition it would provide valuable resources for food production and wasteland development.

  13. Shared sanitation: to include or to exclude?

    Science.gov (United States)

    Mara, Duncan

    2016-05-01

    Just over 600 million people used shared sanitation in 2015, but this form of sanitation is not considered 'improved sanitation' or, in the current terminology, 'basic sanitation' by WHO/UNICEF, principally because they are typically unhygienic. Recent research has shown that neighbour-shared toilets perform much better than large communal toilets. The successful development of community-designed, built and managed sanitation-and-water blocks in very poor urban areas in India should be adapted and adopted throughout urban slums in developing countries, with a caretaker employed to keep the facilities clean. Such shared sanitation should be classified as 'basic', sometimes as 'safely-managed', sanitation, so contributing to the achievement of the sanitation target of the Sustainable Development Goals. © The Author 2016.

    2009-01-01

    Basic field sanitation and hygiene is a lost art in today's modern Army. Today, more than ever, there is a need for the unit field sanitation team (FST) to serve as advisors to unit commanders in the area of basic field sanitation and hygiene. Soldiers should know how to construct field latrines, construct waste disposal devices, conduct pest management and control activities, disinfect field water supplies, and practice personal hygiene under field conditions. The current unit FST concept is centered on company-sized formations operating in open terrain. This concept does not support current operations, transformed formations, rapidly changing doctrine, and the expeditionary nature of the Army. This article does not present a new concept, but rather a new look at an existing concept and practice based upon the lessons-learned and after-action reports from the Global War on Terrorism to support the Army in transformation during an era of persistent conflict.

    Lack of access to acceptable sanitation facilities can expose individuals, particularly women, to physical, social, and mental health risks. While some of the challenges have been documented, standard metrics are needed to determine the extent to which women have urination- and defecation-related concerns and negative experiences. Such metrics also are needed to assess the effectiveness of interventions to mitigate them. We developed a sanitation insecurity measure to capture the range and frequency of women's sanitation-related concerns and negative experiences. Research was conducted in rural Odisha, India with women across various life course stages to reflect a range of perspectives. This paper documents the mixed data collection methods and the exploratory and confirmatory factor analyses we employed to arrive at a final measure. The final sanitation insecurity measure includes 50 items across seven factors that reflect the physical environment, the social environment, and individual-level constraints. Most factor scores were significantly higher for unmarried women and for women who lacked access to functional latrines, indicating social and environmental influence on experiences. This measure will enable researchers to evaluate how sanitation insecurity affects health and to determine if and how sanitation interventions ameliorate women's concerns and negative experiences associated with sanitation.

  7. Environmental Sanitation Crisis: More than just a health issue

    Directory of Open Access Journals (Sweden)

    Peter A. Harvey

    2008-01-01

    Full Text Available The global environmental sanitation crisis cannot be denied: well over a century after the sanitary revolution in 19th century Europe, 40% of the world’s population still lacks access to improved sanitation. Important lessons from the past must be applied today if the crisis is to be averted. Sanitation has suffered from a lack of prioritization for as long as it has remained the poor relation to water supply. The International Year of Sanitation 2008 provides an opportunity to separate the two and give sanitation the emphasis it requires. The economic argument for sanitation must be articulated and non-health incentives for improved sanitation exploited. Environmental sanitation results in a multitude of socio-economic benefits and can contribute positively to all the Millennium Development Goals. Community-led bottom-up approaches, rather than supply-led or technology-driven approaches, are most effective in increasing and sustaining access to sanitation but need to be implemented at scale. Targeted strategies for urban and school sanitation are also required. Evidence-based advocacy can help develop the political will that is now needed to ensure sufficient public sector investment, leadership, legislation and regulation to ensure that the fundamental human right of access to sanitation is realized.

    Full Text Available Context : A school child educated about the benefits of sanitation and good hygiene behavior is a conduit for carrying those messages far beyond the school walls, bringing lasting improvement to community hygienic practices. Aims : To study the status of school environment and sanitation in rural India. Settings and Design: Government schools in rural Karnataka, cross sectional study. Materials and Methods: Twenty schools were randomly selected for the study. Informed consent was taken from the Heads of the schools. A pre tested close ended questionnaire was used to get the information. The minimum standards for sanitation of the school and its environment in India were used as the guiding principles to evaluate the appropriateness/ adequacy of the various attributes. Statistical analysis used: Percentages and proportions. Results : Out of 20 schools selected, one fourth of the schools were located/ sited at inappropriate places. Only half of the schools had appropriate/ adequate structure. Eighteen (90% of the schools were overcrowded. Ventilation and day light was adequate for 12(60% and 14(70% of the schools respectively. Cleanliness of school compound/classrooms was adequate in 80% of the schools. There were no separate rooms for serving the midday meals in any of the schools under study. Eighteen (90% of the schools were having drinking water points. Liquid and solid waste disposal was insanitary in six (30% and eight (40% of the schools respectively. Only half of the schools had adequate latrines for boys and 60% for girls. Only two (10% of the schools had adequate hand washing points with soap. Conclusions : Environment and sanitation facilities at many of the schools are not fully satisfactory.

    2014-03-01

    Full Text Available In order to reach the Millennium Development Goals for significantly reducing the number of people without access to adequate sanitation, new holistic concepts are needed focusing on economically feasible closed-loop ecological sanitation systems rather than on expensive end-of-pipe technologies. An analysis of a former civilization in the Amazon (nowadays Brazil highlights the possibility to close the loop with a more sustainable lifestyle integrating soil fertility, food security, waste management, water protection and sanitation, renewable energy. Terra Preta do Indio is the anthropogenic black soil produced by ancient cultures through the conversion of bio-waste, fecal matter and charcoal into long-term fertile soils. These soils have maintained high amounts of organic carbon several thousand years after they were abandoned. Deriving from these concepts, Terra Preta Sanitation (TPS has been re-developed and adopted. TPS includes urine diversion, addition of a charcoal mixture and is based on lactic-acid-fermentation with subsequent vermicomposting. Lacto-fermentation is a biological anaerobic process that generates a pre-stabilization of the mixture. The main advantage of lacto-fermentation is that no gas and no odor is produced. What makes it particularly interesting for in-house systems even in urban areas. Instead, vermicomposting is an aerobic decomposition process of the pre-digested materials by the combined action of earthworms and microorganisms. It transforms the carbon and nutrients into the deep black, fertile and stable soil that can be utilized in agriculture. No water, ventilation or external energy is required. Starting from ancient Amazonian civilizations traditional knowledge, the aim of this work is to present TPS systems adopted nowadays.

  11. A conceptual model of people's approach to sanitation

    International Nuclear Information System (INIS)

    Avvannavar, Santosh M.; Mani, Monto

    2008-01-01

    Sanitation is a term primarily used to characterize the safe and sound handling (and disposal) of human excreta - or simply, people's approach to take-care of their (unavoidable) primal urge. According to the recent Human Development Report 2006 Global access to proper sanitation stands at approximately 58% with 37% being a conservative estimate both for South Asia and Sub-Saharan Africa. Various multi-million dollar sanitation programmes the world over have had little success, often due to inadequate understanding of people's sanitation approach. Sanitation approach includes the perception, feel and practices involved in satisficing the primal need to defecate and urinate (and their disposal). This paper presents a structure to understand the nature of psycho-socio-economic influences that determine societal approach to sanitation. Societies across the globe have evolved imbibing diverse influences attributed to the local environment, religion, cultural practices, war, etc. While a civilization's living environment reflects these influences in their built-environment characteristics, the influences are often deep-rooted and can be traced to the way the community members satisfice their need to defecate and urinate (sanitation approach). The objective of this paper is to trace the various approaches that diverse societies/civilizations, over time, across the world have had towards sanitation, and present a structure to articulate and understand determining factors. Sanitation also involves other domestic (solid and liquid) waste disposal but in the context of this paper the scope of sanitation has been restricted to human excreta alone. The structure presented and discussed in this paper would be useful in understanding a community better in terms of providing appropriate sanitation. It is hoped that this structure be considered as a basis for further refinement and detailed research into each of the factors determining people's sanitation approach

    2016-01-01

    Inadequate hygiene and sanitation remain leading global contributors to morbidity and mortality in children and adults. One strategy for improving sanitation access is community-led total sanitation (CLTS), in which participants are guided into self-realization of the importance of sanitation through activities called “triggering.” This qualitative study explored community members' and stakeholders' sanitation, knowledge, perceptions, and behaviors during early CLTS implementation in Zambia. We conducted 67 in-depth interviews and 24 focus group discussions in six districts in Zambia 12–18 months after CLTS implementation. Triggering activities elicited strong emotions, including shame, disgust, and peer pressure, which persuaded individuals and families to build and use latrines and handwashing stations. New sanitation behaviors were also encouraged by the hierarchical influences of traditional leaders and sanitation action groups and by children's opinions. Poor soil conditions were identified as barriers to latrine construction. Taboos, including prohibition of different generations of family members, in-laws, and opposite genders from using the same toilet, were barriers for using sanitation facilities. CLTS, through community empowerment and ownership, produced powerful responses that encouraged construction and use of latrines and handwashing practices. These qualitative data suggest that CLTS is effective for improving sanitation beliefs and behaviors in Zambia. PMID:26787149

    To assess the association of neighbourhood sanitation coverage with under-five children's diarrhoeal morbidity and to evaluate its exposure-response relationship. We used the Demographic and Health Surveys (DHS) of 29 developing countries in sub-Saharan Africa and South Asia, conducted between 2010 and 2014. The primary outcome was two-week incidence of diarrhoea in children under 5 years of age (N = 269014). We conducted three-level logistic regression analyses and applied cubic splines to assess the trend between neighbourhood-level coverage of improved household sanitation and diarrhoeal morbidity. A significant association between neighbourhood-level coverage of improved household sanitation and diarrhoeal morbidity (OR [95% CI] = 0.68 [0.62-0.76]) was found. Exposure-relationship analyses results showed improved sanitation coverage threshold at 0.6. We found marginal degree of association (OR [95% CI] = 0.82 [0.77-0.87]) below the threshold, which, beyond the threshold, sharply increased to OR of 0.44 (95% CI: 0.29-0.67) at sanitation coverage of 1 (i.e. neighbourhood-wide use of improved household sanitation). Similar exposure-response trends were identified for urban and rural subgroups. Our findings suggest that neighbourhood sanitation plays a key role in reducing diarrhoeal diseases and that increase in sanitation coverage may only have minimal impact on diarrhoeal illness, unless sufficiently high coverage is achieved. © 2017 John Wiley & Sons Ltd.

    Little research has been focused on the health status or the occupational protection awareness of sanitation workers. The policy recommendations on the occupational safety and health of sanitation workers based on the scientific research are also insufficient in developing countries like China. To study the incidence of dermatoses and the relevance with occupational exposure, protection awareness and protective measures among sanitation workers for better management and protection of the sanitation workers. 273 sanitation workers and 113 administrative staff from 11 streets of Wuhan were recruited. Dermatological problems were evaluated and recorded by physical examination. Occupational exposure, protection awareness, the use of protective equipments and personal history of skin disease were assessed by questionnaires. Compared with administrative staff, sanitation workers had much more occupational dermatological problems and had a much higher rate of harmful ultraviolet ray exposure. Young sanitation workers were more aware of occupational self-protection and a relatively higher rate of them using protective equipments compared with old ones. Exposure to multiple health hazards and the poor use of protective equipments are related to skin diseases in sanitation workers. Prejob training of self-protection and the use of protective equipments are recommended.

    The porcine gastric mucin binding magnetic bead (PGM-MB) assay was used to evaluate the ability of chlorine, chlorine dioxide, peroxyacetic acid, hydrogen peroxide, and trisodium phosphate to inactivate human norovirus within 10% stool filtrate. One-minute free chlorine treatments at concentrations of 33 and 189 ppm reduced virus binding in the PGM-MB assay by 1.48 and 4.14 log₁₀, respectively, suggesting that chlorine is an efficient sanitizer for inactivation of human norovirus (HuNoV). Five minute treatments with 5% trisodium phosphate (pH~12) reduced HuNoV binding by 1.6 log₁₀, suggesting that TSP, or some other high pH buffer, could be used to treat food and food contact surfaces to reduce HuNoV. One minute treatments with 350 ppm chlorine dioxide dissolved in water did not reduce PGM-MB binding, suggesting that the sanitizer may not be suitable for HuNoV inactivation in liquid form. However a 60-min treatment with 350 ppm chlorine dioxide did reduce human norovirus by 2.8 log₁₀, indicating that chlorine dioxide had some, albeit limited, activity against HuNoV. Results also suggest that peroxyacetic acid has limited effectiveness against human norovirus, since 1-min treatments with up to 195 ppm reduced human norovirus binding by chlorine (sodium hypochlorite) as a HuNoV disinfectant wherever possible.

    By interpreting disasters as opportunities to initiate the fulfilment of development needs, realise the vulnerability of the affected community and environment, and extend the legacy of relief funds and effort, this paper builds upon the concept linking relief, rehabilitation and development (LRRD) in the sanitation sector. It aims to use a composite of case studies to devise a framework for a semi-hypothetical scenario to identify critical components and generic processes for a LRRD action plan. The scenario is based on a latrine wetland sanitation system in a Muslim community. Several sub-frameworks are developed: (i) latrine design; (ii) assessment of human waste treatment; (iii) connective sanitation promotion strategy; and (iv) ecological systems and environmental services for sanitation and development. This scenario illustrates the complex issues involved in LRRD in sanitation work and provides technical notes and references for a legacy plan for disaster relief and development. © 2015 The Author(s).

  18. The use of detergents and sanitizers in dairy farm sanitation--an updated perspective.

    Science.gov (United States)

    Gilbert, P H

    1982-06-01

    Raw milk quality in South Africa is poor and standard plate counts in the millions per ml are common. This is largely due to inefficient cleaning and sanitizing of dairy equipment. The basic constituents in milk are described and various soils are classified as soluble in water, alkali, acid, solvent or surfactant or as insoluble. The importance of water quality is highlighted and the influence of mineral salts on soil deposition described. Dairy detergents are broadly classified as alkaline or acid, the former being most effective against fatty and proteinaceous soils and the latter effective against mineral salts. Typical detergent ingredients and their properties are described. Chlorine is incorporated into alkaline detergents not as a sanitizing agent, but as a peptizing agent to aid in protein soil removal. At high pH values the antimicrobial activity of chlorine is greatly diminished. The use of a daily acidified rinse (pH 3,0-5,0) is preferred to the periodic acid wash, since the acid rinse prevents mineral deposition rather than removing accumulated milkstone. All cleaning programmes follow the same fundamental steps--Pre-rinse (40-50 degrees C), wash (60-70 degrees C), rinse (pH 3,0-5,0) and sanitize (25 ppm iodine and 100 ppm chlorine). Farms following such a programme are able to achieve Standard Plate Counts of less than 10,000/ml and coliform counts of less than 10/ml for raw milk.

  20. Assessing Women’s Negative Sanitation Experiences and Concerns: The Development of a Novel Sanitation Insecurity Measure

    Directory of Open Access Journals (Sweden)

    Bethany A. Caruso

    2017-07-01

    Full Text Available Lack of access to acceptable sanitation facilities can expose individuals, particularly women, to physical, social, and mental health risks. While some of the challenges have been documented, standard metrics are needed to determine the extent to which women have urination- and defecation-related concerns and negative experiences. Such metrics also are needed to assess the effectiveness of interventions to mitigate them. We developed a sanitation insecurity measure to capture the range and frequency of women’s sanitation-related concerns and negative experiences. Research was conducted in rural Odisha, India with women across various life course stages to reflect a range of perspectives. This paper documents the mixed data collection methods and the exploratory and confirmatory factor analyses we employed to arrive at a final measure. The final sanitation insecurity measure includes 50 items across seven factors that reflect the physical environment, the social environment, and individual-level constraints. Most factor scores were significantly higher for unmarried women and for women who lacked access to functional latrines, indicating social and environmental influence on experiences. This measure will enable researchers to evaluate how sanitation insecurity affects health and to determine if and how sanitation interventions ameliorate women’s concerns and negative experiences associated with sanitation.

    Full Text Available As we have stated in the previous year conference paper, the human right to water and sanitation entitles everyoneto water and sanitation services which are available, accessible, affordable, acceptable and safe. Developmentprograms for water and sanitation services, as many other socio-economic development programs have often beenassumed to be neutral in terms of gender. However, sometimes there can be failures in the implementation andharnessing of such projects because of errors arising from lack of adequate integration of gender equality. In thispaper are highlighted some aspects and issues of gender mainstreaming in water supply and sanitation developmentprojects, including conclusions from a case study conducted by an NGO in a commune of Romania and ownrecommendations.

    This article demonstrates that the position of dominance enjoyed by state sanitation companies dictates the public policy decision-making process for sanitation in Brazil. These companies' hegemony is explained here through the analysis of a path that generated political and economic incentives that have permitted its consolidation over time. Through the content analysis of the legislation proposed for the sector and the material produced by the stakeholders involved in the approval of new regulations for the sector in 2007, the study identifies the main sources of incentive introduced by the adoption of the National Sanitation Plan, which explain certain structural features of the current sanitation policy and its strong capacity to withstand the innovations proposed under democratic rule.

  19. Disassembly and Sanitization of Classified Matter

    International Nuclear Information System (INIS)

    Stockham, Dwight J.; Saad, Max P.

    2008-01-01

    The Disassembly Sanitization Operation (DSO) process was implemented to support weapon disassembly and disposition by using recycling and waste minimization measures. This process was initiated by treaty agreements and reconfigurations within both the DOD and DOE Complexes. The DOE is faced with disassembling and disposing of a huge inventory of retired weapons, components, training equipment, spare parts, weapon maintenance equipment, and associated material. In addition, regulations have caused a dramatic increase in the need for information required to support the handling and disposition of these parts and materials. In the past, huge inventories of classified weapon components were required to have long-term storage at Sandia and at many other locations throughout the DoE Complex. These materials are placed in onsite storage unit due to classification issues and they may also contain radiological and/or hazardous components. Since no disposal options exist for this material, the only choice was long-term storage. Long-term storage is costly and somewhat problematic, requiring a secured storage area, monitoring, auditing, and presenting the potential for loss or theft of the material. Overall recycling rates for materials sent through the DSO process have enabled 70 to 80% of these components to be recycled. These components are made of high quality materials and once this material has been sanitized, the demand for the component metals for recycling efforts is very high. The DSO process for NGPF, classified components established the credibility of this technique for addressing the long-term storage requirements of the classified weapons component inventory. The success of this application has generated interest from other Sandia organizations and other locations throughout the complex. Other organizations are requesting the help of the DSO team and the DSO is responding to these requests by expanding its scope to include Work-for- Other projects. For example

    Bubenheim, David L.

    2013-01-01

    In rural Alaskan communities personal health is threatened by energy costs and limited access to clean water, wastewater management, and adequate nutrition. Fuel-­-based energy systems are significant factors in determining local accessibility to clean water, sanitation and food. Increasing fuel costs induce a scarcity of access and impact residents' health. The University of Alaska Fairbanks (UAF) School of Natural Resources and Agricultural Sciences (SNRAS), NASA's Ames Research Center, and USDA Agricultural Research Service (ARS) have joined forces to develop high-efficiency, low­-energy consuming techniques for water treatment and food production in rural circumpolar communities. Methods intended for exploration of space and establishment of settlements on the Moon or Mars will ultimately benefit Earth's communities in the circumpolar north. The initial phase of collaboration is completed. Researchers from NASA Ames Research Center and SNRAS, funded by the USDA­-ARS, tested a simple, reliable, low-energy sewage treatment system to recycle wastewater for use in food production and other reuse options in communities. The system extracted up to 70% of the water from sewage and rejected up to 92% of ions in the sewage with no carryover of toxic effects. Biological testing showed that plant growth using recovered water in the nutrient solution was equivalent to that using high-purity distilled water. With successful demonstration that the low energy consuming wastewater treatment system can provide safe water for communities and food production, the team is ready to move forward to a full-scale production testbed. The SNRAS/NASA team (including Alaska students) will design a prototype to match water processing rates and food production to meet rural community sanitation needs and nutritional preferences. This system would be operated in Fairbanks at the University of Alaska through SNRAS. Long­-term performance will be validated and operational needs of the

    Local governments in both Mexico and the U.S. spend considerable money on public services, which do not always bring the expected results. For instance, a large part of the public budget is destined to solve social and health problems, such as public sanitation. Government has attacked the problem by providing public sanitation infrastructure (such as garbage and recycling receptacles) and by using social ad campaigns. However, these efforts do not always affect the habits of residents and bring the desired changes in city sanitation. This article presents a case study that used a participatory method to address an innovative city sanitation effort: The Clean City Program in Puebla, Mexico. This program adopted social marketing techniques, a discipline born in the 70s when the principles and practices developed to sell products and services started to be applied to sell ideas, attitudes, or behaviors. Social marketing programs have been adopted by governments to change attitudes and behavior in areas such as public services. The article first describes the context and strategies of the program, which included the use of the promotora model to engage community members. The researchers then make use of qualitative data gathered throughout program planning and implementation to evaluate the impact of the social marketing programs and its effectiveness. The article analyzes social, educational, economic, demographic, and cultural factors that influence the effectiveness of sanitation programs and presents recommendations for strategies to engage community members in community sanitation programs.

    Cure, Laila; Van Enk, Richard

    2015-09-01

    Hand hygiene is the most important intervention to prevent infection in hospitals. Health care workers should clean their hands at least before and after contact with patients. Hand sanitizer dispensers are important to support hand hygiene because they can be made available throughout hospital units. The aim of this study was to determine whether the usability of sanitizer dispensers correlates with compliance of staff in using the sanitizer in a hospital. This study took place in a Midwest, 404-bed, private, nonprofit community hospital with 15 inpatient care units in addition to several ambulatory units. The usability and standardization of sanitizers in 12 participating inpatient units were evaluated. The hospital measured compliance of staff with hand hygiene as part of their quality improvement program. Data from 2010-2012 were analyzed to measure the relationship between compliance and usability using mixed-effects logistic regression models. The total usability score (P = .0046), visibility (P = .003), and accessibility of the sanitizer on entrance to the patient room (P = .00055) were statistically associated with higher observed compliance rates. Standardization alone showed no significant impact on observed compliance (P = .37). Hand hygiene compliance can be influenced by visibility and accessibility of dispensers. The sanitizer location should be part of multifaceted interventions to improve hand hygiene. Copyright © 2015 Association for Professionals in Infection Control and Epidemiology, Inc.

These methods were investigated by undertaking small scale field trials with pit latrine sludge in Blantyre, Malawi. Hydrated lime was able to reduce the E. coli count in the sludge to below the detectable limit within 1 h applying a pH > 11 (using a dosage from 7% to 17% w/w, depending faecal sludge alkalinity), urea treatment required about 4 days using 2.5% wet weight urea addition, and lactic acid fermentation needed approximately 1 week after being dosed with 10% wet weight molasses (2 g (glucose/fructose)/kg) and 10% wet weight pre-culture (99.8% pasteurised whole milk and 0.02% fermented milk drink containing Lactobacillus casei Shirota). Based on Malawian prices, the cost of sanitizing 1 m³ of faecal sludge was estimated to be €32 for lactic acid fermentation, €20 for urea treatment and €12 for hydrated lime treatment.

    Several studies have indicated a connection between handwashing and illness-related absenteeism in school settings. The difficulty of ensuring consistent and effective handwashing among student populations has also been noted. The purpose of this study was to assess the effectiveness of the use of an alcohol gel hand sanitizer in the classroom to help decrease the illness-related absentee rate for elementary school students. This study involved 5 individual school districts, 16 individual schools, and more than 6000 students in Delaware, Ohio, Tennessee, and California. Individual schools in each district were paired into product and control groups. In the product group schools, an alcohol gel hand sanitizer was used by the students and staff when entering and leaving the classroom. Absenteeism due to infection was recorded, and the data were statistically analyzed. The overall reduction in absenteeism due to infection in the schools included in this study was 19.8% for schools that used an alcohol gel hand sanitizer compared with the control schools (P sanitizer was used. Elementary school absenteeism due to infection is significantly reduced when an alcohol gel hand sanitizer is used in the classroom as part of a hand hygiene program.

    To increase the community participation in the toilet sanitation management at house to making a house according the healthy house standart. The toilet sanitation management is becoming complex with increasing population growth, and limited land for sanitation. The community participation determines the success of the toilet sanitation management and improving the health status of the community. This study used an observation method for the availability of latrines according the healthy house criteria, spatial layout and pit layout that meet health and safety standards. Spatial and layout include bathroom area, type of material used for wall and floor bathroom, type of latrine, distance the waste storage distance with water source, and sewerage. The respondents in this study are the people who live in Jaten Village taken by accidental sampling. The number of respondents in this study were 15 respondents.This study shows that all respondents (100%) already have toilet and 8 respondents (53%) have a good toilet sanitation management. Respondents have provided latrines as an effort to manage household waste and according the healthy house standart. The latrine spatial plan has been well implemented, but the latrine layout plan has not been properly.

    Demand for adequate provision of drinking-water and sanitation facilities to promote public health and economic growth is increasing in the rapidly urbanizing countries of the developing world. With a panel of data on Asia and Africa from 1990 to 2008, associations are estimated between the occurrence of cholera outbreaks, the case rates in given outbreaks, the mortality rates associated with cholera and two disease control mechanisms, drinking-water and sanitation services. A statistically significant and negative effect is found between drinking-water services and both cholera case rates as well as cholera-related mortality rates. A relatively weak statistical relationship is found between the occurrence of cholera outbreaks and sanitation services.

  10. Preventing SQL Injection through Automatic Query Sanitization with ASSIST

    Full Text Available Web applications are becoming an essential part of our everyday lives. Many of our activities are dependent on the functionality and security of these applications. As the scale of these applications grows, injection vulnerabilities such as SQL injection are major security challenges for developers today. This paper presents the technique of automatic query sanitization to automatically remove SQL injection vulnerabilities in code. In our technique, a combination of static analysis and program transformation are used to automatically instrument web applications with sanitization code. We have implemented this technique in a tool named ASSIST (Automatic and Static SQL Injection Sanitization Tool for protecting Java-based web applications. Our experimental evaluation showed that our technique is effective against SQL injection vulnerabilities and has a low overhead.

We present the case of a 50-year-old woman who was admitted with acute alcohol intoxication and had near complete recovery in 12 hrs. Subsequently, she was found unresponsive on the floor of her hospital room on two separate occasions. Evaluations revealed repeatedly elevated levels of ethanol, acetone, and lactate as well as increased anion gap and hypotension, requiring intensive care unit evaluation and intubation for airway protection. During the second episode, she was found next to an empty bottle of ethanol-based hospital hand sanitizer. She confirmed ingesting hand sanitizer in order to become intoxicated.

    2013-01-01

    Data mining is used to extract useful information hidden in the data. Sometimes this extraction of information leads to revealing sensitive information. Privacy preservation in Data Mining is a process of sanitizing sensitive information. This research focuses on sanitizing sensitive rules discovered in quantitative data. The proposed scheme, Privacy Preserving in Fuzzy Association Rules (PPFAR) is based on fuzzy correlation analysis. In this work, fuzzy set concept is integrated with fuzzy correlation analysis and Apriori algorithm to mark interesting fuzzy association rules. The identified rules are called sensitive. For sanitization, we use modification technique where we substitute maximum value of fuzzy items with zero, which occurs most frequently. Experiments demonstrate that PPFAR method hides sensitive rules with minimum modifications. The technique also maintains the modified data's quality. The PPFAR scheme has applications in various domains e.g. temperature control, medical analysis, travel time prediction, genetic behavior prediction etc. We have validated the results on medical dataset.

    Colonization of wounds with multidrug-resistant organisms is a difficult orthopedic problem. Acinetobacter infections are especially difficult because they are resistant to all currently available antibiotics. We present the use of a novel skin sanitizer, Stay Byotrol Clean (Byotrol Inc, Spartanburg, South Carolina), to treat a multidrug-resistant wound infection. A 31-year-old T10 paraplegic man presented with chronic bilateral stage IV decubitus trochanteric ulcers. Cultures grew methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus. The ulcers were initially treated with irrigation and debridement and vancomycin, levaquin, and cefepime. After 4 months of aggressive treatment, the cultures continued to be positive for Escherichia coli and Acinetobacter baumannii. The patient was started on amikacin and tigecycline. Despite 1 additional month of aggressive wound care, debridements, and intravenous antibiotics, the cultures continued to grow A baumannii and Pseudomonas aerug. The A baumannii was resistant to all available antibiotics tested. The ulcers were then treated with daily application of Stay Byotrol Clean hand and skin sanitizer. Four days later, cultures were negative for any bacterial growth, with no A baumannii. After 1 week, the ulcers showed new granulation tissue with no visible necrotic tissue. After 3 months of treatment, the ulcers had healed. Stay Byotrol Clean is nonirritating and contains no iodine or alcohol. It is currently being used for decolonization of patients on admission to the hospital, however, there is great potential for its use in wound treatment, preoperative surgical sterilization, and orthopedic devices.

  17. Does global progress on sanitation really lag behind water? An analysis of global progress on community- and household-level access to safe water and sanitation.

    Science.gov (United States)

    Cumming, Oliver; Elliott, Mark; Overbo, Alycia; Bartram, Jamie

    2014-01-01

    Safe drinking water and sanitation are important determinants of human health and wellbeing and have recently been declared human rights by the international community. Increased access to both were included in the Millennium Development Goals under a single dedicated target for 2015. This target was reached in 2010 for water but sanitation will fall short; however, there is an important difference in the benchmarks used for assessing global access. For drinking water the benchmark is community-level access whilst for sanitation it is household-level access, so a pit latrine shared between households does not count toward the Millennium Development Goal (MDG) target. We estimated global progress for water and sanitation under two scenarios: with equivalent household- and community-level benchmarks. Our results demonstrate that the "sanitation deficit" is apparent only when household-level sanitation access is contrasted with community-level water access. When equivalent benchmarks are used for water and sanitation, the global deficit is as great for water as it is for sanitation, and sanitation progress in the MDG-period (1990-2015) outstrips that in water. As both drinking water and sanitation access yield greater benefits at the household-level than at the community-level, we conclude that any post-2015 goals should consider a household-level benchmark for both.

    Full Text Available This project was developed during a three month internship with Habitat for Humanity Vietnam (HFHV supported by the Royal Melbourne Institute of Technology (RMIT Engineers Without Borders Australia (EWB Development Scholarship for 2010/2011. During discussions with HFHV staff, several areas of concern with regards to sanitation and hygiene practices in rural Kien Giang Province were raised. These included the widespread use of drop toilets over waterways, poor hygiene practices in impoverished households and in schools, lack of sanitation options for HFHV construction programmes and no facilities for emptying existing septic tanks of accumulated sludge. This article evaluates existing sanitation technologies for introduction into HFHV’s construction programme in Kien Giang Province. It was determined that for onsite disposal of sanitation system products, the double dehydration vault, the composting chamber and the urine collection tank were appropriate technologies. Pit latrines or variations thereof were deemed inappropriate because of the high watertables. Anaerobic reactor systems were deemed inappropriate as they accumulate pathogenic sludge and effluent for which there is currently no appropriate treatment that meets the project design criteria. As onsite disposal system demand may be low due to cultural and social taboos, an investigation and discussion into offsite treatment was also undertaken. It was determined that a co-composting facility would be the most appropriate offsite treatment technology.

  3. Hygiene and sanitation requirements in Danish biogas plants

    Energy Technology Data Exchange (ETDEWEB)

    1997-08-01

    According to Danish regulations, systematic pathogen reducing treatment is required, when industrial by-products and waste products, and urban waste, ie garbage from households and sewage sludge, are processed, before being used - without restrictions - as fertilizers on agricultural land. An adequate pathogen reducing effect (PRE) can be achieved in the digestion tanks and sanitation tanks of the biogas plants, provided they are operated correctly and respect the criteria of the official requirements. The FS-method is a microbiological indicator method based on faecal streptococci (enterococci) (FS). It may be used to check the sanitation effect achieved by the treatment in a tank. The effect is expressed numerically by the log{sub 10}-reduction of the numbers of FS measured in the biomass before and after treatment. The PRE was examined in 10 large-scale biogas plants during a period of 2-3 years. It was demonstrated that properly directed and well-functioning thermophilic digestion tanks ensure the removal of most pathogenic microorganisms from organic waste and slurry. The removal of pathogens by the treatment in mesophilic digestion tanks is incomplete. Systematic studies of the processes of inactivation of bacteria and virus in slurry and in animal tissues gave evidence that the PRE is enhanced in the microbiological environment of thermophilic digestion tanks. The sanitation criteria, ie combinations of temperature/time, for the processing of biomass in digestion tanks and sanitation tanks in biogas plants are specified. (au) 19 refs.

    Analysis of relationships among national wealth, access to improved water supply and sanitation facilities, and population health indices suggests that the adequacy of water resources at the national level is a poor predictor of economic development--namely, that low water stress is neither necessary nor sufficient for economic development at the present state of water stress among Pacific Rim nations. Although nations differ dramatically in terms of priority provided to improved water and sanitation, there is some level of wealth (per capita GNP) at which all nations promote the development of essential environmental services. Among the Pacific Rim countries for which there are data, no nation with a per capita GNP > US$18,000 per year has failed to provide near universal access to improved water supply and sanitation. Below US$18,000/person-year, however, there are decided differences in the provision of sanitary services (improved water supply and sanitation) among nations with similar economic success. There is a fairly strong relationship between child mortality/life expectancy and access to improved sanitation, as expected from the experiences of developed nations. Here no attempt is made to produce causal relationships among these data. Failure to meet Millennium Development Goals for the extension of improved sanitation is frequently evident in nations with large rural populations. Under those circumstances, capital intensive water and sanitation facilities are infeasible, and process selection for water/wastewater treatment requires an adaptation to local conditions, the use of appropriate materials, etc., constraints that are mostly absent in the developed world. Exceptions to these general ideas exist in water-stressed parts of developed countries, where water supplies are frequently augmented by water harvesting, water reclamation/reuse, and the desalination of brackish water resources. Each of these processes involves public acceptance of water

    2011-07-01

    The need for sustainable systems is apparent as climate change and other adverse anthropogenic activities continue to negatively affect the soil fertility in Africa. One of the indicators of the loss of soil fertility is the continuous decrease in soil organic matter, which is the major building block of a fertile soil. This is mainly attributed to the inappropriate practice of human-beings of taking more substances from the ecosystem than the amount replaced. As the soil fertility is increasingly lost, food insecurity, due to dropped productivity of the soil, is becoming a critical issue in many areas of Africa, Tanzania is not any different in this respect. On the other hand, most people in rural areas of Africa still lack possibilities to cover their daily energy needs in a more sustainable way and many people mainly rely on firewood. This, in turn, has an adverse impact on the climate and the soil, causing a local viscous circle of poor soil and productivity conditions. Moreover, the sanitation coverage of those areas is very low and there is a need for appropriate sanitation systems. Therefore, the aim of this project is, to conduct research on the possibility of establishing a self-sustaining system for the rural areas of Kagera, Tanzania, to address the three basic issues: sanitation, energy supply and soil fertility. The system consists of a small-scale biogas digester, a urine diverting dehydrating toilet (UDDT) and an adaptive hydrothermal carbonization (HTC) unit. Biogas is produced from crop residues and other domestic organic waste. The fermentation residues and the dehydrated fecal matter from the UDDT is then treated with HTC. The carbonised and sanitized residue is then applied as soil amendment to improve the soil fertility as manifested by the Terra Preta in the Amazon. This holistic approach is a new development in ecological sanitation. Therefore, a comprehensive sustainability assessment including environmental, economic and socio

    This paper presents the results of a mixed-methods study examining adaptation strategies that property owners in low-income, rapidly urbanizing areas in Malawi adopt to address the limitations of pit latrines, the most common method of disposing human excreta. A particular challenge is lack of space for constructing new latrines as population density increases: traditional practice has been to cap full pits and simply move to a new site, but increasing demands on space require new approaches to extend the service life of latrines. In this context, we collected data on sanitation technology choices from January to September 2013 through 48 in-depth interviews and a stated preference survey targeting 1,300 property owners from 27 low-income urban areas. Results showed that property owners with concern about space for replacing pit latrines were 1.8 times more likely to select pit emptying service over the construction of new pit latrines with a slab floor (p = 0.02) but there was no significant association between concern about space for replacing pit latrines and intention to adopt locally promoted, novel sanitation technology known as ecological sanitation (ecosan). Property owners preferred to adapt existing, known technology by constructing replacement pit latrines on old pit latrine locations, reducing the frequency of replacing pit latrines, or via emptying pit latrines when full. This study highlights potential challenges to adoption of wholly new sanitation technologies, even when they present clear advantages to end users. To scale, alternative sanitation technologies for rapidly urbanising cities should offer clear advantages, be affordable, be easy to use when shared among multiple households, and their design should be informed by existing adaptation strategies and local knowledge.

  1. Towards “Sustainable” Sanitation: Challenges and Opportunities in Urban Areas

    Full Text Available While sanitation is fundamental for health and wellbeing, cities of all sizes face growing challenges in providing safe, affordable and functional sanitation systems that are also sustainable. Factors such as limited political will, inadequate technical, financial and institutional capacities and failure to integrate safe sanitation systems into broader urban development have led to a persistence of unsustainable systems and missed opportunities to tackle overlapping and interacting urban challenges. This paper reviews challenges associated with providing sanitation systems in urban areas and explores ways to promote sustainable sanitation in cities. It focuses on opportunities to stimulate sustainable sanitation approaches from a resource recovery perspective, generating added value to society while protecting human and ecosystem health. We show how, if integrated within urban development, sustainable sanitation has great potential to catalyse action and contribute to multiple sustainable development goals.

    Universal precautions require that perioperative health care personnel wash their hand before and after all patient contact. Time constraints, however, can make adhering to universal precautions, including proper hand washing, difficult. Some perioperative health care workers, therefore, routinely use rise-free hand sanitizers to supplement normal hand washing. This study evaluated immediate and persistent antimicrobial effectiveness of two alcohol--containing hand sanitizers and a novel surfactant, allantoin, benzalkonium chloride (SAB) hand sanitizer using a federally approved effectiveness protocol. Results indicate that all three products were equally effective after a single application. After repeated use, the alcohol-containing sanitizers did not meet federal performance standards, and the alcohol-free sanitizer did. These properties and others illustrated in this article indicate that the nonflammable, alcohol-free SAB hand sanitizer is the most favorable of the rise-free hand sanitizer formulas for normal hand washing.

    ABSTRACT The use of sanitizers is essential for produce safety. However, little is known about how sanitizer efficacy varies with respect to the chemical surface properties of produce. To answer this question, the disinfection efficacies of an oxidant-based sanitizer and a new surfactant-based sanitizer for porcine rotavirus (PRV) strain OSU were examined. PRV was attached to the leaf surfaces of two kale cultivars with high epicuticular wax contents and one cultivar of endive with a low epicuticular wax content and then treated with each sanitizer. The efficacy of the oxidant-based sanitizer correlated with leaf wax content as evidenced by the 1-log10 PRV disinfection on endive surfaces (low wax content) and 3-log10 disinfection of the cultivars with higher wax contents. In contrast, the surfactant-based sanitizer showed similar PRV disinfection efficacies (up to 3 log10) that were independent of leaf wax content. A statistical difference was observed with the disinfection efficacies of the oxidant-based sanitizer for suspended and attached PRV, while the surfactant-based sanitizer showed similar PRV disinfection efficacies. Significant reductions in the entry and replication of PRV were observed after treatment with either disinfectant. Moreover, the oxidant-based-sanitizer-treated PRV showed sialic acid-specific binding to the host cells, whereas the surfactant-based sanitizer increased the nonspecific binding of PRV to the host cells. These findings suggest that the surface properties of fresh produce may affect the efficacy of virus disinfection, implying that food sanitizers should be carefully selected for the different surface characteristics of fresh produce. IMPORTANCE Food sanitizer efficacies are affected by the surface properties of vegetables. This study evaluated the disinfection efficacies of two food sanitizers, an oxidant-based sanitizer and a surfactant-based sanitizer, on porcine rotavirus strain OSU adhering to the leaf epicuticular surfaces of

  5. The Role of Perceived Social Norms in Rural Sanitation: An Explorative Study from Infrastructure-Restricted Settings of South Ethiopia.

    The perception of social sanitation norms (PSSNs) around unacceptability of open defecation has been a key aspect of recent sanitation interventions. However, underlying mechanisms through which "reconstructed" PSSNs affect sanitation outcomes have been a black box. This explorative cross-sectional study examines direct and indirect links between PSSNs and sanitation safety using data from structured interviews and observations in 368 households in rural South Ethiopia. In addition to a positive association between PSSNs and sanitation safety, we propose and examine the following two mechanisms: First, we confirm a potentially adverse feedback of PSSNs on future sanitation safety by enhancing the emotional satisfaction with current sanitation practice (satisfaction independent of the functionality of sanitation facilities). Second, inspired by the social amplification/attenuation of risk framework, we demonstrate that PSSNs work as a "social filter" that can amplify or attenuate the effects of other variables targeted in sanitation interventions such as perceived health-related and non-health risks and benefits associated with open defecation and private latrine ownership, respectively, and factual hygiene and sanitation knowledge. These findings imply that PSSNs are not only important per se, but they are also important instrumentally because sanitation outcomes depend upon the capacity of social influences to shape the perception of sanitation risks and benefits and sanitation-related awareness in desirable ways. The mechanisms outlined in this paper as well as the sustainability of sanitation outcomes depend on whether and how social sanitation norms are internalized.

  6. Why do households invest in sanitation in rural Benin: Health, wealth, or prestige?

    Gross, Elena; Günther, Isabel

    2014-10-01

    Seventy percent of the rural population in sub-Saharan Africa does not use adequate sanitation facilities. In rural Benin, as much as 95% of the population does not use improved sanitation. By analyzing a representative sample of 2000 rural households, this paper explores why households remain without latrines. Our results show that wealth and latrine prices play the most decisive role for sanitation demand and ownership. At current income levels, sanitation coverage will only increase to 50% if costs for construction are reduced from currently 190 USD to 50 USD per latrine. Our analysis also suggests that previous sanitation campaigns, which were based on prestige and the allure of a modern lifestyle as motives for latrine construction, have had no success in increasing sanitation coverage. Moreover, improved public health, which is the objective of public policies promoting sanitation, will not be effective at low sanitation coverage rates. Fear at night, especially of animals, and personal harassment, are stated as the most important motivational factors for latrine ownership and the intention to build one. We therefore suggest changing the message of sanitation projects and introduce new low-cost technologies into rural markets; otherwise, marketing strategies will continue to fail in increasing sanitation demand.

    The article explores the intersection between child rights, water scarcity, sanitation, and the human security paradigm. The recognition of child rights has been advanced through the 1989 Convention on the Rights of the Child and other international legal instruments, while water rights are increasingly affirmed in international law and through the historic July 2010 United Nations General Assembly resolution that strengthened the legal foundation for water security and human rights. Yet there remains a development gap in terms of child access to clean and secure water sources for basic human development needs. The human security paradigm provides a legal and humanitarian foundation for the extension of child rights related to water and sanitation. Copyright © 2012 Pink.

Two sanitizing solutions were employed: sodium hypochlorite (SH and propolis (PS, during 15 and 30 min. Tap water (TW was used as a control. Regarding the mean reduction on aerobic mesophiles, psychrotrophic and fecal coliforms, the SH and PS treatments showed the same pattern of variation. In all cases, PS was slightly more effective in the microbiological reduction in comparison with commercial SH. Reductions between two and three log cycles were obtained with PS on aerobic mesophiles and psychrotrophic counts. The information obtained in the present study can be used to evaluate the potential use of propolis as product for sanitizing other vegetables and for developing other food preservation technologies, with impact on human health.

    Kenya has undergone rapid urbanization as people migrate to the cities in search of economic opportunities. This has given rise to informal settlements characterized by overcrowding, poor infrastructure, and inadequate social amenities. A cross-sectional study on water, sanitation, and hygiene (WASH) status was carried out in Mathare, an informal settlement in Nairobi. A random sample of 380 households was used. The average household size was five people, and 26% of the household heads had completed secondary or higher level of education. The main source of income (70%) was self-employment with 41% of the households living on less than 1.5 USD per day. The WASH situation in the urban slums is below the minimum standard recommended by the World Health Organization (WHO). There is need to improve the situation by improving and installing basic infrastructure including water, sanitation, and solid waste collection.

  11. Incentivizing Decentralized Sanitation: The Role of Discount Rates.

    2016-06-21

    In adoption decisions for decentralized sanitation technologies, two decision makers are involved: the public utility and the individual homeowner. Standard life cycle cost is calculated from the perspective of the utility, which uses a market-based discount rate in these calculations. However, both decision-makers must be considered, including their differing perceptions of the time trade-offs inherent in a stream of costs and benefits. This study uses the discount rate as a proxy for these perceptions and decision-maker preferences. The results in two case studies emphasize the dependence on location of such analyses. Falmouth, Massachusetts, appears to be a good candidate for incentivizing decentralized sanitation while the Allegheny County Sanitary Authority service area in Pennsylvania appears to have no need for similar incentives. This method can be applied to any two-party decision in which the parties are expected to have different discount rates.

    2014-04-01

    Full Text Available OBJECTIVES: to evaluate the handling and risk factors for poisoning and/or digestive tract injuries associated with the use of sanitizing products at home. METHODS: interviews were conducted in 419 households from different regions, collecting epidemiological data from residents and risk habits related to the use and storage of cleaning products. RESULTS: sanitizing products considered to be a health risk were found in 98% of the households where the research was conducted, and in 54% of cases, they were stored in places easily accessible to children. Lye was found in 19%, followed by illicit products in 39% of homes. In 13% of households, people produced soap, and in 12% they stored products in non-original containers. The use of illicit products and the manufacture of handmade soap were associated with lower educational level of the household owners and with the regions and socioeconomic classes with lower purchasing power. CONCLUSIONS: risk practices such as inadequate storage, manufacturing, and use of sanitizing products by the population evidence the need for public health policies, including educational measures, as a means of preventing accidents.

    In June 1978, there occurred in the port of Ijmuiden, Netherlands, a contamination incident involving drums originating from Switzerkand and containing radioactive wastes intended to be dumped into the sea. The batch of 207 drums excluded from the sea-dumping action had to be sanitated for the next year dumping in such a manner, that these wastes met the international requirements and could be disposed of by sinking them into the Atlantic. As a consequence of extensive sanitation work, requiring part of the wastes to be newly conditioned and several drums to be packaged again, the total weight of the wastes ready for dumping was doubled. The total radiation exposure for the personnel that took part in the individual phases of sanitation amounted to about 10 man-rem. The main causes for this contamination incident were unusual chemical composition of the concentrate to be solidified, unsufficient quality control and a position not suitabble for transport. The measures taken after this incident intend to avoid similar occurrences in the future. (orig.) [de

    The practice of sharing sanitation facilities does not meet the current World Health Organization/UNICEF definition for what is considered improved sanitation. Recommendations have been made to categorize shared sanitation as improved sanitation if security, user access, and other conditions can be assured, yet limited data exist on user preferences with respect to shared facilities. This study analyzed user perceptions of shared sanitation facilities in rural households in East Java, Indonesia, and Bangladesh. Cross-sectional studies of 2,087 households in East Java and 3,000 households in Bangladesh were conducted using questionnaires and observational methods. Relative risks were calculated to analyze associations between sanitation access and user perceptions of satisfaction, cleanliness, and safety. In East Java, 82.4% of households with private improved sanitation facilities reported feeling satisfied with their place of defecation compared to 68.3% of households with shared improved facilities [RR 1.19, 95% CI 1.09, 1.31]. In Bangladesh, 87.7% of households with private improved facilities reported feeling satisfied compared to 74.5% of households with shared improved facilities [RR 1.15, 95% CI 1.10, 1.20]. In East Java, 79.5% of households who reported a clean latrine also reported feeling satisfied with their place of defecation; only 38.9% of households who reported a dirty latrine also reported feeling satisfied [RR 1.74, 95% CI 1.45, 2.08]. Simple distinctions between improved and unimproved sanitation facilities tend to misrepresent the variability observed among households sharing sanitation facilities. Our results suggest that private improved sanitation is consistently preferred over any other sanitation option. An increased number of users appeared to negatively affect toilet cleanliness, and lower levels of cleanliness were associated with lower levels of satisfaction. However, when sanitation facilities were clean and shared by a limited number

    Hand sanitizers have seen a rapid increase in popularity amongst the general population and this increased use has led to the belief that hand sanitizers may have an effect on subsequent fingermark detection. Based on this hypothesis, three alcoholic and two non-alcoholic hand sanitizers were evaluated to determine the effect they had on the detection of fingermarks deposited after their use. The following fingermark detection methods were applied: 1,2-indanedione-zinc, ninhydrin, physical developer (porous substrate); and cyanoacrylate, rhodamine 6G, magnetic powder (non-porous substrate). Comparison between hand sanitized fingermarks and non-hand sanitized fingermarks showed that the alcohol-based hand sanitizers did not result in any visible differences in fingermark quality. The non-alcoholic hand sanitizers, however, improved the quality of fingermarks developed with 1,2-indanedione-zinc and ninhydrin, and marginally improved those developed with magnetic powder. Different parameters, including time since hand sanitizer application prior to fingermark deposition and age of deposited mark, were tested to determine the longevity of increased development quality. The non-alcoholic hand sanitized marks showed no decrease in quality when aged for up to two weeks. The time since sanitizer application was determined to be an important factor that affected the quality of non-alcoholic hand sanitized fingermarks. It was hypothesized that the active ingredient in non-alcoholic hand sanitizers, benzalkonium chloride, is responsible for the increase in fingermark development quality observed with amino acid reagents, while the increased moisture content present on the ridges resulted in better powdered fingermarks.

    Sanitation is a term primarily used to characterize the safe and sound handling (and disposal) of human excreta - or simply, people's approach to take-care of their (unavoidable) primal urge. According to the recent Human Development Report 2006 Global access to proper sanitation stands at approximately 58% with 37% being a conservative estimate both for South Asia and Sub-Saharan Africa. Various multi-million dollar sanitation programmes the world over have had little success, often due to inadequate understanding of people's sanitation approach. Sanitation approach includes the perception, feel and practices involved in satisficing the primal need to defecate and urinate (and their disposal). This paper presents a structure to understand the nature of psycho-socio-economic influences that determine societal approach to sanitation. Societies across the globe have evolved imbibing diverse influences attributed to the local environment, religion, cultural practices, war, etc. While a civilization's living environment reflects these influences in their built-environment characteristics, the influences are often deep-rooted and can be traced to the way the community members satisfice their need to defecate and urinate (sanitation approach). The objective of this paper is to trace the various approaches that diverse societies/civilizations, over time, across the world have had towards sanitation, and present a structure to articulate and understand determining factors. Sanitation also involves other domestic (solid and liquid) waste disposal but in the context of this paper the scope of sanitation has been restricted to human excreta alone. The structure presented and discussed in this paper would be useful in understanding a community better in terms of providing appropriate sanitation. It is hoped that this structure be considered as a basis for further refinement and detailed research into each of the factors determining people's sanitation

    Emerging evidence demonstrates how inadequate access to water and sanitation is linked to psychosocial stress, especially among women, forcing them to navigate social and physical barriers during their daily sanitation routines. We examine sanitation-related psychosocial stress (SRPS) across women's reproductive lives in three distinct geographic sites (urban slums, rural villages, and rural tribal villages) in Odisha, India. We explored daily sanitation practices of adolescent, newly married, pregnant, and established adult women (n = 60) and identified stressors encountered during sanitation. Responding to structured data collection methods, women ranked seven sanitation activities (defecation, urination, menstruation, bathing, post-defecation cleaning, carrying water, and changing clothes) based on stress (high to low) and level of freedom (associated with greatest freedom to having the most restrictions). Women then identified common stressors they encountered when practicing sanitation and sorted stressors in constrained piles based on frequency and severity of each issue. The constellation of factors influencing SRPS varies by life stage and location. Overall, sanitation behaviors that were most restricted (i.e., menstruation) were the most stressful. Women in different sites encountered different stressors, and the level of perceived severity varied based on site and life stage. Understanding the influence of place and life stage on SRPS provides a nuanced understanding of sanitation, and may help identify areas for intervention.

    To define prognostic criteria of efficacy of programmed laparoscopic sanitation of the abdominal cavity in peritonitis. There were 32 patients after programmed laparoscopic sanitation of abdominal cavity for peritonitis due to different acute surgical diseases. Subsequently 12 of them required relaparotomy due to poor effectiveness of laparoscopic sanitation. Comprehensive clinical examination and laboratory assessment of some indexes of homeostasis and oxidative status were conducted. Prognostic clinical and laboratory criteria of efficacy of laparoscopic abdominal sanitation were suggested after analysis of intraoperative data during primary surgery and laboratory values in the 1st postoperative day. The offered prognostic criteria allow to define further management of peritonitis patients after primary laparotomy.

    Produce safety has received much recent attention, with the emphasis being largely on discovery of how microbes invade produce. However, the sanitization operation deserves more attention than it has received. The ability of a sanitizer to reach the site of pathogens is a fundamental prerequisite for efficacy. This work addresses the transport processes of ozone (gaseous and liquid) sanitizer for decontamination of leafy greens. The liquid sanitizer was ineffective against Escherichia coli K-12 in situations where air bubbles may be trapped within cavities. A model was developed for diffusion of sanitizer into the interior of produce. The reaction rate of ozone with the surface of a lettuce leaf was determined experimentally and was used in a numerical simulation to evaluate ozone concentrations within the produce and to determine the time required to reach different locations. For aqueous ozone, the penetration depth was limited to several millimeters by ozone self-decomposition due to the significant time required for diffusion. In contrast, gaseous sanitizer was able to reach a depth of 100 mm in several minutes without depletion in the absence of reaction with surfaces. However, when the ozone gas reacted with the produce surface, gas concentration was significantly affected. Simulation data were validated experimentally by measuring ozone concentrations at the bottom of a cylinder made of lettuce leaf. The microbiological test confirmed the relationship between ozone transport, its self-decomposition, reaction with surrounding materials, and the degree of inactivation of E. coli K-12. Our study shows that decontamination of fresh produce, through direct contact with the sanitizer, is more feasible with gaseous than with aqueous sanitizers. Therefore, sanitization during a high-speed washing process is effective only for decontaminating the wash water.

    Full Text Available Lack of sanitation facilities is a common occurrence in informal settlements that are common in most developing countries. One challenge with sanitation provision in these settlements is the cost and financing of sanitation. This study aimed at estimating the cost of sanitation, and investigating the social and economic dynamics within Kisumu’s informal settlements that hinder provision and uptake of sanitation facilities. Primary data was collected from residents of the settlements, and using logistic and hedonic regression analysis, we identify characteristics of residents with sanitation facilities, and estimate the cost of sanitation as revealed in rental prices. Our study finds that sanitation constitutes approximately 54% of the rent paid in the settlements; and dynamics such as landlords and tenants preferences, and sharing of sanitation facilities influence provision and payment for sanitation. This study contributes to general development by estimating the cost of sanitation, and further identifies barriers and opportunities for improvement including the interplay between landlords and tenants. Provision of sanitation in informal settlements is intertwined in social and economic dynamics, and development approaches should target both landlords and tenants, while also engaging various stakeholders to work together to identify affordable and appropriate sanitation technologies.

    Drinking water and sanitation are two factors of inter-linked inextricably public health especially in the city of Nouakchott where the low availability of these services leads to a multitude of use and hygiene practices involving a complex socio-ecological system with an increased risk of waterborne diseases transmission (diarrhea, cholera, etc.). Thus, this contribution analyzes the impact of socio-ecological system on the development of diarrheal diseases by using socio-environmental and epidemiological data from various sources (national surveys and registries consultation). Overall, the results show that only 25.6% of households have access to drinking water sources while 69.8% of the populations dispose improved latrines. Hence, the weakness in environmental sanitation conditions explains the level of diarrheal morbidity averring 12.8% at the urban level, with an unequal spatial distribution showing less affected communes such as Tevragh Zeina (9.1%) and municipalities more affected like Sebkha (19.1%). The distribution according to the age categories shows that children under 5 years are the most affected with 51.7% followed by people aged over 14 with 34.2%. The correlation analysis between socio-economic, environmental and epidemiological variables reveals a number of significant associations: untreated water consumption and diarrhea (R = 0.429); collection of wastewater and occurrence of diarrhea ; existence of improved latrine and reduction of diarrheal risk (R = 0.402). Therefore, exposure to diarrheal diseases through the prism of water and sanitation is a real public health problem that requires a systemic and integrated approach to improving environmental health.

    Evidence on sanitation and hygiene program costs is used for many purposes. The few studies that report costs use top-down costing methods that are inaccurate and inappropriate. Community-led total sanitation (CLTS) is a participatory behavior-change approach that presents difficulties for cost analysis. We used implementation tracking and bottom-up, activity-based costing to assess the process, program costs, and local investments for four CLTS interventions in Ghana and Ethiopia. Data collection included implementation checklists, surveys, and financial records review. Financial costs and value-of-time spent on CLTS by different actors were assessed. Results are disaggregated by intervention, cost category, actor, geographic area, and project month. The average household size was 4.0 people in Ghana, and 5.8 people in Ethiopia. The program cost of CLTS was $30.34-$81.56 per household targeted in Ghana, and $14.15-$19.21 in Ethiopia. Most program costs were from training for three of four interventions. Local investments ranged from $7.93-$22.36 per household targeted in Ghana, and $2.35-$3.41 in Ethiopia. This is the first study to present comprehensive, disaggregated costs of a sanitation and hygiene behavior-change intervention. The findings can be used to inform policy and finance decisions, plan program scale-up, perform cost-effectiveness and benefit studies, and compare different interventions. The costing method is applicable to other public health behavior-change programs. Copyright © 2017 The Authors. Published by Elsevier B.V. All rights reserved.

    Application of nonfouling coatings on thermal processing equipment can improve operational efficiency. However, to enable effective commercial translation, a need exists for more comprehensive studies on the stability of nonfouling coatings after exposure to different sanitizers. In the current study, the influence of different commercial dairy equipment sanitizers on the nonfouling properties of stainless steel modified with electroless Ni-polytetrafluoroethylene (PTFE) coatings was determined. Surface properties, such as dynamic contact angle, surface energy, surface morphology, and elemental composition, were measured before and after the coupons were exposed to the sanitizers for 168 cleaning cycles. The fouling behavior of Ni-PTFE-modified stainless steel coupons after exposure was also evaluated by processing raw milk on a self-fabricated benchtop-scale plate heat exchanger. The results indicated that peroxide sanitizer had only minor effect on the Ni-PTFE-modified stainless steel surface, whereas chlorine- and iodine-based sanitizers influenced the surface properties drastically. The coupons after 168 cycles of exposure to peroxide sanitizer accumulated the least amount of fouling material (4.44±0.24mg/cm(2)) compared with the coupons exposed to the other 3 sanitizers. These observations indicated that the Ni-PTFE nonfouling coating retained antifouling properties after 168 cycles of exposure to peroxide-based sanitizer, supporting their potential application as nonfouling coatings for stainless steel dairy processing equipment.

    The use of alcohol-based hand sanitizers has recently become widespread. To the authors' knowledge, no previous study has examined whether application of ethanol-based hand sanitizers by the person operating a common breathalyzer machine will affect the accuracy of the readings. This was a prospective study investigating whether the use of hand sanitizer applied according to manufacturer's recommendations (Group I), applied improperly at standard doses (Group II), or applied improperly at high doses (Group III) had an effect on breathalyzer readings of individuals who had not ingested alcohol. The participants of the prospective study were divided into three groups to assess the effect of hand sanitizer on breathalyzer readings. Group I used one pump (1.5 mL) of hand sanitizer (Purell), allowing the hands to dry per manufacturer's recommendations; Group II used one pump (1.5 mL), without allowing the hands to dry; and Group III used two pumps (3 mL), without allowing the hands to dry. Breathalyzer measures for each group are presented as medians with interquartile ranges (IQR) and ranges. Differences between each sequential group (I vs. II and II vs. III) were assessed using a Mann-Whitney U-test (p hand sanitizer may cause false-positive readings with a standard hospital breathalyzer when the operator uses the hand sanitizer correctly.

    2017-03-01

    Sanitation is essential for promoting health, preventing environment pollution, conserving ecosystem, and recovering and recycling resources. Therefore, it can be said that sanitation is closely related to such current global issues as poverty, urban slum, conservation of ecosystem, and resources management. Namely, the question, “How can we handle the waste from 10 billion people in future?” is a global environmental problem to be solved. In developing world, population is growing rapidly especially in urban slums and they have still high under 5 mortality and poverty issues. It also reported that 2.4 billion people are still using unimproved sanitation facilities, including 946 million people who are still practicing open defecation in 2015 (UN, 2015). On the other hand, depopulation and aging are progressing especially in rural area of developed world. Based on the above mentioned background, new research project on sanitation value chain has started. This is a collaboration project with LIPI, RIHN (Research Institute of Humanity and Nature, Kyoto) and HU (Hokkaido University). The concept of the sanitation value chain and the brief summary of the project are discussed in the keynote presentation. The concept of sanitation value chain proposed in the project : The project is proposing new concept, Sanitation Value Chain, which has the following basic policies: 1) Put values of people/and community in the centre of discussion, and prepare sanitation system to drive this value chain; 2) Design the sanitation system by focusing on incentive for individual users and community; 3) Recognize a sanitation system as an integrated system with social and technical systems; 4) Design the sanitation system by making a good matching between social characteristics and prerequisites of the technologies. The goals of the research are 1) To propose the Sanitation Value Chain as a common solution for both developing and developed countries, 2) To show the validity of the

    2013-01-01

    Diacetyl is used to impart a buttery flavor to numerous food products such as sour cream, cottage cheese, vegetable oil-based spreads, baked goods, and beverages. Recent studies have linked exposure to high concentrations of diacetyl and the onset of bronchiolitis obliterans. Due to the reported risks that diacetyl may pose, many food companies have altered practices to reduce worker exposure to diacetyl, including the use of personal respirators, improved air handling systems, and adequate cleaning practices. Commonly used cleaning and sanitizing agents may be reactive with diacetyl; however, the efficacy of these chemicals has not been studied in detail and remains unclear. The objective of this work was to study the reaction chemistry of diacetyl with common industrial cleaning and sanitizing chemicals. The reactions were assessed at equimolar concentrations and analyzed by gas chromatography-mass spectrometry. Peroxyacetic acid was most reactive with diacetyl (95% reduction in diacetyl), followed by sodium hypochlorite (76% reduction), and hydrogen peroxide (26% reduction). Benzalkonium chloride (BAC) did not react with diacetyl. Acetic acid was detected as the main product of reactions of diacetyl with peroxyacetic acid, sodium hypochlorite, and hydrogen peroxide. 1,1-Dichloro-2-propanone and 1,1,1-trichloropropanone were also identified as volatile reaction products in the sodium hypochlorite reactions.

    Herd immunity arises when a communicable disease is less able to propagate because a substantial portion of the population is immune. Nonimmunizing interventions, such as insecticide-treated bednets and deworming drugs, have shown similar herd-protective effects. Less is known about the herd protection from drinking water, sanitation, and hand hygiene (WASH) interventions. We first constructed a transmission model to illustrate mechanisms through which different WASH interventions may provide herd protection. We then conducted an extensive review of the literature to assess the validity of the model results and identify current gaps in research. The model suggests that herd protection accounts for a substantial portion of the total protection provided by WASH interventions. However, both the literature and the model suggest that sanitation interventions in particular are the most likely to provide herd protection, since they reduce environmental contamination. Many studies fail to account for these indirect effects and thus underestimate the total impact an intervention may have. Although cluster-randomized trials of WASH interventions have reported the total or overall efficacy of WASH interventions, they have not quantified the role of herd protection. Just as it does in immunization policy, understanding the role of herd protection from WASH interventions can help inform coverage targets and strategies that indirectly protect those that are unable to be reached by WASH campaigns. Toward this end, studies are needed to confirm the differential role that herd protection plays across the WASH interventions suggested by our transmission model. © The American Society of Tropical Medicine and Hygiene.

  1. Access to Drinking Water and Sanitation in Rural Kazakhstan.

    2016-11-09

    The Sustainable Development Goals (SDGs) require nations to ensure adequate water supply for all. For Kazakhstan, this means that rural areas will need much stronger attention as they have been rather neglected in efforts to comply with the Millennium Development Goals (MDGs). This study aims to establish a baseline data concerning the current situation in villages that will need interventions according to the SDGs. The study was performed by means of questionnaires. The results should be seen as initial guidelines that can help to illuminate some of the uncounted challenges in future efforts to meet the SDG targets. As hardly any information exists about sanitation in rural Kazakhstan, the study essentially focuses on water services. The results show that 65% of rural dwellers want to connect and pay for the piped water supply. At the same time, about 80% have toilets outside their home. Consequently, the water program aiming at providing 80% of rural people with access to tap water from a centralized piped system will not be possible. However, by carefully managing the existing water supply and sanitation system in joint collaboration with the local users, significant progress can be made. The present results show the important first steps that need to be taken in this direction.

    Full Text Available Milk processing lines offer a wide variety of microenvironments where a diversity of microorganisms can proliferate. We sampled crevices and junctions where, due to deficient reach by typical sanitizing procedures, bacteria can survive and establish biofilms. The sampling sites were the holding cell, cold storage tank, pasteurizer and storage tank--transfer pump junction. The culturable bacteria that were isolated after the sanitation procedure were predominantly Pseudomonas spp., Serratia spp, Staphylococcus sciuri and Stenotrophomonas maltophilia. We assayed several phenotypic characteristics such as the ability to secrete enzymes and siderophores, as well as the capacity of the strains to form biofilms that might contribute to their survival in a mixed species environment. The Pseudomonas spp. isolates were found to either produce proteases or lecithinases at high levels. Interestingly, protease production showed an inverse correlation with siderophore production. Furthermore, all of the Serratia spp. isolates were strong biofilm formers and spoilage enzymes producers. The organisms identified were not mere contaminants, but also producers of proteins with the potential to lower the quality and shelf-life of milk. In addition, we found that a considerable number of the Serratia and Pseudomonas spp. isolated from the pasteurizer were capable of secreting compounds with antimicrobial properties.

    Practical, effective methods that could be implemented in a food service establishment (restaurant or delicatessen) for the surface sanitization of cantaloupes were microbiologically evaluated. Cantaloupes (Cucumis melo L. var. reticulates) were immersed in an inoculum containing Salmonella enterica serovar Poona or Pantoea agglomerans at ca. 10(4) to 10(5) CFU/ml. An efficient method for the recovery of bacteria from the cantaloupe surface was developed and validated. The method consisted of washing the entire melon with Butterfield's buffer containing 1% Tween 80 in a plastic bag placed inside a plastic pail affixed to an orbital shaker. Levels of S. enterica Poona recovered by washing the entire melon were significantly higher than those recovered by the more common laboratory method of blending the rind. P. agglomerans can be used as a non-pathogenic proxy for S. enterica Poona. A three-compartment surface sanitization method consisting of washing with an antimicrobial soap solution, scrubbing with a brush in tap water, and immersion in 150 ppm of sodium hypochlorite reduced the initial level of recoverable viable bacteria by 99.8%. When examined separately, scrubbing with a vegetable brush in tap water, washing with soap, and dipping in chlorine were found to reduce the bacterial load by 70, 80, and 90%, respectively.

    This paper critically assesses microfinance’s expansion into the provision of public goods. It focuses on the problem of public goods and collective action and refers to the specific example of water and sanitation. The microfinancing of water and sanitation is a private business model which requires households to recognise, internalise and capitalise the benefits from improved water and sanitation. This requirement is not assured. Water and sanitation, being closely linked to underlying c...

    2016-01-01

    After having indicated the relevant regulatory texts and guides, this guide defines ASN recommendations for the sanitation methodology to be applied when, for example, some premises of buildings are subject to a change of use, are to be demolished, or are to be cleaned after events which occurred during operation. Some definitions are first specified: sanitation objective, verification criterion, singular point, structure, area. After having rather briefly recalled the general doctrine adopted for waste management in basic nuclear installations, the guide states the ASN doctrine regarding structure sanitation by presenting various concepts: complete sanitation, extensive sanitation, and sanitation during operation. It presents principles of sanitation of constituent structures of an area which may produce nuclear wastes (three defence lines are distinguished: thoughtful definition of sanitation modalities, confirmation of the conventional character of structures after sanitation, radiological control of any waste). Administrative procedures are then addressed: before sanitation works, during sanitation works, and after sanitation works (depending on the compatibility of structure radiological condition). Quality assurance requirements are evoked. The guide then describes the modalities of definition of the three different defence lines, and indicates requirements regarding sanitation works (control of contamination dissemination, conditions of intervention, case of civil engineering metallic structures, control of remaining structure elements). A peculiar case is briefly addressed: sanitation of removable structure elements. Appendices indicate the main themes addressed by the sanitation methodology, and by the sanitation assessment. A model sheet is proposed to specify the downgrading of a premise which was previously classified as an area of possible production of nuclear wastes

    Like most cities in developing countries, Kigali is experiencing rapid urbanisation leading to an increase in the urban population and rapid growth in the size and number of informal settlements. More than 60% of the city's population resides in these settlements, where they experience inadequate and poor quality urban services including sanitation. This article discusses the issues and constraints related to the provision of sustainable sanitation in the informal settlements in Kigali. Two informal settlements (Gatsata and Kimisagara) were selected for the study, which used a mixed method approach for data collection. The research found that residents experienced multiple problems because of poor sanitation and that the main barrier to improved sanitation was cost. Findings from this study can be used by the city authorities in the planning of effective sanitation intervention strategies for communities in informal settlements.

    The development of a human right to water and sanitation under international law has created an imperative to implement human rights in water and sanitation policy. Through forty-three interviews with informants in international institutions, national governments, and non-governmental organizations, this research examines interpretations of this new human right in global governance, national policy, and local practice. Exploring obstacles to the implementation of rights-based water and sanitation policy, the authors analyze the limitations of translating international human rights into local water and sanitation practice, concluding that system operators, utilities, and management boards remain largely unaffected by the changing public policy landscape for human rights realization. To understand the relevance of human rights standards to water and sanitation practitioners, this article frames a research agenda to ensure that human rights aspirations lead to public policy reforms and public health outcomes.

    2017-10-01

    Unlike most quantitative studies that investigate decision-making on investing in sanitation, this study adopted a qualitative approach to investigate decision-making on shared sanitation in the informal settlements of Kisumu city, in Kenya. Using a grounded theory approach, landlords and tenants were interviewed to identify sanitation decisions, individuals involved in decision-making and factors influencing decision-making. The results indicate that the main sanitation decisions are on investment, emptying, repair and cleaning. Landlords make investment, emptying and repair decisions, while tenants make cleaning decisions. Absentee landlords are less involved in most decision-making compared to live-in landlords, who rarely consult tenants in decision-making. Tenants make decisions after consultations with a third party and often collectively with other tenants. Sanitation interventions in informal settlements should thus, target landlords and tenants, with investment efforts being directed at landlords and maintenance efforts at tenants.

  12. Shared sanitation versus individual household latrines: a systematic review of health outcomes.

    Directory of Open Access Journals (Sweden)

    Marieke Heijnen

    Full Text Available BACKGROUND: More than 761 million people rely on shared sanitation facilities. These have historically been excluded from international sanitation targets, regardless of the service level, due to concerns about acceptability, hygiene and access. In connection with a proposed change in such policy, we undertook this review to identify and summarize existing evidence that compares health outcomes associated with shared sanitation versus individual household latrines. METHODS AND FINDINGS: Shared sanitation included any type of facilities intended for the containment of human faeces and used by more than one household, but excluded public facilities. Health outcomes included diarrhoea, helminth infections, enteric fevers, other faecal-oral diseases, trachoma and adverse maternal or birth outcomes. Studies were included regardless of design, location, language or publication status. Studies were assessed for methodological quality using the STROBE guidelines. Twenty-two studies conducted in 21 countries met the inclusion criteria. Studies show a pattern of increased risk of adverse health outcomes associated with shared sanitation compared to individual household latrines. A meta-analysis of 12 studies reporting on diarrhoea found increased odds of disease associated with reliance on shared sanitation (odds ratio (OR 1.44, 95% CI: 1.18-1.76. CONCLUSION: Evidence to date does not support a change of existing policy of excluding shared sanitation from the definition of improved sanitation used in international monitoring and targets. However, such evidence is limited, does not adequately address likely confounding, and does not identify potentially important distinctions among types of shared facilities. As reliance on shared sanitation is increasing, further research is necessary to determine the circumstances, if any, under which shared sanitation can offer a safe, appropriate and acceptable alternative to individual household latrines.

    We undertook this systematic review to explore the relationship between sanitation and learning outcomes, specifically cognitive development and absence. We searched leading databases to identify experimental and observational studies that address the effect of sanitation on our outcomes of interest. We identified 17 studies that met the review's eligibility criteria, four reporting on measures of cognitive development, 12 on school absence (with two studies reporting on school and work absence), and one study that reported on both outcomes. We assessed the risk of bias of individual studies as well as the overall strength of evidence for each outcome. Because of fundamental differences among the studies in terms of sanitation exposure and outcome measurement, pooling results via meta-analysis was deemed inappropriate so a descriptive review is presented. Studies reported that access to household sanitation was associated with measures of improved cognitive ability in children. However, collectively these studies were rated by GRADE as poor methodological quality with significant potential for confounding and bias, including publication bias. Studies on the association between household, community or school sanitation and school absence yielded mixed results. Some sanitation studies reported lower absence while others reported higher absence. Only the two randomized controlled trials reported no overall effects on absence even when combining sanitation with water supply improvements and hygiene promotion. Study quality as assessed by GRADE was again generally poor. While studies to date provide some support for positive effects from sanitation on cognitive development, the effects on school absence are uncertain. Differences in effects may be due to differences in study settings, type of sanitation exposure and most notably in outcome definitions. Further research in multiple settings using rigorous study designs and measuring intermediate outcomes such as exposure

    The recent discovery of the bio-waste and excreta treatment of a former civilisation in the Amazon reveals the possibility of a highly efficient and simple sanitation system. With the end product that was black soil they converted 10% of former infertile soil of the region: Terra Preta do Indio (black soil of the Indians). These soils are still very fertile 500 years after this civilisation had disappeared. Deriving from these concepts, Terra Preta Sanitation (TPS) has been re-developed and adopted. TPS includes urine diversion, addition of a charcoal mixture and is based on lactic-acid-fermentation with subsequent vermicomposting. No water, ventilation or external energy is required. Natural formation processes are employed to transform excreta into lasting fertile soil that can be utilised in urban agriculture. The authors studied the lacto-fermentation of faecal matter with a minimum of 4 weeks followed by vermicomposting. The results showed that lactic-acid fermentation with addition of a charcoal mixture is a suitable option for dry toilets as the container can be closed after usage. Hardly any odour occured even after periods of several weeks. Lactic-acid fermentation alone without addition of bulking agents such as paper and sliced-cut wood to raise the C/N ratio is creating a substrate that is not accepted by worms.

    2013-03-01

    Economic evidence on the cost and benefits of sanitation and drinking-water supply supports higher allocation of resources and selection of efficient and affordable interventions. The study aim is to estimate global and regional costs and benefits of sanitation and drinking-water supply interventions to meet the Millennium Development Goal (MDG) target in 2015, as well as to attain universal coverage. Input data on costs and benefits from reviewed literature were combined in an economic model to estimate the costs and benefits, and benefit-cost ratios (BCRs). Benefits included health and access time savings. Global BCRs (Dollar return per Dollar invested) were 5.5 for sanitation, 2.0 for water supply and 4.3 for combined sanitation and water supply. Globally, the costs of universal access amount to US$ 35 billion per year for sanitation and US$ 17.5 billion for drinking-water, over the 5-year period 2010-2015 (billion defined as 10(9) here and throughout). The regions accounting for the major share of costs and benefits are South Asia, East Asia and sub-Saharan Africa. Improved sanitation and drinking-water supply deliver significant economic returns to society, especially sanitation. Economic evidence should further feed into advocacy efforts to raise funding from governments, households and the private sector.

  1. Access to Sanitation Facilities among Nigerian Households: Determinants and Sustainability Implications

    2017-04-01

    Full Text Available Access to improved sanitation facilities is key to the socioeconomic wellbeing and sustainable development of any society. This study examines access to sanitation facilities in Nigeria and explores the socioeconomic and locational factors that influence the type of facility used by households. The study utilizes cross-sectional data from the 2013 Nigeria Demographic and Health Survey, and employs descriptive and inferential statistics for data analyses. The results indicated that 44.2% of households used various kinds of pit latrines, followed by toilets that flush to septic tanks (10.3%. While only 5.3% of the respondents used toilets that connect to sewer systems, about a third (31.5% lacked sanitation facility and the remaining 8.7% used other types of sanitation facilities. Results from chi-square analysis and ANOVA revealed significant statistical differences between the type of sanitation facility households used and their place of residence, geopolitical zone, ethnicity, educational attainment and wealth. Multivariate regression results indicated that the type of household sanitation facility is significantly associated with the mentioned factors as well as household size, gender of the head of the household, type of water sources, number of rooms and access to electricity. Age of the head of the household and type of cooking fuel used were not significant. The study concludes by underscoring the implications of using unimproved sanitation facilities on human health and environmental sustainability.

    While the topic of women and water, sanitation and hygiene is a widely accepted concern among academics and activists, it continues to be an issue in developing countries with serious consequences. Based on a qualitative research conducted in rural Uttar Pradesh, India, the paper affirms that sanitation issues for women and girls are compounded by inequitable gender norms that put them at greater risk of experiencing violence and multiple health vulnerabilities. Women, despite having a high demand for safe toilet facilities, continue to practise unsafe sanitation. The findings highlight the role of three structural constraints as the key factors influencing toilet construction and use: poverty, inadequate sanitation policy and its implementation and gender-based power dynamics at the household level. The paper concludes by emphasising the relevance of engendering sanitation programmes and policies by involving women and girls in the planning process to ensure that dignified and gender-sensitive sanitation solutions are developed. The paper also stresses the need to have measures for strengthening and effectively implementing a sanitation policy for the poor and for programmes to work with both men and women to address gender power relations which influence toilet adoption and use.

    Nosocomial infections are a major problem in health care facilities, resulting in extended durations of care and substantial morbidity. Since alcohol gel hand sanitizers combine high immediate antimicrobial efficacy with ease of use, this study was carried out to determine the effect of the use of alcohol gel hand sanitizer by caregivers on infection types and rates in an extended care facility. Infection rate and type data were collected in a 275-bed extended care facility for 34 months (July 1997 to May 2000), during which an alcohol gel hand sanitizer was used by the caregivers in 2 units of the facility. The primary infection types found were urinary tract with Foley catheter, respiratory tract, and wound infections. Comparison of the infection types and rates for the units where hand sanitizer was used with those for the control units where the hand sanitizer was not used showed a 30.4% decrease in infection rates for the 34-month period in the units where hand sanitizer was used. This study indicates that use of an alcohol gel hand sanitizer can decrease infection rates and provide an additional tool for an effective infection control program.

  4. Conflict of technologies for water and sanitation in developing countries.

    2000-01-01

    Borehole water supplies, in basement rock aquifers in the West Africa Sub-region, face potential pollution hazards as a result of their close location within the same geological environments as indiscriminately sited latrines, rubbish dumps, farms and animal watering points in the communities. The heterogeneous nature of the overburden and fractures in the bedrock constitute relatively fast flow paths for surface water contaminated mainly by bacteria and nitrates which enhance the pollution of the groundwater and boreholes. To improve the drinking water quality, some measures have been taken to minimize the hazards. Further studies are required to understand better the nature and scale of the problem and to avoid the apparent conflict of technologies. It is necessary to incorporate improvements in sanitation into rural water supply projects, if the otherwise good drinking water source should not be lost to society's wastes.

    Recently, we investigated the impact of shared equipment on cross-contamination of cookies at a pilot plant scale. Based on those findings, this study investigated the extent and subsequent sanitation of hazelnut cross-contamination (HNCC) of cookies at the industrial scale. Similarly, a product change from cookies with hazelnut ingredient to cookies without hazelnut was performed on standard equipment. HNCC in the hazelnut-free follow-up product was quantified by enzyme-linked immunosorbent assay for each production device and the applied cleaning procedure. All experiments were repeated in duplicate. The highest HNCC was found in concordance with previous studies after mere mechanical scraping: more than 1,000 mg of hazelnut protein per kg was quantified in the follow-up product after processing by a cookie machine. Additional cleaning with hot water decreased the HNCC irrespective of the processing device to levels at or below 1 mg of hazelnut protein per kg. Furthermore, raw materials for cookie production were monitored over a period of 24 months for unwanted preloads of hazelnut and peanut: hazelnut was quantified in 16% of the investigated raw materials as being between 0.26 and 90 mg/kg. Further critical control points at the industrial scale, where cross-contamination might occur, were identified but did not display noteworthy sources of cross-contamination. In conclusion, the quantitative monitoring of the cleaning efficiency at the industrial scale confirmed the procedure of manual scraping plus wet cleaning as a qualified sanitation procedure to effectively reduce the hazelnut protein cross-contamination down to a level at which severe hazelnut-related allergic reactions are unlikely to occur.

    The willingness to pay (WTP) for the construction of bathrooms with a flush toilet was assessed in households in a rural community in northern Vietnam. We also examined the effects of socio-economic factors on the WTP. The contingent valuation method, an economic survey technique, was used. We used the iterative bidding game technique to elicit household WTP that involved a sequence of dichotomous choice questions followed by a final open-ended question. A total of 370 households that did not have toilets were selected for this study. Respondents to the questionnaire were the primary income earners and decision-makers of their respective household. Of those responding to the questionnaire, 62.1 % reported being willing to pay for the construction of bathrooms with a flush toilet. The mean and median of maximum WTP amounts were Viet Nam Dong (VND) 15.6 million and VND 13.0 million, respectively (minimum VND 2.0 million; maximum VND 45.0 million). Significant correlates of the WTP rate were: (1) gender of the head of household, (2) age of the head of household, (3) economic status of household, (4) type of current toilet, (5) satisfaction with existing toilet, and (6) knowledge of health effects of poor sanitation. The significant determinants of WTP amount were (1) geographic location and (2) economic status of household. About two-third of the households in the study area were willing to pay for an improvement in their current sanitation arrangements. Both WTP rate and WP amount were strongly influenced by the economic status of the households and health knowledge of the study respondents.

    Purpose The purpose of this paper is to determine water availability, sanitation and hygiene (WSH) services, and healthcare waste management in Jordan healthcare facilities. Design/methodology/approach In total, 19 hospitals (15 public and four private) were selected. The WSH services were assessed in hospitals using the WSH in health facilities assessment tool developed for this purpose. Findings All hospitals (100 percent) had a safe water source and most (84.2 percent) had functional water sources to provide enough water for users' needs. All hospitals had appropriate and sufficient gender separated toilets in the wards and 84.2 percent had the same in outpatient settings. Overall, 84.2 percent had sufficient and functioning handwashing basins with soap and water, and 79.0 percent had sufficient showers. Healthcare waste management was appropriately practiced in all hospitals. Practical implications Jordan hospital managers achieved major achievements providing access to drinking water and improved sanitation. However, there are still areas that need improvements, such as providing toilets for patients with special needs, establishing handwashing basins with water and soap near toilets, toilet maintenance and providing sufficient trolleys for collecting hazardous waste. Efforts are needed to integrate WSH service policies with existing national policies on environmental health in health facilities, establish national standards and targets for the various healthcare facilities to increase access and improve services. Originality/value There are limited WSH data on healthcare facilities and targets for basic coverage in healthcare facilities are also lacking. A new assessment tool was developed to generate core WSH indicators and to assess WSH services in Jordan's healthcare facilities. This tool can be used by a non-WSH specialist to quickly assess healthcare facility-related WSH services and sanitary hazards in other countries. This tool identified some areas

    Hand sanitizers are effective and inexpensive products that can reduce microorganisms on the skin, but ingestion or improper use can be associated with health risks. Many hand sanitizers contain up to 60%-95% ethanol or isopropyl alcohol by volume, and are often combined with scents that might be appealing to young children. Recent reports have identified serious consequences, including apnea, acidosis, and coma in young children who swallowed alcohol-based (alcohol) hand sanitizer (1-3). Poison control centers collect data on intentional and unintentional exposures to hand sanitizer solutions resulting from various routes of exposure, including ingestion, inhalation, and dermal and ocular exposures. To characterize exposures of children aged ≤12 years to alcohol hand sanitizers, CDC analyzed data reported to the National Poison Data System (NPDS).* The major route of exposure to both alcohol and nonalcohol-based (nonalcohol) hand sanitizers was ingestion. The majority of intentional exposures to alcohol hand sanitizers occurred in children aged 6-12 years. Alcohol hand sanitizer exposures were associated with worse outcomes than were nonalcohol hand sanitizer exposures. Caregivers and health care providers should be aware of the potential dangers associated with hand sanitizer ingestion. Children using alcohol hand sanitizers should be supervised and these products should be kept out of reach from children when not in use.

    Full Text Available The objective of this study was to investigate Escherichia coli adhesion on new and used polyethylene cutting board surface and evaluate it’s removal using different sanitizer (peracetic acid,chlorhexidine, sodium hypochlorite and organic acids. Results indicated that the number of adherent cells increased with time in both surfaces evaluated. Evaluating the sanitizer action, 0.5%peracetic acid was more effective in removal E. coli than chlorhexidine and organic acids at same concentration in both surfaces. Peracetic acid and sodium hypochlorite also showed effectiveness at concentrations of 0.2% and 0.5% on new surfaces, respectively. 0.8% of chlorhexidine and 2.0% of organic acids showed similar effectiveness in the removal E. coli on new and used surfaces, respectively.These results suggest that peracetic acid is considerable promise sanitizer for application in surfaces of the food processing industry.

    Full Text Available The effects of crop sanitation and reduced sprays of "Ridomil plus®" (12 % metalaxyl + 60 % cuprous oxide on the control of potato (Solanum tuberosum late blight caused by Phytophthora infestans were evaluated in two field experiments in 1993 in Dschang, Cameroon. In the first experiment, sanitation (five weekly removals of blighted leaves and two fungicidal treatments were initiated from first symptoms. In the second experiment, both fungicidal sprays were made at varying rates. Marketable yields increased by 50 % in sanitation-treated plots, by 94 % in plots sprayed with Ridomil plus (2.24 kg a. i./ha, or by 55 % in those exposed to both control methods. The fungicide equivalence of the sanitation treatment was two sprays of Ridomil plus at 0.76 kg a. i./ha. These results suggest that proper removal of diseased leaves or reduced fungicidal protection may be an effective late blight control method in potato farming.

    Full Text Available Abstract Background Shared facilities are not recognised as improved sanitation due to challenges of maintenance as they easily can be avenues for the spread of diseases. Thus there is need to evaluate the quality of shared facilities, especially in informal settlements, where they are commonly used. A shared facility can be equated to a common good whose management depends on the users. If users do not work collectively towards keeping the facility clean, it is likely that the quality may depreciate due to lack of maintenance. This study examined the quality of shared sanitation facilities and used the common pool resource (CPR management principles to examine the determinants of shared sanitation quality in the informal settlements of Kisumu, Kenya. Methods Using a multiple case study design, the study employed both quantitative and qualitative methods. In both phases, users of shared sanitation facilities were interviewed, while shared sanitation facilities were inspected. Shared sanitation quality was a score which was the dependent variable in a regression analysis. Interviews during the qualitative stage were aimed at understanding management practices of shared sanitation users. Qualitative data was analysed thematically by following the CPR principles. Results Shared facilities, most of which were dirty, were shared by an average of eight households, and their quality decreased with an increase in the number of households sharing. The effect of numbers on quality is explained by behaviour reflected in the CPR principles, as it was easier to define boundaries of shared facilities when there were fewer users who cooperated towards improving their shared sanitation facility. Other factors, such as defined management systems, cooperation, collective decision making, and social norms, also played a role in influencing the behaviour of users towards keeping shared facilities clean and functional. Conclusion Apart from hardware factors, quality

    People with diabetes mellitus are instructed to clean their skin prior to self-monitoring of blood glucose to remove any dirt or food residue that might affect the reading. Alcohol-based hand sanitizers have become popular when soap and water are not available. The aim of this study was to determine whether a hand sanitizer is compatible with glucose meter testing and effective for the removal of exogenous glucose. We enrolled 34 nonfasting subjects [14 male/20 female, mean ages 45 (standard deviation, 9.4)] years, 2 with diagnosed diabetes/32 without known diabetes]. Laboratory personnel prepared four separate fingers on one hand of each subject by (1) cleaning the second finger with soap and water and towel drying (i.e., control finger), (2) cleaning the third finger with an alcohol-based hand sanitizer, (3) coating the fourth finger with cola and allowing it to air dry, and (4) coating the fifth finger with cola and then cleaning it with the instant hand sanitizer after the cola had dried. Finger sticks were performed on each prepared finger and blood glucose was measured. Several in vitro studies were also performed to investigate the effectiveness of the hand sanitizer for removal of exogenous glucose.z Mean blood glucose values from fingers cleaned with instant hand sanitizer did not differ significantly from the control finger (p = .07 and .08, respectively) and resulted in 100% accurate results. Blood glucose data from the fourth (cola-coated) finger were substantially higher on average compared with the other finger conditions, but glucose data from the fifth finger (cola-coated then cleaned with hand sanitizer) was similar to the control finger. The data from in vitro experiments showed that the hand sanitizer did not adversely affect glucose meter results, but when an exogenous glucose interference was present, the effectiveness of the hand sanitizer on glucose bias (range: 6% to 212%) depended on the surface area and degree of dilution. In our study

    Access to sanitation facilities is imperative in reducing the risk of multiple adverse health outcomes. A distinct disparity in sanitation exists among different wealth levels in many low-income countries, which may hinder the progress across each of the Millennium Development Goals. The surveyed households in 397 clusters from 2008-2009 Kenya Demographic and Health Surveys were divided into five wealth quintiles based on their national asset scores. A series of spatial analysis methods including excess risk, local spatial autocorrelation, and spatial interpolation were applied to observe disparities in coverage of improved sanitation among different wealth categories. The total number of the population with improved sanitation was estimated by interpolating, time-adjusting, and multiplying the surveyed coverage rates by high-resolution population grids. A comparison was then made with the annual estimates from United Nations Population Division and World Health Organization /United Nations Children's Fund Joint Monitoring Program for Water Supply and Sanitation. The Empirical Bayesian Kriging interpolation produced minimal root mean squared error for all clusters and five quintiles while predicting the raw and spatial coverage rates of improved sanitation. The coverage in southern regions was generally higher than in the north and east, and the coverage in the south decreased from Nairobi in all directions, while Nyanza and North Eastern Province had relatively poor coverage. The general clustering trend of high and low sanitation improvement among surveyed clusters was confirmed after spatial smoothing. There exists an apparent disparity in sanitation among different wealth categories across Kenya and spatially smoothed coverage rates resulted in a closer estimation of the available statistics than raw coverage rates. Future intervention activities need to be tailored for both different wealth categories and nationally where there are areas of greater needs when

    Shell eggs can be contaminated with many types of microorganisms, including bacterial pathogens, and thus present a risk for the transmission of foodborne disease to consumers. Currently, most United States egg processors utilize egg washing and sanitization systems to decontaminate surfaces of shell eggs prior to packaging. However, previous research has indicated that current shell egg sanitization technologies employed in the commercial egg industry may not completely eliminate bacteria from the surface of eggshells, and thus alternative egg sanitization technologies with the potential for increased microbial reductions on eggshells should be investigated. The objectives of this study were to compare the antimicrobial efficacy and consumer sensory attributes of industry-available eggshell sanitization methods (chlorine and quaternary ammonium compounds (QAC) applied via spray) to various alternative egg sanitization technologies. Eggs (White Leghorn hens; n=195) were obtained for evaluation of sanitizer-induced reduction in mesophilic aerobic bacteria (n=90) or inoculated Salmonella Enteritidis (SE) reduction (n=105). Sanitizing treatments evaluated in this experiment were: chlorine spray (100 ppm available chlorine), QAC spray (200 ppm), peracetic acid spray (PAA; 135 ppm) alone or in combination with ultraviolet light (UV; 254 nm), and hydrogen peroxide (H2O2; 3.5% solution) spray in combination with UV (H2O2+UV). For enumeration of aerobic bacteria, eggs were sampled at 0, 7, and 14 days of storage at 4°C; surviving SE cells from inoculated eggs were enumerated by differential plating. Sensory trials were conducted to determine consumer liking of scrambled eggs made from eggs sanitized with chlorine, QAC, H2O2+UV, or no treatment (control). The H2O2 and UV treatment resulted in the greatest reductions in eggshell aerobic plate counts compared to other treatments throughout egg storage (Peggs represents a novel technology that could have important

This included a cross sectional survey among 475 randomly selected households. These were classified as either having a functional latrine, a non-functional latrine or no latrine at all. We also conducted 17 in-depth interviews and 9 focus group discussions among household members of these three categories of households.Decisions on the construction of household level sanitation facilities were made exclusively by the male head in 80% of households; in 11% the decision was made by men who consulted or otherwise involved women. In only 9% of households the decision was made by women. Households where women were more involved in general decision making processes were no more likely to build a latrine, compared to households where they were excluded from decisions. Qualitative research revealed that women's non-involvement in sanitation decision making is attributed to their low socio-economic status and inability to influence the household's financial decisions. Female heads lacked confidence to take decisions independently, and were dependent on their spouse or other male family members for most decisions. The study revealed the existence of power hierarchies and dynamics within households, which constrained female's participation in decision-making processes regarding sanitation.Though governments and implementers emphasize women's involvement in sanitation programmes, socio-cultural factors and community and household level dynamics often prevent women from participating in sanitation-related decisions.

    Sanitation delivery in the urban areas of sub-Saharan African countries has been a chronic issue, particularly difficult to tackle. Under the Millennium Development Goals, the sanitation target in urban sub-Saharan Africa was missed by a wide margin and witnessed almost no improvement. After 2 years of review, the WHO/UNICEF Joint Monitoring Programme published a new measure of access to sanitation as a baseline for the Sustainable Development Goals. There are a number of improvements in the new measure. However, despite the improvements, the new measure continues to be characterized by an important flaw: it continues to disregard how shared toilet facilities contribute towards the SDG sanitation target. As a result, the new measure does not indicate whether progress is being made in low-income urban areas where a large number of households rely on shared sanitation; nor does it provide a goal that can be achieved in cities of the poorest countries over the measurement period. But, its most egregious failing is that it directs resources towards investments which will often fail cost/benefit tests. In sum, it is not a surprise that a Working Group recommended that the measure should be changed to include some shared facilities. Following the Working Group's recommendation would have avoided the adverse consequences of continued reliance on a key component of the methodology used for monitoring sanitation improvements under the Millennium Development Goals. The paper discusses the limitations of this methodology in the context of urban sub-Saharan Africa, where current sanitation conditions are seriously lacking, and the significant future urban population growth will add more pressure for the delivery of vital sanitation services.

    While uncommon, ingestion of ethanol-based hand sanitizers by children may be associated with significant intoxication. We report the case of a 7-year-old with acute alcohol intoxication following hand sanitizer ingestion. Alcohol elimination in this patient followed zero-order kinetics with a clearance rate of 22.5 mg/kg/h, consistent with the limited pharmacokinetic information available for children who experience alcohol intoxication from more traditional sources.

    These studies evaluated the effectiveness of ethanol hand sanitizers with or without organic acids to remove detectable rhinovirus from the hands and prevent experimental rhinovirus infection. Ethanol hand sanitizers were significantly more effective than hand washing with soap and water. The addition of organic acids to the ethanol provided residual virucidal activity that persisted for at least 4 h. Whether these treatments will reduce rhinovirus infection in the natural setting remains to be determined. PMID:20047916

    Improved sanitation access is extremely low in rural Cambodia. Non-governmental organizations have helped build local supply side latrine markets to promote household latrine purchase and use, but households cite inability to pay as a key barrier to purchase. To examine the extent to which microfinance can be used to facilitate household investment in sanitation, we applied a two-pronged assessment: (1) to address the gap between interest in and use of microfinance, we conducted a pilot study to assess microfinance demand and feasibility of integration with a sanitation marketing program and (2) using a household survey (n = 935) at latrine sales events in two rural provinces, we assessed attitudes about microfinance and financing for sanitation. We found substantial stated intent to use a microfinance institution (MFI) loan to purchase a latrine (27%). Five percent of current owners used an MFI loan for latrine purchase. Credit officers attended 159 events, with 4761 individuals attending. Actual loan applications were low, with 4% of sales events attendees applying for a loan immediately following the event (mean = 1.7 loans per event). Ongoing coordination was challenging, requiring management commitment from the sanitation marketing program and commitment to social responsibility from the MFI. Given the importance of improving sanitation coverage and concomitant health impacts, linking functional sanitation markets to already operational finance markets has the potential to give individuals and households more financial flexibility. Further product research and better integration of private vendors and financing modalities are necessary to create a scalable microfinance option for sanitation markets. © The Author 2016.

    While sanitation interventions have focused primarily on child health, women's unique health risks from inadequate sanitation are gaining recognition as a priority issue. This study examines the range of sanitation-related psychosocial stressors during routine sanitation practices in Odisha, India. Between August 2013 and March 2014, we conducted in-depth interviews with 56 women in four life stages: adolescent, newly married, pregnant and established adult women in three settings: urban slums, rural villages and indigenous villages. Using a grounded theory approach, the study team transcribed, translated, coded and discussed interviews using detailed analytic memos to identify and characterize stressors at each life stage and study site. We found that sanitation practices encompassed more than defecation and urination and included carrying water, washing, bathing, menstrual management, and changing clothes. During the course of these activities, women encountered three broad types of stressors-environmental, social, and sexual-the intensity of which were modified by the woman's life stage, living environment, and access to sanitation facilities. Environmental barriers, social factors and fears of sexual violence all contributed to sanitation-related psychosocial stress. Though women responded with small changes to sanitation practices, they were unable to significantly modify their circumstances, notably by achieving adequate privacy for sanitation-related behaviors. A better understanding of the range of causes of stress and adaptive behaviors is needed to inform context-specific, gender-sensitive sanitation interventions. Copyright © 2015 The Authors.

    Handwashing is difficult in settings with limited resources and water access. In primary schools within urban Kibera, Kenya, we investigated the impact of providing waterless hand sanitizer on student hand hygiene behavior. Two schools received a waterless hand sanitizer intervention, two schools received a handwashing with soap intervention, and two schools received no intervention. Hand cleaning behavior after toilet use was monitored for 2 months using structured observation. Hand cleaning after toileting was 82% at sanitizer schools (N = 2,507 toileting events), 38% at soap schools (N = 3,429), and 37% at control schools (N = 2,797). Students at sanitizer schools were 23% less likely to have observed rhinorrhea than control students (P = 0.02); reductions in student-reported gastrointestinal and respiratory illness symptoms were not statistically significant. Providing waterless hand sanitizer markedly increased student hand cleaning after toilet use, whereas the soap intervention did not. Waterless hand sanitizer may be a promising option to improve student hand cleansing behavior, particularly in schools with limited water access. PMID:23836575

    2017-12-01

    Following an increase in Roma migration under the European "freedom of movement" laws, Swedish municipalities initiated more than 80 evictions of informal Roma settlements on the grounds of poor sanitation between 2013 and 2016. These evictions echo policies from earlier in the 20th century, when Roma living in Sweden were often marginalized through the denial of access to water and sanitation facilities. The recent Swedish evictions also follow similar government actions across Europe, where Roma settlements are controlled through the denial of access to water and sanitation. However, access to water and sanitation-central aspects of human health-are universal human rights that must be available to all people present in a jurisdiction, regardless of their legal status. The evictions described here violated Sweden's obligations under both European and international human rights law. More positive government responses are required, such as providing shelters or camping sites, setting up temporary facilities, and directly engaging with communities to address water and sanitation issues. The authors conclude by providing guidance on how states and municipalities can meet their human rights obligations with respect to water and sanitation for vulnerable Roma individuals and informal settlements in their communities.

    Monitoring progress towards the targets for access to safe drinking-water and sanitation under the Millennium Development Goals (MDG) requires reliable estimates and indicators. We analyzed trends and reviewed current indicators used for those targets. We developed continuous time series for 1990 to 2015 for access to improved drinking-water sources and improved sanitation facilities by country using multilevel modeling (MLM). We show that MLM is a reliable and transparent tool with many advantages over alternative approaches to estimate access to facilities. Using current indicators, the MDG target for water would be met, but the target for sanitation missed considerably. The number of people without access to such services is still increasing in certain regions. Striking differences persist between urban and rural areas. Consideration of water quality and different classification of shared sanitation facilities would, however, alter estimates considerably. To achieve improved monitoring we propose: (1) considering the use of MLM as an alternative for estimating access to safe drinking-water and sanitation; (2) completing regular assessments of water quality and supporting the development of national regulatory frameworks as part of capacity development; (3) evaluating health impacts of shared sanitation; (4) using a more equitable presentation of countries' performances in providing improved services.

    There is growing evidence that household water treatment interventions improve microbiological water quality and reduce diarrheal disease risk. Few studies have examined, however, the impact of water treatment interventions on household-level hygiene and sanitation. This study examined the association of four water and sanitation conditions (access to latrines, improved sanitation, improved water and the plastic biosand filter) on the levels of total coliforms and E. coli on existing and introduced toys during an on-going randomized controlled trial of the plastic biosand filter (plastic BSF). The following conditions were associated with decreased bacterial contamination on children's toys: access to a latrine, access to improved sanitation and access to the plastic BSF. Overall, compared to existing toys, introduced toys had significantly lower levels of both E. coli and total coliforms. Results suggest that levels of fecal indicator bacteria contamination on children's toys may be associated with access to improved water and sanitation conditions in the home. In addition, the fecal indicator bacteria levels on toys probably vary with duration in the household. Additional information on how these toys become contaminated is needed to determine the usefulness of toys as indicators or sentinels of water, sanitation and hygiene conditions, behaviors and risks.

    A protocol for the cleaning and sanitization method for radiopharmaceutical production facilities has been designed and developed for the inner surface of the hot cells for the production of Sodium Pertechnetate Tc-99m and Sm-153 EDTMP, considering an extreme situation for each hot cell. Cleaning is performed with double-distilled water and sanitation with two disinfectant solutions, 70 % isopropyl alcohol and 3 % hydrogen peroxide in alternate weeks. Microbiological analysis of sanitized surfaces were made after 20 minutes and 48 hours for the hot cell of Tc-99m and 72 hours for the hot cell of EDTMP Sm-153 in 3 consecutive tests by the method of direct contact with plates containing culture medium, made for each sampling point (6 in the first and five in the second). The results showed that the microbial load on surfaces sanitized was below acceptable limits and that the lifetime of cleaning and sanitization is 48 hours for the hot cell of Tc-99m and 72 hours for the one of EDTMP-Sm-153. As a conclusion, the method of cleaning and sanitization is effective to reduce or eliminate microbial contamination therefore, the process is validated. (authors).

  6. Amplifying Progress toward Multiple Development Goals through Resource Recovery from Sanitation.

    2017-09-19

    The United Nations' Sustainable Development Goals (SDGs) recognize that current sanitation gaps must be closed to better serve those without access to safely managed systems (Target 6.2: universal sanitation coverage) and those connected to sewers without wastewater treatment (Target 6.3: halving the proportion of untreated wastewater). Beyond mitigating environmental and health concerns, implementing resource recovery sanitation systems could simultaneously improve the availability of agricultural nutrients (SDG 2) and household energy (SDG 7). This study estimates the potential for global, regional, and country-level resource recovery to impact nutrient and household electricity use through 2030. We distinguish impacts from newly installed sanitation systems (to achieve universal coverage), newly treated wastewater systems (to halve the proportion of untreated wastewater), and existing system replacement, while also considering urban and rural disparities and spatial colocation of nutrients with agricultural needs. This work points toward country-specific strategies for deriving the greatest benefit from sanitation investments while also identifying overarching trends to guide international research efforts. Globally, potential nutrient gains are an order of magnitude larger than electricity (a small fraction of total energy), and considerable impacts are possible in the least-developed countries, six of which could double or offset all projected nutrient and electricity use through newly installed sanitation systems.

    Diarrhoea is an important health issue in low- and middle-income countries, including Indonesia. We applied a multilevel regression analysis on the Indonesian Demographic and Health Survey to examine the effects of drinking water and sanitation facilities at the household and community level on diarrhoea prevalence among children under five (n = 33,339). The role of the circumstances was explored by studying interactions between the water and sanitation variables and other risk factors. Diarrhoea prevalence was reported by 4820 (14.4%) children, who on average were younger, poorer and were living in a poorer environment. At the household level, piped water was significantly associated with diarrhoea prevalence (OR = 0.797, 95% CI: 0.692-0.918), improved sanitation had no direct effect (OR = 0.992, 95% CI: 0.899-1.096) and water treatment was not related to diarrhoea incidence (OR = 1.106, 95% CI: 0.994-1.232). At the community level, improved water coverage had no direct effect (OR = 1.002, 95% CI: 0.950-1.057) but improved sanitation coverage was associated with lower diarrhoea prevalence (OR = 0.917, 95% CI: 0.843-0.998). Our interaction analysis showed that the protective effects of better sanitation at the community level were increased by better drinking water at the community level. This illustrates the importance of improving both drinking water and sanitation simultaneously.

    To pilot two intensive hand hygiene promotion interventions, one using soap and one using a waterless hand sanitizer, in low-income housing compounds in Dhaka, Bangladesh and assess subsequent changes in handwashing behaviour and hand microbiology. Fieldworkers randomized 30 housing compounds: 10 received handwashing promotion with free soap, 10 received handwashing promotion with free waterless hand sanitizer and 10 were non-intervention controls. Fieldworkers assessed handwashing behaviour by structured observation and collected hand rinse specimens. At baseline, compound residents washed their hands with soap 26% of the time after defecation and 30% after cleaning a child's anus but hands with soap after faecal contact (85-91%), before preparing food (26%) and before eating (26%). Compounds that received waterless hand sanitizer cleansed their hands more commonly than control compounds that used soap (10.4%vs. 2.3%), but less commonly than soap intervention compounds used soap (25%). Post-intervention hand rinse samples from soap and sanitizer compounds had lower concentrations of faecal indicator bacteria compared with baseline and control compounds. Waterless hand sanitizer was readily adopted by this low-income community and reduced hand contamination but did not improve the frequency of handwashing compared with soap. Future deployments of waterless hand sanitizers may improve hand hygiene more effectively by targeting settings where soap and water is unavailable. © 2010 Blackwell Publishing Ltd.

    There had been reports of adolescents using hand sanitizers to obtain alcohol and ending up in emergency departments with alcohol poisoning. This study aimed to describe the pattern of adolescent ingestions of hand sanitizers reported to a statewide poison center system. Our study subjects included patients aged 13-19 years who reported hand sanitizer ingestions as reported to Texas poison centers during 2000-2013. The distribution of the ingestions was determined for various demographic and clinical factors. Of 385 total cases, 61% of the patients were male, and the mean age was 15.3 years. The ingestion reason was unintentional (61%), intentional abuse/misuse (18%), and malicious (10%). Ingestion site was most frequently reported to be the patient's own residence (53%), followed by school (35%). About 77% of the patients were managed on site. The medical outcome was serious (moderate effect or unable to follow-potentially toxic) in 5% of the cases. The most frequently reported adverse clinical effects were vomiting (5%), abdominal pain (4%), nausea (4%), throat irritation (4%), and drowsiness (2%). Adolescents who ingested hand sanitizers were more likely to be male and younger. One-third of the ingestions occurred at school, suggesting that school personnel might be made aware of the potential problem of hand sanitizer ingestions by adolescents. Nevertheless, despite the potential for serious outcomes from adolescent hand sanitizer ingestion, most of the ingestions reported to poison centers are not likely to be serious and can be successfully managed outside of a healthcare facility.

    Using hand sanitizers can reduce bacterial contamination and is an efficient and inexpensive method of preventing infections. The purpose of this study was to explore the behavioral intention (low and absolute), attitudes, subjective norms, and perceived behavioral control of hand sanitizer use among US Army soldiers. A questionnaire was developed following an expert panel (N = 5) review and 2 pilot studies (N = 35) to ensure questionnaire validity and clarity. Surveys were distributed among nontrainee soldiers during lunch periods. A total of 201 surveys were collected. Results indicated that attitudes, subjective norms, and perceived behavioral controls explained 64% of the variance in behavioral intention. Attitude remained the strongest predictor of behavior (β = 0.70, P hand sanitizers hold significantly different behavioral and normative beliefs than low intenders. Other soldiers create negative social pressure about using hand sanitizers, indicating that if other soldiers use hand sanitizers, they will refuse to do so. Intervention to ensure use of hand sanitizer should focus on strengthening behavioral and normative beliefs among low intenders. This should increase the overall well being of the military.

    A contingent valuation survey was conducted in Kumasi, Ghana, to estimate households' willingness to pay for two types of improved sanitation services: improved ventilated pit latrines and water closets connected to a sewer system. Over 1200 randomly selected households throughout the city were interviewed. Most households were willing to pay more for improved sanitation service than they were currently paying for their existing sanitation system (mostly public and bucket latrines), but in absolute terms the potential revenues from households are not large, of the order of US$1.40 per household per month (about 1-2% of household income). The results of the study confirm the conventional wisdom that conventional sewerage is not affordable to the vast majority of households without massive government subsidies. On the other hand, it appears that only modest subsidies are required to achieve relatively high levels of coverage with on-site sanitation (improved ventilated pit latrines). This is because improved ventilated pit latrines are much cheaper than conventional sewerage and because most households are willing to pay about as much for a ventilated pit latrine as for a water closet connected to a sewer. Several tests were conducted to check the accuracy of respondents' answers to contingent valuation questions. The findings indicate that contingent valuation surveys can be successfully carried out in cities in developing countries for public services such as sanitation and that reasonably reliable information can be obtained on household demand for different sanitation technologies.

    2015-01-01

    Parasites have been infecting humans throughout our evolution. However, not all people suffered with the same species or to the same intensity throughout this time. Our changing way of life has altered the suitability of humans to infection by each type of parasite. This analysis focuses upon the evidence for parasites from archaeological excavations at medieval sites across Europe. Comparison between the patterns of infection in the medieval period allows us to see how changes in sanitation, herding animals, growing and fertilizing crops, the fishing industry, food preparation and migration all affected human susceptibility to different parasites. We go on to explore how ectoparasites may have spread infectious bacterial diseases, and also consider what medieval medical practitioners thought of parasites and how they tried to treat them. While modern research has shown the use of a toilet decreases the risk of contracting certain intestinal parasites, the evidence for past societies presented here suggests that the invention of latrines had no observable beneficial effects upon intestinal health. This may be because toilets were not sufficiently ubiquitous until the last century, or that the use of fresh human faeces for manuring crops still ensured those parasite species were easily able to reinfect the population.

  14. Sustainable Community Sanitation for a Rural Hospital in Haiti

    Directory of Open Access Journals (Sweden)

    Jason Jawidzik

    2012-12-01

    Full Text Available A fully sustainable sanitation system was developed for a rural hospital in Haiti. The system operates by converting human waste into biogas and fertilizer without using external energy. It is a hybrid anaerobic/aerobic system that maximizes methane production while producing quality compost. The system first separates liquid and solid human waste at the source to control carbon to nitrogen ratio and moisture content to facilitate enhanced biodegradation. It will then degrade human waste through anaerobic digestion and capture the methane gas for on-site use as a heating fuel. For anaerobic decomposition and methane harvesting a bioreactor with two-stage batch process was designed. Finally, partially degraded human waste is extracted from the bioreactor with two-stage batch process and applied to land farming type aerobic composter to produce fertilizer. The proposed system is optimized in design by considering local conditions such as waste composition, waste generation, reaction temperature, residence time, construction materials, and current practice. It is above ground with low maintenance requirements.

    Ionizing radiation is shown capable of serving as an effective sanitizing treatment improving the sanitary quality of shellfish and providing an increased margin of safety for shellfish consumers. 60Co irradiation of the hard-shelled clam, Mercenaria mercenaria, and the oyster, Crassostrea virginica, significantly reduced virus carriage numbers without unduly affecting shellfish survival rates or desirable organoleptic qualities. A D10 value of 2 kGy was determined for depletion of hepatitis A virus in clams and oysters as measured by in situ hybridization fluorescent foci and cytopathology enumeration methods. A D10 value of 2.4 kGy was determined for depletion of rotavirus SA11 in clams and oysters as measured by a plaque forming unit enumeration method. Study results showed ionizing radiation capable of providing an extra, highly effective safeguard of shellfish sanitary quality when combined with traditional depuration treatment. Data drawn from other studies is introduced which shows D10 values as low as 1.0 kGy effectively eliminate Vibrio cholerae, and V. parahemolyticus, from shellfish

    Sanitation improvement is crucial in saving lives that are lost due to water contamination. Progress towards achieving full sanitation coverage is still slow in low-income informal settlements in most developing countries. Furthermore, resources are being wasted on installing facilities that are later misused or never used because they do not meet the local demand. Understanding demand for improved sanitation in the local context is critical if facilities are to be continually used. Various approaches that attempt to change peoples' behaviours or create demand have been reviewed to identify what they are designed to address. A multi-disciplinary research team using mixed methods is re-emphasised as a comprehensive approach for assessing demand for improved sanitation in low-income informal settlements, where the sanitation situation is more challenging than in other areas. Further research involving a multi-disciplinary research team and use of mixed methods to assess sanitation demand in informal settlements is needed.

  1. Capacity factor analysis for evaluating water and sanitation infrastructure choices for developing communities.

    40% of the world's population lacks access to adequate supplies of water and sanitation services to sustain human health. In fact, more than 780 million people lack access to safe water supplies and about 2.5 billion people lack access to basic sanitation. Appropriate technology for water supply and sanitation (Watsan) systems is critical for sustained access to these services. Current approaches for the selection of Watsan technologies in developing communities have a high failure rate. It is estimated that 30%-60% of Watsan installed infrastructures in developing countries are not operating. Inappropriate technology is a common explanation for the high rate of failure of Watsan infrastructure, particularly in lower-income communities (Palaniappan et al., 2008). This paper presents the capacity factor analysis (CFA) model, for the assessment of a community's capacity to manage and sustain access to water supply and sanitation services. The CFA model is used for the assessment of a community's capacity to operate, and maintain a municipal sanitation service (MSS) such as, drinking water supply, wastewater and sewage treatment, and management of solid waste. The assessment of the community's capacity is based on seven capacity factors that have been identified as playing a key role in the sustainability of municipal sanitation services in developing communities (Louis, 2002). These capacity factors and their constituents are defined for each municipal sanitation service. Benchmarks and international standards for the constituents of the CFs are used to assess the capacity factors. The assessment of the community's capacity factors leads to determine the overall community capacity level (CCL) to manage a MSS. The CCL can then be used to assist the community in the selection of appropriate Watsan technologies for their MSS needs. The selection is done from Watsan technologies that require a capacity level to operate them that matches the assessed CCL of the

    New types of sanitation services are emerging to tackle the sanitation crisis in informal settlements. These services link toilet facilities to semi-decentralized treatment plants via frequent, road-based transport of excreta. However, information for the planning of such sanitation services is scarce, and their future operating conditions are highly uncertain. The key questions of this paper are therefore: a) what are the drivers behind success or failure of a service-based sanitation system in informal settlements and b) on what scales and under which conditions can such a system operate successfully? To answer these questions, already at an early stage of the planning process, we introduce a stochastic model to analyze a wide range of system designs under varying technical designs, socio-economic factors, and spatial condition. Based on these initial results, we design a sanitation service and use the numeric model to study its reliability and costs over a wide range of scales, i.e., system capacities, from very few to many hundred users per semi-decentralized treatment unit. Key findings are that such a system can only operate within a narrow, but realistic range of conditions. Key requirements are toilet facilities, which can be serviced rapidly, and a flexible workforce. A high density of facilities will also lower the costs. Under these premises, we develop a road-based sanitation service and model its functionality in different settings and under many scenarios. Results show that the developed sanitation system using a single vehicle is scalable (100-700 users), can provide reliable service, and can be cheap (settlements and presents a quantitative framework for designing such systems.

    Full Text Available This paper examines the relationship among access to improved water, sanitation and economic growth in Bangladesh through co-integration and vector error correction model (VECM over the period 1991 to 2014. Bangladesh has registered remarkable progress in achieving major Millennium Development Goals (MDG. Today nearly 87% of our total population has access to improved water sources and 60% have access to improved sanitation facilities which is contributing significantly towards human development in Bangladesh. Therefore we want to test whether access to improved water and sanitation accelerates economic growth in Bangladesh through a time series analysis. The Johansen co-integration tests indicate that there is long run association among the variables. The vector error correction model indicates that there is a long run causality running from improved sanitation facilities (% of population with access and improved water source (% of population with access to gross domestic product in Bangladesh. Similarly in the short run a causal relationship has been found among the variables as well. Further impulse response function and variance decomposition results say that improved sanitation facilities (% of population with access and improved water source (% of population with access can explain the major variations in our economic growth. The implication of our findings is that in Bangladesh an increase in improved access to water and sanitation is likely to positively affect our economic growth in the long run. Keeping in mind about Sustainable Development Goals (SDG, policymakers in Bangladesh need to pay special attention to ensure greater access to improved water and sanitation to boost our economic growth & development.

    BACKGROUND/OBJECTIVES The present study investigated Korean and Taiwan adults on the importance of and the satisfaction with street food sanitation and street food choice factor, in order to present management and improvement measures for street foods. SUBJECTS/METHODS The present study conducted a survey on 400 randomly chosen adults (200 Korean, 200 Taiwanese). General characteristics, eating habits, street food intake frequency, and preference by type of street food of respondents were checked. Respondents' importance and satisfaction of street food hygiene and selection attributes were also measured. In order to test for the difference between groups, χ2-test and t-test were performed. ISA was also performed to analyze importance and satisfaction. RESULTS Results showed that the importance of sanitation was significantly higher than satisfaction on all items in both Korea and Taiwan, and the satisfaction with sanitation was higher in Taiwan than in Korea. According to ISA results with street food sanitation, satisfaction was low while importance was high in both Korea and Taiwan. In terms of street food choice factor, importance scores were significantly higher than satisfaction scores on all items. In addition, satisfaction scores on all items except 'taste' were significantly higher in Taiwan than in Korea. CONCLUSIONS A manual on sanitation management of street foods should be developed to change the knowledge and attitude toward sanitation by putting into practice a regularly conducted education. Considering the popularity of street foods and its potential as a tourism resource to easily publicize our food culture, thorough management measures should be prepared on sanitation so that safe street food culture should be created.

    Open defecation is practiced by more than one billion people throughout the world and leads to significant public health issues including infectious disease transmission and stunted growth in children. Zambia implemented community-led total sanitation (CLTS) as an intervention to eliminate open defecation in rural areas. To support CLTS and the attainment of open defecation free communities, chiefs were considered key agents of change and were empowered to drive CLTS and improve sanitation for their chiefdom. Chiefs were provided with data on access to sanitation in the chiefdom during chiefdom orientations prior to the initiation of CLTS within each community and encouraged to make goals of universal sanitation access within the community. Using a survival regression, we found that where chiefs were orientated and mobilized in CLTS, the probability that a village would achieve 100% coverage of adequate sanitation increased by 23% (hazard ratio = 1.263, 95% confidence interval = 1.080-1.478, P = 0.003). Using an interrupted time series, we found a 30% increase in the number of individuals with access to adequate sanitation following chiefdom orientations (95% confidence interval = 28.8-32.0%). The mobilization and support of chiefs greatly improved the uptake of CLTS, and empowering them with increased CLTS knowledge and authority of the program in their chiefdom allowed chiefs to closely monitor village sanitation progress and follow-up with their headmen/headwomen. These key agents of change are important facilitators of public health goals such as the elimination of open defecation in Zambia by 2020.

    Nosocomial infections are a major problem in health care facilities, resulting in extended durations of care, substantial morbidity and mortality, and excess costs. Since alcohol gel hand sanitizers combine high immediate antimicrobial efficacy with ease of use, this study was carried out to determine the effect of the use of an alcohol gel hand sanitizer by caregivers on infection types and rates in an acute care facility. Patients were educated about the study through a poster on the unit, and teachable patients were given portable bottles of the alcohol hand gel for bedside use, along with an educational brochure explaining how and why to practice good hand hygiene. Infection rate and type data were collected in 1 unit of a 498-bed acute care facility for 16 months (February 2000 to May 2001). An alcohol gel hand sanitizer was provided and used by caregivers in the orthopedic surgical unit of the facility during this period. The primary infection types (more than 80%) found were urinary tract (UTI) and surgical site (SSI) infections. Infection types and rates for the unit during the period the alcohol hand sanitizer (intervention) was used were compared with the infection types and rates for the same unit when the alcohol hand sanitizer was not used (baseline); the results demonstrated a 36.1% decrease in infection rates for the 10-month period that the hand sanitizer was used. This study indicates that use of an alcohol gel hand sanitizer can decrease infection rates and provide an additional tool for an effective infection control program in acute care facilities.

    To evaluate the antimicrobial efficacy of four different hand sanitizers against Staphylococcus aureus , Staphylococcus epidermidis , Pseudomonas aeruginosa , Escherichia coli , and Enterococcus faecalis as well as to assess and compare the antimicrobial effectiveness among four different hand sanitizers. The present study is an in vitro study to evaluate antimicrobial efficacy of Dettol, Lifebuoy, PureHands, and Sterillium hand sanitizers against clinical isolates of the aforementioned test organisms. The well variant of agar disk diffusion test using Mueller-Hinton agar was used for evaluating the antimicrobial efficacy of hand sanitizers. McFarland 0.5 turbidity standard was taken as reference to adjust the turbidity of bacterial suspensions. Fifty microliters of the hand sanitizer was introduced into each of the 4 wells while the 5 th well incorporated with sterile water served as a control. This was done for all the test organisms and plates were incubated in an incubator for 24 h at 37΀C. After incubation, antimicrobial effectiveness was determined using digital caliper (mm) by measuring the zone of inhibition. The mean diameters of zones of inhibition (in mm) observed in Group A (Sterillium), Group B (PureHands), Group C (Lifebuoy), and Group D (Dettol) were 22 ± 6, 7.5 ± 0.5, 9.5 ± 1.5, and 8 ± 1, respectively. Maximum inhibition was found with Group A against all the tested organisms. Data were statistically analyzed using analysis of variance, followed by post hoc test for group-wise comparisons. The difference in the values of different sanitizers was statistically significant at P hand sanitizer to maintain the hand hygiene.

    Mwendera, E. J.

    An assessment of rural water supply and sanitation (RWSS) coverage in Swaziland was conducted in 2004/2005 as part of the Rural Water Supply and Sanitation Initiative (RWSSI). The initiative was developed by the African Development Bank with the aim of implementing it in the Regional Member Countries (RMCs), including Swaziland. Information on the RWSS sector programmes, costs, financial requirements and other related activities was obtained from a wide range of national documents, including sector papers and project files and progress reports. Interviews were held with staff from the central offices and field stations of Government of Swaziland (GOS) ministries and departments, non-governmental organizations (NGOs), bilateral and multilateral external support agencies, and private sector individuals and firms with some connection to the sector and/or its programmes. The assessment also involved field visits to various regions in order to obtain first hand information about the various technologies and institutional structures used in the provision of water supplies and sanitation services in the rural areas of the country. The results showed that the RWSS sector has made significant progress towards meeting the national targets of providing water and sanitation to the entire rural population by the year 2022. The assessment indicated that rural water supply coverage was 56% in 2004 while sanitation coverage was 63% in the same year. The results showed that there is some decline in the incidence of water-related diseases, such as diarrhoeal diseases, probably due to improved water supply and sanitation coverage. The study also showed that, with adequate financial resources, Swaziland is likely to achieve 100% coverage of both water supply and sanitation by the year 2022. It was concluded that in achieving its own national goals Swaziland will exceed the Millennium Development Goals (MDGs). However, such achievement is subject to adequate financial resources being

    Full Text Available Resolution A/HRC/RES/16/2 adopted by the UN Human Rights Council on 8 April 2011 declared access to safe drinking water and sanitation a human right. However many people around the globe including people with disabilities do not have access to safe drinking water, hygiene or sanitation facilities. Inaccessibility of clean water sources, hygiene and sanitation facilities negatively impacts among others health, education, the ability to work, and the ability to partake in social activities. This paper looks at the benefits of, and access barriers to, clean water and sanitation for people with disabilities.

  12. A qualitative comparative analysis of well-managed school sanitation in Bangladesh

    Background Continued management of sanitation and hygiene services, post-intervention, is a global challenge, particularly in the school-setting. This situation threatens anticipated impacts of school sanitation and hygiene investments. To improve programming and policies, and increase the effectiveness of limited development resources, we seek to understand how and why some schools have well-managed sanitation post-intervention, while others do not. Methods Based on in-depth qualitative data from 16 case schools in Meherpur, Bangladesh, we employ fuzzy-set qualitative comparative analysis to identify the necessary and sufficient conditions, or combinations of conditions (referred to as pathways), that lead to either well-managed or poorly managed school sanitation. We include posited sustainability determinants from the literature and factors that emerged from the cases themselves in the analysis. Results We identified three distinct pathways sufficient to support well-managed services, providing multiple options for how well-managed school sanitation could be encouraged. Two of these are applicable to both government and non-government schools: (1) quality construction, financial community support and a champion; and (2) quality construction, financial government support, a maintenance plan and school management committee involvement. On-going financial support for operations and maintenance was identified as a necessary condition for continued service management, which was absent from many schools with poorly managed services. However, financial support was insufficient alone and other conditions are needed in conjunction, including quality construction and incentivizing conditions, such as school management committee involvement in sanitation specifically, a sanitation champion, and/or one teacher clearly responsible for toilet maintenance. Surprisingly, the number of students per toilet (ranging from 18–95 students) and toilet age (ranging from 8–32

    International monitoring of drinking water and sanitation shapes awareness of countries’ needs and informs policy, implementation and research efforts to extend and improve services. The Millennium Development Goals established global targets for drinking water and sanitation access; progress towards these targets, facilitated by international monitoring, has contributed to reducing the global disease burden and increasing quality of life. The experiences of the MDG period generated important lessons about the strengths and limitations of current approaches to defining and monitoring access to drinking water and sanitation. The methods by which the Joint Monitoring Programme (JMP) of WHO and UNICEF tracks access and progress are based on analysis of data from household surveys and linear regression modelling of these results over time. These methods provide nationally-representative and internationally-comparable insights into the drinking water and sanitation facilities used by populations worldwide, but also have substantial limitations: current methods do not address water quality, equity of access, or extra-household services. Improved statistical methods are needed to better model temporal trends. This article describes and critically reviews JMP methods in detail for the first time. It also explores the impact of, and future directions for, international monitoring of drinking water and sanitation. PMID:25116635

    The microbial quality of eggs entering the hatchery is an important critical control point for biosecurity, pathogen reduction, and food safety programs in poultry production. Developing interventions to reduce Salmonella contamination of eggs is important to improving the microbial food safety of poultry and poultry products. The hydrogen peroxide (H2O2) and ultraviolet light (UV) Advanced Oxidation Process (AOP) has been previously demonstrated to be effective in reducing Salmonella on the surface of experimentally contaminated eggs. The objective of this study was to evaluate the effect of treating eggs with an egg-sanitizing apparatus using the H2O2/UV AOP on Salmonella contamination during incubation, hatching, and in broiler chicks during grow-out. Experimentally contaminated eggs were treated using the automated H2O2/UV AOP egg sanitizer and incubated for 21 d. AOP sanitization reduced Salmonella up to 7 log10 cfu egg-1 (P Salmonella positive eggs by up to 75% (P Salmonella-positive eggs during incubation. Additionally, Salmonella was recovered from more chicks hatched from untreated eggs than from eggs treated using the H2O2/UV AOP egg sanitizer (P Salmonella contamination on the surface of eggs using the H2O2/UV AOP egg sanitizer prior to incubation may reduce the gastrointestinal colonization of chicks by Salmonella. © 2017 Poultry Science Association Inc.

    The lack of proper water and sanitation infrastructures and poor hygiene practices in health-care facilities reduces facilities' preparedness and response to disease outbreaks and decreases the communities' trust in the health services provided. To improve water and sanitation infrastructures and hygiene practices, the Liberian health ministry held multistakeholder meetings to develop a national water, sanitation and hygiene and environmental health package. A national train-the-trainer course was held for county environmental health technicians, which included infection prevention and control focal persons; the focal persons acted as change agents. In Liberia, only 45% of 701 surveyed health-care facilities had an improved water source in 2015, and only 27% of these health-care facilities had proper disposal for infectious waste. Local ownership, through engagement of local health workers, was introduced to ensure development and refinement of the package. In-county collaborations between health-care facilities, along with multisectoral collaboration, informed national level direction, which led to increased focus on water and sanitation infrastructures and uptake of hygiene practices to improve the overall quality of service delivery. National level leadership was important to identify a vision and create an enabling environment for changing the perception of water, sanitation and hygiene in health-care provision. The involvement of health workers was central to address basic infrastructure and hygiene practices in health-care facilities and they also worked as stimulators for sustainable change. Further, developing a long-term implementation plan for national level initiatives is important to ensure sustainability.

    Diarrhoea diseases are among the leading causes of morbidity and mortality in under-five-children (U-5C) in Nigeria. Inadequate safe water, sanitation, and hygiene account for the disease burden. Cases of diarrhoea still occur in high proportion in the study area despite government-oriented interventions. To determine the hygiene and sanitation risk factors predisposing U-5C to diarrhoea in Ibadan, Nigeria. Two hundred and twenty pairs of children, matched on age, were recruited as cases and controls over a period of 5 months in Ibadan. Questionnaire and observation checklist were used to obtain information on hygiene practices from caregivers/mothers and sanitation conditions in the households of 30% of the consenting mothers/caregivers. Data were analysed using descriptive and inferential statistics. Caregivers/mothers' mean ages were 31.3 ±7.5 (cases) and 30.6 ±6.0(controls) years. The risk of diarrhoea was significantly higher among children whose mothers did not wash hands with soap before food preparation (OR=3.0, pHygiene and sanitation conditions within households were risk factors for diarrhoea. This study revealed the feasibility of developing and implementing an adequate model to establish intervention priorities in sanitation in Ibadan, Nigeria.

    Full Text Available Strawberries, cherry tomatoes, and red bayberries, which are the most popular types of fresh produce in China, are vulnerable to microbial contamination. In this study, different sanitizing methods [treatment with 2% organic acids, 0.02% sodium hypochlorite (SH, 0.1% sodium chlorite (SC, and 0.1% acidified sodium chlorite (ASC] were applied to fresh strawberry, cherry tomato, and red bayberry, and their abilities to reduce aerobic bacteria, Escherichia coli O157:H7, mold, yeast, and Salmonella Typhimurium were evaluated. The commercially used SH method reduced the background microbiota on strawberry, cherry tomato, and red bayberry by 0.20–2.07 log cfu/g. The ASC method reduced background microbiota (except for mold on strawberry and cherry tomato by more than 3.0 log cfu/g. ASC was the only sanitizer that significantly reduced mold on red bayberry, and lactic acid was the only organic acid sanitizer that effectively reduced yeast on red bayberry. The ASC method had the best sterilizing effect on the three fresh fruits and also required the shortest sanitizing time and low chlorite content. The application of ASC method significantly reduced the microbiota on retail grocery samples, and the effect was similar to that achieved by sanitizing methods comparison.

    Access to sanitation technologies remains one of the biggest challenges in sub-Saharan Africa. To overcome this gap, a sanitation project called “Ameli-EAUR” translated from French as improvement of water and sanitation in urban and rural areas, was implemented in Burkina Faso for 5 years (2010-2016). The technologies from the project were designed on the basis of agro-sanitation concept, leading to package containing a composting toilet, a grey water treatment facility and a set of urine collection and treatment. The study aimed to evaluate of Ameli-EAUR project, one year after the end, and identify some key factors of sustainability of technologies. As methodology, a survey and a technical diagnostic of implemented technologies were done. The results showed that, the pilot families stopped using all the technologies one year after the end of the project. However, two main lessons can be learnt: (1) in term of efficiency and effectiveness of the project the technology of composting toilet was not robust enough, leading to a rapid abandonment after the project (2) in term of impact and sustainability, the economic incentive of the resource oriented sanitation concept was very weak compared to the needed workload. The technologies development in this kind of project should be carried on and associated with a more inclusive system driven by economic incentive.

    Background: Large proportions of people still do not have excess to safe drinking water and proper sanitation. Methods: Qualitative and quantitative approaches were used to assess the health impacts. Random households were selected. Information was collected from questionnaire through interview schedule method, group discussion and observation checklist. Results: People rated water and sanitation condition in urban as: 10% very good, 27% good, 20% bad, 43% very bad, and none of them said we don't know. While in rural areas they rated 10% very good, 36% good, 44% bad, 6% very bad, and 4% of them said we don't know. Water sources in selected urban and rural areas were different, 37% in urban and 68% in rural area depended on bore wells as water source, 22% depended on hand pumps. In urban areas, the disease ratio was typhoid 20%, hepatitis 13%, diarrhoea 27%, skin infection 23%, stomach problems 53% and allergies 33%. In rural areas, after stomach problems, diarrhoea, hepatitis and typhoid ratio was very high as compared to urban area. In rural community, 70% were unaware of poor water and sanitation consequences on health. Conclusion: The water and sanitation condition in urban as well as in rural community is poor but in rural community it is even worse. The drinking water was contaminated with E. coli, Enterobacter, Salmonella and Clostridium. This observation was correlated with prevalence of many water born diseases especially in rural communities of Abbottabad. and sanitation. (author)

    In collaboration with Public Health Practice-Based Research Networks, we investigated relationships between local health department (LHD) food safety and sanitation expenditures and reported enteric disease rates. We combined annual infection rates for the common notifiable enteric diseases with uniquely detailed, LHD-level food safety and sanitation annual expenditure data obtained from Washington and New York state health departments. We used a multivariate panel time-series design to examine ecologic relationships between 2000-2010 local food safety and sanitation expenditures and enteric diseases. Our study population consisted of 72 LHDs (mostly serving county-level jurisdictions) in Washington and New York. While controlling for other factors, we found significant associations between higher LHD food and sanitation spending and a lower incidence of salmonellosis in Washington and a lower incidence of cryptosporidiosis in New York. Local public health expenditures on food and sanitation services are important because of their association with certain health indicators. Our study supports the need for program-specific LHD service-related data to measure the cost, performance, and outcomes of prevention efforts to inform practice and policymaking.

    Objectives. In collaboration with Public Health Practice–Based Research Networks, we investigated relationships between local health department (LHD) food safety and sanitation expenditures and reported enteric disease rates. Methods. We combined annual infection rates for the common notifiable enteric diseases with uniquely detailed, LHD-level food safety and sanitation annual expenditure data obtained from Washington and New York state health departments. We used a multivariate panel time-series design to examine ecologic relationships between 2000–2010 local food safety and sanitation expenditures and enteric diseases. Our study population consisted of 72 LHDs (mostly serving county-level jurisdictions) in Washington and New York. Results. While controlling for other factors, we found significant associations between higher LHD food and sanitation spending and a lower incidence of salmonellosis in Washington and a lower incidence of cryptosporidiosis in New York. Conclusions. Local public health expenditures on food and sanitation services are important because of their association with certain health indicators. Our study supports the need for program-specific LHD service-related data to measure the cost, performance, and outcomes of prevention efforts to inform practice and policymaking. PMID:25689186

    Over 1 billion people still practice open defecation. Low uptake and use of new sanitation technologies in a number of settings has underscored our current limited understanding of the complex attitudinal factors that influence a household's decision to adopt and use new sanitation technologies. Mokken scaling techniques were applied to series of population-based surveys in Odisha, India between September 2011 and October 2013 (sample sizes 120, 500, 2200). Surveys contained simple, agree/disagree statements about attitudes toward sanitation use and sanitation technologies. Analysis produced two scales-a 10-question General Scale, reflecting attitudes toward defecation and norms regarding latrine use for all respondents, and a 6-question Experiential Scale, reflecting personal experiences with and perceived convenience of sanitation technologies targeted at respondents with a latrine. Among all respondents, a one-point change in the General Scale was associated with a 5-percentage point change in the marginal probability of having access to a functioning latrine. Among respondents with a functional latrine at home, a one-point increase in the General and Experiential Scales were associated with a 4- and 8-percentage point decrease in the probability of engaging in any open defecation in the last 7 days, respectively.

    The use of hand sanitizer is effective in preventing the transmission of disease. Many hand sanitizers are alcohol-based, and significant intoxications have occurred, often in health care facilities, including the emergency department (ED). We present this case to highlight potential toxicity after the ingestion of an ethanol-based hand sanitizer. A 36-year-old man presented to the ED with ethanol intoxication. Ethanol breath analysis was measured at 278 mg/dL. After 4 h, the patient was less intoxicated and left the ED. Thirty minutes later, he was found apneic and pulseless in the ED waiting room bathroom after having ingested an ethanol-based hand sanitizer. Soon after a brief resuscitation, his serum ethanol was 526 mg/dL. He never regained consciousness and died 7 days later. No other cause of death was found. The case highlights the potential for significant toxicity after the ingestion of a product found throughout health care facilities. Balancing the benefit of hand sanitizers for preventing disease transmission and their potential misuse remains a challenge. Copyright © 2013 Elsevier Inc. All rights reserved.

    2011-01-01

    The Middle East and North Africa (MENA) is generally considered to be making adequate progress towards meeting Target 10 of the Millennium Development Goals (MDGs), which calls for halving the proportion of the population with inadequate access to drinking water and sanitation. Progress towards achieving Target 10 is evaluated by the Joint Monitoring Programme (JMP), run by UNICEF and WHO. This article shows that the assessment methodologies employed by the JMP significantly overstate coverage rates in the drinking water and sanitation sectors, by overlooking and ‘not counting’ problems of access, affordability, quality of service and pollution. The authors show that states in MENA often fail to provide safe drinking water and adequate sanitation services, particularly in densely populated informal settlements, and that many centralized water and sanitation infrastructures contribute to water pollution and contamination. Despite the glaring gap between the MDG statistics and the evidence available from national and local reports, exclusionary political regimes in the region have had few incentives to adopt more accurate assessments and improve the quality of service. While international organizations have proposed some reforms, they too lack incentives to employ adequate measures that gauge access, quality and affordability of drinking water and sanitation services.

    2018-04-01

    We conducted a cross sectional study to assess 1) the association between access to basic sanitation and fecal contamination of sentinel toy balls and 2) if other sanitation factors such as shared use and cleanliness are associated with fecal contamination of sentinel toy balls. We assessed sanitation facilities in 454 households with a child aged 6-24 months in rural Bangladesh. We defined "basic" sanitation as access to improved sanitation facilities (pit latrine with a slab or better) not shared with other households. In each household, an identical toy ball was given to the target child. After 24 hours, the balls were rinsed to enumerate fecal coliforms as an indicator of household fecal contamination. Households with basic sanitation had lower fecal coliform contamination than households with no access to basic sanitation (adjusted difference in means: -0.31 log 10 colony forming units [CFU]/toy ball; 95% confidence interval [CI]: -0.61, -0.01). Shared sanitation facilities of otherwise improved type were more likely to have visible feces on the latrine slab compared with private facilities. Among households with access to improved sanitation, households with no visible feces on the latrine slab had less toy ball contamination than households with visible feces on the latrine slab (adjusted difference in means: -0.38 log 10 CFU/toy ball; 95% CI: -0.77, 0.02). Access to basic sanitation may prevent fecal contamination of the household environment. An Improved sanitation facility used by an individual household may be better in preventing household fecal contamination compared with improved facilities shared with other households.

  9. Sanitation practices and perceptions in Kakuma refugee camp, Kenya: Comparing the status quo with a novel service-based approach.

    Directory of Open Access Journals (Sweden)

    Raymond Nyoka

    Full Text Available Globally, an estimated 2.5 billion people lack access to improved sanitation. Unimproved sanitation increases the risk of morbidity and mortality, especially in protracted refugee situations where sanitation is based on pit latrine use. Once the pit is full, waste remains in the pit, necessitating the construction of a new latrine, straining available land and funding resources. A viable, sustainable solution is needed. This study used qualitative and quantitative methods to design, implement, and pilot a novel sanitation system in Kakuma refugee camp, Kenya. An initial round of 12 pre-implementation focus group discussions (FGDs were conducted with Dinka and Somali residents to understand sanitation practices, perceptions, and needs. FGDs and a supplementary pre-implementation survey informed the development of an innovative sanitation management system that incorporated the provision of urine and liquid-diverting toilets, which separate urine and fecal waste, and a service-based sanitation system that included weekly waste collection. The new system was implemented on a pilot scale for 6 weeks. During the implementation, bi-weekly surveys were administered in each study household to monitor user perceptions and challenges. At the end of the pilot, the sanitation system was assessed using a second round of four post-implementation FGDs. Those who piloted the new sanitation system reported high levels of user satisfaction. Reported benefits included odor reduction, insect/pest reduction, the sitting design, the appropriateness for special populations, and waste collection. However, urine and liquid diversion presented a challenge for users who perform anal washing and for women who had experienced female genital mutilation. Refugee populations are often culturally and ethnically diverse. Using residents' input to inform the development of sanitation solutions can increase user acceptability and provide opportunities to improve sanitation system

  11. Resource recovery and reuse as an incentive for a more viable sanitation service chain

    Directory of Open Access Journals (Sweden)

    Krishna C. Rao

    2017-06-01

    Full Text Available Recovering nutrients, water and energy from domestic waste streams, including wastewater and faecal sludge, is slowly gaining momentum in low-income countries. Resource recovery and reuse (RRR offers value beyond environmental benefits through cost recovery. An expected game changer in sanitation service provision is a business model where benefits accrued via RRR can support upstream sanitation services despite the multitude of private and public stakeholders involved from waste collection to treatment. This paper shows options of how resource recovery and reuse can be an incentive for the sustainable sanitation service chain, by recovering costs where revenue can feed back internally or using generated revenues from reuse to fill financial gaps across the service chain to complement other supporting mechanisms for making waste management more attractive.

    Waterless alcohol-based hand sanitizers are an increasingly popular method of hand hygiene and help prevent hospital-acquired infection (HAI). Whether hand sanitizer dispensers (HSDs) may themselves harbor pathogens or act as fomites has not been reported. All HSDs in the surgical intensive care unit of an urban teaching hospital were cultured at three sites: The dispenser lever, the rear underside, and the area surrounding the dispensing nozzle. All HSDs yielded one or more bacterial species, including commensal skin flora and enteric gram-negative bacilli. Colonization was greatest on the lever, where there is direct hand contact. Hand sanitizer dispensers can become contaminated with pathogens that cause HAI and thus are potential fomites.

    A device is designed for producing and confining highenergy plasma from which neutrons are generated in copious quantities. A rotating sheath of electrons is established in a radial electric field and axial magnetic field produced within the device. The electron sheath serves as a strong ionizing medium to gas introdueed thereto and also functions as an extremely effective heating mechanism to the resulting plasma. In addition, improved confinement of the plasma is obtained by ring magnetic mirror fields produced at the ends of the device. Such ring mirror fields are defined by the magnetic field lines at the ends of the device diverging radially outward from the axis of the device and thereafter converging at spatial annular surfaces disposed concentrically thereabout.

    Pathogenic microbes on the surfaces of salad crops and growth chambers pose a threat to the health of crew on International Space Station. For astronauts to safely consume spacegrown vegetables produced in NASA's new vegetable production unit, VEGGIE, three technical challenges must be overcome: real-time sampling, microbiological analysis, and sanitation. Raphanus sativus cultivar Cherry Bomb II and Latuca sativa cultivar Outredgeous, two saled crops to be grown in VEGGIE, were inoculated with Salmonella enterica serovar Typhimurium (S. Typhimurium), a bacterium known to cause food-borne illness Tape- and swab-based sampling techniques were optimized for use in microgravity and assessed for effectiveness in recovery of bacteria from crop surfaces: Rapid pathogen detection and molecular analyses were performed via quantitative real-time polymerase chain reactiop using LightCycler® 480 and RAZOR® EX, a scaled-down instrument that is undergoing evaluation and testing for future flight hardware. These methods were compared with conventional, culture-based methods for the recovery of S. Typhimurium colonies. A sterile wipe saturated with a citric acid-based, food-grade sanitizer was applied to two different surface materials used in VEGGIE flight hardware that had been contaminated with the bacterium Pseudomonas aeruginosa,. another known human pathogen. To sanitize surfaces, wipes were saturated with either the sanitizer or sterile deionized water and applied to each surface. Colony forming units of P. aeruginosa grown on tryptic soy agar plates were enumerated from surface samples after sanitization treatments. Depending on the VEGGIE hardware material, 2- to 4.5-log10 reductions in colony-forming units were observed after sanitization. The difference in recovery of S. Typhimurium between tape- and swab- based sampling techniques was insignificant. RAZOR® EX rapidly detected S. Typhimurium present in both raw culture and extracted DNA samples.

    This work presents a study of human hair as a bio-indicator for detection of heavy metals as part of environmental health surveillance programs project to develop a subject of interest in the biomedical and environmental sciences. A total of 34 hair samples were analyzed that consisting of 29 samples from sanitation workers and five samples from students. The hair samples were prepared and treated in accordance to the International Atomic Energy Agency (IAEA) recommendations. The concentrations of heavy metals were analyzed using the energy dispersive X-ray fluorescence (EDXRF) technique by X-50 Mobile X-ray Fluorescence (XRF) at Oceanography Institute, Universiti Malaysia Terengganu. The performance of EDXRF analyzer was tested by Standard Reference Material (SRM 2711) Montana Soil which was in good agreement with certified value within 14% deviations except for Hg. While seven heavy metals: Mn, Fe, Ni, Cu, Zn, Se, and Sb were detected in both groups, three additional elements, i.e. As, Hg and Pb, were detected only in sanitation workers group. For sanitation workers group, the mean concentration of six elements, Mn, Fe, Cu, Zn, Se, and Sb, shows elevated concentration as compared to the control samples concentration. Results from both groups were compared and discussed in relation to their respective heavy metals concentrations. - Highlights: ► We determine heavy metals in hair sample of sanitation workers and control group. ► 7 heavy metals, Mn, Fe, Ni, Cu, Zn, Se, and Sb, were detected in both groups. ► Additional elements of As, Hg and Pb were discovered only in sanitation workers. ► Generally, mean concentration of sanitation workers show elevation in comparison. ► We report results in relation to their respective heavy metals concentrations.

    The objectives of this study were (i) to assess the efficacy of quaternary ammonium chloride-based wet foam (WF) and dry foam (DF) sanitizer systems (600 ppm) for reducing Listeria innocua (a nonpathogenic surrogate of Listeria monocytogenes) or a 100.0 μg/ml rifampin-resistant Salmonella Typhimurium LT2 (a nonpathogenic surrogate of Salmonella enterica serovar Typhimurium) on niche and transfer point areas of an unwashed retail deli slicer as compared with traditional chlorine (Cl(-)) treatment (200 ppm) and (ii) to compare sanitizer surface contact times (10 and 15 min) for pathogen surrogate control. Turkey frankfurter slurries inoculated with L. innocua or Salmonella Typhimurium were used to inoculate seven high-risk sites on a commercial slicer. After 30 min of bacterial attachment, slicers were dry wiped to remove excess food matter, followed by a randomly assigned sanitizer treatment. Surviving pathogen surrogate cells were enumerated on modified Oxford's agar not containing antimicrobic supplement (L. innocua) or on tryptic soy agar supplemented with 100 μg/ml rifampin (Salmonella Typhimurium LT2). Replicate-specific L. innocua and Salmonella Typhimurium reductions were calculated as log CFU per square centimeter of control minus log CFU per square centimeter of enumerated survivors for each site. For both organisms, all sanitizer treatments differed from each other, with Cl(-) producing the least reduction and WF the greatest reduction. A significant (P < 0.05) site-by-treatment interaction was observed. The results of the study indicate that quaternary ammonium chloride sanitizers (600 ppm) applied by both WF and DF were more effective at reducing L. innocua and Salmonella Typhimurium than a traditional Cl sanitizer (200 ppm) on unwashed slicer surfaces.

  20. Sanitation marketing: A systematic review and theoretical critique using the capability approach.

    2017-12-01

    Sanitation is a human right that benefits health. As such, technical and behavioural interventions are widely implemented to increase the number of people using sanitation facilities. These include sanitation marketing interventions (SMIs), in which external support agencies (ESAs) use a hybrid of commercial and social marketing tools to increase supply of, and demand for, sanitation products and services. However, there is little critical discourse on SMIs, or independent rigorous analysis on whether they increase or reduce well-being. Most available information is from ESAs about their own SMI implementation. We systematically reviewed the grey and peer-reviewed literature on sanitation marketing, including qualitatively analysing and calculating descriptive statistics for the parameters measured, or intended to be measured, in publications reporting on 33 SMIs. Guided by the capability approach to development we identified that publications for most SMIs (n = 31, 94%) reported on commodities, whilst fewer reported on parameters related to impacts on well-being (i.e., functionings, n = 22, 67%, and capabilities, n = 20, 61%). When evaluating future SMIs, it may be useful to develop a list of contextualised well-being indicators for the particular SMI's location, taking into account local cultural norms, with this list ideally co-produced with local stakeholders. We identified two common practices in SMIs that can reduce well-being and widen well-being inequalities; namely, the promotion of conspicuous consumption and assaults on dignity, and we discuss the mechanisms by which such impacts occur. We recommend that ESAs understand sanitation marketing's potential to reduce well-being and design SMIs to minimize such detrimental impacts. Throughout the implementation phase ESAs should continuously monitor for well-being impacts and adapt practices to optimise well-being outcomes for all involved. Copyright © 2017.

    To assess whether the joint effects of water and sanitation infrastructure, are acting antagonistically (redundant services preventing the same cases of diarrhoeal disease), independently, or synergistically; and to assess how these effects vary by country and over time. We used data from 217 Demographic and Health Surveys conducted in 74 countries between 1986 and 2013. We used modified Poisson regression to assess the impact of water and sanitation infrastructure on the prevalence of diarrhoea among children under 5. The impact of water and sanitation varied across surveys, and adjusting for socio-economic status drove these estimates towards the null. Sanitation had a greater effect than water infrastructure when all 217 surveys were pooled; however, the impact of sanitation diminished over time. Based on survey data from the past 10 years, we saw no evidence for benefits in improving drinking water or sanitation alone, but we estimated a 6% reduction of both combined (prevalence ratio = 0.94, 95% confidence limit 0.91-0.98). Water and sanitation interventions should be combined to maximise the number of cases of diarrhoeal disease prevented in children under 5. Further research should identify the sources of variability seen between countries and across time. These national surveys likely include substantial measurement error in the categorisation of water and sanitation, making it difficult to interpret the roles of other pathways. © 2014 John Wiley & Sons Ltd.

    Use of alcohol-based hand sanitizer is recommended by the CDC to reduce the risk for travellers' diarrhoea, but its effectiveness has not been assessed. We investigated the potential protective effect of hand sanitizer use on the occurrence of diarrhoea and/or vomiting in 200 international travellers, who were returning home, at an international airport. We also conducted a knowledge, aptitude and practice survey about hand gel use among international travellers consulting for pre-travel advice at a specialized clinic. 200 returning travellers were included of which 32.5% declared having used alcohol-based hand sanitizer during travel. Travellers who used hand sanitizer reported diarrhoea and vomiting significantly less frequently than those who did not (17% vs. 30%, OR = 0.47; 95% CI [0.21-0.97], p = 0.04). A total of 257 travellers consulting for pre-travel advice were included. A majority of travellers knew that hand sanitizer may be used for hand hygiene and had already used hand sanitizer; 72% planned to bring hand sanitizer during their next travel. Use of hand sanitizer is highly acceptable by travellers and is associated with a reduction in the incidence of travellers' diarrhoea and/or vomiting. Copyright © 2014 Elsevier Ltd.

    Cameroon has been fully engaged with the Millennium Development Goals (MDGs) since their inception in 2000. This paper examines the situation of access to potable water and sanitation in Cameroon within the context of the Millennium Development Goals (MDGs), establishes whether Cameroon is on the track of meeting the MDGs in these domains and proposes actions to be taken to bring it closer to these objectives. Based on analyzed data obtained from national surveys, government ministries, national statistical offices, bibliographic research, reports and interviews, it argues that Cameroon will not reach the water and sanitation MGDs. While Cameroon is not yet on track to meet the targets of the MDGs for water and sanitation, it has made notable progress since 1990, much more needs to be done to improve the situation, especially in rural areas. In 2006, 70% of the population had access to safe drinking water and the coverage in urban centres is 88%, significantly better than the 47% in rural areas. However, rapid urbanization has rendered existing infrastructure inadequate with periurban dwellers also lacking access to safe drinking water. Sanitation coverage is also poor. In urban areas only 58% of the population has access to improved sanitation facilities, and the rate in rural areas is 42%. Women and girls shoulder the largest burden in collecting water, 15% of urban and 18% rural populations use improved drinking water sources over 30 minutes away. Cameroon faces the following challenges in reaching the water and sanitation MDGs: poor management and development of the resources, coupled with inadequate political will and commitment for the long term; rapid urbanization; urban and rural poverty and regulation and legislative lapses. The authors propose that: bridging the gap between national water policies and water services; recognizing the role played by Civil Society Organizations (CSOs) in the attainment of MDGs; developing a Council Water Resource Management

    Urine ethyl glucuronide (EtG) is considered as a specific marker of recent ethanol consumption. We describe false-positive DRI(®) EIA EtG enzyme immunoassay results caused by propyl glucuronides in urine after using a propanol-based hand sanitizer. EtG screening was done with the DRI(®) EIA EtG assay (Microgenics), using a cut-off of 0.5 mg/L as recommended by the manufacturer and of 0.1 mg/L as demanded by the German Regulations for Reissuing Drivers Licenses. Confirmatory EtG analysis was done with the ClinMass(®) EtG LC-MS/MS testkit (Recipe), extended by the mass transitions 235.1→75.1, 235.1→85.1, and 235.1→113.1 for the detection of the 1- and 2-propyl glucuronides. Self-experiments were done by staff members of our lab (n=7), using 3 mL Sterillium(®) Classic Pure (30 g/100 g 1-propanol and 45 g/100 g 2-propanol) for hand sanitation every quarter of an hour for 8 h according to DIN EN 1500:2011-05 with and without an exhauster and by passive inhalation of the sanitizer vapor. Spot urine samples were taken immediately before and up to 24 h after the first sanitizer use. False-positive immunoassay results of up to 4 mg/L or 2.3 mg/g creatinine were obtained after normal use of the sanitizer and also after passive inhalation of the sanitizer vapor (up to 0.89 mg/L or 0.61 mg/g). Immunoassay results were positive even after 4-fold use of the sanitizer (up to 0.14 mg/L or 0.38 mg/g) and up to 6 h after the last sanitizer contact (maximum 0.63 mg/L and 0.33 mg/g for sanitizer users and 0.25 mg/g after passive inhalation). Spiking of EtG-free urine with 1-propyl glucuronide (Athena Environmental Sciences) between 0.05 and 10 mg/L clearly demonstrated a cross reaction of the immunoassay of approx. 10% as compared to EtG. LC-MS/MS of urines with a positive immunoassay EtG result did not show EtG signals, but distinct signals of 1-propyl glucuronide (n-propyl glucuronide) and 2-propyl glucuronide (iso-propyl glucuronide). An exhauster effectively prevented

    Ethyl glucuronide (EtG) in urine is considered a specific marker of recent ethanol consumption. There is an ongoing debate about whether inhalation or transdermal resorption of sanitizer ethanol is the underlying cause for positive EtG findings after hand disinfection. Desderman(®) pure (Schülke & Mayr GmbH, Norderstedt) with 78.2g 96% (v/v) ethanol/100g and approx. 10% 2-propanol was used for multiple hand disinfection without and under an exhauster. Simulating a common working day in a clinic, 5 co-workers of our lab used the sanitizer 32 fold within 8h and 2 persons were merely exposed to the sanitizer vapor but without any dermal sanitizer contact. Any additional ethanol intake or exposition was reliably excluded. Spot urine was collected at baseline, after 1, 2, 4, 6 … 14, and finally 24h after the first sanitizer use. A validated LC-MS/MS was used for MRM and MS(3) of EtG and qualitative analyses of ethyl sulfate and 2-propyl glucuronide. Multiple hand disinfection caused positive EtG findings of up to 2.1mg/L or 1.7mg/g creatinine in 4 out of 5 test persons and even of 0.6mg/L or 0.8mg/g for 2 controls which were merely exposed to the sanitizer vapor but without any sanitizer contact. EtG results between the clinical (0.5mg/g) and the forensic (0.1mg/g) cut-off were obtained even 6h after the last sanitizer exposition. An exhauster prevented the sanitizer vapor inhalation and reduced the EtG excretion to mostly below the detection limit of 0.02mg/g. The maximum value was 0.09mg/g. Ethyl sulfate and 2-propyl glucuronide (2-PpG) were detectable only in the EtG positive samples. 2-PpG is a metabolite of 2-propanol, which is quite frequently used in disinfectants. Thus, the detection of this substance can be used in cases of odd EtG results as an indicator of (unintended) sanitizer exposition. Ethanol from hand sanitizers is predominantly incorporated by the respiratory tract but not via the skin. It can cause a distinct ethyl glucuronide excretion and thus

    Background Research suggests that the lived experience of inadequate sanitation may contribute to poor health outcomes above and beyond pathogen exposure, particularly among women. The goal of this research was to understand women’s lived experiences of sanitation by documenting their urination-related, defecation-related and menstruation-related concerns, to use findings to develop a definition of sanitation insecurity among women in low-income settings and to develop a conceptual model to explain the factors that contribute to their experiences, including potential behavioural and health consequences. Methods We conducted 69 Free-List Interviews and eight focus group discussions in a rural population in Odisha, India to identify women’s sanitation concerns and to build an understanding of sanitation insecurity. Findings We found that women at different life stages in rural Odisha, India have a multitude of unaddressed urination, defecation and menstruation concerns. Concerns fell into four domains: the sociocultural context, the physical environment, the social environment and personal constraints. These varied by season, time of day, life stage and toilet ownership, and were linked with an array of adaptations (ie, suppression, withholding food and water) and consequences (ie, scolding, shame, fear). Our derived definition and conceptual model of sanitation insecurity reflect these four domains. Discussion To sincerely address women’s sanitation needs, our findings indicate that more is needed than facilities that change the physical environment alone. Efforts to enable urinating, defecating and managing menstruation independently, comfortably, safely, hygienically, privately, healthily, with dignity and as needed require transformative approaches that also address the gendered, sociocultural and social environments that impact women despite facility access. This research lays the groundwork for future sanitation studies to validate or refine the proposed

    In developing countries, the sanitation and hygiene provision often receives limited resources compared to the water supply. However, water supply benefits tend to diminish if improved sanitation and hygiene are neglected. This paper presents findings of a situational analysis of water supply, sanitation and hygiene infrastructure and their utilization in three primary schools in north-western Botswana. The overall objective of the paper is to determine access and functionality of water supply, sanitation and hygiene infrastructure in three primary schools. The specific objectives are: a) Learners' perspective of their water and sanitation facilities and b) gendered utilization of sanitation and hygiene facilities. Data were collected through a face-to-face administered social survey tool to 286 learners selected through proportionate stratified random sampling from three purposively selected villages in the middle and lower Okavango Delta. Findings indicate that standpipes provide 96% of potable water supply. However, the majority (65% of leaners) indicated that they 'sometimes' experienced water shortage due to dry/nonfunctioning taps/pumps and leaks/wastage. Overall, schools have relatively sufficient sanitation facilities consisting of both water borne toilets and VIP latrines. The major sanitation gap identified was that 80% flush toilets hardly work, while 77% of VIP toilets were in disrepair. Furthermore, poor water supply compromised hand washing with 65.7% learners "always" washing their hands if school standpipes had water, while the majority did not wash hands if standpipes were dry. The study concluded that availability of sanitation infrastructure does not necessarily translate into utilization in the study area due to multiple problems, such as lack of personal hygiene supplies (regular toilet paper and hand washing detergents), privacy issues and recurring water problems. The chronicity of inadequate water, sanitation and hygiene infrastructure in

    A sealing device for minimising the leakage of toxic or radioactive contaminated environments through a biological shield along an opening through which a flexible component moves that penetrates the shield. The sealing device comprises an outer tubular member which extends over a length not less than the maximum longitudinal movement of the component along the opening. An inner sealing block is located intermediate the length of the component by connectors and is positioned in the bore of the outer tubular member to slide in the bore and effect a seal over the entire longitudinal movement of the component. The cross-section of the device may be circular and the block may be of polytetrafluoroethylene or of nylon impregnated with molybdenum or may be metallic. A number of the sealing devices may be combined into an assembly for a plurality of adjacent longitudinally movable components, each adapted to sustain a tensile load, providing the various drives of a master-slave manipulator.

    Sylhet, the northeastern divisional city of Bangladesh, is the major tea-producing region of the country where a large number of low-income workers completely depending on extremely labor-intensive economic activity for their bread and butter, live in and around the tea gardens. The living conditions of these communities are remarkably meager due to the lack of proper utility facilities, especially in water supply and sanitation sectors. A study was conducted at Lakkatura and Ali Bahar Tea Estates to assess the deteriorated sanitation condition of the tea garden workers community and to determine the constraints before the improvement of the condition. It was found that the existing sanitary condition of both of the tea garden slums is very poor because of the same topographical condition and socioeconomic and cultural status of the dwellers. About 50% to 60% tea garden workers still are used to open defecation causing various excreta related diseases and not practiced with washing hand after defecation. Lack of knowledge and awareness about health and hygiene, unwillingness, poverty, superstitions, etc. are responsible for the deteriorated condition of the sanitation system. Based on the analysis, providing latrines free of costs, undertaking extensive motivational and awareness programs and publicity, regular consultation of tea garden workers with the health specialists, and vector control staff of concerned utilities as well as an integrated water supply, sanitation, and hygiene promotion programs should be considered as the priority in order to improve the deteriorated sanitary conditions in two tea gardens.

    Safe drinking water, sanitation, and hygiene (WASH) are fundamental to an improved standard of living. Globally, 91% of households used improved drinking water sources in 2015, while for improved sanitation it is 68%. Wealth disparities are stark, with rural populations, slum dwellers and marginalized groups lagging significantly behind. Service coverage is significantly lower when considering the new water and sanitation targets under the sustainable development goals (SDGs) which aspire to a higher standard of ‘safely managed’ water and sanitation. Lack of access to WASH can have an economic impact as much as 7% of Gross Domestic Product, not including the social and environmental consequences. Research points to significant health and socio-economic consequences of poor nutritional status, child growth and school performance caused by inadequate WASH. Groundwater over-extraction and pollution of surface water bodies have serious impacts on water resource availability and biodiversity, while climate change exacerbates the health risks of water insecurity. A significant literature documents the beneficial impacts of WASH interventions, and a growing number of impact evaluation studies assess how interventions are optimally financed, implemented and sustained. Many innovations in behavior change and service delivery offer potential for scaling up services to meet the SDGs. PMID:27240389

    Following the recent expiry of the United Nations' 2015 Millennium Development Goals (MDGs), new international development agenda covering 2030 water, sanitation and hygiene (WASH) targets have been proposed, which imply new demands on data sources for monitoring relevant progress. This study evaluates drinking-water and sanitation classification systems from national census questionnaire content, based upon the most recent international policy changes, to examine national population census's ability to capture drinking-water and sanitation availability, safety, accessibility, and sustainability. In total, 247 censuses from 83 low income and lower-middle income countries were assessed using a scoring system, intended to assess harmonised water supply and sanitation classification systems for each census relative to the typology needed to monitor the proposed post-2015 indicators of WASH targets. The results signal a lack of international harmonisation and standardisation in census categorisation systems, especially concerning safety, accessibility, and sustainability of services in current census content. This suggests further refinements and harmonisation of future census content may be necessary to reflect ambitions for post-2015 monitoring.

    Full Text Available Terra Preta Sanitation (TPS plays a key role in sustainable sanitation (SuSan and in the sustainable management of resources such as water, energy, soil (agriculture, liquid and solid organic waste streams as well as in the development of sustainable urban environment and infrastructure systems. This paper discusses the advantages of, and requirements for, SuSan systems, focusing on TPS. Case studies showing the stepwise extension and re-development of conventional sanitation systems (CSS using TPS technologies and system approaches are presented and discussed. Decentralized TPS systems integrated in sustainable urban resource management were implemented in the German cities of Hamburg and Berlin. The compilation of best practice examples and findings using the newest TPS systems illustrates the immense potential of this approach for the transformation from conventional to SuSan systems. For this purpose, the potential savings of drinking water resources and the recycling potential of nutrient components are quantified. The results strongly suggest the need to encourage the development and application of innovative decentralized sanitation technologies, urban infrastructures, and resource management systems that have TP as a key component.

Norms every society has the right to get clean air to meet basic daily needs. One of the points in the goal of sustainable development goals (SDGs) in the environment sector is the guarantee of the community to achieve universal access to clean water and sanitation. The SDG High Level Panel held in 2012 calls on countries around the world to do so in 2030. Fulfillment of clean air and sanitation in Indonesia is conducted through two sectoral approaches, the first through agencies, or related agencies and the second through a Society. In accordance with its community-based principles, the role itself is a key factor in the success of the program. Therefore, the purpose of this paper is to find out the forms of community participation and the factors that influence participation in community-based water supply and sanitation programs in the field of literature studies of previous research such as research journals, theses, theses, dissertations and related books This literature study topic.

    Large proportions of people still do not have excess to safe drinking water and proper sanitation. Qualitative and quantitative approaches were used to assess the health impacts. Random households were selected. Information was collected from questionnaire through interview schedule method, group discussion and observation checklist. People rated water and sanitation condition in urban as: 10% very good, 27% good, 20% bad, 43% very bad, and none of them said we don't know While in rural areas they rated 10% very good, 36% good, 44% bad, 6% very bad, and 4% of them said we don't know. Water sources in selected urban and rural areas were different. 37% in urban and 68% in rural area depended on bore wells as water source, 22% depended on hand pumps. In urban areas, the disease ratio was typhoid 20%, hepatitis 13%, diarrhoea 27%, skin infection 23%, stomach problems 53% and allergies 33%. In rural areas, after stomach problems, diarrhoea, hepatitis and typhoid ratio was very high as compared to urban area. In rural community, 70% were unaware of poor water and sanitation consequences on health. The water and sanitation condition in urban as well as in rural community is poor but in rural community it is even worse The drinking water was contaminated with E. coli, Enterobacter, Salmonella and Clostridium. This observation was correlated with prevalence of many water born diseases especially in rural communities of Abbottabad.

    Full Text Available It is known that sporulated bacteria produce proteolytic and lipolytic thermoresistant enzymes associated with technological problems such as off-flavors, age gelation and bitter taste in milk and dairy products. Preventive measures to avoid contamination of milk must be taken in consideration, e.g., the employment of a certain type of sanitizing agent, its conditions of use, concentration, contact time and temperature. The aim of this work was to evaluate the sanitation efficiency of workers of the dairy industry in relation to sporulated bacteria isolated from UHT milk. The suspension test was used to evaluate the efficiency of solutions of sodium hypocholite, biguanide, peracetic acid and hydrogen peroxide against 18 strains of Bacillus sp. isolated from whole UHT milk. Although the biguanide resulted in significant decimal reduction, none of the sanitizing agents studied was effective under the evaluated conditions. The average decimal reduction values obtained were below 5 log cycles (99.999%. The effectiveness of the sanitizing agent is a primary factor in order to control the contaminations within the dairy industry. Thus, it is essential to define the ideal conditions of use of these agents.

    During environmental monitoring of our institution's rodent watering systems, one vivarium was found to have high bacterial loads in the reverse-osmosis (RO) automatic water system. These findings prompted evaluation of the entire RO water production and distribution system. Investigation revealed insufficient rack and RO system sanitization, leading to heavy biofilm accumulation within the system. Approximately 2 wk after discovery in the water system, one of the bacterial organisms isolated in the water supply, Sphingomonas paucimobilis, was isolated from a peritoneal abscess of a severely immunodeficient B6.Cg-Slc11a1r Rag1tm1Mom/Cwi mouse housed in the same vivarium, suggesting that rodents drinking from this system were being exposed randomly to fragments of biofilm. Plans were developed to sanitize the entire system. Hypercholorination was used first, followed by treatment with a combination of peracetic acid and hydrogen peroxide. Between system sanitizations, a low-level chlorine infusion was added to the system as a biocide. Heterotrophic plate counts and bacterial isolation were performed on water samples obtained before and after sanitization procedures. We here discuss the process of identifying and correcting this important water-quality issue. PMID:23562105

    Problems of the environment and of domestic hygiene are always related to poverty of population and the sanitation of settlements. Most cities and towns in developing countries, like India, are characterised by over-crowding, congestion, inadequate water supply and inadequate facilities of disposal of human excreta, waste water and solid wastes. Inadequacy of housing for most urban poor invariably leads to poor home hygiene. Personal and domestic hygiene practices cannot be improved without improving basic amenities, such as water supply, waste water disposal, solid waste management and the problems of human settlements. But even under the prevailing conditions, there is significant scope of improving hygiene practices at home to prevent infection and cross-infection. Unfortunately, in developing countries, public health concerns are usually raised on the institutional setting, such as municipal services, hospitals, environmental sanitation, etc. There is a reluctance to acknowledge the home as a setting of equal importance along with the public institutions in the chain of disease transmission in the community. Managers of home hygiene and community hygiene must act in unison to optimise return from efforts to promote public health. Current practices and perceptions of domestic and personal hygiene in Indian communities, the existing levels of environmental and peri-domestic sanitation and the 'health risk' these pose will be outlined, as well as the need for an integrated action for improving hygiene behaviour and access to safe water and sanitation.

    To assess progress in the provision of drinking water and sanitation in relation to national socioeconomic indicators. We used household survey data for 73 countries - collected between 2000 and 2012 - to calculate linear rates of change in population access to improved drinking water (n = 67) and/or sanitation (n = 61). To enable comparison of progress between countries with different initial levels of access, the calculated rates of change were normalized to fall between -1 and 1. In regression analyses, we investigated associations between the normalized rates of change in population access and national socioeconomic indicators: gross national income per capita, government effectiveness, official development assistance, freshwater resources, education, poverty, Gini coefficient, child mortality and the human development index. The normalized rates of change indicated that most of the investigated countries were making progress towards achieving universal access to improved drinking water and sanitation. However, only about a third showed a level of progress that was at least half the maximum achievable level. The normalized rates of change did not appear to be correlated with any of the national indicators that we investigated. In many countries, the progress being made towards universal access to improved drinking water and sanitation is falling well short of the maximum achievable level. Progress does not appear to be correlated with a country's social and economic characteristics. The between-country variations observed in such progress may be linked to variations in government policies and in the institutional commitment and capacity needed to execute such policies effectively.

    2015-01-01

    Full Text Available In an urban area, the water is supplied through centralised municipal tap water system. For the present enquiry, the municipal supply of water for drinking and sanitation purposes has been assessed in terms of its availability and accessibility to the people, possible sources of water contamination and related health issues in Kolkata. The relevant data have been accessed from various secondary sources where the published data from West Bengal Pollution Control Board (WBPCB and Kolkata Municipal Corporation (KMC are noteworthy. The data thus obtained have been assessed qualitatively to depict the ground reality on sanitation and health related issues. The analyses of the data reveal that in Kolkata, the availability of good quality drinking water is not sufficient as the supply is low and inadequate. On the other hand, the underground water which is considered as the alternative source to the people is found to be contaminated with heavy metals like arsenic and lead. The non-availability of sufficientwater for drinking and sanitation purposes and consumption of contaminated water mayresult into poor health condition with various water borne diseases. The data on diseases from dispensaries (aided by KMC in Kolkata has revealed that people with water borne diseases are significant in number where they are found to be affected with diseases like Acute Diarrhoeal Infection and Dysenteries. Some suitable measures have been proposed whereby applying those, the availability and accessibility of water for drinking and proper sanitation could be enhanced and the occurrences of diseases might be avoided.

    The adoption of principles of equality and universality stipulated in legislation for the sanitation sector requires discussions on innovation. The existing model was able to meet sanitary demands, but was unable to attend all areas causing disparities in vulnerable areas. The universal implementation of sanitation requires identification of the know-how that promotes it and analysis of the model adopted today to establish a new method. Analysis of how different viewpoints on the restructuring process is necessary for the definition of public policy, especially in health, and understanding its complexities and importance in confirming social practices and organizational designs. These are discussed to contribute to universal implementation of sanitation in urban areas by means of a review of the literature and practices in the industry. By way of conclusion, it is considered that accepting a particular concept or idea in sanitation means choosing some effective interventions in the network and on the lives of individual users, and implies a redefinition of the space in which it exercises control and management of sewerage networks, such that connected users are perceived as groups with different interests.

    Improving access to sanitation is a global public health priority. Sufficient consumer demand is required for sanitation coverage to expand through private provision. To measure consumer demand for hygienic latrine platform products in rural Tanzania, we conducted a randomized, voucher-based real-money sales trial with 1638 households with unimproved latrines. We also evaluated multiple supply chain options to determine the costs of supplying latrine platform products to rural households. For concrete latrine SanPlats, 60% of households were willing to pay US$0.48 and 10% of households were willing to pay US$4.05, yet the average cost of supplying the SanPlat to households was US$7.51. Similarly, for plastic sanitary platforms, willingness-to-pay (WTP) dropped from almost 60% at a price of US$1.43 to 5% at a price of US$12.29, compared to an average supply cost of US$23.28. WTP was not significantly different between villages that had participated in the National Sanitation Campaign and those that had not. Randomized informational interventions, including hygiene data-sharing and peer-based exposure to latrine platform products, had minimal effects on WTP. In conclusion, current household demand for latrine platform products is too low to achieve national goals for improved sanitation coverage through fully commercial distribution.

  15. Silver nanoparticles: an alternative method for sanitization of minimally processed cabbage

    2015-06-01

    Full Text Available The minimal processing of vegetables basically aims to extend food shelf life, which depends on a number of factors, such as sanitization, that is considered a critical step for food microbiological quality. However, the usual antimicrobial agents reduce the microbial population in a maximum of two logarithmic cycles. Therefore, it is necessary to develop alternative sanitizers. This study aimed to increase the innocuity of minimally processed cabbage through sanitization with silver nanoparticles. It was observed that the nanoparticles promoted three logarithmic reductions, i.e. a 99.9 % reduction rate, in the Escherichia coli population inoculated on the cabbage surface. When compared to other antimicrobial agents (sodium dichloroisocyanurate and sodium hypochlorite, the nanoparticles were more efficient in sanitizing minimally processed cabbage, showing a lower count of aerobic mesophils. It was also observed that the cabbage surface presents hydrophobic characteristics, resulting in a higher propension for bacterial adhesion, which was confirmed in the thermodynamic evaluation of favorable adhesion for Staphylococcus aureus, Escherichia coli and Listeria innocua.

    Full Text Available The United Nations Sustainable Development Goals (SDGs, announced in September 2015, present a vision of achieving a higher level of human health and well-being worldwide by the year 2030. The SDG targets specific to water and sanitation call for more detailed monitoring and response to understand the coverage and quality of safely managed sources. It is hoped that improved monitoring of water and sanitation interventions will reveal more cost-effective and efficient ways of meeting the SDGs. In this paper, we review the landscape of approaches that can be used to support and improve on the water and sanitation targets SDG 6.1, “By 2030, achieve universal and equitable access to safe and affordable drinking water for all”, and SDG 6.2, “By 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations”.

    Examination of ventilated rat racks prior to semiannual sanitation revealed silicone nozzles and ventilation ports that were partially or completely occluded with granular debris. We subsequently sought to document performance standards for rack sanitation and investigate the effect of ventilation port occlusion on rack function and animal husbandry practices. We hypothesized that individually ventilated cages with occluded airflow would require more frequent cage changes, comparable to those for static cages (that is, every 3 to 4 d). Sprague-Dawley rats were housed under one of 4 conditions: no airflow occlusion, occluded air-supply inlet, occluded air-exhaust outlet, and occlusion of both inlet and outlet. Cages were changed when daily ammonia concentration exceeded 20 ppm or after 14 d had elapsed. Most cages with unoccluded or partial airflow occlusion remained below the 20 ppm limit until day 12 or 13. Cages with occlusion of both inlet and outlet exceeded 20 ppm ammonia by as early as day 5. Airflow was significantly lower in cages with occlusion of both inlet and outlet airflow. Weekly inspection revealed that occlusion of ventilation ports was detectable by 3 mo after semiannual sanitation. This study demonstrates that silicone nozzles should be removed prior to rack sanitation to improve the effectiveness of cleaning ventilation ports and nozzles. While the rack is in use, silicone nozzles and ventilation ports should be inspected regularly to identify occlusion that is likely to diminish environmental quality in the cage. Intracage ammonia levels are significantly higher when both inlet and outlet airflow are occluded.

    Full Text Available Following the recent expiry of the United Nations' 2015 Millennium Development Goals (MDGs, new international development agenda covering 2030 water, sanitation and hygiene (WASH targets have been proposed, which imply new demands on data sources for monitoring relevant progress. This study evaluates drinking-water and sanitation classification systems from national census questionnaire content, based upon the most recent international policy changes, to examine national population census's ability to capture drinking-water and sanitation availability, safety, accessibility, and sustainability. In total, 247 censuses from 83 low income and lower-middle income countries were assessed using a scoring system, intended to assess harmonised water supply and sanitation classification systems for each census relative to the typology needed to monitor the proposed post-2015 indicators of WASH targets. The results signal a lack of international harmonisation and standardisation in census categorisation systems, especially concerning safety, accessibility, and sustainability of services in current census content. This suggests further refinements and harmonisation of future census content may be necessary to reflect ambitions for post-2015 monitoring.

    Water and sanitation represents a key battlefront in combating the spread of antimicrobial resistance (AMR). Basic water sanitation infrastructure is an essential first step to protecting public health, thereby limiting the spread of pathogens and the need for antibiotics. AMR presents unique human health risks, meriting new risk assessment frameworks specifically adapted to water and sanitation-borne AMR. There are numerous exposure routes to AMR originating from human waste, each of which must be quantified for its relative risk to human health. Wastewater treatment plants (WWTPs) play a vital role in centralized collection and treatment of human sewage, but there are numerous unresolved questions in terms of the microbial ecological processes occurring within and the extent to which they attenuate or amplify AMR. Research is needed to advance understanding of the fate of resistant bacteria and antibiotic resistance genes (ARGs) in various waste management systems, depending on the local constraints and intended re-use applications. WHO and national AMR action plans would benefit from a more holistic 'One Water' understanding. Here we provide a framework for research, policy, practice, and public engagement aimed at limiting the spread of AMR from water and sanitation in both low-, medium- and high-income countries, alike.

  8. Perceptions of Health Communication, Water Treatment and Sanitation in Artibonite Department, Haiti, March-April 2012.

    Full Text Available The international response to Haiti's ongoing cholera outbreak has been multifaceted, including health education efforts by community health workers and the distribution of free water treatment products. Artibonite Department was the first region affected by the outbreak. Numerous organizations have been involved in cholera response efforts in Haiti with many focusing on efforts to improve water, sanitation, and hygiene (WASH. Multiple types of water treatment products have been distributed, creating the potential for confusion over correct dosage and water treatment methods. We utilized qualitative methods in Artibonite to determine the population's response to WASH messages, use and acceptability of water treatment products, and water treatment and sanitation knowledge, attitudes and practices at the household level. We conducted eighteen focus group discussions (FGDs: 17 FGDs were held with community members (nine among females, eight among males; one FGD was held with community health workers. Health messages related to WASH were well-retained, with reported improvements in hand-washing. Community health workers were identified as valued sources of health information. Most participants noted a paucity of water-treatment products. Sanitation, specifically the construction of latrines, was the most commonly identified need. Lack of funds was the primary reason given for not constructing a latrine. The construction and maintenance of potable water and sanitation services is needed to ensure a sustainable change.

    2015-04-01

    Container-based sanitation (CBS) - in which wastes are captured in sealable containers that are then transported to treatment facilities - is an alternative sanitation option in urban areas where on-site sanitation and sewerage are infeasible. This paper presents the results of a pilot household CBS service in Cap Haitien, Haiti. We quantify the excreta generated weekly in a dense urban slum, (1) the proportion safely removed via container-based public and household toilets, and the costs associated with these systems. The CBS service yielded an approximately 3.5-fold decrease in the unmanaged share of faeces produced, and nearly eliminated the reported use of open defecation and "flying toilets" among service recipients. The costs of this pilot small-scale service were higher than those of large-scale waterborne sewerage, but economies of scale have the potential to reduce CBS costs over time. The paper concludes with a discussion of planning and policy implications of incorporating CBS into the menu of sanitation options for rapidly growing cities.

From 2005 to 2009, the National Poison Data System received reports of 68,712 exposures to 96 ethanol-based hand sanitizers. The number of new cases increased by an average of 1,894 (95% confidence interval [CI] 1266-2521) cases per year (p =.002). In 2005, the rate of exposures, per year, per million U.S. residents was 33.7 (95% CI 28.4-39.1); from 2005 to 2009, this rate increased on average by 5.87 per year (95% CI 3.70-8.04; p = .003). In 2005, the rate of intentional exposures, per year, per million U.S. residents, was 0.68 (95% CI 0.17-1.20); from 2005 to 2009, this rate increased on average by 0.32 per year (95% CI 0.11-0.53; p = .02). The number of new cases per year of intentional hand sanitizer ingestion significantly increased during this 5-yr period. Although the majority of cases of hand sanitizer ingestion have a favorable outcome, 288 moderate and 12 major medical outcomes were reported in this National Poison Data System cohort. Increased awareness of the risks associated with intentional ingestion is warranted, particularly among healthcare providers caring for persons with a history of substance abuse, risk-taking behavior, or suicidal ideation.

    Abstract Objective By nature, chiropractic is a hands-on profession using manipulation applied to the joints with direct skin-to-skin contacts. Chiropractic tables are designed with a face piece to accommodate the prone patient's head in a neutral position and hand rests to allow for relaxed shoulders and upper spine so treatment is facilitated. The purpose of this article is to present a proposed guideline for hand and treatment table surface sanitizing for the chiropractic profession that is evidence-based and can easily be adopted by teaching institutions and doctors in the field. Methods A review of the chiropractic literature demonstrated that pathogenic microbes are present on treatment tables in teaching clinics at multiple facilities, yet no standardized protocols exist in the United States regarding table sanitizing and hand hygiene in chiropractic clinics or education institutions. This article reviews the scientific literature on the subject by using several search engines, databases, and specific reviews of documents pertaining to the topic including existing general guidelines. Results The literature has several existing guidelines that the authors used to develop a proposed protocol for hand and table sanitizing specific to the chiropractic profession. Recommendations were developed and are presented on hand hygiene and table sanitizing procedures that could lower the risk of infection for both clinical personnel and patients in chiropractic facilities. Conclusion This article offers a protocol for hand and table sanitizing in chiropractic clinics and education institutions. The chiropractic profession should consider adoption of these or similar measures and disseminate them to teaching clinics, institutions, and private practitioners. PMID:19646384

    We conducted an expert assessment to obtain expert opinions on the relative global resilience of ten drinking water and five sanitation technologies to the following six climate-related hazards: drought, decreased inter-annual precipitation, flood, superstorm flood, wind damage, and saline intrusion. Resilience scores ranged from 1.7 to 9.9 out of a maximum resilience of 10, with high scores corresponding to high resilience. We find that for some climate-related hazards, such as drought, technologies demonstrated a large range in resilience, indicating that the choice of water and sanitation technologies is important for areas prone to drought. On the other hand, the range of resilience scores for superstorm flooding was much smaller, particularly for sanitation technologies, suggesting that the choice of technology is less of a determinant of functionality for superstorm flooding as compared to other climate-related hazards. For drinking water technologies, only treated piped utility-managed systems that use surface water had resilience scores >6.0 for all hazards, while protected dug wells were found to be one of the least resilient technologies, consistently scoring <5.0 for all hazards except wind damage. In general, sanitation technologies were found to have low to medium resilience, suggesting that sanitation systems need to be adapted to ensure functionality during and after climate-related hazards. The results of the study can be used to help communities decide which technologies are best suited for the climate-related challenges they face and help in future adaptation planning.

    Water and sanitation indicators under the Millennium Development Goals failed to capture high-risk practices undertaken on a regular basis. In conjunction with local partners, fourteen rounds of household surveys using mobile phones with a customized open-source application were conducted across nine study geographies in Asia and Africa. In addition to the main water and sanitation facilities, interviewees (n = 245,054) identified all water and sanitation options regularly used for at least one season of the year. Unimproved water consumption and open defecation were targeted as high-risk practices. We defined underreporting as the difference between the regular and main use of high-risk practices. Our estimates of high-risk practices as the main option matched the widely accepted Demographic and Health Surveys (DHS) estimates within the 95% confidence interval. However, estimates of these practices as a regular option was far higher than the DHS estimates. Across the nine geographies, median underreporting of unimproved water use was 5.5%, with a range of 0.5% to 13.9%. Median underreporting of open defecation was much higher at 9.9%, with a range of 2.7% to 11.5%. This resulted in an underreported population of 25 million regularly consuming unimproved water and 50 million regularly practicing open defecation. Further examination of data from Ethiopia suggested that location and socio-economic factors were significant drivers of underreporting. Current global monitoring relies on a framework that considers the availability and use of a single option to meet drinking water and sanitation needs. Our analysis demonstrates the use of multiple options and widespread underreporting of high-risk practices. Policies based on current monitoring data, therefore, fail to consider the range of challenges and solutions to meeting water and sanitation needs, and result in an inflated sense of progress. Mobile surveys offer a cost-effective and innovative platform to rapidly

    Ensuring access to clean, safe sanitation for the world's population remains a challenging, yet critical, global sustainability goal. Ecological-based sanitation (EcoSan) technology is a promising strategy for improving sanitation, particularly in areas where financial resources and infrastructure are limiting. The composting of human waste and its use as an agricultural soil amendment can tackle three important challenges in developing countries - providing improved sanitation for vulnerable communities, reducing the spread of intestinal-born pathogens, and returning nutrients and organic matter to degraded agricultural soils. The extent of these benefits and potential tradeoffs are not well known, but have important implications for the widespread adoption of this strategy to promote healthy communities and enhance food security. We quantified the effects of EcoSan on the climate and human health in partnership with Sustainable Organic Integrated Livelihoods (SOIL) in Haiti. We measured greenhouse gas emissions (nitrous oxide, methane, and carbon dioxide) from compost piles that ranged in age from 0 to 14 months (i.e. finished) from two compost facilities managed with or without cement lining. We also measured emissions from a government-operated waste treatment pond and a grass field where waste has been illegally dumped. The highest methane emissions were observed from the anaerobic waste pond, whereas the dump site and compost piles had higher nitrous oxide emissions. Net greenhouse gases (CO2-equivalents) from unlined compost piles were 8x lower than lined compost piles and 20 and 30x lower than the dump and waste pond, respectively. We screened finished compost for fecal pathogens using bacterial 16S sequencing. Bacterial pathogens were eliminated regardless of the type of composting process. Pilot trials indicate that the application of compost to crops has a large potential for increasing food production. This research suggests that EcoSan systems are

    Only 79% of individuals living in rural Honduras use improved water sources. Inadequate drinking water quality is related to diarrheal illness, which in Honduras contributes to 18.6 episodes of diarrhea per child year in children under five years of age. The purpose of this study was to examine and compare access to drinking water and sanitation, as well as self-reported diarrheal disease incidence among three proximal communities in the Department of Yoro area of Honduras. An 11-item language-specific, interviewer-administered, anonymous questionnaire was administered to 263 randomly selected adults attending a June 2011 medical brigade held in the communities of Coyoles, La Hicaca, and Lomitas. Chi-square with Fisher exact tests were utilized to compare water access, sanitation, and self-reported diarrheal incidence among these communities. Coyoles and La Hicaca used private faucets as their primary water sources. Coyoles had the greatest use of bottled water. Lomitas used rivers as their primary water source, and did not use bottled water. Mostly, females were responsible for acquiring water. Usage of multiple water sanitation methods was most common in Coyoles, while no sanitation method was most common in Lomitas. In Lomitas and La Hicaca, water filters were mostly provided via donation by non-governmental organizations. Lomitas had the highest reported incidence of diarrhea among self and other household members. Critical differences in water access, sanitation, and self-reported diarrheal incidence among three geographically distinct, yet proximal, communities highlights the need for targeted interventions even in geographically proximal rural areas.

    The vacuum sanitation is the safe and sound disposal approach of human excreta under the specific environments like flights, high speed trains and submarines. However, the propulsive force of current systems is not adjustable and the energy consumption does not adapt to the real time sewerage requirement. Therefore, it is important to study the sewerage force adjustment to improve the energy efficiency. This paper proposes an energy conservation design in vacuum sanitation systems with pneumatic ejector circuits. The sewerage force is controlled by changing the systematic vacuum degree according to the amount of the excreta. In particular, the amount of the excreta is tested by liquid level sensor and mass sensor. According to the amount of the excreta, the relationship between the excreta amount and the sewerage force is studied to provide proper propulsive force. In the other aspect, to provide variable vacuum degrees for different sanitation requirements, the suction and discharge system is designed with pneumatic vacuum ejector. On the basis of the static flow-rate characteristics and the vacuum generation model, the pressure response in the ejector circuit is studied by using the static flow rate characteristics of the ejector and air status equation. The relationship is obtained between supplied compressed air and systematic vacuum degree. When the compressed air is supplied to the ejector continuously, the systematic vacuum degree increases until the vacuum degree reaches the extreme value. Therefore, the variable systematic vacuum degree is obtained by controlling the compressed air supply of the ejector. To verify the effect of energy conservation, experiments are carried out in the artificial excreta collection, and the variable vacuum-degree design saves more than 30% of the energy supply. The energy conservation is realized effectively in the new vacuum sanitation systems with good application prospect. The proposed technology provides technological

    Full Text Available Although the world has progressed in the area of water and sanitation, more than 2.3 billion people still live without access to sanitation facilities and some are unable to practice basic hygiene. Access to water and basic sanitation has deteriorated in Chitungwiza and children are at risk of developing illness and missing school due to the deterioration. We sought to investigate the predisposing, enabling and reinforcing factors that are causally related to water- and sanitation- related hygiene practices among school going children. A random sample of 400 primary school children (196 males, 204 females in four schools in Chitungwiza town, Zimbabwe was interviewed. Behavioural factors were assessed through cross examination of the PROCEED PRECEDE Model. The respondents had been stratified through the random sampling where strata were classes. A structured observation checklist was also administered to assess hygiene enabling facilities for each school. Children’s knowledge and perceptions were inconsistent with hygienic behaviour. The family institution seemed to play a more important role in life skills training and positive reinforcement compared to the school (50% vs 27.3%. There was no association between a child’s sex, age and parents’ occupation with any of the factors assessed (P=0.646. Schools did not provide a hygiene enabling environment as there were no learning materials, policy and resources on hygiene and health. The challenges lay in the provision of hygiene enabling facilities, particularly, the lack of access to sanitation for the maturing girl child and a school curriculum that provides positive reinforcement and practical life skills training approach.

    International monitoring of drinking water and sanitation has been jointly carried out by WHO and UNICEF through their Joint Monitoring Programme (JMP). With the end of the Millennium Development Goals (MDGs) era in 2015, the JMP has proposed a post-2015 framework for integrated monitoring of water and sanitation targets included in the Sustainable Development Goal no. 6. This article discusses how each element of the proposed sanitation target and corresponding indicators can be understood from a human rights perspective. Building on the MDGs, and although some of the weaknesses and gaps persist, the discussion suggests that the post-2015 proposal is a step forward towards a monitoring framework where human rights elements related to sanitation are effectively promoted. In addition, to support the interpretation and implementation of the normative content of human rights obligations related to sanitation, the study proposes a reduced set of easy-to-assess indicators to measure the normative criteria of this right, which are then grouped in a multidimensional framework to describe increasing levels of sanitation service. To do this, the study combines literature review and specific local experience from three case studies. It is shown that the proposed monitoring tools, namely the indicators and the multidimensional indicator framework, provide guidance on monitoring the human right to sanitation. In doing so, they might ultimately help sector stakeholders in the realization of this right. Copyright © 2016 Elsevier B.V. All rights reserved.

    Mills, Freya; Petterson, Susan; Norman, Guy

    2018-01-01

    Public health benefits are often a key political driver of urban sanitation investment in developing countries, however, pathogen flows are rarely taken systematically into account in sanitation investment choices. While several tools and approaches on sanitation and health risks have recently been developed, this research identified gaps in their ability to predict faecal pathogen flows, to relate exposure risks to the existing sanitation services, and to compare expected impacts of improvements. This paper outlines a conceptual approach that links faecal waste discharge patterns with potential pathogen exposure pathways to quantitatively compare urban sanitation improvement options. An illustrative application of the approach is presented, using a spreadsheet-based model to compare the relative effect on disability-adjusted life years of six sanitation improvement options for a hypothetical urban situation. The approach includes consideration of the persistence or removal of different pathogen classes in different environments; recognition of multiple interconnected sludge and effluent pathways, and of multiple potential sites for exposure; and use of quantitative microbial risk assessment to support prediction of relative health risks for each option. This research provides a step forward in applying current knowledge to better consider public health, alongside environmental and other objectives, in urban sanitation decision making. Further empirical research in specific locations is now required to refine the approach and address data gaps. PMID:29360775

    Current sanitation systems are inherently limited in their ability to address the new challenges for (waste)water management that arise from the rising demand to restore resource cycles. These challenges include removal of micropollutants, water (re)use, and nutrient recovery. New opportunities to address these challenges arise from new sanitation, a system innovation that combines elements of source separation, local treatment and reuse, and less use of water. New sanitation is applied, but not yet widespread, in several residential areas in Europe. Implementation is hindered by the lack of insight into the general public's willingness to engage in new sanitation, and the resulting uncertainty about this among decision makers and other stakeholders in wastewater management. Using value-belief-norm theory as a conceptual lens, this paper addresses the individual motivations (pro-environmental personal norms) and personal drivers (benefits) and barriers (risks) for acceptance of new sanitation by the Dutch general public. The results of an online survey (N = 338) indicated that both pro-environmental personal norms and risk and benefit perceptions predict consumers' willingness to accept new sanitation. More specifically, they showed that consumer acceptance is driven by perceived risks relating to the housing market and the need to change behavior, but also by environmental benefits. Overall, new sanitation was favorably evaluated by respondents: 64% indicated that they would likely use new sanitation if they were owner-occupiers. The results of this explorative study are discussed in light of the development of novel sanitation systems that are sensitive to perceptions of end-users and other key stakeholders.

    Disclosed is a fuel handling guide tube centering device for use in nuclear reactors during fuel assembly handling operations. The device comprises an outer ring secured to the flange of a nuclear reactor pressure vessel, a rotatable table rotatably coupled to the outer ring, and a plurality of openings through the table. Truncated locating cones are positioned in each of the openings in the table, and the locating cones center the guide tube during fuel handling operations. The openings in the table are located such that each fuel assembly in the nuclear core may be aligned with one of the openings by a suitable rotation of the table. The locating cones thereby provide alignment between the fuel handling mechanism located in the guide tube and the individual fuel assemblies of the cone. The need for a device to provide alignment is especially critical for floating nuclear power plants, where wave motion may exist during fuel handling operations. 5 claims, 4 figures

    Purpose: To prevent loss of cooling effect over the entire torus structure directly after accidental toubles in a cooling device of a thermonuclear device. Constitution: Coolant recycling means of a cooling device comprises two systems, which are alternately connected with in-flow pipeways and exit pipeways of adjacent modules. The modules are cooled by way of the in-flow pipeways and the exist pipeways connected to the respective modules by means of the coolant recycling means corresponding to the respective modules. So long as one of the coolant recycling means is kept operative, since every one other modules of the torus structure is still kept cooled, the heat generated from the module put therebetween, for which the coolant recycling is interrupted, is removed by means of heat conduction or radiation from the module for which the cooling is kept continued. No back-up emergency cooling system is required and it can provide high economic reliability. (Kamimura, M.)

    Full Text Available Hygiene during childbirth is essential to the health of mothers and newborns, irrespective of where birth takes place. This paper investigates the status of water and sanitation in both the home and facility childbirth environments, and for whom and where this is a more significant problem.We used three datasets: a global dataset, with information on the home environment from 58 countries, and two datasets for each of four countries in Eastern Africa: a healthcare facility dataset, and a dataset that incorporated information on facilities and the home environment to create a comprehensive description of birth environments in those countries. We constructed indices of improved water, and improved water and sanitation combined (WATSAN, for the home and healthcare facilities. The Joint Monitoring Program was used to construct indices for household; we tailored them to the facility context-household and facility indices include different components. We described what proportion of women delivered in an environment with improved WATSAN. For those women who delivered at home, we calculated what proportion had improved WATSAN by socio-economic status, education and rural-urban status.Among women delivering at home (58 countries, coverage of improved WATSAN by region varied from 9% to 53%. Fewer than 15% of women who delivered at home in Sub-Saharan Africa, had access to water and sanitation infrastructure (range 0.1% to 37%. This was worse among the poorest, the less educated and those living in rural areas. In Eastern Africa, where we looked at both the home and facility childbirth environment, a third of women delivered in an environment with improved water in Uganda and Rwanda; whereas, 18% of women in Kenya and 7% in Tanzania delivered with improved water and sanitation. Across the four countries, less than half of the facility deliveries had improved water, or improved water and sanitation in the childbirth environment.Access to water and

    Per United Nations' Sustainable Development Goals, Nepal is aspiring to achieve universal and equitable access to safe and affordable drinking water and provide access to adequate and equitable sanitation for all by 2030. For these goals to be accomplished, it is important to understand the country's geographical heterogeneity and inequality of access to its drinking-water supply and sanitation (WSS) so that resource allocation and disease control can be optimized. We aimed 1) to estimate spatial heterogeneity of access to improved WSS among the overall Nepalese population at a high resolution; 2) to explore inequality within and between relevant Nepalese administrative levels; and 3) to identify the specific administrative areas in greatest need of policy attention. We extracted cluster-sample data on the use of the water supply and sanitation that included 10,826 surveyed households from the 2011 Nepal Demographic and Health Survey, then used a Gaussian kernel density estimation with adaptive bandwidths to estimate the distribution of access to improved WSS conditions over a grid at 1 × 1 km. The Gini coefficient was calculated for the measurement of inequality in the distribution of improved WSS; the Theil L measure and Theil T index were applied to account for the decomposition of inequality. 57% of Nepalese had access to improved sanitation (range: 18.1% in Mahottari to 100% in Kathmandu) and 92% to drinking-water (range: 41.7% in Doti to 100% in Bara). The most unequal districts in Gini coefficient among improved sanitation were Saptari, Sindhuli, Banke, Bajura and Achham (range: 0.276 to 0.316); and Sankhuwasabha, Arghakhanchi, Gulmi, Bhojpur, Kathmandu (range: 0.110 to 0.137) among improved drinking-water. Both the Theil L and Theil T showed that within-province inequality was substantially greater than between-province inequality; while within-district inequality was less than between-district inequality. The inequality of several districts was

    This research project was dedicated to the model sanitation of the oil-contaminated subsoil of the filling station of a brewery shut down in 1987. The in situ sanitation equipment was operated from 1990 early in May to 1992 early in March. The techniques applied comprised drainage with automatic separation of the hydrocarbon phase, removal of air from the soil by suction for elimination of highly volatile components, in situ reaction of low-volatility components with ozone and removal of reaction products by suction, biodegradation of the residual pollutants. The sanitation was successful, and the safety system applied was found to have stood the test. Experiences were gained for more efficient and more rapid ozone-based soil sanitation in the future.

    Protrusions and recesses are formed to a vacuum vessel and toroidal magnetic coils, and they are engaged. Since the vacuum vessel is generally supported firmly by a rack or the like by support legs, the toroidal magnetic field coils can be certainly supported against tumbling force. Then, there can be attained strong supports for the toroidal magnetic field coils, in addition to support by wedges on the side of inboard and support by share panels on the side of outboard, capable of withstanding great electromagnetic forces which may occur in large-scaled next-generation devices. That is, toroidal magnetic field coils excellent from a view point of deformation and stress can be obtained, to provide a thermonuclear device of higher reliability. (N.H.)

This enables to bring the average irregular magnetic fields as a whole in the thermonuclear device nearly to zero, as well as, decrease the absolute value of the irregular magnetic fields in each positions. Thus, the plasma confining performances can be improved. (Moriyama, K.)

    Higher interclutch colour variation can evolve under the pressure of brood parasitism to increase the detection of parasitic eggs. Nest sanitation could be a prerequisite for the evolution of anti-parasite defence in terms of egg ejection. In this respect, we used nest sanitation behaviour as a tool to identify: i) motivation and its underlying function and, ii) which features provoke ejection behaviour. Therefore, we experimentally tested whether size, colour or shape may influence ejection ...

    Sanitation aims to sequester human feces and prevent exposure to fecal pathogens. More than 2.4 billion people worldwide lack access to improved sanitation facilities and almost one billion practice open defecation. We undertook systematic reviews and meta-analyses to compile the most recent evidence on the impact of sanitation on diarrhea, soil-transmitted helminth (STH) infections, trachoma, schistosomiasis, and nutritional status assessed using anthropometry. We updated previously published reviews by following their search strategy and eligibility criteria. We searched from the previous review's end date to December 31, 2015. We conducted meta-analyses to estimate pooled measures of effect using random-effects models and conducted subgroup analyses to assess impact of different levels of sanitation services and to explore sources of heterogeneity. We assessed risk of bias and quality of the evidence from intervention studies using the Liverpool Quality Appraisal Tool (LQAT) and Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach, respectively. A total of 171 studies met the review's inclusion criteria, including 64 studies not included in the previous reviews. Overall, the evidence suggests that sanitation is protective against diarrhea, active trachoma, some STH infections, schistosomiasis, and height-for-age, with no protective effect for other anthropometric outcomes. The evidence was generally of poor quality, heterogeneity was high, and GRADE scores ranged from very low to high. This review confirms positive impacts of sanitation on aspects of health. Evidence gaps remain and point to the need for research that rigorously describes sanitation implementation and type of sanitation interventions. Copyright © 2017 The Authors.

  4. The International Drinking Water Supply and Sanitation Decade in South-East Asia.

    Science.gov (United States)

    1984-01-01

    The International Drinking Water Supply and Sanitation Decade, 1981-90, which has a diversity of objectives, takes a different form in each country. What makes this decade different from previous actions for water and sanitation is the way in which the programs, projects, and servces are to be conceived, planned, implemented, managed, operated, and maintained. The urban population to be covered by water and sanitation services, in the developing nations that have prepared plans for the Decade, is roughly between 280-290 million people. In rural areas, some 750 million people are to be provided with drinking water and around 300 million with sanitation facilities. The initial goal of 100% of the population to be provided with water and sanitation by 1990 is proving difficult to realize. Only a small proportion of developing nations have even planned for 100% coverage by 1990. The initial optimism arising from the declaration of the Decade and the expectations of increased aid has given way to realism in the face of the global recession and the scarcity of development capital. The Southeast Asia Region of the World Health Organization (WHO) covers 11 member countries with a combined population of over 1000 million people. Among the countries in Southeast Asia that have prepared Decade plans, the following populations are to be covered by 1990: urban water supply, 126 million; urban sanitation, 156 million; rural water supply, 585 million; and rural sanitation, 212 million. Such a challenge calls for a stock taking of the real issues in order to identify what action can be taken. The lack of up-to-date and comprehensive databases is a serious problem. The information system for the Decade should be and integral part of it, be timed to keep pace with it, and be developed from the lowest level. The annual investment needed during the Decade is estimated at over 4 times that prior to the Decade. The accepted strategy is to meet the minimum needs of the largest number of

    Despite decreasing prevalence, rotavirus infections still rank among the most important viral infections in colonies of laboratory mice. Although the disease is characterized by low mortality and a relatively short and mild clinical period, the infection has the potential to alter the outcome of experiments substantially. For animal facilities, it is therefore essential to eradicate the virus. Here we report a successful sanitation of a rotavirus-infected mouse colony in an animal facility. Despite a high ratio of transgenic and partially immunodeficient strains, a permanent eradication of the virus was achieved by euthanasia of highly susceptible mice, a prolonged breeding cessation in areas containing immunocompromised mice and a strict hygienic management. The management of a rotavirus infection reported here is a feasible and inexpensive opportunity for sanitation that benefits from maintaining most of the animal population, even in today's mouse colonies comprising mainly transgenic mice with unknown or compromised immune status.

Bhojpuri is a dialect of Hindi spoken in parts of the north Indian states of Uttar Pradesh and Bihar. The influx of migrants from these regions to different parts of India has led to a resurgence of interest in the Bhojpuri media, and has drawn fly-by-night operators to the industry. To cater to the migrants’ needs, ribald action romances are produced; but this very bawdiness hamstrings attempts to widen the audience base. The article examines the issues that plague the industry, and explores the ways in which the industry is struggling to carve a sanitized, yet distinctive identity.

    African governments, like most countries in the developing world, face daunting tasks in their attempts to provide effective and equitable water and sanitation services for their ever increasing urban populations. Consequently, the past few years have witnessed increased private sector participation in urban water and sanitation provision, as many African governments strive to improve access to water and sanitation services for their citizens in line with Millennium Development Goal 7 (MDG7). Since the early 1990s, the government of Ghana and many local authorities have entered into various forms of public-private partnerships in urban water and sanitation provision. This article examines the outcome of such partnerships using the Tamale Metropolitan Area (TMA) as a case study with the aim of providing policy guidelines for the way forward. The article argues that the public-private arrangement for water supply and sanitation infrastructure management in the Tamale Metropolis has done nothing that an invigorated public sector could not have possibly achieved. It concludes that there can be no sustainable improvement in water and sanitation provision without political commitment, stakeholder ownership, and strong support for community driven initiatives.

    Using Health Impact Assessment methods, we determined: 1) the impact of water and sanitation infrastructure installed about 15 years ago in two Texas border communities; 2) the impact of failing septic tanks in a neighborhood where septic systems are more than 20 years old and failing; and 3) the impacts of hauled water as the main household water source in a colonia. We obtained a total of 147 household surveys related to water and sanitation in four communities. Households who had obtained water and sanitation infrastructure had less skin problems, neuropathy, gastrointestinal illness, and stomach infections compared to an earlier time when they relied on local domestic wells or hauled water and septic tanks. Hepatitis A incidence in El Paso County, TX dropped precipitously after the implementation of water and sanitation infrastructure. Hauling water contributed to mental stress and anxiety and was risky in terms of road safety. We also assessed the economic and community development impacts of water and sanitation infrastructure. Communities benefitted from higher property values, expanded health care services, more parks and recreation, more local businesses, and improved fire safety. We argue that though water and sanitation infrastructure is a significant contributor to addressing inequities in the border region, much remains to be done to achieve water justice in this challenging region.

    A large and growing proportion of the global population rely on shared sanitation facilities despite evidence of a potential increased risk of adverse health outcomes compared with individual household latrines (IHLs). We sought to explore differences between households relying on shared sanitation versus IHLs in terms of demographics, sanitation facilities, and fecal exposure. We surveyed 570 households from 30 slums in Orissa, India, to obtain data on demographics, water, sanitation, and hygiene. Latrine spot-checks were conducted to collect data on indicators of use, privacy, and cleanliness. We collected samples of drinking water and hand rinses to assess fecal contamination. Households relying on shared sanitation were poorer and less educated than those accessing IHLs. Individuals in sharing households were more likely to practice open defecation. Shared facilities were less likely to be functional, less clean, and more likely to have feces and flies. No differences in fecal contamination of drinking water or hand-rinse samples were found. Important differences exist among households accessing shared facilities versus IHLs that may partly explain the apparent adverse health outcomes associated with shared sanitation. As these factors may capture differences in risk and promote sanitary improvements, they should be considered in future policy. © The American Society of Tropical Medicine and Hygiene.

    Identifying the sanitation efficacy in reducing contaminations entering the environment is an important step for water pollution controls and developing management strategies to further improve sanitation conditions. With continuous efforts in sanitation improvement during the past decade, reductions in discharges of aquatic nutrients are expected in China. In this study, we estimated the aquatic nitrogen discharges from human excreta in 31 provinces in China during 2006-2014. The results indicated that the nitrogen discharges entering the environment from human excreta are largely determined by both local population and sanitation conditions. In 2014, the nitrogen discharges from human excreta in the rural areas (2118(1219-3140) Gg per year) (median and 95% confidence interval) are higher than those in the urban areas (1485(626-2495) Gg per year). The significant relationship (R 2 =0.38, n=29) between the total nitrogen concentrations in lakes and corresponding local nitrogen discharges indicated that, the lakes might be potentially affected by the contaminant inputs from human excreta. The further calculations under two policy scenarios showed that through sanitation improvement, further reduction of nitrogen discharges from human excreta in the developed regions might be limited. The sanitation improvement in the less-developed regions, such as Tibet, Qinghai, and Ningxia, should be considered a priority due to the larger reduction potentials. Copyright © 2017 Elsevier B.V.

  15. Centralised, decentralised or hybrid sanitation systems? Economic evaluation under urban development uncertainty and phased expansion.

    Sanitation systems are built to be robust, that is, they are dimensioned to cope with population growth and other variability that occurs throughout their lifetime. It was recently shown that building sanitation systems in phases is more cost effective than one robust design. This phasing can take place by building small autonomous decentralised units that operate closer to the actual demand. Research has shown that variability and uncertainty in urban development does affect the cost effectiveness of this approach. Previous studies do not, however, consider the entire sanitation system from collection to treatment. The aim of this study is to assess the economic performance of three sanitation systems with different scales and systems characteristics under a variety of urban development pathways. Three systems are studied: (I) a centralised conventional activated sludge treatment, (II) a community on site source separation grey water and black water treatment and (III) a hybrid with grey water treatment at neighbourhood scale and black water treatment off site. A modelling approach is taken that combines a simulation of greenfield urban growth, a model of the wastewater collection and treatment infrastructure design properties and a model that translates design parameters into discounted asset lifetime costs. Monte Carlo simulations are used to evaluate the economic performance under uncertain development trends. Results show that the conventional system outperforms both of the other systems when total discounted lifetime costs are assessed, because it benefits from economies of scale. However, when population growth is lower than expected, the source-separated system is more cost effective, because of reduced idle capacity. The hybrid system is not competitive under any circumstance due to the costly double piping and treatment. Copyright © 2016 Elsevier Ltd. All rights reserved.

    WHO and UNICEF have proposed an action plan to achieve universal water, sanitation and hygiene (WASH) coverage in healthcare facilities (HCFs) by 2030. The WASH targets and indicators for HCFs include: an improved water source on the premises accessible to all users, basic sanitation facilities, a hand washing facility with soap and water at all sanitation facilities and patient care areas. To establish viable targets for WASH in HCFs, investigation beyond 'access' is needed to address the state of WASH infrastructure and service provision. Patient and caregiver use of WASH services is largely unaddressed in previous studies despite being critical for infection control. The state of WASH services used by staff, patients and caregivers was assessed in 17 rural HCFs in Rwanda. Site selection was non-random and predicated upon piped water and power supply. Direct observation and semi-structured interviews assessed drinking water treatment, presence and condition of sanitation facilities, provision of soap and water, and WASH-related maintenance and record keeping. Samples were collected from water sources and treated drinking water containers and analyzed for total coliforms, E. coli, and chlorine residual. Drinking water treatment was reported at 15 of 17 sites. Three of 18 drinking water samples collected met the WHO guideline for free chlorine residual of >0.2 mg/l, 6 of 16 drinking water samples analyzed for total coliforms met the WHO guideline of hygienic condition and accessible to patients. Regular maintenance of WASH infrastructure consisted of cleaning; no HCF had on-site capacity for performing repairs. Quarterly evaluations of HCFs for Rwanda's Performance Based Financing system included WASH indicators. All HCFs met national policies for water access, but WHO guidelines for environmental standards including water quality were not fully satisfied. Access to WASH services at the HCFs differed between staff and patients and caregivers.

    This study was conducted to provide information regarding mitigation of cross-contamination through the use of sanitizer during crisping at retail outlets. Seven non-inoculated heads and one inoculated head (≈5 log CFU/g) of lettuce were placed into commercial sink filled with 76 L of tap water (TW), electrolyzed water (EW, free chlorine: 43 ± 6 ppm), lactic acid and phosphoric acid-based sanitizer (LPA, pH 2.89), or citric acid-based sanitizer (CA, pH 2.78) and soaked for 5 min. Two subsequent batches (eight non-inoculated heads per batch) were soaked in the same solution. Soaking with EW significantly reduced the population of S. enterica (2.8 ± 1.5 log CFU/g), E. coli O157:H7 (3.4 ± 1.1 log CFU/g), and L. monocytogenes (2.6 ± 0.7 log CFU/g) inoculated on Romaine lettuce compared to TW, LPA, and CA (p lettuce, EW significantly reduced populations of S. enterica and E. coli O157:H7, but not L. monocytogenes compared to other treatments. No significant difference was noted between TW, LPA, and CA in reducing foodborne pathogens (p > 0.05) or preventing cross-contamination. Soaking with EW prevented cross-contamination among lettuce heads and controlled bacterial populations in crisping water for three consecutive batches. EW may be an effective option as a sanitizer to minimizing the cross-contamination of leafy greens during the retail crisping. Copyright © 2017 Elsevier Ltd. All rights reserved.

  19. Analysis of behavioral change techniques in community-led total sanitation programs.

    2015-03-01

    The lack of sanitation facilitates the spread of diarrheal diseases-a leading cause of child deaths worldwide. As of 2012, an estimated 1 billion people still practiced open defecation (OD). To address this issue, one behavioral change approach used is community-led total sanitation (CLTS). It is now applied in an estimated 66 countries worldwide, and many countries have adopted this approach as their main strategy for scaling up rural sanitation coverage. While it appears that many of the activities used in CLTS-that target community-level changes in sanitation behaviors instead of household-level changes-have evolved out of existing behavior change frameworks and techniques, it is less clear how these activities are adapted by different organizations and applied in different country contexts. The aims of this study are to (i) show which behavior change frameworks and techniques are the most common in CLTS interventions; (ii) describe how activities are implemented in CLTS interventions by region and context; and (3) determine which activities program implementers considered the most valuable in achieving open defecation free (ODF) status and sustaining it. The results indicate that a wide range of activities are conducted across the different programs and often go beyond standard CLTS activities. CLTS practitioners ranked follow-up and monitoring activities as the most important activities for achieving an ODF community, yet only 1 of 10 organizations conducted monitoring and follow-up throughout their project. Empirical studies are needed to determine which specific behavioral change activities are most effective at ending OD and sustaining it. © The Author 2014. Published by Oxford University Press.
