    Historically, pollution prevention activities within the Department of Energy (DOE) have focused on existing process waste streams. However, the DOE estimates that 70 percent of the opportunity to reduce or eliminate pollutants is gained or lost during design. Design is considered a critical component of the DOE`s operations, products and services, as evidenced by the numerous new facilities planned to support the cleanup mission of the complex. Pollution prevention during design: (a) significantly reduces the potential generation of waste and environmental releases, (b) promotes the use of energy efficient materials, (c) minimizes resource consumption, and (d) lowers life-cycle costs. Life-cycle cost considerations during design can include construction, operation, and eventual decommissioning of the facility. This paper highlights: (1) the development of the guideline, including specific examples of the guideline`s content and intended use, (2) a discussion on the philosophy and content of the training module, (3) a strategy for integrating the guideline`s use into the existing DOE design process, and (4) future plans for enhancing the guideline and training class while continuing to integrate pollution prevention into the DOE design process.

    1999-07-01

    Air Force Plant 44 in Tucson, Arizona is owned by the Air Force and operated by Raytheon Missile Systems Company. A joint Air Force/Raytheon Pollution Prevention Team operates at AFP 44 with the ultimate goal to minimize or eliminate the use of hazardous substances. The team works together to uncover new technologies and methods that will replace chemicals used in the plant's missile manufacturing facilities. The program maximizes pollution prevention by first eliminating hazardous material use, then chemical recycling, next hazardous waste reduction and finally wastewater treatment and recycling. From fiscal years 1994 through 1997, nine pollution prevention projects have been implemented, totaling $2.6 million, with a payback averaging less than two years. A unique wastewater treatment method has been demonstrated as part of this program. This is electroflotation, a Russian technology which removes dispersed particles from liquid with gas bubbles obtained during water electrolysis. A unit was built in the US which successfully removed organic emulsions from wastewater. Operational units are planned for the removal of waste from waterfall paint booths. The pollution prevention joint team continues to be very active with two projects underway in FY 98 and two more funded for FY 99.

    Between 1991 and 2012, the facilities that reported to the U.S. Environmental Protection Agency's Toxic Release Inventory (TRI) Program conducted 370,000 source reduction projects. We use this data set to conduct the first quasi-experimental retrospective evaluation of how implementing a source reduction (pollution prevention) project affects the quantity of toxic chemicals released to the environment by an average industrial facility. We use a differences-in-differences methodology, which measures how implementing a source reduction project affects a facility's releases of targeted chemicals, relative to releases of (a) other untargeted chemicals from the same facility, or (b) the same chemical from other facilities in the same industry. We find that the average source reduction project causes a 9-16% decrease in releases of targeted chemicals in the year of implementation. Source reduction techniques vary in effectiveness: for example, raw material modification causes a large decrease in releases, while inventory control has no detectable effect. Our analysis suggests that in aggregate, the source reduction projects carried out in the U.S. since 1991 have prevented between 5 and 14 billion pounds of toxic releases.

    Prosperity without pollution, and the consideration of how to achieve this economic and environmental imperative, has become the fundamental environmental theme of the 1990s. The new strategy--pollution prevention--will serve s the keystone of federal, state, and local environmental policy. The challenge is to switch from two decades of environmental policy based on pollution controls and government-mandated regulations to a future environmental policy based on pollution prevention, source reduction, recycling, and waste minimization. To make this change will require a new social compact among environmental, industrial, and regulatory interests. This chapter focuses on the role of chemistry and the contributions of synthetic and process analytical chemists. It also describes the implementation of pollution prevention concepts into the premanufacturing notice review process mandated by Section 5 of the Toxic Substances Control Act (TSCA) and discusses the implications of pollution prevention for chemical safety. 55 refs.

    1995-09-01

    General Motors facilities are engaged in numerous pollution prevention activities and projects. GM has instituted pollution prevention, recyclability, and other manufacturing considerations into the design process of the vehicle. This approach is effective in reducing the total life-cycle impact of GM vehicles. For the purposes of this handbook, two broad-based initiatives that have applications outside of the automotive industry will be discussed. First, chemicals management is a new supplier relationship that reduces the overall chemical cost while providing incentives for the chemical supplier to find ways to reduce chemical usage. The second initiative, packaging reduction and recycling, has been a great success at many of GM`s facilities. The goal is to reduce the amount of packaging coming into a plant and to make sure that the packaging that is received is easily recycled or returned.

  20. Pollution Prevention Program: Technology summary

    Energy Technology Data Exchange (ETDEWEB)

    1994-02-01

    The Department of Energy (DOE) has established a national Research, Development, Demonstration, Testing, and Evaluation (RDDT&E) Program for pollution prevention and waste minimization at its production plants During FY89/90 the Office of Environmental Restoration and Waste Management (EM), through the Office of Technology Development (OTD), established comprehensive, pollution prevention technical support programs to demonstrate new, environmentally-conscious technology for production processes. The RDDT&E program now entails collaborative efforts across DOE. The Pollution Prevention Program is currently supporting three major activities: The DOE/US Air Force Memorandum of Understanding Program is a collaborative effort to utilize the combined resources of DOE and the Department of Defense, eliminate duplication of effort in developing technologies, and to facilitate technology solutions aimed at reducing waste through process modification, material substitution or recycling. The Waste Component Recycle, Treatment and Disposal Integrated Demonstration (WeDID) will develop recycle, treatment, and disposal processes and associated technologies for use in the dismantlement of non-nuclear weapons components, to support US arms treaties and policies. This program will focus on meeting all security and regulatory requirements (with additional benefit to the commercial electronics industry). The Environmentally Conscious Manufacturing Integrated Demonstration (ECMID) will effectively implement ECM technologies that address both the needs of the DOE Complex and US electronics industry, and encourage strong interaction between DOE and US industry. The ECMID will also develop life cycle analysis tools that will aid decisionmakers in selecting the optimum process based on the tradeoffs between cost an environmental impact.

    1994-01-01

    In support of the US Department of Energy`s (DOE`s) pollution prevention efforts being conducted under the aegis of DOE`s Office of Environmental Restoration and Waste Management (EM) program, Pacific Northwest Laboratory was tasked with evaluating pollution prevention information resources. The goal of this activity was to improve the effectiveness of DOE`s pollution prevention activities through improved information flow, both within the complex, and more specifically, between DOE and other organizations that share similar pollution prevention challenges. This report presents our findings with respect to the role of information collection and dissemination within the complex, opportunities for teaming from successes of the private sector, and specific information needs of the DOE pollution prevention community. These findings were derived from a series of interviews with pollution prevention coordinators from across the DOE complex, review of DOE site and facility pollution prevention plans, and workshops with DOE information users as well as an information resources workshop that brought together information specialists from private industry, non-profit organizations, as well as state and regional pollution prevention assistance programs.

    2007-03-01

    It is the policy of the Department of Energy (DOE) that pollution prevention and sustainable environmental stewardship will be integrated into DOE operations as a good business practice to reduce environmental hazards, protect environmental resources, avoid pollution control costs, and improve operational efficiency and mission sustainability. In furtherance of this policy, DOE established five strategic, performance-based Pollution Prevention (P2) and Sustainable Environmental Stewardship goals and included them as an attachment to DOE O 450.1, Environmental Protection Program. These goals and accompanying strategies are to be implemented by DOE sites through the integration of Pollution Prevention into each site's Environmental Management System (EMS). This document presents a P2 and Sustainability Program and corresponding plan pursuant to DOE Order 450.1 and DOE O 435.1, Radioactive Waste Management. This plan is also required by the state of Idaho, pursuant to the Resource Conservation and Recovery Act (RCRA) partial permit. The objective of this document is to describe the Idaho National Laboratory (INL) Site P2 and Sustainability Program. The purpose of the program is to decrease the environmental footprint of the INL Site while providing enhanced support of its mission. The success of the program is dependent on financial and management support. The signatures on the previous page indicate INL, ICP, and AMWTP Contractor management support and dedication to the program. P2 requirements have been integrated into working procedures to ensure an effective EMS as part of an Integrated Safety Management System (ISMS). This plan focuses on programmatic functions which include environmentally preferable procurement, sustainable design, P2 and Sustainability awareness, waste generation and reduction, source reduction and recycling, energy management, and pollution prevention opportunity assessments. The INL Site P2 and Sustainability Program is administratively

  3. Pollution Prevention Wipe Application Study

    Energy Technology Data Exchange (ETDEWEB)

    Lopez, E.P.; Modderman, W.E.; Montoya, M.G.

    1999-02-10

    As part of a pollution prevention program, a study was conducted at Sandia National Laboratories and at the Amarillo, ''Pantex Plant'' to identify a suitable replacement solvent(s) for cleaning hardware during routine maintenance operations. Current cleaning is performed using solvents (e.g. acetone, toluene, MEK, alcohols) that are classified as Resource Conservation and Recovery Act (RCW) materials. The Environmental Protection Agency (EPA) has assigned four characteristics as the criteria for determining whether a material is identified as hazardous under RCRA: Ignitability, Corrosivity, Reactivity and Toxicity. Within the DOE and DoD sector, these solvents are used with hand wipes to clean surfaces prior to O-ring replacement, to remove decals for new labeling, to clean painted surfaces prior to reconditioning, and for other general maintenance purposes. In some cases, low level radioactive contamination during cleaning necessitates that the RCIL4 solvent-containing wipes be classified as mixed waste. To avoid using RCRA materials, cleaning candidates were sought that had a flashpoint greater than 140 F, a pH between 2.5 and 12.5, and did not fail the reactivity and toxicity criteria. Three brominated cleaners, two hydrofluoroether azeotropes and two aliphatic hydrocarbon cleaner formulations were studied as potential replacements. Cleaning efficacy, materials compatibility, corrosion and accelerated aging studies were conducted and used to screen potential candidates. Hypersolve NPB (an n-propyl bromide based formulation) consistently ranked high in removing typical contaminants for weapons applications.

    This project investigated technologies that may reduce environmental pollution. This was a basic research/educational project addressing two major areas: A. In the algae research project, newly isolated strains of microalgae were investigated for feedstock production to address the production of renewable fuels. An existing collection of microalgae was screened for lipid composition to determine strains with superior composition of biofuel molecules. As many microalgae store triacylglycerides in so-called oil bodies, selected candidate strains identified from the first screen that accumulate oil bodies were selected for further biochemical analysis, because almost nothing was known about the biochemistry of these oil bodies. Understanding sequestration of triacylglycerides in intracellular storage compartments is essential to developing better strains for achieving high oil productivities by microalgae. At the onset of the project there was almost no information available on how to obtain detailed profiles of lipids from strains of microalgae. Our research developed analytical methods to determine the lipid profiles of novel microalgal strains. The project was embedded into other ongoing microalgal projects in the Polle laboratory. The project benefited the public, because students were trained in cell cultivation and in the operation of state-of-the-art analytical equipment. In addition, students at Brooklyn College were introduced into the concept of a systems biology approach to study algal biofuels production. B. A series of new nanostructured catalysts were synthesized, and characterized by a variety of physical and chemical methods. Our catalyst design leads to active nanostructures comprising small metal particles in intimate contact with strongly basic sites provided by the supports, which include poly(4-vinylpyridine), magnesium oxide, functionalized multi-walled carbon nanotubes, and graphene oxide. The new materials display a good potential as catalysts

  6. D&D TECHNOLOGIES FOR POLLUTION PREVENTION

    Energy Technology Data Exchange (ETDEWEB)

    Tripp, Julia L.

    2003-02-27

    A new Accelerated Site Technology Deployment (ASTD) project was awarded in FY 2002 to the Idaho National Engineering and Environmental Laboratory (INEEL) to deploy technologies that decrease pollution and waste in the areas of facility characterization, sludge treatment, dust and contamination control, and concrete demolition. This project was called ''D&D Technologies for Pollution Prevention'' and planned to deploy four different technologies. To reduce protective equipment requirements, waste generation, and risk of radiation exposure during facility characterization, the Russian Gamma Locater Device (GLD) and Isotopic Identification Device (IID) for remote characterization was investigated. The GLD detects gamma ray readings and video images remotely and uses radio communication to transmit the readings to personnel located a safe distance from the contaminated area. The IID, an integral part of the GLD, provides real-time spectrometric analysis of radiation sources for remotely identifying the specific radioactive isotopes present in the facility. At the INEEL, sludge has accumulated in the bottom of a fuel storage pool and the presence of heavy metals in the sludge makes it a mixed waste. This project planned to use LEADX{reg_sign} to treat sludge in place to effectively make all heavy metals in the sludge insoluble. LEADX{reg_sign} is a dry granular chemical additive (apatite) used for in-situ treatment of heavy-metal-contaminated material. LEADX{reg_sign} chemically bonds to any free heavy metals that it contacts and forms a stable, non-leachable molecule. After treating the sludge with LEADX{reg_sign}, it was to be left in the basin and the pool filled with grout. The successful treatment of the sludge with LEADX{reg_sign} will reduce the amount of waste to be disposed at the burial ground by eliminating the need to remove the sludge from the basin. Many off-gas and duct systems being dismantled contain dust and lint that has been

    1995-12-01

    Pollution prevention is at the top of the waste management hierarchy in the United States. If you don`t create pollution in the first place, concerns about transportation, treatment, storage, and disposal of waste are moot. While industry is on the front line in accomplishing significant pollution prevention, universities can play a meaningful role in its accomplishment as well. Universities can do this through three basic missions: education, research, and public service. Examples of how this is carried out at the University of Tennessee, Knoxville are provided. To be fully effective, universities need to organize in an interdisciplinary manner and adopt a public outreach agenda.

    The US Department of Energy`s (DOE`s) Pollution Prevention Information Clearinghouse (EPIC) is a computer system intended for the exchange of pollution prevention information DOE-wide. EPIC is being developed as a distributed system that will allow access to other databases and applications. The first prototype of EPIC (Prototype I) was put on-line in January 1994. Prototype I contains information on EM-funded pollution prevention projects; relevant laws, regulations, guidance, and policy; facility and DOE contacts; and meetings and conferences. Prototype I also gives users access to the INEL Hazardous Solvent Substitution Data System (HSSDS) and to information contained on the US Environmental Protection Agency`s (EPNS) Pollution Prevention Infbrmation Exchange System (PIES) as a test of the distributed system concept. An initial user group of about 35 is testing and providing feedback on Prototype I. Prototype II, with a Graphical User Interface (GUI), is planned for the end of CY94. This paper describes the current state of EPIC in terms of architecture, user interface, and information content. Plans for Prototype II and the final system are then discussed. The EPIC development effort is being coordinated with EPA and US Department of Defense (DoD) efforts to develop or upgrade their pollution prevention information exchange systems.

  14. Good Practice Guide Waste Minimization/Pollution Prevention

    Energy Technology Data Exchange (ETDEWEB)

    J Dorsey

    1999-10-14

    This Good Practice Guide provides tools, information, and examples for promoting the implementation of pollution prevention during the design phases of U.S. Department of Energy (DOE) projects. It is one of several Guides for implementing DOE Order 430.1, Life-cycle Asset Management. DOE Order 430.1 provides requirements for DOE, in partnership with its contractors, to plan, acquire, operate, maintain, and dispose of physical assets. The goals of designing for pollution prevention are to minimize raw material consumption, energy consumption, waste generation, health and safety impacts, and ecological degradation over the entire life of the facility (EPA 1993a). Users of this Guide will learn to translate national policy and regulatory requirements for pollution prevention into action at the project level. The Guide was written to be applicable to all DOE projects, regardless of project size or design phase. Users are expected to interpret the Guide for their individual project's circumstances, applying a graded approach so that the effort is consistent with the anticipated waste generation and resource consumption of the physical asset. This Guide employs a combination of pollution prevention opportunity assessment (PPOA) methods and design for environment (DfE) philosophies. The PPOA process was primarily developed for existing products, processes, and facilities. The PPOA process has been modified in this Guide to address the circumstances of the DOE design process as delineated in DOE Order 430.1 and its associated Good Practice Guides. This modified form of the PPOA is termed the Pollution Prevention Design Assessment (P2DA). Information on current nationwide methods and successes in designing for the environment also have been reviewed and are integrated into this guidance.

  17. Pollution prevention opportunity assessment benchmarking: Recommendations for Hanford

    Energy Technology Data Exchange (ETDEWEB)

    Engel, J.A.

    1994-05-01

    Pollution Prevention Opportunity Assessments (P2OAs) are an important first step in any pollution prevention program. While P2OAs have been and are being conducted at Hanford, there exists no standard guidance, training, tracking, or systematic approach to identifying and addressing the most important waste streams. The purpose of this paper then is to serve as a guide to the Pollution Prevention group at Westinghouse Hanford in developing and implementing P2OAs at Hanford. By searching the literature and benchmarks other sites and agencies, the best elements from those programs can be incorporated and pitfalls more easily avoided. This search began with the 1988 document that introduces P2OAs (then called Process Waste Assessments, PWAS) by the Environmental Protection Agency. This important document presented the basic framework of P20A features which appeared in almost all later programs. Major Department of Energy programs were also examined, with particular attention to the Defense Programs P20A method of a graded approach, as presented at the Kansas City Plant. The graded approach is a system of conducting P2OAs of varying levels of detail depending on the size and importance of the waste stream. Finally, private industry programs were examined briefly. While all the benchmarked programs had excellent features, it was determined that the size and mission of Hanford precluded lifting any one program for use. Thus, a series of recommendations were made, based on the literature review, in order to begin an extensive program of P2OAs at Hanford. These recommendations are in the areas of: facility Pollution Prevention teams, P20A scope and methodology, guidance documents, training for facilities (and management), technical and informational support, tracking and measuring success, and incentives.

  18. Safety installation for preventing pollution by pipelines

    Energy Technology Data Exchange (ETDEWEB)

    Wittgenstein, G.F.

    1972-10-25

    A safety installation for preventing pollution by pipelines, particularly those used for transporting liquid hydrocarbons, is described. It is applicable to any pipeline, but particularly to underground or submarine pipelines, whether made of steel, plastics, or any other material. The 4 essential objects of the invention are to insure reliable prevention of pollution of the environment due to leakage of a hydrocarbon through cracks in the pipe; to evacuate the leakage flow without delay to a vessel; to signal almost instantaneously the existence of a leak; and to effect remote control of operations by which the dynamic pressure in the pipe is cancelled. Each equipped section consists of a fluid-type jacket of plastic material which surrounds the pipe, which at its ends is sealed off. It is these seals which delimit the sections. (7 claims)

    The pollution prevention program operated by the Health Department of Boulder County is called Business Partners for a Clean Environment (Business Partners). It is a cooperative effort among local businesses, the City of Boulder, Boulder County, and the Boulder Chamber of Commerce. This nonregulatory, incentive-based program provides industry with pollution prevention information and technical assistance necessary to reduce and/or eliminate environmental waste. This paper provides an overview of the program development, creation of partnerships and trust, and some of the results from implementation of the program. Following the first 18 months of the program, 35 businesses were recognized as Business Partners. The Business Partners program has also received an achievement award from the National Association of Counties for promoting {open_quotes}responsible, responsive, and effective government{close_quotes} and two governor`s awards from the State of Colorado. Participating businesses have demonstrated that a pollution prevention program can reduce environmental waste, increase employee safety, and decrease costs. 4 refs., 4 figs., 5 tabs.

  1. Optimization of preventive health care facility locations

    2010-03-01

    Full Text Available Abstract Background Preventive health care programs can save lives and contribute to a better quality of life by diagnosing serious medical conditions early. The Preventive Health Care Facility Location (PHCFL problem is to identify optimal locations for preventive health care facilities so as to maximize participation. When identifying locations for preventive health care facilities, we need to consider the characteristics of the preventive health care services. First, people should have more flexibility to select service locations. Second, each preventive health care facility needs to have a minimum number of clients in order to retain accreditation. Results This paper presents a new methodology for solving the PHCFL problem. In order to capture the characteristics of preventive health care services, we define a new accessibility measurement that combines the two-step floating catchment area method, distance factor, and the Huff-based competitive model. We assume that the accessibility of preventive health care services is a major determinant for participation in the service. Based on the new accessibility measurement, the PHCFL problem is formalized as a bi-objective model based on efficiency and coverage. The bi-objective model is solved using the Interchange algorithm. In order to accelerate the solving process, we implement the Interchange algorithm by building two new data structures, which captures the spatial structure of the PHCFL problem. In addition, in order to measure the spatial barrier between clients and preventive health care facilities accurately and dynamically, this paper estimates travelling distance and travelling time by calling the Google Maps Application Programming Interface (API. Conclusions Experiments based on a real application for the Alberta breast cancer screening program show that our work can increase the accessibility of breast cancer screening services in the province.

    1996-09-01

    This Report summarizes the waste generation and pollution prevention activities of the major operational sites in the Department of Energy (DOE). We are witnessing progress in waste reduction from routine operations that are the focus of Department-wide reduction goals set by the Secretary on May 3,1996. The goals require that by the end of 1999, we reduce, recycle, reuse, and otherwise avoid waste generation to achieve a 50 percent reduction over 1993 levels. This Report provides the first measure of our progress in waste reduction and recycling against our 1993 waste generation baseline. While we see progress in reducing waste from our normal operations, we must begin to focus attention on waste generated by cleanup and facilities stabilization activities that are the major functions of the Office of Environmental Management. Reducing the generation of waste is one of the seven principles that I have established for the Office of Environmental Management Ten Year Plan. As part of our vision to complete a major portion of the environmental cleanup at DOE sites over the next ten years, we must utilize the potential of the pollution prevention program to reduce the cost of our cleanup program. We have included the Secretarial goals as part of the performance measures for the Ten Year Plan, and we are committed to implementing pollution prevention ideas. Through the efforts of both Federal and contractor employees, our pollution prevention program has reduced waste and the cost of our operations. I applaud their efforts and look forward to reporting further waste reduction progress in the next annual update of this Report.

    Industrialization in developing countries is causing increasing environmental damage. Pollution prevention (P2) is an emerging environmental concept that could help developing countries achieve leapfrog goals, bypassing old and pollutive technologies and minimizing traditional control practices. The current P2 promotion activities in Hong Kong, the Republic of Korea, the Philippines, Singapore, Taiwan, and Thailand are discussed. These programs, generally initiated in the last 5 years, are classified into five categories: awareness promotion, education and training, information transfer, technical assistance, and financial incentives. All important at the early stages of P2 promotion, these programs should inform industries of the benefits of P2 and help them identify applicable P2 measures. Participation in these programs is voluntary. The limited data indicate that adoption of P2 measures in these countries is not yet widespread. Recommendations for expanding P2 promotion activities include (1) strengthening the design and enforcement of environmental regulations; (2) providing P2 training and education to government workers, nongovernmental organizations and labor unions officials, university faculties, and news media; (3) tracking the progress of P2 programs; (4) implementing selected P2 mandatory measures; (5) identifying cleaner production technologies for use in new facilities; (6) implementing special programs for small and medium enterprises; and (7) expanding P2 promotion to other sectors, such as agriculture and transportation, and encouraging green design and green consumerism.

    The purpose of the Pollution Prevention Awareness Program (PPAP), which is required by DOE Order 5400.1, is to foster the philosophy that prevention is superior to remediation. The goal of the program is to incorporate pollution prevention into the decision-making process at every level throughout the organization. The objectives are to instill awareness, disseminate information, provide training and rewards for identifying the true source or cause of wastes, and encourage employee participation in solving environmental issues and preventing pollution. PPAP at the Oak Ridge Y-12 Plant was created several years ago and continues to grow. We believe that we have implemented several unique methods of communicating environmental awareness to promote a more active work force in identifying ways of reducing pollution.

    Meltzer, M.

    1993-12-01

    Today`s industrial processes generate many types of waste products that constitute risks to human health and the surrounding environment. While proper waste management procedures can lower this risk, prevention of the waste`s generation will eliminate the risk. For this reason, the United States has established pollution prevention as a national objective, through the passage of its Pollution Prevention Act of 1990. Pollution prevention involves a wide range of approaches, all with the same objective: to reduce or eliminate the creation of waste at its source in other words, within the process that generates it. This objective, so beneficial to the environment, also coincides with industrial economic interests. Pollution prevention measures and greater process efficiency go hand in hand, and typically result in lower operating costs as well as greatly reduced waste management expenses. The US Environmental Protection Agency defines pollution prevention as the maximum feasible reduction of all wastes generated at production sites. This objective is accomplished largely through source reduction and reuse of input materials during production.

    The purpose of this presentation is to relay the experience of the Office of New Production Reactors (NP) in developing and implementing its pollution prevention program. NP was established to plan, design, and construct a new safe and environmentally acceptable nuclear reactor capacity necessary to provide an assured supply of tritium to maintain the nation`s long-term deterrent capability. The Program offered the Department of Energy an opportunity to demonstrate its commitment to environmental protection via minimization of environmental releases; new design offers the best opportunity for pollution prevention. The NP pollution prevention program was never fully implemented because NP`s tritium production design activity was recovery terminated. The information in this paper represented lessons learned from the last three years of NP operation.

  8. Web-based expert system for foundry pollution prevention

    Science.gov (United States)

    Moynihan, Gary P.

    2004-02-01

    Pollution prevention is a complex task. Many small foundries lack the in-house expertise to perform these tasks. Expert systems are a type of computer information system that incorporates artificial intelligence. As noted in the literature, they provide a means of automating specialized expertise. This approach may be further leveraged by implementing the expert system on the internet (or world-wide web). This will allow distribution of the expertise to a variety of geographically-dispersed foundries. The purpose of this research is to develop a prototype web-based expert system to support pollution prevention for the foundry industry. The prototype system identifies potential emissions for a specified process, and also provides recommendations for the prevention of these contaminants. The system is viewed as an initial step toward assisting the foundry industry in better meeting government pollution regulations, as well as improving operating efficiencies within these companies.

    Styles, David; O'Brien, Kieran; Jones, Michael B

    2009-11-01

    This paper presents an innovative, quantitative assessment of pollution avoidance attributable to environmental regulation enforced through integrated licensing, using Ireland's pharmaceutical-manufacturing sector as a case study. Emissions data reported by pharmaceutical installations were aggregated into a pollution trend using an Environmental Emissions Index (EEI) based on Lifecycle Assessment methodologies. Complete sectoral emissions data from 2001 to 2007 were extrapolated back to 1995, based on available data. Production volume data were used to derive a sectoral production index, and determine 'no-improvement' emission trends, whilst questionnaire responses from 20 industry representatives were used to quantify the contribution of integrated licensing to emission avoidance relative to these trends. Between 2001 and 2007, there was a 40% absolute reduction in direct pollution from 27 core installations, and 45% pollution avoidance relative to hypothetical 'no-improvement' pollution. It was estimated that environmental regulation avoided 20% of 'no-improvement' pollution, in addition to 25% avoidance under business-as-usual. For specific emissions, avoidance ranged from 14% and 30 kt a(-1) for CO(2) to 88% and 598 t a(-1) for SO(x). Between 1995 and 2007, there was a 59% absolute reduction in direct pollution, and 76% pollution avoidance. Pollution avoidance was dominated by reductions in emissions of VOCs, SO(x) and NO(x) to air, and emissions of heavy metals to water. Pollution avoidance of 35% was attributed to integrated licensing, ranging from between 8% and 2.9 t a(-1) for phosphorus emissions to water to 49% and 3143 t a(-1) for SO(x) emissions to air. Environmental regulation enforced through integrated licensing has been the major driver of substantial pollution avoidance achieved by Ireland's pharmaceutical sector - through emission limit values associated with Best Available Techniques, emissions monitoring and reporting requirements, and

    Energy Technology Data Exchange (ETDEWEB)

    BRIGGS,S.L.K.; MUSOLINO,S.V.

    2001-06-01

    In early 1997 Brookhaven National Laboratory (BNL) discovered that the spent fuel pool of their High Flux Beam Reactor was leaking tritium into the groundwater. Community members, activist groups, politicians and regulators were outraged with the poor environmental management practices at BNL. The reactor was shut down and the Department of Energy (DOE) terminated the contract with the existing Management Company. At this same time, a major new scientific facility, the Relativistic Heavy Ion Collider (RHIC), was nearing the end of construction and readying for commissioning. Although environmental considerations had been incorporated into the design of the facility; some interested parties were skeptical that this new facility would not cause significant environmental impacts. RHIC management recognized that the future of its operation was dependent on preventing pollution and allaying concerns of its stakeholders. Although never done at a DOE National Laboratory before Brookhaven Science Associates, the new management firm, committed to implementing an Environmental Management System (EMS) and RHIC managers volunteered to deploy it within their facility on an extremely aggressive schedule. Several of these IS0 requirements contribute directly to preventing pollution, an area where particular emphasis was placed. This paper describes how Brookhaven used the following key IS0 14001 elements to institutionalize Pollution Prevention concepts: Environmental Policy, Aspects, Objectives and Targets, Environmental Management Program, Structure and Responsibility, Operational Controls, Training, and Management Review. In addition, examples of implementation at the RHIC Project illustrate how BNL's premiere facility was able to demonstrate to interested parties that care had been taken to implement technological and administrative controls to minimize environmental impacts, while at the same time reduce the applicability of regulatory requirements to their operations.

However, studies of the health risks from exposure to harmful substances often do not consider their toxicological characteristics. We used two different methods, the unit-hazard and the distance-based approach, to evaluate demographic and socio-economic characteristics of the population residing near industrial facilities in the City of Toronto, Canada. In addition to the mass of air emissions obtained from the national pollutant release inventory (NPRI, we also considered their toxicity using toxic equivalency potential (TEP scores. Results from the unit-hazard approach indicate no significant difference in the proportion of low-income individuals living in host versus non-host census tracts (t(107 = 0.3, P = 0.735. However, using the distance-based approach, the proportion of low-income individuals was significantly higher (+5.1%, t(522 = 6.0, P <0.001 in host tracts, while the indicator for “racialized” communities (“visible minority” was 16.1% greater (t(521 = 7.2, P <0.001 within 2 km of a NPRI facility. When the most toxic facilities by non-carcinogenic TEP score were selected, the rate of visible minorities living near the most toxic NPRI facilities was significantly higher (+12.9%, t(352 = 3.5, P = 0.001 than near all other NPRI facilities. TEP scores were also used to identify areas in Toronto that face a double burden of poverty and air toxics exposure in order to prioritise pollution prevention.

    The Environmental Protection Agency (EPA) published the final storm water regulation on November 16, 1990. The storm water regulation is included in the National Pollutant Discharge Elimination System (NPDES) regulations. An NPDES permit was issued for the Y-12 Plant on April 28, 1995, and was effective on July 1, 1995. The permit requires that a Storm Water Pollution Prevention Plan (SWP3) be developed by December 28, 1995, and be fully implemented by July 1, 1996; this plan has been developed to fulfill that requirement. The outfalls and monitoring points described in this plan contain storm water discharges associated with industrial activities as defined in the NPDES regulations. For storm water discharges associated with industrial activity, including storm water discharges associated with construction activity, that are not specifically monitored or limited in this permit, Y-12 Plant personnel will meet conditions of the General Storm Water Rule 1200-4-10. This document presents the programs and physical controls that are in place to achieve the following objectives: ensure compliance with Section 1200-4-10-.04(5) of the TDEC Water Quality Control Regulations and Part 4 of the Y-12 Plant NPDES Permit (TN0002968); provide operating personnel with guidance relevant to storm water pollution prevention and control requirements for their facility and/or project; and prevent or reduce pollutant discharge to the environment, in accordance with the Clean Water Act (CWA) and the Tennessee Water Quality Control Act.

    1995-12-31

    Total Quality Management (TQM) is a systematic philosophy of continually improving the way an organization accomplishes its goals in order to achieve superior bottom line results. Traditionally, environmental compliance has been viewed as an {open_quotes}add-on{close_quotes} to whatever business a company was engaged in. In contrast, achieving pollution prevention is a natural outcome of working within a TQM framework. This paper examines the application of TQM principles for three examples during the engineering phase of Reformulated Gasoline projects. The methodology used by the team and examples of the results achieved are presented. A case study of a wastewater compliance project that directly contrasts a traditional end-of-pipe approach with a TQM pollution prevention program is also presented.

    Full Text Available This article examines several aspects related to Romanian citizens' dispositions to financially contribute to the prevention of pollution. The data used are provided by the European Values Survey (EVS 1999 and the EVS/Public Opinion Barometer (BOP 2005. Both EVS waves used three specific questions, which investigated the extent to which persons would be willing to: 1. give up a part of their income, 2. accept a tax increase if this could contribute to the prevention of pollution, and 3. claim that the issue of pollution should be solved by the government, without individual financial contributions. These are the dependent variables of the analysis. Based on the epistemology of environmental citizenship literature, the dependent variables were dichotomized: the first two sentences are a semantic cover for the disposition towards active involvement, and the last sentence corresponds to the disposition towards passivity. In relation to these dependent variables, the effect of several independent variables (social-cultural, axiological, political-ideological, etc. was analyzed and, in the end, two different citizenship profiles, specific to the two dispositions studied, were outlined.

    Full Text Available Discharge of untreated waste waters into surface waters creates significant pollution in these resources. Wastewaters are most of the time discharged into seas, rivers and other water bodies without any treatments due to high treatment costs both in Turkey and throughout the world. Constructed wetlands, also called as natural treatment systems, are used as an alternative treatment system to conventional high-cost treatment systems because of their low construction, operation and maintenance costs, energy demands, easy operation and low sludge generation. Today, constructed wetland systems are largely used to treat domestic wastewaters, agricultural wastewaters, industrial wastewater and runoff waters and ultimately to prevent water pollution and to improve water quality of receiving water bodies. In present study, currently implemented practices in design, construction, operation and maintenance of constructed wetlands were assessed and potential mistakes made in different phases these systems were pointed out and possible solutions were proposed to overcome these problems.

    During President Carlos Salinas de Gortari`s administration, the environmental protection and pollution prevention programs throughout the country received an unprecedented financial and political support. The administration included from the beginning very aggressive action plans to protect and enhance the environment. To ensure that all these programs were going to be followed, the president instructed the National Commission of Ecology to include these programs within the National Development Plan, under the National Program for Protection of the Environment. The National Development Plan is a constitutional mandate that requires every Federal Government Action Plan to be designed in accordance with it. New national policies were implemented to enforce environmental legislation. Ten new programs to protect endangered species were approved by Congress, 44 national parks were declared under special federal protection, 14 biosphere reserves were established and 9 more were included to protect wildlife. The three largest cities in the country, Mexico City, Monterrey and Guadalajara received special attention in order to design and implement a program to promptly respond to air pollution emergencies. To control and reduce water pollution from mismanagement of untreated sewage in urban areas, financial support was allocated to build and operate water treatment plants.

However, studies of the health risks from exposure to harmful substances often do not consider their toxicological characteristics. We used two different methods, the unit-hazard and the distance-based approach, to evaluate demographic and socio-economic characteristics of the population residing near industrial facilities in the City of Toronto, Canada. In addition to the mass of air emissions obtained from the national pollutant release inventory (NPRI), we also considered their toxicity using toxic equivalency potential (TEP) scores. Results from the unit-hazard approach indicate no significant difference in the proportion of low-income individuals living in host versus non-host census tracts (t(107) = 0.3, P = 0.735). However, using the distance-based approach, the proportion of low-income individuals was significantly higher (+5.1%, t(522) = 6.0, P air toxics exposure in order to prioritise pollution prevention.

    The built environment supports the safe care of patients in health care facilities. Infection preventionists and health care epidemiologists have expertise in prevention and control of health care-associated infections (HAIs) and assist with designing and constructing facilities to prevent HAIs. However, design elements are often missing from initial concepts. In addition, there is a large body of evidence that implicates construction and renovation as being associated with clusters of HAIs, many of which are life threatening for select patient populations. This article summarizes known risks and prevention strategies within a framework for patient safety.

    This seventh Annual Report presents and analyzes DOE Complex-wide waste generation and pollution prevention activities at 45 reporting sites from 1993 through 1998. This section summarizes Calendar Year 1998 Complex-wide waste generation and pollution prevention accomplishments. More detailed information follows this section in the body of the Report. In May 1996, the Secretary of Energy established a 50 percent Complex-Wide Waste Reduction Goal (relative to the 1993 baseline) for routine operations radioactive, mixed, and hazardous waste generation, to be achieved by December31, 1999. DOE has achieved its Complex-Wide Waste Reduction Goals for routine operations based upon a comparison of 1998 waste generation to the 1993 baseline. Excluding sanitary waste, routine operations waste generation decreased 67 percent overall from 1993 to 1998. However, for the first time since 1994, the total amount of materials recycled by the Complex decreased from 109,600 metric tons in 1997 to 92,800 metric tons in 1998. This decrease is attributed to the fact that in 1997, several large ''one-time only'' recycling projects were conducted throughout the Complex. In order to demonstrate commitment to DOE's Complex-wide recycling goal, it is important for sites to identify all potential large-scale recycling/reuse opportunities.

    With the change in US Department of Energy`s (DOE) primary mission from weapons production to complex clean-up, there is an increased emphasis to utilize proven tools and techniques that, when modified, will assist in this massive remediation effort. Tools and techniques which increase process efficiency while minimizing costs are highly attractive. The introduction of formalized Pollution Prevention (P2) practices into the DOE Environmental Restoration (ER) program should be encouraged to the measurable degree of success that P2 has obtained in DOE process operations. Most notably, the integration of Pollution Prevention Opportunity Assessments (PPOAs) into the ER process is highly recommended for three reasons: waste stream generation volumes will be minimized; the results of P2 implementation will be properly measured, quantified, and documented for use on other projects; and negative impacts to human health and the environment will be lessened. the application of P2 principles is encouraged as a Best Management Practice (BMP), in addition to minimizing waste generation to achieve DOE waste reduction goals. The challenge is how to apply P2 practices to ER projects and obtain quantifiable waster reductions.

    Full Text Available The global push towards sustainability has led to increased interest in alternative power sources other than coal and fossil fuels. One of these sustainable sources is to harness energy from the wind through wind turbines. However, a significant hindrance preventing the widespread use of wind turbines is the noise they produce. This study reviews recent advances in the area of noise pollution from wind turbines. To date, there have been many different noise control studies. While there are many different sources of noise, the main one is aerodynamic noise. The largest contributor to aerodynamic noise comes from the trailing edge of wind turbine blades. The aim of this paper is to critically analyse and compare the different methods currently being implemented and investigated to reduce noise production from wind turbines, with a focus on the noise generated from the trailing edge.

  1. Pollution and Prevention of Pb during Cement Calcination

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Emission pollution and prevention measures of Pb during cement calcination were discussed. The content of Pb and the variation of composition were explored by means of atomic absorption spectroscopy (AAS) and X-ray diffraction. The results show that a number of Pb emits during cement calcination, F and C1 promote the emission of Pb, and Pb is enriched in kiln dust. The smaller the particle of kiln dust, the higher the content of Pb. When utilizing the raw materials with a high content of Pb, a more efficient dust collector should be used and the kiln dust should be used as the addition of cement. Pb in clinker is enriched in the intermediate phase. The reduction of silica modulus is useful to increase the solidification content of Pb in clinker. The solidification content of Pb in calcium sulphoaluminate mineral is higher than that in calcium aluminate mineral.

    This European Environment Agency (EEA) report assesses the damage costs to health and the environment resulting from pollutants emitted from industrial facilities. It is based on the latest information, namely for 2009, publicly available through the European Pollutant Release and Transfer Register (E-PRTR, 2011) in line with the United Nations Economic Commission for Europe (UNECE) Aarhus Convention regarding access to environmental information. This report investigates the use of a simplified modelling approach to quantify, in monetary terms, the damage costs caused by emissions of air pollutants from industrial facilities reported to the E-PRTR pollutant register. The approach is based on existing policy tools and methods, such as those developed under the EU's CAFE programme for the main air pollutants. This study also employs other existing models and approaches used to inform policymakers about the damage costs of pollutants. Together, the methods are used to estimate the impacts and associated economic damage caused by a number of pollutants emitted from industrial facilities, including: (1) ammonia (NH{sub 3}), nitrogen oxides (NO{sub x}), non-methane volatile organic compounds (NMVOCs), particulate matter (PM{sub 10}) and sulphur oxides (SO{sub x}); (2) heavy metals; (3) benzene, dioxins and furans, and polycyclic aromatic hydrocarbons (PAHs); (4) carbon dioxide (CO{sub 2}). The cost of damage caused by emissions from the E-PRTR industrial facilities in 2009 is estimated as being at least EUR 102-169 billion. A small number of industrial facilities cause the majority of the damage costs to health and the environment. Fifty per cent of the total damage cost occurs as a result of emissions from just 191 (or 2 %) of the approximately 10 000 facilities that reported at least some data for releases to air in 2009. Three quarters of the total damage costs are caused by the emissions of 622 facilities, which comprise 6 % of the total number. Of the

    In 1996 a survey of pollution prevention, environmental control, and occupational health and safety practices was conducted in the Rhode Island automotive refinishing industry sector. In conjunction with project partners, the Rhode Island Department of Environmental Management developed a multidimensional survey instrument to identify risk reduction opportunities. Investigators sought to characterize the range of environmental and industrial hygiene control employed by Rhode Island facilities for the purposes of focusing state technical and compliance assistance efforts. Data were collected on a diverse range of subject areas including work force demographics; source reduction; potential health hazards; worker protection and safety; solid and hazardous waste management; and air pollution control. Nearly one-half of the shops employ three or fewer people, and in many cases, spray painters double as body repair technicians thereby increasing their potential exposure to workplace contaminants. While nearly all of the shops reported that they use spray painting booths, only 38% own booths the more effective downdraft design. Based on the self-reported data, recently promulgated state air pollution control regulations (requiring the use of compliant coatings, enclosed or modified spray gun cleaners, and high-volume, low-pressure, spray guns) appear to be effective at motivating companies toward source reduction. A range of risk reduction opportunities were identified as input material changes, technology changes, and improved operating practices. Better methods of risk communication; a professional licensing requirement; and targeted training, compliance, and technical assistance would help to achieve greater levels of risk reduction in this mature, high-hazard industry.

    The design of non-point sources control facilities in Korea is divided largely by the stormwater capture ratio, the stormwater load capture ratio, and the pollutant reduction efficiency of the facility. The stormwater capture ratio is given by a design formula as a function of the water quality treatment capacity, the greater the capacity, the more the amount of stormwater intercepted by the facility. The stormwater load capture ratio is defined as the ratio of the load entering the facility of the total pollutant load generated in the target catchment, and is given as a design formula represented by a function of the stormwater capture ratio. In order to estimate the stormwater capture ratio and load capture ratio, a lot of quantitative analysis of hydrologic processes acted in pollutant emission is required, but these formulas have been applied without any verification. Since systematic monitoring programs were insufficient, verification of these formulas was fundamentally impossible. However, recently the Korean ministry of Environment has conducted an long-term systematic monitoring project, and thus the verification of the formulas became possible. In this presentation, the stormwater capture ratio and load capture ratio are re-estimated using actual TP data obtained from long-term monitoring program at Noksan industrial complex located in Busan, Korea. Through the re-estimated process, the uncertainty included in the design process that has been applied until now will be shown in a quantitative extent. In addition, each uncertainty included in the stormwater capture ratio estimation and in the stormwater load capture ratio estimation will be expressed to quantify the relative impact on the overall non-point pollutant control facilities design process. Finally, the SWMM-Matlab interlocking module for model parameters estimation will be introduced.

    1998-09-01

    This sixth Annual Report presents and analyzes DOE Complex-wide waste generation and pollution prevention activities at 36 reporting sites from 1993 through 1997. In May 1996, the Secretary of Energy established a 50 percent Complex-Wide Waste Reduction Goal (relative to the 1993 baseline) for routine operations radioactive and hazardous waste generation, to be achieved by December 31, 1999. Excluding sanitary waste, routine operations waste generation increased three percent from 1996 to 1997, and decreased 61 percent overall from 1993 to 1997. DOE has achieved its Complex-Wide Waste Reduction Goals for routine operations based upon a comparison of 1997 waste generation to the 1993 baseline. However, it is important to note that increases in low-level radioactive and low-level mixed waste generation could reverse this achievement. From 1996 to 1997, low-level radioactive waste generation increased 10 percent, and low-level mixed waste generation increased slightly. It is critical that DOE sites continue to reduce routine operations waste generation for all waste types, to ensure that DOE`s Complex-Wide Waste Reduction Goals are achieved by December 31, 1999.

  13. Oil and Gas Production Wastewater: Soil Contamination and Pollution Prevention

    2016-01-01

    Full Text Available During oil and natural gas production, so-called “produced water” comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic fracturing (HF fluids into the formation. Both produced water and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public health and the environment. Oil and gas production wastewater may serve a range of beneficial purposes, particularly in arid regions, if managed correctly. Numerous treatment technologies have been developed that allow for injection, discharge to the land surface, or beneficial reuse. Although many papers have addressed the effects of oil and gas production wastewater (OGPW on groundwater and surface water quality, significantly less information is available on the effects of these fluids on the soil resource. This review paper compiles fundamental information on numerous chemicals used and produced during oil and gas development and their effects on the soil environment. Additionally, pollution prevention technologies relating to OGPW are presented. An understanding of the effects of OGPW on soil chemical, physical, and biological properties can provide a foundation for effective remediation of OGPW-affected soils; additionally, sustainable reuse of oil and gas water for irrigation and industrial purposes may be enhanced.

    Pemberton, S.

    1996-02-01

    The Department of Energy and its contractors are faced with environmental concerns and large waste management costs. Federal legislation and DOE Orders require sites to develop waste minimization/pollution prevention programs. In response to these requirements, the Kansas City Plant developed a pollution prevention tool called a pollution prevention opportunity assessment (PPOA). Pilot assessments resulted in the development of a graded approach to reduce the amount of effort required for activities that utilized nonhazardous and/or low-volume waste streams. The project`s objectives in FY95 were to validate DOE`s PPOA Graded Approach methodology, provide PPOA training and technical assistance to interested DOE personnel and DOE contractors, enhance the methodology with energy analysis and tools for environmental restoration activities, implement a DOE-wide PPOA database, and provide support to DOE EM-334 in the completion of a report which estimates the future potential for pollution prevention and waste minimization in the DOE complex.

    This report shows the benefits small businesses can realize by instituting cost-effective pollution prevention improvements. It is a series of pollution prevention assessments that were conducted at small businesses in Richland, Washington. It describes a technology transfer test of US Department of Energy (USDOE) pollution prevention methods to small businesses through eleven pollution prevention assessments conducted at small businesses in the city of Richland. The assessment method tested was first developed at the USDOE Hanford Site, located in Richland, Washington. Two pilot studies were initially conducted to determine the usefulness of the assessment method for small businesses. Then, four additional pollution prevention assessments were conducted using a refined process. In order to determine the assessment method`s usefulness by different practitioners, a number of the assessments contained in this report were conducted by the undergraduate and graduate students at Washington State University at Tri-Cities as part of their class projects. These students were trained in the pollution prevention assessment process by the author of this report and conducted five small business assessments using the same methods and materials as in the remainder of the study.

    The health care program in working facilities and companies have played a significant part in prevention of tuberculosis. However, the ordinary national tuberculosis survey policy was abolished in April, 2005 and the tuberculosis survey for salary-earners is on the brink of drastic change. In this symposium the current status of the prevailing survey of tuberculosis in working facilities and companies was reviewed and the future direction of the tuberculosis survey in comparison to that in lung cancer survey was discussed. 1. Epidemiological trends of tuberculosis from the tuberculosis surveillance data: Masako OHMORI (Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association). The estimated rate of tuberculosis case discovery by periodical mass screening in the working facilities was 0.033% and it was higher than that in general adult population. The detection rate of tuberculosis in nurses who suffered from tuberculosis reached 40.4% by an aid of mass X-ray screening and 8.7% by contact tracing. The risk of onset of the disease was 4.3 times higher nurses than in general at the same years of age. The importance of infection control measures in the medical facilities was emphasized. 2. Current status and problems in tuberculosis control in a large-sized company: Yusuke NAKAOKA (Department of Occupational Health, Osaka Railway Hospital, West Japan Railway Company). Some preventive modalities against TB such as periodical medical check-up and awareness programs have been done for the purpose of prevention in our company. The prevalence of the disease has significantly reduced in number. The specific circumstances in large-sized company should be taken into consideration, and it is important for company workers and health professionals to recognize their roles in preventing the infectious disease. 3. Are there any differences between clinical cases and control people working for small-sized companies in the onset of tuberculosis?: Osamu NAKASHIMA, Kohei

    The source of ground water supply in Dawu is an extremely huge one in Shandong province. Now it is faced with serious pollution of petroleum in Hougao area. Aiming at this problem, the petroleum pollution in aeration zone and in groundwater was analyzed. The result shows that the contaminant of groundwater comes from the leaching of petroleum in the soil horizon of aeration zone through precipitation, and the quick flow of groundwater makes the convection dominate themigration of contaminant. So movement of groundwater controls the distribution of petroleum contaminant, which is consistent with the direction of ground flow. Building a groundwater closure zone in Hougao is an effective method to stop the contaminated groundwater flowing toward the water supply source of Dawu. The petroleum contaminant can be effectively reduced through using the aeration, biological and oxidation technologies.

    Mercury pollution in the Three Gorges Reservoir area of P. R. China merits special attention. We investigated into the current situation in the Chongqing part of the Reservoir area, identified the pollution sources and proposed some suggestions for the remediation and prevention of mercury pollution in this area. Atmospheric mercury in Chongqing was mainly from coal burning and releases of mercury-containing products such as various types of lights and fever thermometers. Urban drainage in Chongqing and Changshou, and runoffs from the high mercury background area in the lower reaches of the Wujiang River contributed most of the mercury in the water of the Yangtze River. A majority of the blame should be laid on mercury and gold mining in the Wujiang valley. We suggested foresting sloping lands to relieve soil erosion and prevent mercury-bearing soil from running into rivers, educational activities to discourage use of mercury-containing products and improved infrastructure to collect mercury-containing wastes for reducing mercury releases, more facilities for treating wastewater and solid waste to accommodate increased requirements of discharge, and growing selected perennial plants in mercury-contaminated land to absorb the mercury in soil. We also suggested concerted operation of a dedicated water-quality monitoring system, reinforced legislation and an effective administrative mechanism to ensure lasting efforts are invested in curbing mercury releases and restoring mercury contaminated land and water in the Reservoir area.

    Full Text Available Petroleum pollution is known as point and non-point source of contaminations in the environment. A major class of petroleum contaminant is groups of compounds consist of two or more fused benzene rings called polycyclic aromatic hydrocarbons (PAHs that are carcinogenic, mutagenic and toxic. Source identification of petroleum pollution is necessary to prevent pollution entry into the environment. Eight sedimentary cores were obtained from developed and developing areas around Peninsular Malaysia to investigate the historical profile of PAHs, their characteristics and its possible origins. The results showed that the PAHs concentrations varied from very minimum to 2400 ng/g d. w. in average quarter century intervals. Most of the studied locations showed high contribution of PAHs from combusted fuel, coal, biomasses and wood materials except for the southern part of Peninsular Malaysia in which revealed dominance of petroleum products. The findings indicate that PAHs are delivered from different intermediate materials such as asphalt, street dust, vehicular emission and crankcase oil. However, there has been a decline of PAHs input into the marine environment in recent years; petroleum is shown to be a significant cause of marine pollution since the second quarter of 20th century. An overview on sourced materials of petroleum pollution indicates multi-approach necessity toward pollution control, regardless of concentration and possible degradation processes. Various sectors both governmental and non-governmental are needed for prevention and control of petroleum pollution where different sources apparently contribute to the pollution generation process.

    Full Text Available Traffic on rivers and lakes in Europe has been ve1y well developed.The reason for this is the transport cost, relative speedand good connectivity of major European cities by rivers andcanals. In Croatia, this transport mode is lagging behind therest of Europe. Croatia is located at an interesting section of theriver transversal, but due to several reasons, river navigation inCroatia has not been developed to any major extent. As operatingriver ships the most frequent types are: towboats, pushboatsand self-propelled ships. The installed diesel engines, propulsionand auxiliary engines run at high power. Proportional tothe increase in the power of installed engines is also the increasein the volume of waste produced by the engines. Also, the olderthe engine, the greater volume of waste it produces. Ships mayalso cause pollution by wastewaters and garbage. This pollutionthreat grows with the greater number of people on boardand the age of the ship. In order to minimize these possibilitiesof pollution, it is necesswy to control all the time the properfunctioning of the ships, train the staff and construct receptionfacilities on land.

    A high flame temperature oxy-combustion test facility consisting of a 5 MWe equivalent test boiler facility and 20 KWe equivalent IPR® was constructed at the Hammond, Indiana manufacturing site. The test facility was operated natural gas and coal fuels and parametric studies were performed to determine the optimal performance conditions and generated the necessary technical data required to demonstrate the technologies are viable for technical and economic scale-up. Flame temperatures between 4930-6120F were achieved with high flame temperature oxy-natural gas combustion depending on whether additional recirculated flue gases are added to balance the heat transfer. For high flame temperature oxy-coal combustion, flame temperatures in excess of 4500F were achieved and demonstrated to be consistent with computational fluid dynamic modeling of the burner system. The project demonstrated feasibility and effectiveness of the Jupiter Oxygen high flame temperature oxy-combustion process with Integrated Pollutant Removal process for CCS and CCUS. With these technologies total parasitic power requirements for both oxygen production and carbon capture currently are in the range of 20% of the gross power output. The Jupiter Oxygen high flame temperature oxy-combustion process has been demonstrated at a Technology Readiness Level of 6 and is ready for commencement of a demonstration project.

    This paper presents a system for determining the evaluation and gradation indices of groundwater pollution intensity (GPI). Considering the characteristics of the vadose zone and pollution sources, the system decides which anti-seepage measures should be implemented at the contaminated site. The pollution sources hazards (PSH) and groundwater intrinsic vulnerability (GIV) are graded by the revised Nemerow Pollution Index and an improved DRTAS model, respectively. GPI is evaluated and graded by a double-sided multi-factor coupling model, which is constructed by the matrix method. The contaminated sites are categorized as prior, ordinary, or common sites. From the GPI results, we develop guiding principles for preventing and removing pollution sources, procedural interruption and remediation, and end treatment and monitoring. Thus, we can select appropriate prevention and control technologies (PCT). To screen the technological schemes and optimize the traditional analytical hierarchy process (AHP), we adopt the technique for order preference by the similarity to ideal solution (TOPSIS) method. Our GPI approach and PCT screening are applied to three types of pollution sites: the refuse dump of a rare earth mine development project (a potential pollution source), a chromium slag dump, and a landfill (existing pollution sources). These three sites are identified as ordinary, prior, and ordinary sites, respectively. The anti-seepage materials at the refuse dump should perform as effectively as a 1.5-m-thick clay bed. The chromium slag dump should be preferentially treated by soil flushing and in situ chemical remediation. The landfill should be treated by natural attenuation technology. The proposed PCT screening approach was compared with conventional screening methods results at the three sites and proved feasible and effective. The proposed method can provide technical support for the monitoring and management of groundwater pollution in China. - Highlights: • An

    Highlights: ► Effects of closing MSW facilities on perception of odour and pollution studied. ► Residents’ perception of odour nuisance considerably diminished post closure. ► Odour perception showed an association with distance from MSW facilities. ► Media coverage increased knowledge about MSW facilities and how they operate. ► Economic compensation possibly affected residents’ views and concerns. - Abstract: If residents’ perceptions, concerns and attitudes towards waste management facilities are either not well understood or underestimated, people can produce strong opposition that may include protest demonstrations and violent conflicts such as those experienced in the Campania Region of Italy. The aim of this study was to verify the effects of the closure of solid waste treatment and disposal facilities (two landfills and one RDF production plant) on public perception of odour and environmental pollution. The study took place in four villages in Southern Italy. Identical questionnaires were administered to residents during 2003 and after the closure of the facilities occurred in 2008. The residents’ perception of odour nuisance considerably diminished between 2003 and 2009 for the nearest villages, with odour perception showing an association with distance from the facilities. Post closure, residents had difficulty in identifying the type of smell due to the decrease in odour level. During both surveys, older residents reported most concern about the potentially adverse health impacts of long-term exposure to odours from MSW facilities. However, although awareness of MSW facilities and concern about potentially adverse health impacts varied according to the characteristics of residents in 2003, substantial media coverage produced an equalisation effect and increased knowledge about the type of facilities and how they operated. It is possible that residents of the village nearest to the facilities reported lower awareness of and concern about

    In the field of nuclear forensics, one of the biggest challenges is to dissolve postdetonation debris for analysis. Debris generated after a nuclear detonation is a glassy material that is difficult to dissolve with chemicals. Traditionally, concentrated nitric acid, hydrofluoric acid, or sulfuric acid are employed during the dissolution. These acids, due to their corrosive nature, are not suitable for in-field/on-site sample preparations. Uranium oxides are commonly present in nuclear fuel processing plants and nuclear research facilities. In uranium oxides, the level of uranium isotope enrichment is a sensitive indicator for nuclear nonproliferation and is monitored closely by the International Atomic Energy Agency (IAEA) to ensure there is no misuse of nuclear material or technology for nuclear weapons. During an IAEA on-site inspection at a facility, environmental surface swipe samples are collected and transported to the IAEA headquarters or network of analytical laboratories for further processing. Uranium oxide particles collected on the swipe medium are typically dissolved with inorganic acids and are then analyzed for uranium isotopic compositions. To improve the responsiveness of on-site inspections, in-field detection techniques have been recently explored. However, in-field analysis is bottlenecked by time-consuming and hazardous dissolution procedures, as corrosive inorganic acids must be used. Corrosive chemicals are difficult to use in the field due to personnel safety considerations, and the transportation of such chemicals is highly regulated. It was therefore necessary to develop fast uranium oxide dissolution methods using less hazardous chemicals in support of the rapid infield detection of anomalies in declared nuclear processes.

    The herbicides chloridazon and metribuzin, identified as groundwater pollutants, were incorporated in alginate-based granules to obtain controlled release properties. In this research the effect of incorporation of sorbents such as bentonite, anthracite and activated carbon in alginate basic formulation were not only studied on encapsulation efficiency but also on the release rate of herbicides which was studied using water release kinetic tests. In addition, sorption studies of herbicides with bentonite, anthracite and activated carbon were made. The kinetic experiments of chloridazon and metribuzin release in water have shown that the release rate is higher in metribuzin systems than in those prepared with chloridazon, which has lower water solubility. Besides, it can be deduced that the use of sorbents reduces the release rate of the chloridazon and metribuzin in comparison to the technical product and to the alginate formulation without sorbents. The highest decrease in release rate corresponds to the formulations prepared with activated carbon as a sorbent. The water uptake, permeability, and time taken for 50% of the active ingredient to be released into water, were calculated to compare the formulations. On the basis of a parameter of an empirical equation used to fit the herbicide release data, the release of chloridazon and metribuzin from the various formulations into water is controlled by a diffusion mechanism.

Sorption capacity of the sorbents for chloridazon and metribuzin, ranging from 0.53mgkg(-1) for the metribuzin sorption on bentonite to 2.03x10(5)mgkg(-1) for the sorption of chloridazon on the activated carbon, was the most important factor modulating the herbicide release.

    2011-03-01

    The scope of this project is to stabilize the abandoned coal storage area and redirect the storm water runoff from sanitary sewer system to the storm drain system. Currently, the existing storm water runoff is directed to a perimeter concrete drainage swale and collected in a containment basin. The collected water is then pumped to a treatment facility and after treatment, is discharged to the Y-12 sanitary sewer system. The existing drainage swale and collection basin along with silt fencing will be used during aggregate placement and grading to provide erosion and sediment control. Inlet protection will also be installed around existing structures during the storm water diversion construction. This project scope will include the installation of a non-woven geotextile fabric and compacted mineral aggregate base (paving optional) to stabilize the site. The geotextile specifications are provided on the vendor cut sheets in Appendix B. The installation of a storm water collection/retention area will also be installed on the southern side of the site in accordance with EPA Technical Guidance on Implementing the Stormwater Runoff Requirements for federal Projects under Section 438 of the Energy Independence and Security Act. The total area to be disturbed is approximately 2.5 acres. The order of activities for this Stormwater Pollution Prevention Plan (SWPPP) will be: (1) post notice of coverage (NOC) in a prominent display near entrance of the site; (2) install rain gauge on site or contact Y-12 Plant Shift Superintendent daily for Met tower rain gauge readings; (3) install stabilized construction exit on site; (4) install silt fencing along perimeter as indicated on the attached site plan; (5) regrade site; (6) install geotextile fabric and compacted mineral aggregate base; (7) install catch basin inlet protection where required; (8) excavate and lower existing catch basin tops, re-grade and asphalt to drain; and (9) when all disturbed areas are re-stabilized, remove

    This paper focuses on the current status of measures used to prevent, detect and respond to potential insiders at nuclear facilities in the Republic of KOREA. Measures against insiders are then analyzed based on IAEA guidelines. Insiders are able to take advantage of their access rights and knowledge of a facility to bypass dedicated security measures. They can also threaten cyber security, safety measures, and material control and accountancy (MC and A). Insiders are likely to have the time to plan their actions. In addition, they may work with an external adversary who shares their objectives. An insider threat is a great risk to a security system because of the access, authority, and special knowledge that someone within a facility possesses. Therefore, it is imperative that effective measures be taken to prevent insider incidents. A combination of preventive and protective measures offers the best solution to mitigating rogue elements within a facility.

    Food poisoning at care facilities for the elderly has been breaking out approximately ten cases per year nationwide from 2001 to 2010. Especially, it reflected the characteristics of food poisoning caused by noroviruses at a high rate. Usually we have been preventing from food poisoning by noroviruses working on existing measures such as temperature control of food materials, sanitary handlings of cooking tools and table wares, and so on. Additionally, the most effective measures to avoid secondary pollution at care facilities for the elderly is that all members at these facilities have to have a sense of crisis about food poisoning by noroviruses and managers at these facilities must take care of health control for all staff.

    The International Agency for Research on Cancer classified both outdoor air pollution and airborne particulate matter as carcinogenic to humans (Group 1) for lung cancer. There may be associations with cancer at other sites; however, the epidemiological evidence is limited. The aim of this study was to clarify whether ambient air pollution is associated with specific types of cancer other than lung cancer by examining associations of ambient air pollution with nonlung cancer death in the Cancer Prevention Study II (CPS-II). Analysis included 623,048 CPS-II participants who were followed for 22 y (1982-2004). Modeled estimates of particulate matter with aerodynamic diameter pollutant models including PM2.5 and NO2 and in three-pollutant models with O3. We observed no statistically significant positive associations with death from other types of cancer based on results from adjusted models. The results from this large prospective study suggest that ambient air pollution was not associated with death from most nonlung cancers, but associations with kidney, bladder, and colorectal cancer death warrant further investigation. https://doi.org/10.1289/EHP1249.

    The primary objective of this study was to determine whether the utilization rate of preventive oral health care services while senior adults were community-dwelling differed from the rate after those same senior adults were admitted to nursing facilities. A secondary objective was to evaluate other significant predictors of receipt of preventive oral health procedures after nursing facility entry. Iowa Medicaid claims from 2007-2014 were accessed for adults who were 68+ years upon entry to a nursing facility and continuously enrolled in Medicaid for at least three years before and at least two years after admission (n = 874). Univariate, bivariate and multivariable analyses were conducted. During the five years that subjects were followed, 52.8% never received a dental exam and 75.9% never received a dental hygiene procedure. More Medicaid-enrolled senior adults received ≥1 preventive dental procedure in the two years while residing in a nursing facility compared to the three years before entry. In multivariable analyses, the strongest predictor of preventive oral health care utilization after entry was the receipt of preventive oral health services before entry (p dental procedures in the two years after nursing facility entry was the receipt of dental procedures in the three years before entry while community-dwelling. This underscores the importance of the senior adult establishing a source of dental care while community-dwelling. © 2017 American Association of Public Health Dentistry.

    Firms that are dynamic and prepared to implement environmental strategies have a potential competitive advantage over their industry counterparts. Therefore, it is important to understand, what capabilities are required to implement proactive environmental strategies. The paper discusses the attributes of innovative capability required by firms in order to adopt pollution prevention and cleaner technology strategies. Empirical results show that process and behavioral innovativeness are required by firms to implement a pollution prevention strategy. In addition to process and behavioral innovativeness, firms need a top management with high risk-taking ability as well as market, product, and strategic innovativeness to implement a cleaner technology strategy. The paper proposes some important managerial implications on the basis of the above research findings. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Improving Pollution Prevention and Waste Minimization Program (PP/WMIN) technologies, actions, and culture could be an important cost-cutting step for the US Department of Energy (DOE). Communicating ideas, concepts, process changes, and achievements is essential for the success of this program. The need to openly communicate ideas and concepts in a cost-effective manner is essential in an organization that has such diverse components as research and development, weapons production, and power generation. This approach is in contrast to the historic DOE culture developed within the cold war period in which compartmentalization, independence, and secrecy were stressed. DOE has now recognized that for any pollution prevention program to be successful, the many diverse elements of the organization must share information. Avenues for such information exchange are examined in this report.

    Preventing the establishment of ectoparasitic poultry red mite (Dermanyssus gallinae) populations is key in ensuring welfare and egg production of laying hens and absence of allergic reactions of workers in poultry facilities. Using the Hazard Analysis and Critical Control Point method, a panel of experts identified hazards and associated risks concerning the introduction and spread of this mite in poultry facilities. Together we provide an overview of possible corrective actions that can be taken to prevent population establishment. Additionally, a checklist of the most critical control points has been devised as management tool for poultry farmers. This list was evaluated by Dutch and British poultry farmers. They found the checklist feasible and useful.

    Carbon-based aerogel fabricated from waste biomass is a potential absorbent material for solving organic pollution. Herein, the lightweight, hydrophobic and porous carbon aerogels (CAs) have been synthesized through freezing-drying and post-pyrolysis by using waste newspaper as the only raw materials. The as-prepared CAs exhibited a low density of 18.5 mg cm(-3) and excellent hydrophobicity with a water contact angle of 132° and selective absorption for organic reagents. The absorption capacity of CA for organic compounds can be 29-51 times its own weight. Moreover, three methods (e.g., squeezing, combustion, and distillation) can be employed to recycle CA and harvest organic pollutants. Combined with waste biomass as raw materials, green and facile fabrication process, excellent hydrophobicity and oleophilicity, CA used as an absorbent material has great potential in application of organic pollutant solvents absorption and environmental protection.

    Full Text Available Linear railroad facilities have been producing an adverse impact on the environment by polluting it with oil products for an extensive period of time. The authors of the article consider several mechanisms of contamination and the pattern of its spread into soils. Currently, areas that used to be unsuitable for development as urban lands for geological or environmental reasons are now being intensively developed. The study is exemplified by a city outstretched onto the complex terrain. Complex topography contemplates geological, tectonics-related, hydrological conditions, exogenous processes and anthropogenic factors. In this connection, the main purpose of the study is to analyze the geo-ecological factors that impact urban lands in complex geo-morphological conditions with a view to their functional use against minimal environmental risks to assure the most favorable conditions for humans. Towards this end, the authors have applied the following theoretical and practical methods of research, including a pilot study, namely (1 the geomorphological analysis of urban lands, (2 the monitoring and analysis of the anthropogenic impact produced onto various constituents of the environment, and (3 development of methods of functional use of urban lands in complex geomorphological conditions. The authors have monitored contaminated lands to develop their recommendations for their development in complex geomorphological conditions, namely: 1. Urban development planning should be performed with consideration for the geomorphological elements taken as a whole, as they are closely connected to one another. 2. Selection of methods of rehabilitation of urban lands must be preceded by the zoning of the territory based on its geological and environmental properties.

  11. Promoting pollution prevention through community-industry dialogues: the good neighbor model in Minnesota.

    This article examines five attempts by communities to promote pollution prevention through direct negotiations with local manufacturing plants. These projects were Good Neighbor Dialogues spearheaded by Citizens for a Better Environment-Minnesota, an environmental advocacy organization. Three community-company partnerships (a container plant, a foundry, and a cabinet manufacturer) were successful and two (a munitions plant and a petroleum refinery) were not. Successful dialogues all shared certain characteristics: the company was open to negotiating with the community; there was an effective "champion" within the company; a skilled, independent facilitator served as moderator; community participants received independent technical assistance; and both the company and community understood the value of cooperative environmental decision making. Results suggest that Good Neighbor Dialogues can, under the right settings and circumstances, be an effective mechanism for building social capital by fostering greater understanding and trust between companies and communities. They offer the prospect of community-company partnerships that promote pollution prevention and other environmental improvements, while at the same time reinforcing and amplifying traditional pollution control strategies.

    To ensure good air quality in Beijing during Asia-Pacific Economic Cooperation (APEC) China 2014, Beijing and its neighboring five provinces and the associated cities were combined under the Joint Prevention and Control of Atmospheric Pollution (JPCAP) program, which implemented rigorous cooperative emission reduction measures. The program was a unique and large-scale artificial experiment that showed that such measures can achieve excellent results, and it led to the popular "APEC blue" catchphrase (i.e., Beijing's skies became blue as pollution levels decreased). This artificial experiment provided the means to effectively conduct JPCAP strategies in the future. Accordingly, our research focused on the characteristics of the six primary pollutants in Beijing. We found that the JPCAP measures directly reduced concentrations of all pollutants except O3. Through correlation analysis, we found that the band distribution of the cities with strong correlations in PM2.5 and PM10 concentrations was affected by wind conditions. Therefore, JPCAP measures should account for specific seasonal and climatic conditions. Based on cluster analysis using the results from the correlation analysis, we divided 13 cities within a 300-km radius of Beijing into different groups according to the similarity of their PM2.5 and PM10 correlation coefficients. For JPCAP measures relevant to PM2.5 and PM10, we found differences in the degrees of collaboration among cities. Therefore, depending upon the pollutant type, the JPCAP strategy should account for the cities involved, the scope of the core area, and the optimal cities to involve in the collaborative efforts based on cost-effectiveness and collaborative difficulty among the involved cities.

    The herbicides chloridazon and metribuzin, identified as groundwater pollutants, were incorporated in lignin-based granules with different sizes to obtain controlled release formulations (CRFs) and reduce water pollution risk. Kinetics release tests in water and soil showed that the release rate of both from CRFs diminished in comparison to technical products. A linear correlation was obtained between the time taken for 50% of the active ingredient to be released (T{sub 50}) into water and granule size of the CRFs. Besides, a linear correlation was reached between T{sub 50} values in water and soil. Mobility experiments carried out in calcareous soil show that the use of lignin-based CRFs reduces the presence of both herbicides in the leachate compared to the technical grade products. The set of experiments developed in this research can be useful to design, prepare and evaluate formulations with CR properties which can reduce the pollution derived from the use of herbicides. - Preventing leaching of herbicides in soil using controlled release formulations based on a lignin matrix.

    2014-10-01

    Full Text Available This research paper aims to recommend control measures directed towards preventing and minimizing pollution, looking forward to the improvement of the environmental management on the sugar industry in Mexico. This issue has been put on hold due to the necessity to address the economic, social and technological issues affecting it over time. In order to better understand the productive process and the actual problem that the industry is facing, while proposing effective and possible actions for improvement, a sugar mill type was selected as a case of study. A comprehensive assessment of the production process for the standard sugar was made, considering the activities in the field and at the mill. The proposed measures in the sugar mill allowed savings in consumption of ground water average 3,620 cubic meters per day, during the period of study, reduction in solid waste generated average 325 kilograms per day by implementing a waste separation program, and reducing atmospheric emissions of particles acting as fuel for a boiler operated with bagasse. The prevention, minimization and pollution control measures proposed can be applied to other mills in the country with the appropriate adaptations.

  18. Waste minimization/pollution prevention study of high-priority waste streams

    1994-03-01

    Although waste minimization has been practiced by the Metals and Ceramics (M&C) Division in the past, the effort has not been uniform or formalized. To establish the groundwork for continuous improvement, the Division Director initiated a more formalized waste minimization and pollution prevention program. Formalization of the division`s pollution prevention efforts in fiscal year (FY) 1993 was initiated by a more concerted effort to determine the status of waste generation from division activities. The goal for this effort was to reduce or minimize the wastes identified as having the greatest impact on human health, the environment, and costs. Two broad categories of division wastes were identified as solid/liquid wastes and those relating to energy use (primarily electricity and steam). This report presents information on the nonradioactive solid and liquid wastes generated by division activities. More specifically, the information presented was generated by teams of M&C staff members empowered by the Division Director to study specific waste streams.

    US industry produces about 12 billion tons of waste a year, or two-thirds of the waste generated in the US. The costs of handling and disposing of these wastes are significant, estimated to be between $25 and $43 billion in 1991, and represent an increase of 66% since 1986. US industry also uses about one-third of all energy consumed in the nation, which adds to the environmental burden. Industrial wastes affect the environmental well-being of the nation and, because of their growing costs, the competitive abilities of US industry. As part of a national effort to reduce industrial wastes, the US Congress passed the Energy Policy Act (EPAct, P.L. 102-486). Section 2108, subsections (b) and (c), of EPAct requires the Department of Energy (DOE) to identify opportunities to demonstrate energy efficient pollution prevention technologies and processes; to assess their availability and the energy, environmental, and cost effects of such technologies; and to report the results. Work for this report clearly pointed to two things, that there is insufficient data on wastes and that there is great breadth and diversity in the US industrial sector. This report identifies: information currently available on industrial sector waste streams, opportunities for demonstration of energy efficient pollution prevention technologies in two industries that produce significant amounts of waste--chemicals and petroleum, characteristics of waste reducing and energy saving technologies identifiable in the public literature, and potential barriers to adoption of waste reducing technologies by industry.

    Climate change, air pollution, temperature increase and other environmental variables are modifying air quality, contributing to the increase of prevalence of allergic respiratory diseases. Allergies are complex diseases characterized by multilevel interactions between individual susceptibility, response to immune modulation and environmental exposures to physical, chemical and biological agents. Occupational allergies introduce a further complexity to these relationships by adding occupational exposure to both the indoor and outdoor ones in the living environment. The aim of this paper is to overview climate-related allergy affecting environmental and occupational health, as literature data are scanty in this regard, and to suggest a management model of this risk based on a multidisciplinary approach, taking the case of biological pollution, with details on exposure and prevention. The management of climate-related occupational allergy should take into account preventive health strategies, environmental, public and occupational interventions, as well as to develop, implement, evaluate, and improve guidelines and standards protecting workers health under changing climatic conditions; new tools and strategies based on local conditions will have to be developed. Experimental studies and acquisition of environmental and personal data have to be matched to derive useful information for the scope of occupational health and safety.

    Older people living in residential aged care facilities (RACFs) are at considerably higher risk of suffering fractures than older people living in the community. When admitted to RACFs, patients should be assessed for fracture risk to ensure early implementation of effective fracture prevention measures. Routine or regular determination of calcium and phosphate serum levels in institutionalised older people is not indicated. Opinion is divided about the value of routine measurements of serum concentrations of 25-hydroxyvitamin D, parathyroid hormone and bone turnover markers. The non-pharmacological approach to fracture prevention includes multifactorial programs of falls prevention and the use of hip protectors. Vitamin D supplementation is recommended for all patients in RACFs. Dietary calcium intake should be optimised (1200-1500 mg per day is recommended) and supplementation offered to those with inadequate intake. The decision to prescribe calcium supplements should be guided by patients' tolerance, whether or not they have a history of kidney stones, and emerging data about its cardiovascular safety. Bisphosphonates are the first-choice pharmacological agents for fracture prevention in older persons at high risk. Intravenous administration is as efficient as oral and has the significant advantage of better adherence. Use of strontium ranelate has not been tested on people in RACFs, but evidence in the "old-old" (those aged 75 years and older) suggests it could be a therapeutic option for fracture prevention in this setting. In general, teriparatide should not be considered as a first-line treatment for fracture prevention, particularly for people in RACFs.

    This report was developed from experiences with three New Jersey firms and is intended to be a guide for conducting analyses on resource (energy and raw materials) utilization and pollution (solid waste, air and water emissions) prevention in plastics processing plants. The protocol is written on the assumption that the analysis is to be done by an outside agency such as a consulting firm, but it also can be used for internal audits by plant teams. Key concepts in this analysis were adapted from life cycle analysis. Because of the small sample of companies studied, the results have to be considered high preliminary, but some of the conclusions will probably be confirmed by further work.

  9. Pollution prevention benefits of non-hazardous shielding glovebox gloves - 11000

    Radiation shielding is commonly used to protect the glovebox worker from unintentional direct and secondary radiation exposure, while working with plutonium-238 and plutonium-239. Shielding glovebox gloves are traditionally composed of lead-based materials, i.e., hazardous waste. This has prompted the development of new, non-hazardous shielding glovebox gloves. No studies, however, have investigated the pollution prevention benefits of these new glovebox gloves. We examined both leaded and non-hazardous shielding glovebox gloves. The nonhazardous substitutes are higher in cost, but this is offset by eliminating the costs associated with onsite waste handling of Resource Conservation and Recovery Act (RCRA) items. In the end, replacing lead with non-hazardous substitutes eliminates waste generation and future liability.

    Full Text Available Abstract Lead is an old environmental metal which is presented everywhere and lead poisoning is an important health issue in many countries in the world including Iran. It is known as a silent environmental disease which can have life-long adverse health effects. In children, the most vulnerable population, mental development of children health effects is of the greatest influence. Low level lead exposure can significantly induce motor dysfunctions and cognitive impairment in children. The sources of lead exposure vary among countries. Occupational lead exposure is an important health issue in Iran and mine workers, employees of paint factories, workers of copying centers, drivers, and tile making factories are in higher risk of lead toxicity. Moreover lead processing industry has always been a major of concern which affects surface water, drinking waters, and ground waters, even water of Caspian Sea, Persian Gulf and rivers due to increasing the number of industries in vicinity of rivers that release their waste discharges into river or sea. In addition, lead contamination of soil and air especially in vicinity of polluted and industrialized cities is another health problem in Iran. Even foods such as rice and fishes, raw milk, and vegetables which are the most common food of Iranian population are polluted to lead in some area of Iran. Adding lead to the opium is a recently health hazard in Iran that has been observed among opium addicts. There are few studies evaluated current status of lead exposure and toxicity in the Iranian children and pregnant women which should be taken into account of authorities. We recommend to identify sources, eliminate or control sources, and monitor environmental exposures and hazards to prevent lead poisoning.

  1. Reduction of femoral fractures in long-term care facilities: the Bavarian fracture prevention study.

    Directory of Open Access Journals (Sweden)

    Clemens Becker

    Full Text Available BACKGROUND: Hip fractures are a major public health burden. In industrialized countries about 20% of all femoral fractures occur in care dependent persons living in nursing care and assisted living facilities. Preventive strategies for these groups are needed as the access to medical services differs from independent home dwelling older persons at risk of osteoporotic fractures. It was the objective of the study to evaluate the effect of a fall and fracture prevention program on the incidence of femoral fracture in nursing homes in Bavaria, Germany. METHODS: In a translational intervention study a fall prevention program was introduced in 256 nursing homes with 13,653 residents. The control group consisted of 893 nursing homes with 31,668 residents. The intervention consisted of staff education on fall and fracture prevention strategies, progressive strength and balance training, and on institutional advice on environmental adaptations. Incident femoral fractures served as outcome measure. RESULTS: In the years before the intervention risk of a femoral fracture did not differ between the intervention group (IG and control group (CG. During the one-year intervention period femoral fracture rates were 33.6 (IG and 41.0/1000 person years (CG, respectively. The adjusted relative risk of a femoral fracture was 0.82 (95% CI 0.72-0.93 in residents exposed to the fall and fracture prevention program compared to residents from CG. CONCLUSIONS: The state-wide dissemination of a multi-factorial fall and fracture prevention program was able to reduce femoral fractures in residents of nursing homes.

    This research investigated the removal and fate of 16 USEPA priority pollutant polycyclic aromatic hydrocarbons (PAHs) from urban stormwater runoff through a bioretention cell. Bioretention is an infiltration/filtration practice containing a mixed layer of about 90 cm of soil, sand, and organic matter, planted with appropriate vegetation. Field water quality monitoring and bioretention media core analyses were performed. The results indicate that bioretention is a promising management practice to control runoff PAH pollutants. The PAH event mean concentration (EMC) reduction ranged from 31 to 99%, with a mean discharge EMC of 0.22 microg/L. The mass load decreased from a mean value of 0.0180 kg/ha yr to 0.0025 kg/ha yr, suggesting an average PAH mass load reduction of 87% to the discharging watershed. The most dominant PAH species monitored were fluoranthene and pyrene. Influent PAHs indicated strong affiliation with runoff total suspended solids (TSS). As such, PAH removal positively correlated with TSS removal. Low rainfall depth was associated with high influent PAH concentration and resulted in favorable PAH removal. Source investigation suggested that the PAHs measured in the monitored cell were from pyrogenic sources, likely resulting from vehicle combustion processes. Sealers used in parking lots and driveway coatings were also a possible source of PAHs. Media core analyses indicated that the intercepted PAH compounds transported only a few centimeters vertically in the soil media near the runoff entrance location, suggesting that a shallow cell design may be adequate for systems focusing on PAH removal.

    One approach to the prevention of pollution and the reduction of worker exposure from conventional solvents is the use of less hazardous substitutes. One of the more novel substitutes is carbon dioxide. Although carbon dioxide is a gas at ordinary conditions, it can be liquified by application of pressure. In its supercritical state, it exhibits good solvent properties. Separation of the carbon dioxide from the extracted materials can be accomplished by pressure reduction, adsorption onto activated carbon, or with a membrane process, e.g., decaffeination of coffee. This paper presents a brief overview of the university and federal laboratory collaborative efforts focusing on processes using supercritical carbon dioxide as a substitute for hazardous solvents. The SCCO2 technology applications under this program include extraction of natural pharmaceutical materials, phase-transfer catalysis, solvent replacement in chemical synthesis, temperature-solubility relationships, and separation of organic materials from soils and slurries. A paper on the extraction of heavy metals with SCCO2 was presented by Ataai et.al. at the 87th National Meeting, A&WMA. This work is also supported by the EPA.

    We performed a screening investigation to assess the human health risks of the Integrated Waste Management Facility (IWMF: mechanical–biological treatment (MBT) plant plus municipal solid waste incinerator (MSWI); Ecoparc-3) of Barcelona (Spain). Air concentrations of pollutants potentially released by the MBT plant (VOCs and bioaerosols) and the MSWI (trace elements, PCDD/Fs and PCBs) were determined. Trace elements, PCDD/Fs and PCBs were also analyzed in soil samples. The concentrations of trace elements and bioaerosols were similar to those previously reported in other areas of similar characteristics, while formaldehyde was the predominant VOC. Interestingly, PCDD/F concentrations in soil and air were the highest ever reported near a MSWI in Catalonia, being maximum concentrations 10.8 ng WHO-TEQ/kg and 41.3 fg WHO-TEQ/m{sup 3}, respectively. In addition, there has not been any reduction in soils, even after the closure of a power plant located adjacently. Human health risks of PCDD/F exposure in the closest urban nucleus located downwind the MSWI are up to 10-times higher than those nearby other MSWIs in Catalonia. Although results must be considered as very preliminary, they are a serious warning for local authorities. We strongly recommend to conduct additional studies to confirm these findings and, if necessary, to implement measures to urgently mitigate the impact of the MSWI on the surrounding environment. We must also state the tremendous importance of an individual evaluation of MSWIs, rather than generalizing their environmental and health risks. - Highlights: • Health risks of an Integrated Waste Management Facility in Catalonia are assessed. • PCDD/F exposure near this facility is up to 10-times higher than that near others. • Environmental monitoring of incineration plants should be performed case-by-case. • Since results are very preliminary, confirmatory studies should be conducted.

    The Oak Ridge National Laboratory Outdoor UltraViolet-B (UV-B) Exposure and Monitoring Facility was developed in 1980 to provide well-controlled and -monitored exposure of specific terrestrial plant. species to elevated levels of ultraviolet (UV) radiation. The introduction of various anthropogenic agents into the earth`s stratosphere has resulted in a decrease in the volume of ozone (O{sub 3}) present here. The decrease in O{sub 3} has resulted in an increase in the level of UV radiation reaching thee earth`s surface. Of particular interest is the level of UV-B, because it has the most detrimental effect on living tissue. A thorough understanding of the effects of elevated levels of UV-B on living tissue is critical to the formulation of economic policy regarding production of such agents and alternative strategies. The UV region of interest is referred to as UV-B and corresponds to radiation with a wavelength of 290 to 320 nm. Design, operation, and performance of the automated generation, exposure, and monitoring system are described. The system has proved to be reliable and easy to maintain and operate, and it provides significant flexibility in exposure programs. The system software is described, and detailed listings are provided. The ability to expose plants to controlled set point percentages of UV-B above the ambient level was developed.

    Modern manufacturing of printed wiring boards (PWBs) involves extensive use of various hazardous chemicals in different manufacturing steps such as board preparation, circuit design transfer, etching and plating processes. Two complementary environmental screening methods developed by the U.S. EPA, namely: (i) the Tool for the Reduction and Assessment of Chemical and Other Environmental Impacts (TRACI) and (ii) Risk-Screening Environmental Indicators (RSEI), are used to quantify geographic and chemical environmental impacts in the U.S. PWB manufacturing industry based on Toxics Release Inventory (TRI) data. Although the release weight percentages of industrial chemicals such as methanol, glycol ethers and dimethylformamide comprise the larger fraction of reported air and water emissions, results indicate that lead, copper and their compounds' releases correspond to the highest environmental impact from toxicity potentials and risk-screening scores. Combining these results with further knowledge of PWB manufacturing, select alternative chemical processes and materials for pollution prevention are discussed. Examples of effective pollution prevention options in the PWB industry include spent etchant recovery technologies, and process and material substitutions. In addition, geographic assessment of environmental burden highlights states where promotion of pollution prevention strategies and emissions regulations can have the greatest effect to curb the PWB industry's toxic release impacts.

    The paper presents the assessment of tooth decay prevalence in clinically homogenous groups of children receiving long-term preventive program (PP) in school dental facilities. Five-years PP were introduced in clinical practice in 2 Moscow schools. Preventive treatment was performed by dental hygienist. The results show that systematic preventive treatment in school dental offices starting from elementary school allows reducing dental caries incidence 46-53% and stabilize the incidence of caries complications. It should be mentioned though that analysis of individualized outcomes proves heterogeneity of study results despite of equal conditions of PP. Potentially significant hence is early diagnostics and treatment of initial caries forms as demineralization foci, especially in children with intensive tooth decay. Optimization of pediatric dentist and dental hygienist activity in school dental facilities is the main factor of caries prevention efficiency.

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

    Lam, Carl

    Due to technology proliferation, the environmental burden attributed to the production, use, and disposal of hazardous materials in electronics have become a worldwide concern. The major theme of this dissertation is to develop and apply hazardous materials assessment tools to systematically guide pollution prevention opportunities in the context of electronic product design, manufacturing and end-of-life waste management. To this extent, a comprehensive review is first provided on describing hazard traits and current assessment methods to evaluate hazardous materials. As a case study at the manufacturing level, life cycle impact assessment (LCIA)-based and risk-based screening methods are used to quantify chemical and geographic environmental impacts in the U.S. printed wiring board (PWB) industry. Results from this industrial assessment clarify priority waste streams and States to most effectively mitigate impact. With further knowledge of PWB manufacturing processes, select alternative chemical processes (e.g., spent copper etchant recovery) and material options (e.g., lead-free etch resist) are discussed. In addition, an investigation on technology transition effects for computers and televisions in the U.S. market is performed by linking dynamic materials flow and environmental assessment models. The analysis forecasts quantities of waste units generated and maps shifts in environmental impact potentials associated with metal composition changes due to product substitutions. This insight is important to understand the timing and waste quantities expected and the emerging toxic elements needed to be addressed as a consequence of technology transition. At the product level, electronic utility meter devices are evaluated to eliminate hazardous materials within product components. Development and application of a component Toxic Potential Indicator (TPI) assessment methodology highlights priority components requiring material alternatives. Alternative

    Air pollution control (APC) residues from energy-from-waste (EfW) are alkaline (corrosive) and contain high concentrations of metals, such as zinc and lead, and soluble salts, such as chlorides and sulphates. The EPA 3050B-extractable concentrations of 66 elements, including critical elements of strategic importance for advanced electronics and energy technologies, were determined in eight APC residues from six UK EfW facilities. The concentrations of Ag (6-15 mg/kg) and In (1-13 mg/kg), as well as potential pollutants, especially Zn (0.26-0.73 wt.%), Pb (0.05-0.2 wt.%), As, Cd, Cu, Mo, Sb, Sn and Se were found to be enriched in all APC residues compared to average crustal abundances. Results from a combination of scanning electron microscopy with energy dispersive X-ray spectroscopy and also powder X-ray diffraction, thermal analysis and Fourier transform infrared spectroscopy give an exceptionally full understanding of the mineralogy of these residues, which is discussed in the context of other results in the literature. The present work has shown that the bulk of the crystalline phases present in the investigated APC residues include Ca-based phases, such as CaCl(x)OH(2-x), CaCO3, Ca(OH)2, CaSO4, and CaO, as well as soluble salts, such as NaCl and KCl. Poorly-crystalline aragonite was identified by FTIR. Sulphur appears to have complex redox speciation, presenting as both anhydrite and hannebachite in some UK EfW APC residues. Hazardous elements (Zn and Pb) were widely associated with soluble Ca- and Cl-bearing phases (e.g. CaCl(x)OH(2-x) and sylvite), as well as unburnt organic matter and aluminosilicates. Specific metal-bearing minerals were also detected in some samples: e.g., Pb present as cerussite; Zn in gahnite, zincowoodwardite and copper nickel zinc oxide; Cu in tenorite, copper nickel zinc oxide and fedotovite. Aluminium foil pieces were present and abundantly covered by fine phases, particularly in any cracks, probably in the form of Friedel's salt

    The herbicides chloridazon and metribuzin, identified as groundwater pollutants, were incorporated in lignin-based granules with different sizes to obtain controlled release formulations (CRFs) and reduce water pollution risk. Kinetics release tests in water and soil showed that the release rate of both from CRFs diminished in comparison to technical products. A linear correlation was obtained between the time taken for 50% of the active ingredient to be released (T(50)) into water and granule size of the CRFs. Besides, a linear correlation was reached between T(50) values in water and soil. Mobility experiments carried out in calcareous soil show that the use of lignin-based CRFs reduces the presence of both herbicides in the leachate compared to the technical grade products. The set of experiments developed in this research can be useful to design, prepare and evaluate formulations with CR properties which can reduce the pollution derived from the use of herbicides.

    Occupational health and pollution prevention, although conceptually linked by the common goals of preventing exposure to toxic materials and lowering risk functions, have been largely confined to separate patterns of practice and professional development. Some analysts see this as a missed opportunity for synergy and raising the level of protection afforded to both the worker and the ambient environment. By using current specific examples we show how strategies that integrate pollution prevention and occupational health practices can be effective at reducing chemical exposures and environmental releases beyond the levels normally achieved using traditional methods alone. Similarities in approaches to addressing chemical hazards at the source, are analyzed in the context of U.S. policy and recent state and federal initiatives. Results obtained from the analysis of multi-pathway risks found within the automotive refinishing sector serve as examples of how best to select engineering and control strategies. Industry survey, metal speciation, and methylene chloride usage data from studies conducted in Rhode Island, coupled with case reports from other settings, demonstrate that opportunities exist to concurrently mitigate multiple environmental and occupational health hazards. The collaborative initiatives undertaken in the automotive refinishing industry sector demonstrate that an integrated environmental and occupational health approach can more effectively address multiple chemical releases and workplace exposures. Such synergy should be advanced in the future by similar integrative and collaborative strategies. Copyright 2003 Wiley-Liss, Inc.

    In today`s competitive work environment it is becoming increasingly important for industry to comply with environmental regulations and standards while minimizing cost on pollution control systems. This often requires innovative new solutions to existing environmental challenges. Strategic environmental planning and process optimization are key elements in cost-effective environmental management. The permanent total enclosure can be a useful tool in the strategic environmental planning process. This paper discusses the installation of a permanent total enclosure at a southeastern printing and publishing industry. By constructing the total enclosure the industry was able to streamline the permitting process and reduce pollutant emissions while simultaneously reducing cost and saving money.

    Decommissioning of nuclear facilities has to be accomplished by assuring the safety of workers. Decommissioning workers need familiarization with working environments because working environment is under high radioactivity and work difficulty during decommissioning of nuclear facilities. On-the-job training of decommissioning works could effectively train decommissioning workers but this training approach could consume much costs and poor modifications of scenarios. The efficiency of virtual training system could be much better than that of physical training system. This paper was intended to develop the training system to prevent accidents for decommissioning of nuclear facilities. The requirements for the training system were drawn. The data management modules for the training system were designed. The training system of decommissioning workers was developed on the basis of virtual reality which is flexibly modified. The visualization and measurement in the training system were real-time done according as changes of the decommissioning scenario. It can be concluded that this training system enables the subject to improve his familiarization about working environments and to prevent accidents during decommissioning of nuclear facilities. In the end, the safety during decommissioning of nuclear facilities will be guaranteed under the principle of ALARA.

    Government-led pollution prevention programs tend to focus on large businesses due to their potential to pollute larger quantities, therefore leaving a gap in programs targeting small and home-based businesses. In light of this gap, we set out to determine if a voluntary, peer education approach led by female, Hispanic community health workers (promotoras) can influence small and home-based businesses to implement pollution prevention strategies on-site. This paper describes a partnership between promotoras from a non-profit organization and researchers from a university working together to reach these businesses in a predominately Hispanic area of Tucson, Arizona. From 2008 to 2011, the promotora-led pollution prevention program reached a total of 640 small and home-based businesses. Program activities include technical trainings for promotoras and businesses, generation of culturally and language appropriate educational materials, and face-to-face peer education via multiple on-site visits. To determine the overall effectiveness of the program, surveys were used to measure best practices implemented on-site, perceptions towards pollution prevention, and overall satisfaction with the industry-specific trainings. This paper demonstrates that promotoras can promote the implementation of pollution prevention best practices by Hispanic small and home-based businesses considered "hard-to-reach" by government-led programs.

    Full Text Available Government-led pollution prevention programs tend to focus on large businesses due to their potential to pollute larger quantities, therefore leaving a gap in programs targeting small and home-based businesses. In light of this gap, we set out to determine if a voluntary, peer education approach led by female, Hispanic community health workers (promotoras can influence small and home-based businesses to implement pollution prevention strategies on-site. This paper describes a partnership between promotoras from a non-profit organization and researchers from a university working together to reach these businesses in a predominately Hispanic area of Tucson, Arizona. From 2008 to 2011, the promotora-led pollution prevention program reached a total of 640 small and home-based businesses. Program activities include technical trainings for promotoras and businesses, generation of culturally and language appropriate educational materials, and face-to-face peer education via multiple on-site visits. To determine the overall effectiveness of the program, surveys were used to measure best practices implemented on-site, perceptions towards pollution prevention, and overall satisfaction with the industry-specific trainings. This paper demonstrates that promotoras can promote the implementation of pollution prevention best practices by Hispanic small and home-based businesses considered “hard-to-reach” by government-led programs.

    Residents of long-term care facilities are highly susceptible to norovirus gastroenteritis, and each facility is concerned about the need to implement norovirus infection control. Among control measures, personal protective equipment (PPE), such as disposable gloves and masks, plays a major role in reducing infectious spread. However, the preparation status of PPE in facilities before infection outbreaks has not been reported. The aim was to clarify the implementation status of preventive measures for norovirus gastroenteritis and the cost of preparing the necessary PPE in long-term care facilities. A questionnaire survey of facilities affiliated with the Kyoto Prefecture and Osaka Prefecture branches of the Japan Association of Geriatric Health Services Facilities was conducted. The survey items were the characteristics of the facility, whether preventive measures had been implemented for norovirus gastroenteritis from October through the following March in both 2009 and 2010, and the quantities and unit prices of PPE prepared for preventive measures. Twenty-six (11.2%) of 232 surveyed facilities (as of August 2011) answered the survey. Among them, 24 (92.3%) in 2009 and 25 (96.2%) in 2010 reported having implemented preventive measures for norovirus gastroenteritis, while 21 facilities (80.8%) in 2009 and 22 facilities (84.6%) in 2010 had prepared PPE. The median total cost for preparing the PPE needed for the preventive measures was US $2601 (range US $221-9192) in 2009 and US $3904 (range US $305-6427) in 2010. Although the results need careful interpretation because of the low response rate, most of the surveyed long-term care facilities had implemented preventive measures for norovirus gastroenteritis. However, the cost of preparing the PPE needed for the preventive measures varied among the facilities. © 2017 John Wiley & Sons, Ltd.

    Benzene, toluene and xylenes (BTX) air pollution is a very important topic for environmental health, due to the toxicity and/or mutagenic or carcinogenic properties of these aromatics and the commercialisation of the unleaded gasoline containing amount of BTX. We measured BTX in the air of Turin city, the capital of Piedmont region (north-western Italy), during 10 years, from 1989 to 1998. The sampling site selected was Lagrange Street (LS), an 'urban canyon' placed in the centre of the city. The behaviour of BTX in LS was conditioned by some local and national legislative measures enforced during 1990s for the reduction of automotive traffic and BTX air pollution, respectively. Taking into account the existence of similar measures undertaken also in several cities in the developed countries, largely described but never discussed, the aim of this study was to verify in LS the preventive effects of these regulatory actions by means of a longitudinal survey extended over 10 years. Results obtained in Lagrange Street highlight seasonal trends, typical of this kind of pollutants, and an important reduction (from 42.6 to 15.9ppbv) of aromatic hydrocarbons (sum of benzene, toluene and xylenes) in atmospheric air from 1990 to 1997. In particular, the annual level of benzene in air showed a mean from 9.2ppbv in 1990 to 2.0ppbv in 1997, almost half of the 3.1ppbv imposed by law since 31 December 1998. In conclusion, the present findings induce a consistent optimism about the usefulness and the effectiveness of these types of regulatory actions enforced to reduce the human exposure to BTX, which could be extended also to other trafficated sites where the aromatics air pollution has to be reduced.

    Full Text Available Agricultural plastic film mulching is one of important technologies, but the plastic film pollution has been a serious issue for agri-cultural sustainable development in China. System analysis of this technique and its residue pollution and control ways have vital practicalsignificance for rational application of agricultural plastil film. In this paper, on the basis of our previous work,agricultural plastic filmmulching, its residue pollution and control technologies were concluded. Some important conclusions were found that, the amount of plasticfilm and mulching area had kept increasing with annual increasing rate about 8% since the 80s of the 20th century. From 1991 to 2011, thedensity of plastic film utilized increased 3-10 times, but it has very sharply different spatial pattern in different province. In general, the northand west China has high value, and the increase rate is also huge in the past 20 years. The crops of utilized mulching plastic film have extendedfrom cash crops to grain crops, and the order of crop area is followed by maize, vegetable, cotton, tobacco and peanut. The main functions ofmulching plastic film are keeping soil moisture and increasing soil temperature, against weeds and insect. At the same time, its side effectsappear with continuous utilization. The main problems are residues left in soil to destroy soil structure, impress soil permeability, impede seedgermination as well as water and nutrients uptaking, and block crop root system development. It has very serious pollution for the field utilizedplastic mulching film for long term. The residual amount in soil is about 71.9-259.1 kg·hm-2, and has sharply spatial difference. The residualamount in soil. In Northwest China, is more serious than that in North China and Southwest China. Because of difference of tillage and appli-canon ways, there are great differences on the area and shape of the plastic film piece left in soil. The main types of shapes are flaky

    Background Assisted Living Facilities (ALFs) provide housing and care to persons unable to live independently, and who often have increasing medical needs. Disease outbreaks illustrate challenges of maintaining adequate resident protections in these facilities. Objectives Describe current state laws on assisted living admissions criteria, medical oversight, medication administration, vaccination requirements, and standards for infection control training. Methods We abstracted laws and regulations governing assisted living facilities for the 50 states using a structured abstraction tool. Selected characteristics were compared according to the time period in which the regulation took effect. Selected state health departments were queried regarding outbreaks identified in assisted living facilities. Results Of the 50 states, 84% specify health-based admissions criteria to assisted living facilities. 60% require licensed healthcare professionals to oversee medical care. 88% specifically allow subcontracting with outside entities to provide routine medical services onsite, and 64% address medication administration by assisted living facility staff. 54% specify requirements for some form of initial infection control training for all staff; 50% require reporting of disease outbreaks to the health department. 30% offered or required vaccines to staff; 15% of states offered or required vaccines to residents. Eleven states identified approximately 1500 outbreaks from 2010–2013, with influenza or norovirus infections predominating. Conclusions There is wide variation in how assisted living facilities are regulated in the United States. States may wish to consider regulatory changes that assure safe healthcare delivery, and minimize risks of infections, outbreaks of disease, and other forms of harm among assisted living residents.

    Clean sampling and analysis procedures were used to quantify more than 70 inorganic constituents, including 35 potentially toxic or hazardous constituents, organic carbon, and other characteristics of untreated (influent) and treated (effluent) coal-mine discharges (CMD) at 38 permitted coal-mining or coal-processing facilities in the bituminous coalfield and 4 facilities in the anthracite coalfield of Pennsylvania. Of the 42 facilities sampled during 2011, 26 were surface mines, 11 were underground mines, and 5 were coal refuse disposal operations. Treatment of CMD with caustic soda (NaOH), lime (CaO or Ca(OH)2), flocculent, or limestone was ongoing at 21%, 40%, 6%, and 4% of the facilities, respectively; no chemicals were added at the remaining facilities. All facilities with CMD treatment incorporated structures for active or passive aeration and settling of metal-rich precipitate.

    This report details a study into the demand response potential of a large wastewater treatment facility in San Francisco. Previous research had identified wastewater treatment facilities as good candidates for demand response and automated demand response, and this study was conducted to investigate facility attributes that are conducive to demand response or which hinder its implementation. One years' worth of operational data were collected from the facility's control system, submetered process equipment, utility electricity demand records, and governmental weather stations. These data were analyzed to determine factors which affected facility power demand and demand response capabilities The average baseline demand at the Southeast facility was approximately 4 MW. During the rainy season (October-March) the facility treated 40% more wastewater than the dry season, but demand only increased by 4%. Submetering of the facility's lift pumps and centrifuges predicted load shifts capabilities of 154 kW and 86 kW, respectively, with large lift pump shifts in the rainy season. Analysis of demand data during maintenance events confirmed the magnitude of these possible load shifts, and indicated other areas of the facility with demand response potential. Load sheds were seen to be possible by shutting down a portion of the facility's aeration trains (average shed of 132 kW). Load shifts were seen to be possible by shifting operation of centrifuges, the gravity belt thickener, lift pumps, and external pump stations These load shifts were made possible by the storage capabilities of the facility and of the city's sewer system. Large load reductions (an average of 2,065 kW) were seen from operating the cogeneration unit, but normal practice is continuous operation, precluding its use for demand response. The study also identified potential demand response opportunities that warrant further study: modulating variable-demand aeration loads, shifting

    In spite of the consideration that toxicity testing is a reduced approach to measure the effects of pollutants on ecosystems, the early-life-stage (ELS) tests have evident ecological relevance because they reflect the possible reproductive impairment of the natural populations. The procedure and validation of Crassostrea rhizophorae embryonic development test have shown that it meets the same precision as other U.S. EPA tests, where EC(50) is generally used as a toxicological endpoint. However, the recognition that EC(50) is not the best endpoint to assess contaminant effects led U.S. EPA to recently suggest EC(25) as an alternative to estimate xenobiotic effects for pollution prevention. To provide reliability to the toxicological test results on C. rhizophorae embryos, the present work aimed to establish the critical effect level for this test organism, based on its reaction to reference toxicants, by using the statistical method proposed by Norberg-King (Inhibition Concentration, version 2.0). Oyster embryos were exposed to graded series of reference toxicants (ZnSO(4) x 7H(2)O; AgNO(3); KCl; CdCl(2)H(2)O; phenol, 4-chlorophenol and dodecyl sodium sulphate). Based on the obtained results, the critical value for C. rhizophorae embryonic development test was estimated as EC(15). The present research enhances the emerging consensus that ELS tests data would be adequate for estimating the chronic safe concentrations of pollutants in the receiving waters. Based on recommended criteria and on the results of the present research, zinc sulphate and 4-chlorophenol have been pointed out, among the inorganic and organic compounds tested, as the best reference toxicants for C. rhizophorae ELS-test.

    2010-02-01

    Full Text Available Abstract Background Falls are common adverse events in residential care facilities. Commonly reported figures indicate that at least 50% of residents fall in a 12 month period, and that this figure is substantially higher for residents with dementia. This paper reports the protocol of a project which aims to implement evidence based falls prevention strategies in nine residential aged care facilities (RACFs in Australia. The facilities in the study include high and low care, small and large facilities, metropolitan and regional, facilities with a specific cultural focus, and target groups recognised as being more challenging to successful implementation of falls prevention practice (e.g. residents with dementia. Methods The project will be conducted from November 2007-November 2009. The project will involve baseline scoping of existing falls rates and falls prevention activities in each facility, an action research process, interactive falls prevention training, individual falls risk assessments, provision of equipment and modifications, organisation based steering committees, and an economic evaluation. In each RACF, staff will be invited to join an action research group that will lead the process of developing and implementing interventions designed to facilitate an evidence based approach to falls management in their facility. In all RACFs a pre/post design will be adopted with a range of standardised measures utilised to determine the impact of the interventions. Discussion The care gap in residential aged care that will be addressed through this project relates to the challenges in implementing best practice falls prevention actions despite the availability of best practice guidelines. There are numerous factors that may limit the uptake of best practice falls prevention guidelines in residential aged care facilities. A multi-factorial individualised (to the specific requirements of each facility approach will be used to develop and

    Full Text Available BACKGROUND: Influenza is an important cause of morbidity and mortality for frail older people. Whilst the antiviral drug oseltamivir (a neuraminidase inhibitor is approved for treatment and prophylaxis of influenza during outbreaks, there have been no trials comparing treatment only (T versus treatment and prophylaxis (T&P in Aged Care Facilities (ACFs. Our objective was to compare a policy of T versus T&P for influenza outbreaks in ACFs. METHODS AND FINDINGS: We performed a cluster randomised controlled trial in 16 ACFs, that followed a policy of either "T"-oseltamivir treatment (75 mg twice a day for 5 days-or "T&P"-treatment and prophylaxis (75 mg once a day for 10 days for influenza outbreaks over three years, in addition to enhanced surveillance. The primary outcome measure was the attack rate of influenza. Secondary outcomes measures were deaths, hospitalisation, pneumonia and adverse events. Laboratory testing was performed to identify the viral cause of influenza-like illness (ILI outbreaks. The study period 30 June 2006 to 23 December 2008 included three southern hemisphere winters. During that time, influenza was confirmed as the cause of nine of the 23 ILI outbreaks that occurred amongst the 16 ACFs. The policy of T&P resulted in a significant reduction in the influenza attack rate amongst residents: 93/255 (36% in residents in T facilities versus 91/397 (23% in T&P facilities (p=0.002. We observed a non-significant reduction in staff: 46/216 (21% in T facilities versus 47/350 (13% in T&P facilities (p=0.5. There was a significant reduction in mean duration of outbreaks (T=24 days, T&P=11 days, p=0.04. Deaths, hospitalisations and pneumonia were non-significantly reduced in the T&P allocated facilities. Drug adverse events were common but tolerated. CONCLUSION: Our trial lacked power but these results provide some support for a policy of "treatment and prophylaxis" with oseltamivir in controlling influenza outbreaks in ACFs. TRIAL

    This work focuses an integrated approach based on Sea-Use-Map (SUM), backed by a permanent monitoring system (C-CEMS-Civitavecchia Coastal Environmental Monitoring System). This tool supports the management of the marine coastal area, contributing substantially to ecosystem benefits evaluation and to minimize pollution impacts. Within the Blue Growth strategy, the protection of marine ecosystems is considered a priority for the sustainable growth of marine and maritime sectors. To face this issue, the European MSP and MSFD directives (2014/89/EU; 2008/56/EC) strongly promote the adoption of an ecosystem-based approach, paying particular attention to the support of monitoring networks that use L-TER (long-term ecological research) observations and integrate multi-disciplinary data sets. Although not largely used in Europe yet, the Environmental Sensitivity Index (ESI), developed in 1979 by NOAA (and promoted by IMO in 2010), can be considered an excellent example of ecosystem-based approach to reduce the environmental consequences of an oil spill event in a coastal area. SUM is an ecosystem oriented cartographic tool specifically designed to support the sustainable management of the coastal areas, such as the selection of the best sites for the introduction of new uses or the identification of the coastal areas subjected to potential impacts. It also enables a rapid evaluation of the benefits produced by marine areas as well as of their anthropogenic disturbance. SUM integrates C-CEMS dataset, geomorphological and ecological features and knowledge on the coastal and maritime space uses. The SUM appliance allowed to obtain relevant operational results in the Civitavecchia coastal area (Latium, Italy), characterized by high variability of marine and coastal environments, historical heritage and affected by the presence of a big harbour, relevant industrial infrastructures, and touristic features. In particular, the valuation of marine ecosystem services based on

    Anaerobic digestion of corn ethanol thin stillage was tested at thermophilic temperature (55 degrees C) with two completely stirred tank reactors. The thin stillage wastestream was organically concentrated with 100 g/L total chemical oxygen demand and 60 g/L volatiles solids and a low pH of approximately 4.0. Steady-state was achieved at 30-, 20-, and 15-day hydraulic retention times (HRTs) and digester failure at a 12-day HRT. Significant reduction of volatile solids was achieved, with a maximum reduction (89.8%) at the 20-day HRT. Methane yield ranged from 0.6 to 0.7 L methane/g volatile solids removed during steady-state operation. Effluent volatile fatty acids below 200 mg/L as acetic acid were achieved at 20- and 30-day HRTs. Ultrasonic pretreatment was used for one digester, although no significant improvement was observed. Ethanol plant natural gas consumption could be reduced 43 to 59% with the methane produced, while saving an estimated $7 to $17 million ($10 million likely) for a facility producing 360 million L ethanol/y.

    In the present work, bismuth oxychloride nanoparticles-a light harvesting semiconductor photocatalyst-were synthesized by a facile hydrolysis route, with sodium bismuthate and hydroxylammonium chloride as the precursor materials. The as-synthesized semiconductor photocatalysts were characterized using X-ray diffraction analysis, Fourier transform infra-red spectroscopy, Raman spectroscopy, Field emission scanning electron microscopy, X-ray photoelectron spectroscopy and Photoluminescence spectroscopy techniques. The crystal structure, morphology, composition, and optical properties of these facile synthesized bismuth oxychloride nanoparticles (BiOCl NPs) were compared to those of traditional bismuth oxychloride. In addition, the photocatalytic performance of facile-synthesized BiOCl NPs and traditional BiOCl, as applied to the removal of hazardous organic dyes under visible light illumination, is thoroughly investigated. Our results reveal that facile-synthesized BiOCl NPs display strong UV-Vis light adsorption, improved charge carrier mobility and an inhibited rate of charge carrier recombination, when compared to traditional BiOCl. These enhancements result in an improved photocatalytic degradation rate of hazardous organic dyes under UV-Vis irradiance. For instance, the facile-synthesized BiOCl NPs attained 100% degradation of methylene blue and methyl orange dyes in approximately 30 mins under UV-Vis irradiation, against 55% degradation for traditional BiOCl under similar experimental conditions.

    Hanford's missions are to safely clean-up and manage the site's legacy wastes, and to develop and deploy science and technology. Through these missions Hanford will contribute to economic diversification of the region. Hanford's environmental management or clean-up mission is to protect the health and safety of the public, workers, and the environment; control hazardous materials; and utilize the assets (people, infrastructure, and site) for other missions. Hanford's science and technology mission is to develop and deploy science and technology in the service of the nation including stewardship of the Hanford Site. Pollution Prevention is a key to the success of these missions by reducing the amount of waste to be managed and identifying/implementing cost effective waste reduction projects. Hanford's original mission, the production of nuclear materials for the nation's defense programs, lasted more than 40 years, and like most manufacturing operations, Hanford's operations generated large quantities of waste and pollution. However, the by-products from Hanford operations pose unique problems like radiation hazards, vast volumes of contaminated water and soil, and many contaminated structures including reactors, chemical plants and evaporation ponds. The clean-up activity is an immense and challenging undertaking. Including characterization and decommissioning of 149 single shell storage tanks, treating 28 double shell tanks, safely disposing of over 2,100 metric tons of spent nuclear fuel stored on site, removing numerous structures, and dealing with significant solid waste, ground water, and land restoration issues.

    Full Text Available Economic Growth in Japan after World War II was very remarkable and products from its manufacturing industry were widely accepted in the world market after productivity and quality of them were tremendously improved. On the other hand, Japan soon found itself in severe environmental deterioration, due to not being paid any attention to environment. However, that pollution from industry was removed rather promptly with help of quality control and everyone’s participation. Japanese economic growth depends much on the quality of products, which was improved initially by what was known by Statistical Quality Control (SQC, widely used in the U.S.A. Later on SQC was transformed to Total Quality Control (TQC with small group activities named QC Circles by Japanese and with some modifications and/or from different approaches, Total Quality Management (TQM, Total Productive Maintenance (TPM, KAIZEN (improvement and so on were created. These approaches were introduced and widely used among industries and other sectors in Japan as well as in other countries of the world. The basic philosophy which leads these approaches to success was everyone’s participation and continuous efforts for improvement. The aim of these methods were at first to improve quality and productivity, but emission of hazardous material was reduced quickly and environmental circumstances inside and outside of manufacturing sites were drastically improved as well by these activities. As the result, most of Japanese products are environment-friendly from manufacturing origin and have excellent Quality at the same time. In this paper, the philosophies of these TQC, TPM etc. and how they had effectively worked for pollution prevention and environment-improvement will be discussed with supporting result data.

    A durable protected silver coating was designed and fabricated for possible use on flashlamp reflectors in the National Ignition Facility (NIF) to avoid tarnishing under corrosive conditions and intense visible light (10 J/cm{sup 2}, 360 {micro}s). This coating provides a valuable alternative for mirror coatings where high reflectance and durability are important requirements. This paper describes a protected silver coating having high reflectance from 400 mn to 10,000 mu. The specular reflectance is between 95% and 98% in the visible region and 98% or better in the infrared region.

  1. Transferring the Integrated Pollution Prevention and Control (IPPC Approach and Best Available Techniques (BAT Concepts to Egypt, Tunisia and Morocco

    Full Text Available The principles introduced by the Directive Concerning Integrated Pollution Prevention and Control (IPPC (currently known as the Industrial Emissions Directive (2010/75/EU are innovative and have raised interests in the framework of the literature debate on environmental regulation. Many articles describe and analyze the application of the Directive in European countries, but only a few articles focus on how the interest for the Directive’s principles, including the integrated approach, have reached countries outside the European Union. This paper aims to contribute to this topic, describing the experience of the authors in carrying out an EU-funded project on transferring the IPPC approach and Best Available Techniques (BAT concepts to three Arab countries, i.e., Egypt, Morocco and Tunisia. The paper presents the experience referring to two sectors falling within the scope of the IPPC Directive: the textile and dairy sector. The objectives, methodologies, activities and experiences are described and can be used and valorized to integrate the IPPC approach and BAT concepts in the current environmental legislation of the three countries.

    The purpose of this study was to estimate the gap between the available and the ideal supply of human resources (physicians, nurses, and health promoters) to deliver the guaranteed package of prevention and health promotion services at urban and rural primary care facilities in Mexico. We conducted a cross-sectional observational study using a convenience sample. We selected 20 primary health facilities in urban and rural areas in 10 states of Mexico. We calculated the available and the ideal supply of human resources in these facilities using estimates of time available, used, and required to deliver health prevention and promotion services. We performed descriptive statistics and bivariate hypothesis testing using Wilcoxon and Friedman tests. Finally, we conducted a sensitivity analysis to test whether the non-normal distribution of our time variables biased estimation of available and ideal supply of human resources. The comparison between available and ideal supply for urban and rural primary health care facilities reveals a low supply of physicians. On average, primary health care facilities are lacking five physicians when they were estimated with time used and nine if they were estimated with time required (P facilities. There is a shortage of health promoters in urban primary health facilities (P facilities.

    Mayo Clinic has been involved in an ongoing effort to prevent the diversion of controlled substances from the workplace and to rapidly identify and respond when such diversion is detected. These efforts have found that diversion of controlled substances is not uncommon and can result in substantial risk not only to the individual who is diverting the drugs but also to patients, co-workers, and employers. We believe that all health care facilities should have systems in place to deter controlled substance diversion and to promptly identify diversion and intervene when it is occurring. Such systems are multifaceted and require close cooperation between multiple stakeholders including, but not limited to, departments of pharmacy, safety and security, anesthesiology, nursing, legal counsel, and human resources. Ideally, there should be a broad-based appreciation of the dangers that diversion creates not only for patients but also for all employees of health care facilities, because diversion can occur at any point along a long supply chain. All health care workers must be vigilant for signs of possible diversion and must be aware of how to engage a preexisting group with expertise in investigating possible diversions. In addition, clear policies and procedures should be in place for dealing with such investigations and for managing the many possible outcomes of a confirmed diversion. This article provides an overview of the multiple types of risk that result from drug diversion from health care facilities. Further, we describe a system developed at Mayo Clinic for evaluating episodes of potential drug diversion and for taking action once diversion is confirmed.

    Hammond, Wesley; Thurston, Marland; Hood, Christopher

    1995-01-01

    The Titan 4 Space Launch Vehicle Program is one of many major weapon system programs that have modified acquisition plans and operational procedures to meet new, stringent environmental rules and regulations. The Environmental Protection Agency (EPA) and the Department of Defense (DOD) mandate to reduce the use of ozone depleting chemicals (ODC's) is just one of the regulatory changes that has affected the program. In the last few years, public environmental awareness, coupled with stricter environmental regulations, has created the need for DOD to produce environmental life-cycle cost estimates (ELCCE) for every major weapon system acquisition program. The environmental impact of the weapon system must be assessed and budgeted, considering all costs, from cradle to grave. The Office of the Secretary of Defense (OSD) has proposed that organizations consider Conservation, Cleanup, Compliance and Pollution Prevention (C(sup 3)P(sup 2)) issues associated with each acquisition program to assess life-cycle impacts and costs. The Air Force selected the Titan 4 system as the pilot program for estimating life-cycle environmental costs. The estimating task required participants to develop an ELCCE methodology, collect data to test the methodology and produce a credible cost estimate within the DOD C(sup 3)P(sup 2) definition. The estimating methodology included using the Program Office weapon system description and work breakdown structure together with operational site and manufacturing plant visits to identify environmental cost drivers. The results of the Titan IV ELCCE process are discussed and expanded to demonstrate how they can be applied to satisfy any life-cycle environmental cost estimating requirement.

    Current research reports the synthesis of reduced graphene oxide (RGO)-TiO2 nanocomposite by in-situ redox method and graphene oxide by modified hummers method. The ratio of RGO and TiO2 in the composite was optimized to show best photocatalytic activity for the degradation of targeted pollutants. Optimized (1:10) RGO-TiO2 nanocomposite was characterized by various techniques viz. X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA), Brunauer-Emmett-Teller surface area (BET), Raman and diffuse reflectance spectroscopy (DRS) technique confirming successful formation of nanocomposite. XRD results confirm the presence of anatase phase in RGO-TiO2. Uniform dispersion of TiO2 nanoparticles on RGO could be seen from TEM images. The obtained results of (1:10) RGO-TiO2 showed five-fold and two-fold enhancement for the visible light and UV light, respectively, for the photocatalytic mineralization of methylene blue dye as compared to commercial Aeroxide P25 TiO2. The excellent photocatalytic mineralization activity of (1:10) RGO-TiO2 could be attributed to the enhanced surface area of composite as well as to its good electron sink capability. (1:10) RGO-TiO2 could be recycled easily and was found to be equally efficient even after the fourth cycle for the photocatalytic mineralization of methylene blue dye. The non-selectivity of synthesized composite was checked by the mineralization studies of oxalic acid.

    This study focused on the synthesis of α-MoO3/rGO (rGO, reduced graphene oxide). One-dimensional nanohybrids under mild conditions and a low temperature wet chemical route produced highly pure single-crystalline orthorhombic α-MoO3 on GO sheets. Four nanohybrids, labeled as GMO-0, GMO-1, GMO-2 and GMO-3, were synthesized with different mass chargings of GO (0 mg, 40 mg, 60 mg and 100 mg, respectively). The photocatalytic performance for reduction of organic pollutants was analyzed. The presence of different amounts of GO in the prepared metal oxide hybrids altered the performance of the material as elaborated by the Brunauer-Emmett-Teller surface area, UV-visible diffuse reflectance spectra and the resulting reduction of organic dyes depicted by photocatalytic experiments. GO as a support material and active co-catalyst decreased the band gap of α-MoO3 (2.82 eV) to lower values (2.51 eV), rendering the prepared hybrids usable for visible-light-induced photocatalysis. The large specific surface area (72 m2 g-1) of the mesoporous α-MoO3/rGO nanohybrid made it an efficient photocatalyst for the elimination of azo dyes. Very fast reduction (100%) of Rhodamine B was observed in a few minutes, while Congo Red was degraded by 76% in 10 min, leading to the formation of stable intermediates that were completely neutralized in 12-14 h under light irradiation. The amount of GO loaded in the samples was limited to a point to achieve better results. After that, increasing the amount of GO decreased the extent of degradation due to the presence of a higher electron acceptor. Photocatalytic experiments revealed the synergistic effect, high selectivity of the prepared nanohybrids and degradation of azo dyes. The kinetics of the degradation reaction were studied and found to follow a pseudo first-order reaction.

    Nanostructured carbon-based materials, such as carbon nanotube arrays have shown respectable removal ability for heavy metal ions and organic dyes in aqueous solution. Although the carbon-based materials exhibited excellent removal ability, the separation of them from the aqueous solution is difficult and time-consuming. Here we demonstrated a novel and facile route for the large-scale fabrication of Fe3O4@C hollow nanospheres, with using ferrocene as a single reagent and SiO2 as a template. The as-prepared Fe3O4@C hollow nanospheres exhibited adsorption ability for heavy metal ions and organic dyes from aqueous solution, and can be easily separated by an external magnet. When the as-prepared Fe3O4@C hollow nanospheres were mixed with the aqueous solution of Hg2+ within 15 min, the removal efficiency was 90.3%. The as-prepared Fe3O4@C hollow nanospheres were also exhibited a high adsorption capacity (100%) as the adsorbent for methylene blue (MB). In addition, the as-prepared Fe3O4@C hollow nanospheres can be used as the recyclable sorbent for water treatment via a simple magnetic separation.

    OBJECTIVE To observe patient care across hemodialysis facilities enrolled in the National Opportunity to Improve Infection Control in ESRD (end-stage renal disease) (NOTICE) project in order to evaluate adherence to evidence-based practices aimed at prevention of infection. SETTING AND PARTICIPANTS Thirty-four hemodialysis facilities were randomly selected from among 772 facilities in 4 end-stage renal disease participating networks. Facility selection was stratified on dialysis organization affiliation, size, socioeconomic status, and urban/rural status. MEASUREMENTS Trained infection control evaluators used an infection control worksheet to observe 73 distinct infection control practices at the hemodialysis facilities, from October 1, 2011, through January 31, 2012. RESULTS There was considerable variation in infection control practices across enrolled facilities. Overall adherence to recommended practices was 68% (range, 45%-92%) across all facilities. Overall adherence to expected hand hygiene practice was 72% (range, 10%-100%). Compliance to hand hygiene before and after procedures was high; however, during procedures hand hygiene compliance averaged 58%. Use of chlorhexidine as the specific agent for exit site care was 19% overall but varied from 0% to 35% by facility type. The 8 checklists varied in the frequency of perfect performance from 0% for meeting every item on the checklist for disinfection practices to 22% on the arteriovenous access practices at initiation. CONCLUSIONS Our findings suggest that there are many areas for improvement in hand hygiene and other infection prevention practices in end-stage renal disease. These NOTICE project findings will help inform the development of a larger quality improvement initiative at dialysis facilities.

    It was intended to confirm, based on various problems surrounding oil flow-out accidents, that oil fences whose use is first considered when an oil flow-out accident occurs cause oil leakage due to oil pass-through phenomenon as the largest defect in performance of oil fences. Therefore, oil fence performance was analyzed by using a simulation. Furthermore, several types of diffusion prevention and avoidance measures, and combinations thereof were evaluated by using multi-criteria analysis. It was also elucidated how recognitions on the importance of methods to prevent oil pollution differ depending on standpoints. Difference in oil flow-out prevention performance of oil fences due to variation in tidal currents was made clear by combining a diffusion simulation using the finite element method with the prevention performance of oil fences relative to the tidal currents. In areas with no good hydrographic conditions where pollution spreads rapidly, it is necessary to suppress oil diffusion by extending oil fences double or triple, and using gelling agents. 4 refs., 8 figs.

    Micronutrient malnutrition is widespread and constitutes one of the main nutritional problems worldwide. Vitamins, amino acids, carbohydrates and Ca-phosphate (CaP) minerals are important to human health and disease prevention. Herein we developed a simple wet-chemical method to prepare multinary nutrients-containing CaP nanomaterials in diluted apple, orange, and grape juices. The scanning electron microscopy observation shows that these nanomaterials are short plate-like CaP nanocrystals of 500 nm in length. The X-ray photoelectron spectroscopy, nitrogen adsorption, thermogravimetric analyses confirm the different specific surface area and organic nutrient contents. The Fourier transform infrared and X-ray diffraction analyses indicate there exist similar organic groups (i.e., COO-, HN-CO) but different CaP species in the precipitates. The dissolution test in vitro simulated stomach juice pH condition indicates that these inorganic-organic nanohybrid materials are multidoped by micronutrients (such as Zn, Sr, Mg, K, vitamin c) and can be readily dissolved in the weak acidic aqueous solutions. This highly efficient utilization of fruit juice to produce CaP-based micronutrient composites may minimize the adverse side effect, so that the nanomaterials are promising as functional food/drink additives. Thus, this novel approach is environmentally and biologically friendly to produce edible nutrients while production cost is attained.

    In arid and semi-arid Mediterranean coastal areas, metals and metalloids (MM) pollution coming from unreclaimed brownfields has increased the negative environmental stresses leading to ecosystems degradations as soil erosion and losses of organic matter and biodiversity. On these sites, maintaining or restoring a local vegetation cover is considered as a key step to stop the degradation cycle. Furthermore, in a context of high pollution occurring in natural areas, phytoremediation is considered as an attractive alternative to conventional soil remediation techniques, the first reducing pollution transfers, improving the soil quality. In protected or natural areas, it is also important to perceive then design phytoremediation as a way to assist ecosystems recovery, using the restoration ecology concepts. However, only few works in the literature deal with the potential use of native Mediterranean plant species for phytoremediation. On the South-East coast of Marseille (France), the activity of the former smelting factory of l'Escalette, ceased since 1925. However, its brownfield is still a source of pollution by trace metals and metalloids for abiotic and biotic components of the surrounding massif. This massif hosts a rich biodiversity with rare and protected plant species despite the metallic pollution and this area has been included in the recently created first peri-urban French National Park of Calanques. In this context, an integrated research project is being conducted with local actors and stakeholders, from the selection of native plant species, assessment and optimization of phytostabilization capacities of selected species, to the development of ecological engineering techniques well adapted to local constraints and phytostabilization field trials. The first part of this study has been conducted on two areas, corresponding to different pollution pattern, plant communities and environmental drivers: a halophytic area, characterized by typical coastal

    In order to cope with heavy haze pollution in China, the Air Pollution Prevention and Control Action Plan including phased goals of the fine particulate matter (PM2.5) was issued in 2013. In this study, China's emission inventories in the baseline 2012 and the future scenarios of 2017 and 2020 have been developed based on this Action Plan. Beijing-Tianjin-Hebei (Jing-Jin-Ji) region, one of the most polluted regions in China, was taken as a case to assess the impact of phased emission control measures on PM2.5 concentration reduction using WRF-CMAQ model system. With the implementation of the Action Plan, the emissions of sulfur dioxide (SO2), nitrogen oxides (NOX), PM2.5, non-methane volatile organic compound (NMVOC), and ammonia (NH3) in 2017 will decrease by36%, 31%, 30%,12%, and -10% from the 2012 levels in Jing-Jin-Ji, respectively. In 2020, the emissions of SO2, NOX, PM2.5, NMVOC, and NH3 will decrease by 40%, 44%, 40%, 22%, and -3% from the 2012 levels in Jing-Jin-Ji, respectively. Consequently, the ambient annual PM2.5 concentration under the scenarios of 2017 and 2020 will be 28.3% and 37.8% lower than those in 2012, respectively. The Action Plan provided an effective approach to alleviate PM2.5 pollution level in Jing-Jin-Ji region. However, emission control of NMVOC and NH3 should be paid more attention and be strengthened in future. Meanwhile, emission control of NOx, SO2, NH3 and NMVOC synergistically are highly needed in the future because multiple pollutants impact on PM2.5 and O3 concentrations nonlinearly.

    Full Text Available In recent years, air pollution has become a major worldwide concern. Air pollutants can affect metabolic activity, impede healthy development, and exhibit carcinogenic and toxic properties in humans. Over the past two decades, the use of microbes to remove pollutants from contaminated air streams has become a widely accepted and efficient alternative to the classical physical and chemical treatment technologies. Air Pollution Prevention and Control: Bioreactors and Bioenergy focusses on these biotechnological alternatives looking at both the optimization of bioreactors and the development of cleaner biofuels.

    The aim of this research is to discuss the effectiveness of CLC/IOPC (Civil Liability Convention) liability regime in the field of oil pollution prevention. This study is mainly carried out from a law and economics perspective, although reference is also made to the economic analysis of international environmental agreements. The first two chapters explore the deterrent potential of the international regime in terms of oil spill prevention, from a theoretical and empirical perspective. The analysis of the effectiveness of the regime as such consists in, on the one hand, considering the ability of the international regime to compensate the entire social costs of oil spills (chapter 3) and, on the other hand, to examine the incentives given to operators in maritime oil transport to prevent accidental pollution (chapters 4 and 5). Sixth chapter considers the impacts of the voluntary nature of the international regime on its deterrent potential. The results obtained from this analysis enable to identify several mechanisms by which the deterrent effect of the existing regime could be increased. However, the overall effectiveness of the international regime appears to be limited by several factors that can not be corrected by means of a modification of the CLC and IOPC conventions. (author)

    This New Source Review'' has been submitted by the US Department of Energy-Richland Operations Office (PO Box 550, Richland, Washington 99352), pursuant to WAC 173-403-050 and in compliance with the Department of Ecology Guide to Processing A Prevention Of Significant Deterioration (PSD) Permit'' for three new sources of radionuclide emissions at the Hanford Site in Washington State. The three new sources, the Fueled Clad Fabrication System (FCFS), the Radioisotope Power Systems Facility (RPSF), and the Fuel Assembly Area (FAA), will be located in one facility, the Fuels and Materials Examination Facility (FMEF) of the 400 Area. The FMEF was originally designed to provide for post-irradiation examination and fabrication of breeder reactor fuels. These FMEF missions were cancelled before the introduction of any fuel materials or any irradiated material. The current plans are to use the facility to fabricate power supplies for use in space applications and to produce Fast Flux Test Facility (FFTF) fuel and target assemblies. The FCFS and the RPSF will produce materials and assemblies for application in space. The FAA project will produce FFTF fuel and target assemblies. The FCFS and the RPSF will share the same building, stack, and, in certain cases, the same floor space. Given this relationship, these systems will be dealt with separately to the extent possible. The FAA is a comparatively independent operation though it will share the FMEF complex.

    Under the influence of the dual structure of urban and rural, there are significant differences between urban and rural environmental protection in our country ,which resulted in the worsening of rural environment, especially garbage pollution. The rural garbage pollution has badly hurt farmers' environmental right, which has become the most challenging environmental issue in the process of new rural construction and ecological civilization construction in China. From a legislative design perspective, there are grave legislative defects in the prevention of rural garbage pollution, including the defect of legislative guidelines, the defect of legislative system and the defect of legislative content. Therefore, as guided by the environmental justice theory, Chinese legislation should make a further reflection for the prevention of rural garbage pollution in legislative philosophy, legislative model, legislative process, the construction of legal system and so on.%受城乡二元结构影响,我国城乡环境保护存在重大差异,由此导致农村环境不断恶化,其中垃圾污染尤为突出。农村垃圾污染已严重损害了农民环境权利,成为我国新农村建设和生态文明建设过程中亟需解决的环境问题。从立法角度看,我国农村垃圾污染防治在立法指导思想、立法体系以及立法内容等方面都存在严重的立法缺陷。因此,在环境正义理论的指导下,我国立法应该从立法理念、立法模式、立法程序和法律制度等方面对农村垃圾污染防治作进一步的思考。

  19. Governing change: land-use change and the prevention of nonpoint source pollution in the north coastal basin of California.

    2013-01-01

    Many rural areas in the United States and throughout much of the postindustrial world are undergoing significant ecological, socioeconomic, and political transformations. The migration of urban and suburban dwellers into rural areas has led to the subdivision of large tracts of land into smaller parcels, which can complicate efforts to govern human-environmental problems. Non-point source (NPS) pollution from private rural lands is a particularly pressing human-environmental challenge that may be aggravated by changing land tenure. In this article, I report on a study of the governance and management of sediment (a common NPS pollutant) in the North Coastal basin of California, a region undergoing a transition from traditional extractive and agricultural land uses to rural residential and other alternative land uses. I focus on the differences in the governance and management across private timber, ranch, residential, vacation, and other lands in the region. I find that (1) the stringency and strength of sediment regulations differ by land use, (2) nonregulatory programs tend to target working landscapes, and (3) rural residential landowners have less knowledge of sediment control and report using fewer sediment-control techniques than landowners using their land for timber production or ranching. I conclude with an exploration of the consequences of these differences on an evolving rural landscape.

    Full Text Available Background: When new guidelines for existing programmes are introduced, it is often the clinicians tasked with the execution of the guidelines who bear the brunt of the changes. Frequently their opinions are not sought. In this study, the researcher interviewed registered nurses working in the field of the prevention of mother-to-child transmission (PMTCT of human immunodeficiency virus (HIV to gain an understanding of their perspectives on the changes introduced to the guidelines. The guideline changes in 2014 were to move from the World Health Organization (WHO Option B to Option B + which prescribes lifelong antiretroviral therapy (ART for all HIV-positive pregnant women regardless of CD4 cell count.Objective: To determine what the registered nurses’ perspectives are on the PMTCT programme as implemented at four PHC facilities in the Limpopo Province.Method: For this qualitative investigation, a descriptive research design was implemented. The data were collected during semi-structured interviews with nurses from four primary healthcare facilities in the Limpopo Province of South Africa. Data were analysed using thematic analysis.Results: Challenges preventing effective implementation (e.g. increased workloads, viz. staff shortages; poor planning of training; equipment and medication shortages and long lead times; poor patient education were identified.Conclusion: In spite of the successes of the PMTCT programme, considerable challenges still prevail; lack of patient education, poor facilities management and staff shortages could potentially influence the implementation of the PMTCT guidelines negatively.

    Determining if a transfer of a skilled nursing facility (SNF) patient/resident to an acute hospital is potentially avoidable or preventable is challenging. Most previous research on potentially avoidable or preventable hospitalizations is based on diagnoses without in-depth root cause analysis (RCA), and few studies have examined SNF staff perspective on preventability of transfers. To examine factors associated with hospital transfers rated as potentially preventable versus nonpreventable by SNF staff. Trained staff from SNFs enrolled in a randomized controlled clinical trial of the INTERACT (Interventions to Reduce Acute Care Transfers) quality improvement program performed retrospective RCAs on hospital transfers during a 12-month implementation period. SNFs from across the United States. Sixty-four of 88 SNFs randomized to the intervention group submitted RCAs with a rating of whether the transfer was determined to be potentially preventable or nonpreventable. SNFs were implementing the INTERACT Quality Improvement (QI) program. Data were abstracted from the INTERACT QI tool, a structured, retrospective RCA on hospital transfers. A total of 4527 RCAs with a rating of preventability were submitted during the 12-month implementation period, of which 1044 (23%) were rated as potentially preventable by SNF staff. In unadjusted univariate analyses, factors associated with ratings of potentially preventable included acute changes in condition of fever, decreased food or fluid intake, functional decline, shortness of breath, and new urinary incontinence; other factors included the clinician, resident, and/or family insisting on the transfer, transfers that occurred fewer than 30 days from SNF admission and that occurred on weekends, transfers ordered by a covering physician (as opposed to the primary physician), and transfers that resulted in an emergency department (ED) visit with return to the SNF. Factors associated with ratings of nonpreventable included on

    2016-05-01

    Full Text Available One of the fundamental challenges to implementing successful prevention of mother-tochild transmission (PMTCT programs in Nigeria is the uptake of PMTCT services at health facilities. Several issues usually discourage many pregnant women from receiving antenatal care services at designated health facilities within their communities. The CRS Nigeria PMTCT Project funded by the Global Fund in its Round 9 Phase 1 in Nigeria, sought to increase demand for HIV counseling and testing services for pregnant women at 25 supported primary health centers (PHCs in Kaduna State, North-West Nigeria by integrating traditional birth attendants (TBAs across the communities where the PHCs were located into the project. Community dialogues were held with the TBAs, community leaders and women groups. These dialogues focused on modes of mother to child transmission of HIV and the need for TBAs to refer their clients to PHCs for testing. Subsequently, data on number of pregnant women who were counseled, tested and received results was collected on a monthly basis from the 25 facilities using the national HIV/AIDS tools. Prior to this integration, the average number of pregnant women that were counseled, tested and received results was 200 pregnant women across all the 25 health facilities monthly. After the integration of TBAs into the program, the number of pregnant women that were counseled, tested and received results kept increasing month after month up to an average of 1500 pregnant women per month across the 25 health facilities. TBAs can thus play a key role in improving service uptake and utilization for pregnant women at primary health centers in the community – especially in the context of HIV/AIDS. They thus need to be integrated, rather than alienated, from primary healthcare service delivery.

    The release of pharmaceuticals and personal care products (PPCPs) into the environment has been held up as a potential threat to ecosystem and human health. Using a custom-designed survey of residents living in Xiamen, China, this paper examines individuals' disposal practices, awareness of the environmental impact of PPCPs, and willingness to pay for measures aimed at reducing the likelihood of PPCPs being released into the environment. The vast majority of respondents report that they dispose of PPCPs through the thrash. The results of a contingent valuation experiment suggest a substantial willingness to pay (WTP) for policy measures aimed at reducing PPCP pollution. Income as well as subjective perceptions relating to overall financial health, expenditure on PPCPs, and overall concern with environmental issues emerged as significant predictors of respondents' WTP. Our results should be of interest to policymakers looking for ways to mitigate the introduction of PPCPs in the environment. Integr Environ Assess Manag 2016;12:793-800. © 2015 SETAC. © 2015 SETAC.

    Objectives To investigate whether the preventive use of cranberry capsules in long-term care facility (LTCF) residents is cost-effective depending on urinary tract infection (UTI) risk. Design Economic evaluation with a randomized controlled trial. Setting Long-term care facilities. Participants LTCF residents (N = 928, 703 female, median age 84), stratified according to UTI risk. Measurements UTI incidence (clinically or strictly defined), survival, quality of life, quality-adjusted life years (QALYs), and costs. Results In the weeks after a clinical UTI, participants showed a significant but moderate deterioration in quality of life, survival, care dependency, and costs. In high-UTI-risk participants, cranberry costs were estimated at €439 per year (1.00 euro = 1.37 U.S. dollar), which is €3,800 per prevented clinically defined UTI (95% confidence interval = €1,300–infinity). Using the strict UTI definition, the use of cranberry increased costs without preventing UTIs. Taking cranberry capsules had a 22% probability of being cost-effective compared with placebo (at a willingness to pay of €40,000 per QALY). In low-UTI-risk participants, use of cranberry capsules was only 3% likely to be cost-effective. Conclusion In high-UTI-risk residents, taking cranberry capsules may be effective in preventing UTIs but is not likely to be cost-effective in the investigated dosage, frequency, and setting. In low-UTI-risk LTCF residents, taking cranberry capsules twice daily is neither effective nor cost-effective. PMID:25180379

    More than half the world's rainforest has been lost to agriculture since the Industrial Revolution. Among the most widespread tropical crops is oil palm (Elaeis guineensis): global production now exceeds 35 million tonnes per year. In Malaysia, for example, 13% of land area is now oil palm plantation, compared with 1% in 1974. There are enormous pressures to increase palm oil production for food, domestic products, and, especially, biofuels. Greater use of palm oil for biofuel production is predicated on the assumption that palm oil is an "environmentally friendly" fuel feedstock. Here we show, using measurements and models, that oil palm plantations in Malaysia directly emit more oxides of nitrogen and volatile organic compounds than rainforest. These compounds lead to the production of ground-level ozone (O(3)), an air pollutant that damages human health, plants, and materials, reduces crop productivity, and has effects on the Earth's climate. Our measurements show that, at present, O(3) concentrations do not differ significantly over rainforest and adjacent oil palm plantation landscapes. However, our model calculations predict that if concentrations of oxides of nitrogen in Borneo are allowed to reach those currently seen over rural North America and Europe, ground-level O(3) concentrations will reach 100 parts per billion (10(9)) volume (ppbv) and exceed levels known to be harmful to human health. Our study provides an early warning of the urgent need to develop policies that manage nitrogen emissions if the detrimental effects of palm oil production on air quality and climate are to be avoided.

  14. Nitrogen management is essential to prevent tropical oil palm plantations from causing ground-level ozone pollution

    More than half the world's rainforest has been lost to agriculture since the Industrial Revolution. Among the most widespread tropical crops is oil palm (Elaeis guineensis): global production now exceeds 35 million tonnes per year. In Malaysia, for example, 13% of land area is now oil palm plantation, compared with 1% in 1974. There are enormous pressures to increase palm oil production for food, domestic products, and, especially, biofuels. Greater use of palm oil for biofuel production is predicated on the assumption that palm oil is an ‘‘environmentally friendly'' fuel feedstock. Here we show, using measurements and models, that oil palm plantations in Malaysia directly emit more oxides of nitrogen and volatile organic compounds than rainforest. These compounds lead to the production of ground-level ozone (O3), an air pollutant that damages human health, plants, and materials, reduces crop productivity, and has effects on the Earth's climate. Our measurements show that, at present, O3 concentrations do not differ significantly over rainforest and adjacent oil palm plantation landscapes. However, our model calculations predict that if concentrations of oxides of nitrogen in Borneo are allowed to reach those currently seen over rural North America and Europe, ground-level O3 concentrations will reach 100 parts per billion (109) volume (ppbv) and exceed levels known to be harmful to human health. Our study provides an early warning of the urgent need to develop policies that manage nitrogen emissions if the detrimental effects of palm oil production on air quality and climate are to be avoided.

    Research was conducted to identify an ergonomics-based intervention model designed to factor in musculoskeletal disorder (MSD) prevention when library projects are being designed. The first stage of the research involved an a posteriori analysis of 10 recent redesign projects. The purpose of the analysis was to document perceptions about the attention given to MSD prevention measures over the course of a project on the part of 2 categories of employees: librarians responsible for such projects and personnel working in the libraries before and after changes. Subjects were interviewed in focus groups. Outcomes of the analysis can guide our ergonomic assessment of current situations and contribute to a better understanding of the way inclusion or improvement of prevention measures can support the workplace design process.

    Pesticides are important agricultural production materials. It is significant to prevent plant diseases and insect pest and promote agriculture, forestry, animal husbandry production, but the pesticide is a toxic substance, and has caused serious harm to the quality and safety of agricultural products, health of people and environmental resources. However, Chinese environmental legislation about pesticide is seriously lagging behind, the legislative level of current laws is low, the operability is poor, and managers are more, functions cross is more prevalent, illegal cost of pesticide contamination is less. Therefore it is necessary to develop a special pesticide pollution control act to improve the pesticide registration system, to implement the pesticide license system of sailing, to reform the supervision and management mechanism of pesticide pollution.%农药是重要的农业生产资料,对于防治病虫害,促进农、林、牧业生产意义重大,但农药又是一种有毒物质,已对农产品质量安全、人们身体健康以及环境资源造成严重危害.然而,我国现行的农药环保立法严重滞后,已有法律规范立法层级低,可操作性差,多头管理、职能交叉的现象较为普遍,农药污染的违法成本很低.因此有必要制定一部专门的农药污染防治法,完善农药登记制度,实施农药经营许可制度,改革农药污染监督管理机制.

    Effective implementation of infection prevention and control in healthcare facilities depends on training, awareness and compliance of healthcare workers. In Saudi Arabia recent significant hospital outbreaks, including Middle East Respiratory Syndrome Coronavirus (MERS-CoV), have resulted from lack of, or breakdown in, infection prevention and control procedures. This study was designed to assess attitudes to, and awareness of, infection prevention and control policies and guidelines among healthcare workers of different professions and institution types in Saudi Arabia. A questionnaire was administered to 607 healthcare workers including physicians (n=133), nurses (n=162), laboratory staff (n=233) and other staff (n=79) in government hospitals, private hospitals and poly clinics. Results were compared using Chi square analysis according to profession type, institution type, age group and nationality (Saudi or non-Saudi) to assess variability. Responses suggested that there are relatively high levels of uncertainty among healthcare workers across a range of infection prevention and control issues, including institution-specific issues, surveillance and reporting standards, and readiness and competence to implement policies and respond to outbreaks. There was evidence to suggest that staff in private hospitals and nurses were more confident than other staff types. Carelessness of healthcare workers was the top-cited factor contributing to causes of outbreaks (65.07% of total group), and hospital infrastructure and design was the top-cited factor contributing to spread of infection in the hospital (54.20%), followed closely by lack and shortage of staff (53.71%) and no infection control training program (51.73%). An electronic surveillance system was considered the most effective by staff (81.22%). We have identified areas of concern among healthcare workers in Saudi Arabia on infection prevention and control which vary between institutions and among different

    A clinical decision support system that guides nurse practitioners and other healthcare providers in secondary stroke prevention was developed by a multidisciplinary team with funding received from the Veterans Health Administration Office of Nursing Services. This article presents alpha-testing results obtained while using an integrated model for clinical decision support system development that emphasizes end-user perspectives throughout the development process. Before-after and descriptive methods were utilized to evaluate functionality and usability of the prototype among a sample of multidisciplinary clinicians. The predominant functionality feature of the tool is automated prompting and documentation of secondary stroke prevention guidelines in the electronic medical record. Documentation of guidelines was compared among multidisciplinary providers (N = 15) using test case scenarios and two documentation systems, standard versus the prototype. Usability was evaluated with an investigator-developed questionnaire and one open-ended question. The prototype prompted a significant increase (P < .05) in provider documentation for six of 11 guidelines as compared with baseline documentation while using the standard system. Of a possible 56 points, usability was scored high (mean, 48.9 [SD, 6.8]). These results support that guideline prompting has been successfully engineered to produce a usable and useful clinical decision support system for secondary stroke prevention.

    The development of Z-scheme heterojunction photocatalytic systems is a promising strategy to produce hydrogen and for pollutant degradation. In this study, the direct Z-scheme CdS/Bi4V2O11 photocatalysts were synthesized via a two-step solvothermal method. The photocatalytic properties of the samples were measured by ciprofloxacin (CIP), tetracycline (TC) and rhodamine B (RhB) degradation under visible light (λ > 420 nm). In addition, a probable reaction mechanism for organic pollutants over CdS/Bi4V2O11 photocatalysts was also proposed based on the analysis of electron spin resonance (ESR) and active species capture experiments. The enhanced photocatalytic activity of CdS/Bi4V2O11 photocatalysts was ascribed to the efficient electron transfer of direct Z-scheme CdS/Bi4V2O11 photocatalysts.

    Full Text Available Objectives: Investigate levels of retention at specified time periods along the prevention of mother-to-child transmission (PMTCT cascade among mother-infant pairs as well as individual- and facility-level factors associated with retention. Methods: A retrospective cohort of HIV-positive pregnant women and their infants attending five health centres from November 2010 to February 2012 in the Option B programme in Rwanda was established. Data were collected from several health registers and patient follow-up files. Additionally, informant interviews were conducted to ascertain health facility characteristics. Generalized estimating equation methods and modelling were utilized to estimate the number of mothers attending each antenatal care visit and assess factors associated with retention. Results: Data from 457 pregnant women and 462 infants were collected at five different health centres (three urban and two rural facilities. Retention at 30 days after registration and retention at 6 weeks, 3, 6, 9 and 12 months post-delivery were analyzed. Based on an analytical sample of 348, we found that 58% of women and 81% of infants were retained in care within the same health facility at 12 months post-delivery, respectively. However, for mother-infant paired mothers, retention at 12 months was 74% and 79% for their infants. Loss to facility occurred early, with 26% to 33% being lost within 30 days post-registration. In a multivariable model retention was associated with being married, adjusted relative risk (ARR: 1.26, (95% confidence intervals: 1.11, 1.43; antiretroviral therapy eligible, ARR: 1.39, (1.12, 1.73 and CD4 count per 50 mm3, ARR: 1.02, (1.01, 1.03. Conclusions: These findings demonstrate varying retention levels among mother-infant pairs along the PMTCT cascade in addition to potential determinants of retention to such programmes. Unmarried, apparently healthy, HIV-positive pregnant women need additional support for programme retention

The average weighted WPI forms the basis of weather type number, synoptic weather forecast allows you to define a subtype of the weather. This classification is used in the system of MWF in the resorts of Caucasian Mineral Waters (mountainous region of Northern Caucasus), making for the purpose of timely warnings of medical personnel of medical institutions to strengthen health surveillance and, if necessary, conduct prevention of MPR. MPR to changing weather conditions are most manifest in connection with resettlement of patients from their places of permanent residence to the unusual climatic conditions of the resort. In this regard, in order to enhance the spa rehabilitation of meteosensitive patients with coronary artery disease at PSRIC a physiological method was developed for early and routine prophylaxis of maladaptive pathological and, above all, MPR using the method of transcranial electric-pulse meso-diencephalic modulation by MDMK-4 apparatus with a frontooccipital location of the electrodes. Clinical manifestation of the MPR in adverse weather conditions in patients with coronary artery disease, hypertension with dysadaptation syndrome is characterized by frequent recurrences of angina, rhythm disorders, cerebral symptoms, vascular crisis, violations in the field of psycho-emotional area and other disorders. These meteopathies are eliminated with high efficiency using the MDMK-4 apparatus in individually selected modes at the planned rate of prophylaxis for 10 procedures. In order to urgent MPR prevention the procedures can be used situationally. The high preventive and curative effects of transcranial electric-pulse meso-diencephalic modulation of the MDMK-4 apparatus is shown by positive dynamics of the clinical status of patients, including data on the MPR test survey, the Kerdem vegetative index, rheoencephalography indicators, electrocardiography, neurovascular reactivity, Holter

    The primary objective of any Biopharmaceutical Product Changeover (PCO) program is to employ control strategies before, during, and after the manufacturing process, as well as from the beginning of the lifecycle approach for the equipment and validation, which will minimize the opportunity for cross- contamination when switching between products. Evaluation of the need for an Elastomer Change Out (ECO) should be considered as a segment of an overall changeover assessment. Lifecycle systems (e.g. Preventive Maintenance (PM), Cleanability Coupon Testing, Good Engineering Practices, etc.) and procedures should be in place and data should be generated demonstrating the soft parts do not harbor residues from the previous product campaign(s). The determination of whether or not to replace elastomers/soft parts should be made in the context of all of these systems along with the proper assessment of Risk. By understanding the actual value of ECO in terms of the overall PCO program, and the other systems and procedures that are in place that protect against cross contamination, the need for ECO for every product changeover is not necessary. The purpose of this paper is to review the practice of ECO at product changeover, evaluate the need for an ECO using a risk based approach, and provide rationale for justifying the reduction or elimination of ECO at product changeover.

Different divisions of water management facilities are carried out (to public and private ones, natural and artificial ones, etc., with determination of their legal relevance. Account is taken of the issue of protection from harmful effects of waters to such facilities, as well. The paper points also to rules on the water management facilities, from acts of planning, to individual administrative acts and measures for maintenance of required qualitative and quantitative condition of waters, depending on their purpose (general use or special, commercial use o waters. Albeit special rules on water management facilities exist, due to the natural interlocking between all the components of the environment (water, air and soil, a comprehensive approach is required. A reference is made to other basic principles of protection of water management facilities as well, such as the principle of prevention, principle of sustainable development and the principle "polluter pays". The last one represents the achievement of contemporary law, which deviates from the idea accepted in the second half of 20th century that supported the socialization of risk from harmful effects of waters.

    The objective of this project was to isolate and characterize thermophilic bacterial cultures that can be used for the selective removal of nitrogen, sulfur, and/or metals in the biorefining of petroleum. The project was completed on schedule and no major difficulties were encountered. Significant progress was made on multiple topics relevant to the development of a petroleum biorefining process capable of operating at thermophilic temperatures. New cultures capable of selectively cleaving C-N or C-S bonds in molecules relevant to petroleum were obtained, and the genes encoding the enzymes for these unique biochemical reactions were cloned and sequenced. Genetic tools were developed that enable the use of Thermus thermophilus as a host to express any gene of interest, and information was obtained regarding the optimum conditions for the growth of T. thermophilus. The development of a practical biorefining process still requires further research and the future research needs identified in this project include the development of new enzymes and pathways for the selective cleavage of C-N or C-S bonds that have higher specific activities, increased substrate range, and are capable of functioning at thermophilic temperatures. Additionally, there is a need for process engineering research to determine the maximum yield of biomass and cloned gene products that can be obtained in fed-batch cultures using T. thermophilus, and to determine the best configuration for a process employing biocatalysts to treat petroleum.

    Objectives To determine whether cranberry capsules prevent urinary tract infection (UTI) in long-term care facility (LTCF) residents. Design Double-blind randomized placebo-controlled multicenter trial. Setting Long-term care facilities (LTCFs). Participants LTCF residents (N = 928; 703 women, median age 84). Measurements Cranberry and placebo capsules were taken twice daily for 12 months. Participants were stratified according to UTI risk (risk factors included long-term catheterization, diabetes mellitus, ≥1 UTI in preceding year). Main outcomes were incidence of UTI according to a clinical definition and a strict definition. Results In participants with high UTI risk at baseline (n = 516), the incidence of clinically defined UTI was lower with cranberry capsules than with placebo (62.8 vs 84.8 per 100 person-years at risk, P = .04); the treatment effect was 0.74 (95% confidence interval (CI) = 0.57–0.97). For the strict definition, the treatment effect was 1.02 (95% CI = 0.68–1.55). No difference in UTI incidence between cranberry and placebo was found in participants with low UTI risk (n = 412). Conclusion In LTCF residents with high UTI risk at baseline, taking cranberry capsules twice daily reduces the incidence of clinically defined UTI, although it does not reduce the incidence of strictly defined UTI. No difference in incidence of UTI was found in residents with low UTI risk. PMID:25180378

    Non point source pollutants, such as pesticides and fertilizers derived from agricultural activities, are recognized as an important threat to environment and human health. To prevent the adverse effects of these agrochemicals it is necessary to provide growers and decision makers with easy-to-use information. Attempts have been made to put information on pesticides environmental and health effects into a formula that could summarize, in a single number, these effects. However a single number could be misleading because of the lack of information on chemical-physical parameters and the difficulty to evaluate the relative importance of various environmental and health effects. As an alternative it is here proposed an approach based on schedule containing information, for each pesticides, such as short and long term effects on human health, environmental fate and degradation time, capacity to bio accumulate, toxicity of degradation products. Using information in the schedule, decision makers could make more circumstantiate choices and could program the best agricultural actions under particular environmental circumstances with less impact on man and environment. [Italian] L'inquinamento diffuso derivante dall'uso dei fertilizzanti e dei pesticidi in agricoltura, rappresenta un rischio rilevante per l'ambiente e la salute umana.

    Full Text Available Background: Even though significant progress has been made in the roll-out and quality of the prevention of mother-to-child transmission of HIV (PMTCT services in South Africa, the quality of patient data recording remains a challenge. Objectives: To assess PMTCT data completeness and accuracy at primary healthcare level to district level in order to assist with the improvement of the PMTCT data recording. Methods: This is a retrospective record review study which involved collecting PMTCT data on indicators which was for the period of August 2009 to January 2010. We conducted baseline facility assessments which included 72 PMTCT sites in one health district, Nkangala. We assessed the data completeness and accuracy of the data values recorded on the seven PMTCT data elements. Results: Data were only complete for less than a quarter of the time for most of the antenatal indicators (0.5% – 44% and for the maternity indicators, data were only complete 11% of the time. Data inaccuracy was a result of recording of data values in the District Health Information System (DHIS which were not within 10% of the data values recorded in the case registers. The results show that data were missing from the case registers, monthly summary sheets and DHIS between 30% and 99% of the time and that data elements had values recorded in the DHIS which were > 10%. Conclusion: There is a need for ongoing training on data recording procedures at all levels. To maintain data quality, healthcare data must be appropriate, organised, timely, available, accurate and complete.

    2015-06-01

    Knowledge about the effects of oxygen concentration, nutrient availability and moisture content on removal of organic micro-pollutants during aerobic composting is at present very limited. Impact of oxygen concentration, readily available nitrogen content (NH4(+), NO3(-)), and moisture content on biological transformation of 15 key organic micro-pollutants during composting, was therefore investigated using bench-scale degradation experiments based on non-sterile compost samples, collected at full-scale composting facilities. In addition, the adequacy of bench-scale composting experiments for representing full-scale composting conditions, was investigated using micro-pollutant concentration measurements from both bench- and full-scale composting experiments. Results showed that lack of oxygen generally prevented transformation of organic micro-pollutants. Increasing readily available nitrogen content from about 50 mg N per 100 g compost to about 140 mg N per 100 g compost actually reduced micro-pollutant transformation, while changes in compost moisture content from 50% to 20% by weight, only had minor influence on micro-pollutant transformation. First-order micro-pollutant degradation rates for 13 organic micro-pollutants were calculated using data from both full- and bench-scale experiments. First-order degradation coefficients for both types of experiments were similar and ranged from 0.02 to 0.03 d(-1) on average, indicating that if a proper sampling strategy is employed, bench-scale experiments can be used to represent full-scale composting conditions.

    2015-01-01

    Agricultural decision-making to control nonpoint source (NPS) water pollution may not be efficiently implemented, if there is no appropriate cost-benefit analysis on agricultural management practices. This paper presents an interval-fuzzy linear programming (IFLP) model to deal with the trade-off between agricultural revenue, NPS pollution control, and alternative practices through land adjustment for Wuchuan catchment, a typical agricultural area in Jiulong River watershed, Fujian Province of China. From the results, the lower combination of practice 1, practice 2, practice 3, and practice 7 with the land area of 12.6, 5.2, 145.2, and 85.3 hm(2), respectively, could reduce NPS pollution load by 10%. The combination yields an income of 98,580 Chinese Yuan/a. If the pollution reduction is 15%, the higher combination need practice 1, practice 2, practice 3, practice 5, and practice 7 with the land area of 54.4, 23.6, 18.0, 6.3, and 85.3 hm(2), respectively. The income of this combination is 915,170 Chinese Yuan/a. The sensitivity analysis of IFLP indicates that the cost-effective practices are ranked as follows: practice 7 > practice 2 > practice 1 > practice 5 > practice 3 > practice 6 > practice 4. In addition, the uncertainties in the agriculture NPS pollution control system could be effectively quantified by the IFLP model. Furthermore, to accomplish a reasonable and applicable project of land-use adjustment, decision-makers could also integrate above solutions with their own experience and other information.

    Full Text Available As the accumulation of PCDDs/Fs in the natural environment poses a great threat, and the pollution of the environment with these highly toxic compounds from various emitters needs to be prevented, many countries have conducted an inventory of industrial sources and their emissions in order to obtain better insight into the share of particular sources in the total emission of PCDDs/Fs and to develop strategies to reduce these emissions.Metallurgical processes like sintering of iron ore, production of steel and non-ferrous and light metals from scrap material belong to a group of stationary PCDDs/Fs emitters and their share in the total PCDDs/Fs emission into the environment is very significant. The relative significance of particular metallurgical processes varies from country to country, depending on the nature of a particular process, installed capacities and annual output levels.As the modern approach to observing the environment includes preventive measures, as opposed to corrective post-event measures that were common practice in the past, the owners/operators of metallurgical processes are developing and introducing pollution monitoring and surveillance systems, based on which they take appropriate measures.One of the frequently applied measures is to build and implement the ISO 14001 environmental management system that very efficiently runs production processes along with maintenance of environmental protection on a daily basis. Since the adoption of the ISO 14001 environmental management system is a voluntary decision to be made by each organization, in 1996 the European Union adopted, for the purpose of environmental protection and pollution prevention, the Directive 96/61 EC or IPPC Directive on Integrated Pollution Prevention and Control (IPPC requiring from industrial installations, depending on their type and output level, to obtain environmental permits to run production processes using best available techniques, thus maintaining

    While bacterial sexually transmitted infections (STIs) are important cofactors for HIV transmission, STI control has received little attention in recent years. The aim of this study was to assess STI treatment and HIV testing referral practices among health providers in Kenya. In 2011 we assessed quality of case management for male urethritis at pharmacies, private clinics and government health facilities in coastal Kenya using simulated visits at pharmacies and interviews at pharmacies and health facilities. Quality was assessed using Ministry of Health guidelines. Twenty (77%) of 26 pharmacies, 20 (91%) of 22 private clinics and all four government facilities in the study area took part. The median (IQR) number of adult urethritis cases per week was 5 (2-10) at pharmacies, 3 (1-3) at private clinics and 5 (2-17) at government facilities. During simulated visits, 10% of pharmacies prescribed recommended antibiotics at recommended dosages and durations and, during interviews, 28% of pharmacies and 27% of health facilities prescribed recommended antibiotics at recommended dosages and durations. Most regimens were quinolone-based. HIV testing was recommended during 10% of simulated visits, 20% of pharmacy interviews and 25% of health facility interviews. In an area of high STI burden, most men with urethritis seek care at pharmacies and private clinics. Most providers do not comply with national guidelines and very few recommend HIV testing. In order to reduce the STI burden and mitigate HIV transmission, there is an urgent need for innovative dissemination of up-to-date guidelines and inclusion of all health providers in HIV/STI programmes.

    Currently, the world is facing challenges of maintaining food production growth while improving agricultural ecological environ-mental quality. The prevention and control of agricultural non-point source pollution, a key component of these challenges, is a systematic program which integrates many factors such as technology and its extension, relevant regulation and policies. In the project of UK-China Sustainable Agriculture Innovation Network, we undertook a comprehensive analysis of the prevention and control technology, technology extension systems and related policy measures of agricultural non-point source pollution in UK. We then proposed the promotion of preven-tion and control of agricultural non-point source pollution in China. Considering the current agricultural resources and environment counter-measures of“one control”(control over the total quantity of the agricultural water and agricultural water environment pollution),“two re-duction”(reduction in quantities of fertilizers and pesticides), and “three basic countermeasures”(resource utilization, recycling, and disharm treatment of livestock and poultry wastes, agricultural plastic films and crop straws), we suggested that in the near future source control and process prevention should be technical priorities. Optimzation and reduction of chemical fertilizer, combined use of chemical and organic fertilizers, land utilization management, agricultural sector adjustment and integration of crop production with animal husbandry should be the key technologies. The role of non-governmental technical service should be promoted. Government subsidies, ecological com-pensations and other forms of economic means could be used to encourage famers actively participate in the prevention and control of nitro-gen and phosphorus losses and pollution in soil and water systems. Related technical documents and regulations should be more specific, clear, and practical. Collection, transmission and analysis of

    Full Text Available Air pollution still exceeds safe limits worldwide, particularly in big metropolitans, despite regular monitoring facilities and measures taken. It is usually originated from industrial activities, fossil fuel use in domestic settings and vehicle exhaust emission. Although there is a decrease in air pollution in big cities of Turkey due to use of natural gas, it is still a serious health concern. In Diyarbakır, because of a rapid increase in its population recently, wrong urbanisation and a relative increase in industrialisation, air pollution leads to dangerous levels, particularly in the winter. Epidemiological studies from all over the world, and Turkey have reported a close relation between air pollution and respiratory morbidity and mortality. Studies investigating the mechanisms underlying respiratory effects of air pollution demonstrated that pollutants lead to increased respiratory symptoms, decreased respiratory function and induce inflammatory changes in airways. In vitro studies have shown that air pollutants exert their effects by causing cellular injury directly, and by activating intracellular oxidative pathways indirectly. The attempts to reduce air pollution levels have been implemented in Turkey and worldwide. In order to solve the problem in Diyarbakır, several measures such as prevention the use of out standardized fuel, use of reliable burning techniques, and a close car emission monitoring system need to be implemented.

The urban water-runoff is the second pollution source which can bring serious impact on the urban water quality and therefore it has been studied since 1970s in the western countries though little attention has been paid to in our country. From the point of view of the environmental protection, it can be said that a Jot of various pollutants has been caused by the road runoff, such as the paniculate matter, the organic nutrients, heavy metal ingredients and so on, among which the particulate matters should be regarded as the chief carriers for other pollutants. And, it is for this reason, the Environmental Protection Agency of the United States, short for USEPA, has reen-forced its management policy and practical measures in controlling the runoff pollution since 1976 with nonpoint source pollution controlled successfully. And, consequently, great reduction of the corresponding resource pollution has been achieved, which has in turn promoted the establishment of effective economic

  12. Comparative advantage strategy for rapid pollution mitigation in China.

    2013-09-01

    Due to its sheer size and growth trend, no other country is facing more daunting challenges than China in reducing its pollutant emissions. A critical but inadequately addressed question is how rapidly China could feasibly achieve such mitigation. The stake is high not only about how much worse China's environmental quality could become but also about how the world can prevent catastrophic climate change. Through examining sulfur dioxide (SO2) mitigation in coal-fired power plants and wind energy development for carbon dioxide (CO2) mitigation, this article proposes a comparative advantage strategy for overcoming high barriers to fast pollution mitigation. On the demand side, China could first make progress in the deployment of more pollution control facilities and then improve their operational performance. The resulting low technological market entry barriers could help to build enough industrial capacity to meet the huge demand with prices under control. The strategy in the current practice could be improved to establish not only a large supply industry but also a strong one to enable other countries to move more rapidly in pollution mitigation.

    Air pollution represents a health risk for people living in urban environment. Urban air consists in a complex mixture of chemicals and carcinogens and its effects on health can be summarized in acute respiratory effects, neoplastic nonneoplastic (e.g. chronic bronchitis) chronic respiratory effects, and effects on other organs and systems. Air pollution may be defined according to origin of the phenomena that determine it: natural causes (natural fumes, decomposition, volcanic ash) or anthropogenic causes which are the result of human activities (industrial and civil emissions). Transport is the sector that more than others contributes to the deterioration of air quality in cities. In this context, in recent years, governments of the territory were asked to advance policies aimed at solving problems related to pollution. In consideration of the many effects on health caused by pollution it becomes necessary to know the risks from exposure to various environmental pollutants and to limit and control their effects. Many are the categories of "outdoor" workers, who daily serve the in urban environment: police, drivers, newsagents, etc.

    Full Text Available The aim of this study is to find out the kind of hydromacrophyte composition having the highest capability to reduce nitrate-phosphate pollutant and Microcystis growth in phytoremediation media using Equisetum ramosissium, Typha angustifolia and the combination of both. Microcystis were obtained from Sutami reservoir, then being inoculated in a media grown by hydromacrophytes (E. ramosissium, T. angustifolia and both of the hydromacrophytes in the batch culture system. The number of Microcystis was counted every day within fifteen days. Abiotic factors were observe, including the concentration of nitrate using brucine-colorimetry method and orthophosphate (dissolved phosphate using stannous chloride-colorimetry method on day 0, 6th, 12th and 15th. The growth rate of Microcystis carrying capacity and orthophosphate-nitrate levels among treatments were analysed by ANOVA test. The results showed that E. ramosissium and T. angustifolia in mono and polyculture techniques had similar potentiality to reduce the nitrate and ortophosphate. The concentrations of nitrate and orthophosphate decreased over 70 % in the 6th day after incubation. All of the treatments were able to reduce the carrying capacity of Microcystis up to 46 % , but the growth rates were similar in all media, that is, around 97-170 cells/L/day.

    Moskowitz, P. D.; Fthenakis, V. M.; Kalb, P. D.

    1988-07-01

    Toxic, flammable, and explosive gases may be used in photovoltaic cell research laboratories and in commercial manufacturing facilities. Accidental release of these materials can present hazards to life and property. Accidents can arise from a variety of mechanical and human related failures. These can occur from the time materials are received at the loading dock of the facility to the time treated gases are discharged to the atmosphere through a stack. Each type of initiating event may require a different control approach. These may range from the training and certification of plant workers charged with the handling of gas cylinder hookups to installation of emergency pollution control systems. Since engineering options for controlling released materials are limited, emphasis should be placed on administrative and engineering approaches for preventing such accidents. These are likely to be the most effective approaches for protecting life and property.

    Baudouin, C; Charveron, M; Tarroux, R; Gall, Y

    2002-01-01

    We are increasingly exposed to environmental pollution. Pollutants can be inhaled, ingested or come into contact with the skin depending on the form in which they occur. On metabolization, activation, or accumulation, pollutants can become extremely toxic for the vital organs and this is often related to a strong genotoxic effect. Since the skin acts as a barrier between the organism and the environment, it is frequently directly exposed to pollution. It is very often degraded by polluting agents and acts as an inlet toward other tissues. Numerous studies in man recognize and demonstrate the carcinogenic power of certain pollutants in the digestive and respiratory tracts. The "pollutants" that react most specifically with the skin are: ultraviolet radiation, polycyclic aromatic hydrocarbons (e.g., benzo[a]pyrene), volatile organic compounds (e.g., benzene), heavy metals, and ozone. Ultraviolet radiation, a "physical" pollutant, has been described as being the factor responsible for most skin cancers in man. The genotoxicity of UV light is well documented (type of lesion or mutation, etc.) and its carcinogenic effect is clearly demonstrated in vivo in man. A few epidemiological studies describe the carcinogenicity of certain pollutants such as arsenic or lead on the skin. However, most of the evidence for the role of pollutants in skin cancers comes from in vivo animal studies or from in vitro studies (e.g., PAHs). In this report, different studies are presented to illustrate the research strategies developed to investigate the mechanism of action of "chemical" pollutants and their potential role in human skin pathology. All the study models and the associated techniques of investigation are tools for a better understanding and thus more efficient prevention of the deleterious effects caused by the environment.

    This systematic review aims to report the effectiveness of interventions based on exercise and/or physical environment for reducing falls in cognitively impaired older adults living in long-term care facilities. In July 2014, a literature search was conducted using main databases and specialised sources. Randomised controlled trials assessing the effectiveness of fall prevention interventions, which used exercise or physical environment among elderly people with cognitive impairment living in long-term care facilities, were selected. Two independent reviewers checked the eligibility of the studies, and evaluated their methodological quality. If it was adequate, data were gathered. Fourteen studies with 3,539 participants using exercise and/or physical environment by a single or combined approach were included. The data gathered from studies that used both interventions showed a significant reduction in fall rate. Further research is needed to demonstrate the effectiveness of those interventions for preventing falls in the elderly with cognitive impairment living in long-term care establishments.

    Full Text Available Population growth leads to water scarcity in terms of both quality and quantity. Agricultural and urban watersheds potentially produce more pollutantsthan forested area. It is considered that forested area has potential in storing and protecting water supply in such a way that water distribution and quality can be guaranteed. The objective of  the study was to determine the relationship between the percentages of forested area in a watershed with the water quality. Thestudy was conducted in 2010in GrojokanSewu Sub-watershed, Karanganyar District, Central Java. Using GIS (Geographic Information System, this sub-watershedwas divided into four sub-sub-watershedswith different percentages of forested areas. Water samples were collected in each sub-sub-watershedto find out the relationship between the forested area and the total dissolvedsolids, turbidity, sodium, nitrite, nitrate, sulfate and organic matters. The statistical analysis indicates relationships in quadratic form between sodium, nitrite, TDS, sulfate and organic matters with the percentage of  forested area (R2=0.99, R2=0.99, R2=0.98, R2=0.95 and R2=0.77, respectively. The relationships are different from those of turbidity and nitrate that have low R2 (R2=0.28 and R2=0.36 values. It implies that the forested area is capable to reduce sodium, nitrite, TDS, sulfate and organic matters, and thus water pollutants can be reduced by forest formation as it can filter water through retention of sediments and nutrients.

    Full Text Available Abstract This paper identifies and characterizes the environmental maturity level of local and multinational high-technology corporations located in Brazil. This characterization is achieved by discussing the adoption of environmental management practices and considering aspects of the productive process stage. An eight-case study was conducted through data triangulation using interviews with employees in diverse organizational areas, direct observations and secondary data. The results indicate the differences in environmental positioning among the studied corporations with a predominance of preventive practices, i.e., an emphasis on eco-efficiency and compliance with legislation. It was also noted that environmental concerns in the corporations are related to internationalization and, in some cases, to the pressure exerted by corporations that represent the brand of the products produced in Brazil. Moreover, the adoption of environmental practices based on the productive process stage supported the environmental maturity classifications of the studied companies.

  8. Boring crustaceans damage polystyrene floats under docks polluting marine waters with microplastic.

    2012-09-01

    Boring isopods damage expanded polystyrene floats under docks and, in the process, expel copious numbers of microplastic particles. This paper describes the impacts of boring isopods in aquaculture facilities and docks, quantifies and discusses the implications of these microplastics, and tests if an alternate foam type prevents boring. Floats from aquaculture facilities and docks were heavily damaged by thousands of isopods and their burrows. Multiple sites in Asia, Australia, Panama, and the USA exhibited evidence of isopod damage. One isopod creates thousands of microplastic particles when excavating a burrow; colonies can expel millions of particles. Microplastics similar in size to these particles may facilitate the spread of non-native species or be ingested by organisms causing physical or toxicological harm. Extruded polystyrene inhibited boring, suggesting this foam may prevent damage in the field. These results reveal boring isopods cause widespread damage to docks and are a novel source of microplastic pollution.

    Air pollution is composed of particulate matter (PM) and gaseous pollutants, such as nitrogen dioxide and ozone. PM is classified according to size into coarse particles (PM10), fine particles (PM2.5) and ultrafine particles. We aim to provide an original review of the scientific evidence from epidemiological and experimental studies examining the cardiovascular effects of outdoor air pollution. Pooled epidemiological studies reported that a 10μg/m(3) increase in long-term exposure to PM2.5 was associated with an 11% increase in cardiovascular mortality. Increased cardiovascular mortality was also related to long-term and short-term exposure to nitrogen dioxide. Exposure to air pollution and road traffic was associated with an increased risk of arteriosclerosis, as shown by premature aortic and coronary calcification. Short-term increases in air pollution were associated with an increased risk of myocardial infarction, stroke and acute heart failure. The risk was increased even when pollutant concentrations were below European standards. Reinforcing the evidence from epidemiological studies, numerous experimental studies demonstrated that air pollution promotes a systemic vascular oxidative stress reaction. Radical oxygen species induce endothelial dysfunction, monocyte activation and some proatherogenic changes in lipoproteins, which initiate plaque formation. Furthermore, air pollution favours thrombus formation, because of an increase in coagulation factors and platelet activation. Experimental studies also indicate that some pollutants have more harmful cardiovascular effects, such as combustion-derived PM2.5 and ultrafine particles. Air pollution is a major contributor to cardiovascular diseases. Promotion of safer air quality appears to be a new challenge in cardiovascular disease prevention.

    Full Text Available Abstract Background Compared to the general elderly population, those institutionalized in LTC facilities have the highest prevalence of osteoporosis and subsequently have higher incidences of vertebral and hip fractures. The goal of this study is to determine how well nurses at LTC facilities are educated to properly administer bisphosphonates. A secondary question assessed was the nurse's and PSW's attitudes and beliefs regarding the role and benefits of vitamin D for LTC patients. Methods Eight LTC facilities in Hamilton were surveyed, and all nurses were offered a survey. A total 57 registered nurses were surveyed. A 21 item questionnaire was developed to assess existing management practices and specific osteoporosis knowledge areas. Results The questionnaire assessed the nurse's and personal support worker's (PSWs education on how to properly administer bisphosphonates by having them select all applicable responses from a list of options. These options included administering the drug before, after or with meals, given with or separate from other medications, given with juice, given with or without water, given with the patient sitting up, or finally given with the patient supine. Only 52% of the nurses and 8.7% of PSWs administered the drug properly, where they selected the options: (given before meals, given with water, given separate from all other medications, and given in a sitting up position. If at least one incorrect option was selected, then it was scored as an inappropriate administration. Bisphosphonates were given before meals by 85% of nurses, given with water by 90%, given separately from other medication by 71%, and was administered in an upright position by 79%. Only 52% of the nurses and 8.7% of PSWs surveyed were administering the drug properly. Regarding the secondary question, of the 57 nurses surveyed, 68% strongly felt their patients should be prescribed vitamin D supplements. Of the 124 PSWs who completed the survey

    2017-04-01

    Among the risks caused by extreme events, the potential spread of pollutants stored in land hotspots due to floods is an aspect that has been rarely examined with a risk-based approach. In this contribution, an attempt to estimate pollution risks related to flood events of land pollution hotspots was carried out. Flood risk has been defined as the combination of river flood hazard, hotspots exposure and vulnerability to contamination of the area, i.e. the expected severity of the environmental impacts. The assessment was performed on a geographical basis, using geo-referenced open data, available from databases of land management institutions, authorities and agencies. The list of land pollution hotspots included landfills and other waste handling facilities (e.g., temporary storage, treatment and recycling sites), municipal wastewater treatment plants, liquid waste treatment facilities and contaminated sites. The assessment was carried out by combining geo-referenced data of pollution hotspots with flood hazard maps. We derived maps of land pollution risk based on geographical and geological properties and source characteristics available from environmental authorities. These included information about soil particle size, soil hydraulic conductivity, terrain slope, type of stored pollutants, the type of facility, capacity, size of the area, land use, etc. The analysis was carried out at catchment scale. The case study of the Arno river basin in Tuscany (central Italy) is presented.

    The I.N.E.R.I.S. (Institut National de l'Environnement Industriel et des Risques) report relative to the consequences of cleaning operations following the pollution bred by the Erika wreck gives the following conclusions: whatever the pollutants are, the carcinogen risks by pulmonary way are negligible for people assigned to the beaches cleaning; the general carcinogen effects, linked to benzopyrene in organism after skin crossing, have been evaluated as negligible; there is a non negligible risk for the embryo-fetal development linked to the benzopyrene skin crossing; It is not possible to tell if the skin cancer risk is or not negligible, because of the uncertainty of the dose effectively absorbed by the skin and the lack of acceptable toxicological references; the risks linked to the volatile organic compounds are negligible; an uncertainty exists on the risks linked to the thiophene family that have not been determined, because of the deficiency of base data. For the second study, whatever the studied scenario, the R.I.V.M. (Riijksinstituut Voor Volksgezondheid en mileuhygiene) Dutch organism report concludes to a risk qualified as acceptable for the voluntary workers and professionals, included the birds cleaners. The risk of skin cancer consecutive to the skin exposure has been characterized with a dose response relationship model coming from previous works of the R.I.V.M. (N.C.)

    The habitat protection and pollution provisions of the Canadian Fisheries Act are designed for the protection and conservation of fish habitat. Section 35 of the Act prohibits any project that would cause the harmful alteration, disruption or destruction of fish habitat, unless authorized by the Department of Fisheries and Oceans (DFO). This report describes the administration and enforcement procedures of the Fisheries Act during the fiscal year 1996-1997. The three partners that play an important role in the conservation of fisheries and fish habitat are the provinces, territories and First Nations. A summary of policy issues which faced the Habitat Program in 1996-97 are described. The report also describes the Fraser River Action Plan and the St. Lawrence Vision 2000. Both these programs are designed to improve the environmental health and productivity of the watersheds. A number of other projects which have the potential to impact fish and fish habitat are also discussed. Among these Voisey`s Bay mine development in Labrador, an oil transshipment facility in Placentia Bay, Newfoundland, the Star Lake Hydroelectric development in central Newfoundland, the fish passage problem at Petitcodiac Causeway in New Brunswick, the fixed link project in Northumberland Strait, the Kemess South and Huckleberry Copper/Gold mines in British Columbia, developments on the Columbia River in British Columbia, diamond drilling in the Northwest Territories, the Cheviot Mine in Alberta, roads built through the Sunpine Forest in Alberta, and uranium mines in Elliot Lake, Ontario and in Saskatchewan are briefly described as examples of projects requiring involvement by Fisheries and Oceans Canada. 6 tabs.

    Airtightness of housing has been in progress as a part of energy saving measures for buildings such as housing facilities. With attention given to moisture and dew condensation inside rooms accompanying the airtightness, this paper explains the resultant problems of and measures for pollution caused by microorganism (mold, bacteria, mites). A number of molds existing in the normal environment are called fungi, multiplying by means of hyphae and spores. Their growing speed reportedly increases more conspicuously under a higher humidity, reaching the speed nearly 20 times faster under 100% humidity than under 55%. Fungi also give rise to allergens, odors, etc., for the health. There has been a notorious case of bacteria called Legionnaires disease in which soil bacteria caused a great number of patients through the cleaning tower and the air conditioning ducts. As for mites, their dead bodies and excrement become allergens, causing various symptoms including asthma, the mechanism of which has been clarified. 19 refs., 11 figs., 4 tabs.

    Geophysicists are alarmed at the electromagnetic pollution of a research site in the Antarctic specifically set aside to study the ionosphere and magnetosphere. A private New Zealand communications company called Telecom recently constructed a satellite ground station within the boundaries of this Site of Special Scientific Interest (SSSI), protected since the mid-1970s. The placement of a commercial facility within this site sets an ominous precedent not only for the sanctity of other SSSIs, but also for Specially Protected Areas—preserves not even open to scientific research, such as certain penguin rookeries.The roughly rectangular, one-by-one-half mile site, located at Arrival Heights not far from McMurdo Station, is one of a number of areas protected under the Antarctic treaty for designated scientific activities. Many sites are set aside for geological or biological research, but this is the only one specifically for physical science.

  10. Psychiatric aspects of air pollution.

    Science.gov (United States)

    Lundberg, A

    1996-02-01

    Psychological and toxic effects of air pollution can lead to psychiatric symptoms, including anxiety and changes in mood, cognition, and behavior. Increased levels of some air pollutants are accompanied by an increase in psychiatric admissions and emergency calls and, in some studies, by changes in behavior and a reduction in psychological well-being. Numerous toxic pollutants interfere with the development and adult functioning of the nervous system. Manifestations are often insidious or delayed, but they can provide a more sensitive indicator of toxic effects than cancer rates or mortality data. Other medical effects of air pollution, such as asthma, can indirectly affect psychological health. The sick building syndrome and multiple chemical sensitivity are conditions with toxicologic and psychiatric aspects. Psychosocial stress can cause symptoms similar to those of organic mental disorders. Reactions to stress depend on cultural, individual, and situational variables. We must understand these factors to be able to alleviate and prevent the consequences of environmental trauma. Expanded research is recommended in three main areas: (1) how people perceive and cope with environmental health risks, (2) the effects of air pollution on behavior and neuropsychological functioning, and (3) neurotoxicologic evaluation of air pollutants with both behavioral and in vitro studies.

    2017-01-01

    Objective: Globally, the number of people living with human immunodeficiency virus (PLHIV) particularly in sub-Saharan Africa is growing. This has been resulted in increased number of tuberculosis (TB) new cases. To control burden of TB among PLHIV, a number of collaborative TB/HIV activities were recommended. However, data about collaborative TB/HIV services in the study area is scarce. The objective of this study is to assess intensified TB case finding, implementation of isoniazid preventive therapy (IPT) and associated factors among PLHIV. Methods: A facility based cross-sectional study design was employed among 419 randomly selected PLHIV from public health facilities of Harari region. Systematic sampling method was used to obtain sample from each health facilities. Interviewer-administered questionnaire was used to collect data. Data were entered into EpiData and analyzed by SPSS statistical software. Multivariate logistic regression analysis was conducted to determine the presence of association between variables using odds ratio with 95% confidence interval and association was declared significant at P ≤ 0.05. Results: One hundred fifteen (75.2%) of the respondents reported that they offered screening for TB during their HIV chronic cares and 94 (29.8%) of them were found to be positive for active TB. Female sex [AOR 2.51; 95%CI (1.52, 6.14)], educated patients [AOR 0.52; 95%CI (0.21, 0.83)], CD4 count greater than 350 cells/dl3 [AOR 0.62; 95%CI(0.22,0.82)], Antiretroviral Therapy (ART) initiation [AOR 0.50; 95%CI (0.35, 0.88)] and missing dose of ART [AOR 2.57; 95%CI (1.21, 5.32)] were significantly associated with TB infection. Nearly four-fifth (78.7 %) of the study participants were provided IPT. Conclusions: Screening of TB among PLHIV and implementation of IPT in the region is lower when compared to the findings of other studies conducted in different parts of the country and needs to be improved through implementation of national and international

  1. Air pollution and stroke - an overview of the evidence base.

    Science.gov (United States)

    Maheswaran, Ravi

    2016-08-01

    Air pollution is being increasingly recognized as a significant risk factor for stroke. There are numerous sources of air pollution including industry, road transport and domestic use of biomass and solid fuels. Early reports of the association between air pollution and stroke come from studies investigating health effects of severe pollution episodes. Several daily time series and case-crossover studies have reported associations with stroke. There is also evidence linking chronic air pollution exposure with stroke and with reduced survival after stroke. A conceptual framework linking air pollution exposure and stroke is proposed. It links acute and chronic exposure to air pollution with pathways to acute and chronic effects on stroke risk. Current evidence regarding potential mechanisms mainly relate to particulate air pollution. Whilst further evidence would be useful, there is already sufficient evidence to support consideration of reduction in air pollution as a preventative measure to reduce the stroke burden globally.

  3. The difficulties of "polluter pays" policy in agricultural pollution in UK and methods to improve it

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Agricultural wastes pollution became serious after great improvement in technology and the encouragement of production for the government since the end of the World War Ⅱ. Economists and environmental scholars suggested that "polluter pays" policy be employed in agricultural pollution control. However, it was hard to implement "'polluter pays " policy alone in agricultural wastes pollution. In practice, there were two social factors which contributed to the improvement of water quality in the southwest of United Kingdom. One method is to communicate with farmers and then give farmers some advice or exhortation on facilities and management. The other method is to get up a telephone hotline for public to report water quality and probable pollution. Therefore, the consideration and combination of social factors in the control of agricultural wastes pollution are necessary and important. Education of basic natural sciences relevant to agricultural pollution, system management of agricultural pollutants and laws relevant to agricultural pollution is suggested to be the third social factor that British government can consider.

    Haber, Guy; Witberg, Guy; Danenberg, Haim

    2007-10-01

    Cardiovascular atherothrombosis is the most common cause of death globally, with several well-known risk factors. Air pollution is a byproduct of fuel combustion by motor vehicles, power plants and industrial factories. It is composed of gases, fluids and particulate matter (PM) of different sizes, which include basic carbon, organic carbonic molecules and metals such as vanadium, nickel, zinc and iron. These particles are subdivided by their median size, a major contributing factor for their capability to enter the human body through the respiratory system. Most of the epidemiological studies have shown correlation between acute and long-term exposure to air pollution elements and cardiovascular morbidity in general, and angina pectoris and acute myocardial infarction specifically. Physiological studies have found different arrhythmias as the etiologic cause of cardiovascular morbidity and mortality following exposure to air pollution. A major finding was a decline in heart rate variability, a phenomenon known as endangering for cardiovascular morbidity and mortality, especially in patients after acute myocardial infarction. To date, several pathways have been proposed, including a hypercoagulable state following an inflammatory response, cardiac nervous autonomic disequilibrium, endothelial dysfunction with blood vessel contraction and direct toxic impact on cardiac muscle. Additional research is needed for clarifying the pathophysiological pathways by which air pollution affects the cardiovascular system. That might allow forthcoming with preventive measures and correct treatment, and hence a decrease in cardiovascular morbidity and mortality. Another important target is dose-outcome correlation curves for safety threshold calculation as a basis for air pollution regulations.

  13. Pricing Mechanism Design for Centralized Pollutant Treatment with SME Alliances.

    Science.gov (United States)

    Li, Yuyu; Huang, Bo; Tao, Fengming

    2016-06-22

    In this paper, we assume that a professional pollutant treatment enterprise treats all of the pollutants emitted by multiple small and medium-sized enterprises (SMEs). In order to determine the treatment price, SMEs can bargain with the pollutant treatment enterprise individually, or through forming alliances. We propose a bargaining game model of centralized pollutant treatment to study how the pollutant treatment price is determined through negotiation. Then, we consider that there is a moral hazard from SMEs in centralized pollutant treatment; in other words, they may break their agreement concerning their quantities of production and pollutant emissions with the pollutant treatment enterprise. We study how the pollutant treatment enterprise can prevent this by pricing mechanism design. It is found that the pollutant treatment enterprise can prevent SMEs' moral hazard through tiered pricing. If the marginal treatment cost of the pollutant treatment enterprise is a constant, SMEs could bargain with the pollutant treatment enterprise individually, otherwise, they should form a grand alliance to bargain with it as a whole.

  18. The pollution intensity of Australian power stations: a case study of the value of the National Pollutant Inventory (NPI).

    Science.gov (United States)

    Tang, Minmeng; Mudd, Gavin M

    2015-12-01

    This paper presents a comprehensive analysis of the pollutant emissions from electrical generation facilities reported to Australia's National Pollutant Inventory (NPI). The data, in terms of pollutant intensity with respect to generation capacity and fuel source, show significant variability. Based on reported data, the dominant pathway and environmental segment for emissions is point-source air emissions. Surprisingly, pollutant emissions from power stations are generally a very small fraction of Australia's facility and diffuse emissions, except for F, HCl, NO(x), PM2.5, SO2 and H2SO4 (where it constitutes between 30 and 90% of emissions). In general, natural gas and diesel facilities have higher organic pollutant intensities, while black and brown coal have higher metal/metalloid pollutant intensities and there is a wide variability for inorganic pollutant intensities. When examining pollutant intensities with respect to capacity, there is very little evidence to show that increased scale leads to more efficient operation or lower pollutant intensity. Another important finding is that the pollutant loads associated with transfers and reuse are substantial, and often represent most of the reported pollutants from a given generation facility. Finally, given the issues identified with the NPI data and its use, some possible improvements include the following: (i) linking site generation data to NPI data (especially generation data, i.e., MWh); (ii) better validation and documentation of emissions factors, especially the methods used to derive and report estimates to the NPI; (iii) using NPI data to undertake comparative life cycle impact assessment studies of different power stations and fuel/energy sources, or even intensive industrial regions (especially from a toxicity perspective) and (iv) linking NPI data in a given region to ongoing environmental monitoring, so that loads can be linked to concentrations for particular pollutants and the relevant guidelines

    Full Text Available Due to its biological diversity wetland is considered the world's natural wealth museums and because of the natural functions and economic values they are the most important ecosystems on earth. The studies to identify the water quality of wetlands, their biodiversity, environmental pressures faced by efforts and protection methods have gained importance in our country. In particular, heavy metal and trace element pollution is one of the most important problems in wetlands affecting water quality and aquatic organisms. In this study, trace elements and contaminants temporal variation of pollution sources of trace elements was conducted to determine the effects of pollution in Lake Uluabat which is one of Turkey's most important wetlands identified as an area protected under the RAMSAR. In Uluabat Lake, five different stations were selected taking into account the distance to pollution sources, different depths and hydrodynamic properties. In the years of 2003-2004 (1st term and 2008-2009 (2nd term monthly water samples were taken and dissolved concentrations of Boron (B, chromium (Cr, Lead (Pb, Nickel (Ni elements were examined between years. As a result of the evaluations, seasonal factors, industrial discharges and agricultural activities are seen to be effective on changes in pollution. In particular, high concentrations of B elements thought to be due to take place by geological structure of the Lake Basin which is rich in boron and boron operating facilities in this basin. In order to prevent pollution of the water quality of Lake Uluabat it is necessary to be monitored at regular intervals and for the control of pollutants, all of the technical studies should be carried out in the Lake Basin in conjunction with participatory approaches of scientific and public institutions.

    2014-09-01

    Full Text Available In the past 30 years, China’s economy has experienced rapid development, which led to a vast increase in energy consumption and serious environmental pollution. Among the different types of pollution, heavy metal pollution has become one of the major environmental issues in China. A number of studies show that high level of heavy metal exposure is a frequent cause of permanent intellectual and developmental disabilities. In recent years, some traditional pollutants, such as sulfur dioxide and carbon dioxide, have been put under control in China. However, heavy metal pollution, which poses even greater risks to public health and sustainable development, has yet to gain policymakers’ attention. The purpose of this paper is to explore effective countermeasures for heavy metal pollution in China. The present study reviews the current status of China’s heavy metal pollution and analyzes related public policies and countermeasures against that pollution. It also presents a few recommendations and measures for prevention of heavy metal pollution.

    Land pollution is described in numerous ways by various societies. Pollutants of land are material by-products of human activity and range from environmentally ineffective to positively toxic. The pollution of land by man is centuries old and correlates directly with economy, technology and population. In order to remotely sense land pollution, standards or thresholds must be established. Examples of the potential for sensing land pollution and quality are presented. The technological capabilities for remotely sensed land quality is far advanced over the judgment on how to use the sensed data. Until authoritative and directive decisions on land pollution policy are made, sensing of pollutants will be a random, local and academic affair.

  6. Regulations Concerning Agriculture and Air Pollution

    Full Text Available The main issues related to the atmospheric pollution are the stratospheric ozone depletion, the transboundary air pollution, the troposphere air quality and the climate change. The three last decades have seen the birth of several measures for the atmosphere safeguard. Agricultural activities play a key role in determining, preventing and mitigating atmospheric pollution. The emission to atmosphere of different ozone-depleting substances is regulated by the Montreal Protocol. The role of agriculture activity in ozone depletion is linked to the utilization of methyl bromide as soil sterilant and to the emission of nitrogen oxides and nitrous oxide, from agricultural soils. The Convention on long-range transboundary air pollution regulates the emission of several pollutants, i.e. sulphur dioxide, nitrogen oxides, ammonia, non methane volatile organic compounds, carbon monoxide, heavy metals, persistent organic pollutants, and tropospheric ozone. The agriculture sector is responsible for a large part of the emissions of ammonia and nitrogen oxides, mainly through manure management and nitrogen fertilization, and of most persistent organic pollutants, largely used in the past as insecticides and fungicides. The increase of the greenhouse gases (GHGs concentration in the atmosphere is under the control of the Kyoto Protocol. Agriculture accounts for 59-63% of global non-CO2 GHGs emissions but at the same time it contributes to the atmospheric CO2 concentration stabilisation through the substitution of fossil fuels by biofuels and the sequestration of C in soil and vegetal biomass. In this paper we provide an outline of the numerous scientific and legislative initiatives aimed at protecting the atmosphere, and we analyse in detail the agriculture sector in order to highlight both its contribution to atmospheric pollution and the actions aimed at preventing and mitigating it.

  7. On the Incorporation of Greenhouse Gases Emission into the Regulatory Scope of the Atmospheric Pollution Prevention and Control Law%《大气污染防治法》将温室气体 排放纳入控制体系的评析

    对于温室气体控制是否应纳入《大气污染防治法》的调整范畴,一直都有争议. 不应将温室气体控制纳入《大气污染防治法》的调整范畴,这不仅是由于温室气体不属于大气污染物,也是由我国现阶段所处的国际和国内环境决定的. 温室气体主要来源于能源生产等"上游活动"和公众生活消费等"下游活动". 我们应对其进行上堵下疏:一方面力促清洁生产,另一方面倡导低碳生活,将市场机制与行政手段结合起来,多管齐下共同控制温室气体排放,没有必要将温室气体控制纳入《大气污染防治法》的调整范畴.%It has always been controversial whether or not to incorporate greenhouse gases control into the regulatory scope of Atmospheric Pollution Prevention and Control Law of the People' s Republic of China.Green-house gases control should not be incorporated into the regulatory scope of Atmospheric Pollution Prevention Law, not only because greenhouse gases do not belong to the atmospheric pollutants, but also as a result of Chi-na' s current international and domestic environment.Greenhouse gases are mainly derived from the upstream activities, e.g., energy production;and the downstream activities, e.g., public consumption, etc.We will stop the flow from the upstream and dredge the channel to the downstream by promoting cleaner energy produc-tion and advocating low-carbon life.Multi-pronged methods should be employed to control greenhouse gases by combining market mechanism with administrative means.Thus, there is no necessity to incorporate greenhouse gases control into the regulatory scope of Atmospheric Pollution Prevention Law.

    Pollution derived from traffic can be considered one of the major problems of modern cities. Although considerable efforts have been devoted to gathering information about pollution and its control, little attention has been paid to the analysis of relationships between pollution distribution and town planning. The existence of these relationships would enable better prediction and prevention of pollution through town planning. In this work, an analysis of one pollutant derived from traffic (urban noise) in 27 cities is presented. Non-parametric tests and ROC analyses were employed, using the equivalent sound level (L(eq)) values as the dependent variable. For the characterization of the pollutant, an alternative concept to accessibility is analyzed: the concept of functionality. Results of statistical inferential analysis showed the existence of significant differences between the sound levels of the different category results, confirming that noise is stratified in the studied cities and that the five categories proposed based in the concept of functionality highlight this noise stratification. Moreover, high sensitivity and low non-specificity were obtained by using ROC analysis. Results of this analysis also showed an overall average value of prediction capacity close to 90%. Therefore, because the proposed categories highlight the noise stratification of the studied pollutant in all the towns studied, the functionality concept can be considered an interesting tool for urban planning and for designing pollution prevention policies. Finally, as traffic is a source of other urban pollutants, the concept of functionality may be a new concept for wide environmental pollution management.

    Recent episodes of nosocomial tuberculosis, sometimes due to multiresistant strains, in HIV infected patients in the USA has led to the need for new prevention measures against the transmission of Mycobacterium tuberculosis in health care facilities. Tuberculosis is transmitted in Pflügge droplets generated when contagious persons cough. After drying, the droplets become aerosolized solid particles which are rapidly dispersed by air flow within the patient's room. People exposed to the same air are thus at high risk of being contaminated. If the air pressure in the patient's room is higher than the rest of the facility, the air coming form the room may contaminate personnel and other patients elsewhere in the facility. Infecting particles can be eliminated rapidly if the room air is ventilated outdoors. If the ventilation is strong enough so that air constantly circulates from the corridor into the room, infecting particles can no longer diffuse to the rest of the ward. It is also possible to use ultraviolet C light to disinfect the air, either within the room or within the ventilation system. These two basically simple systems are the fundamental environmental and prevention measures needed to limit tuberculosis spread in health care facilities. These methods are however technically complex, costly and require constant evaluation and maintenance by specialized personnel. In addition the potential side effects of ultraviolet waves could considerably reduce their application. These environmental methods, which are complementary methods, only have a meaning if the elementary measures for preventing the transmission of tuberculosis are correctly applied.(ABSTRACT TRUNCATED AT 250 WORDS)

    There are more than a hundred textile industries in Turkey that discharge large quantities of dye-rich wastewater, resulting in water pollution. Such effluents must be treated to meet discharge limits imposed by the Water Framework Directive in Turkey. Industrial treatment facilities must be required to monitor operations, keep them cost-effective, prevent operational faults, discharge-limit infringements, and water pollution. This paper proposes the treatment of actual textile wastewater by vertical flow constructed wetland (VFCW) systems operation and monitoring effluent wastewater quality using fuzzy logic with a graphical user interface. The treatment performance of VFCW is investigated in terms of chemical oxygen demand and ammonium nitrogen (NH4-N) content, color, and pH parameters during a 75-day period of operation. A computer program was developed with a fuzzy logic system (a decision- making tool) to graphically present (via a status analysis chart) the quality of treated textile effluent in relation to the Turkish Water Pollution Control Regulation. Fuzzy logic is used in the evaluation of data obtained from the VFCW systems and for notification of critical states exceeding the discharge limits. This creates a warning chart that reports any errors encountered in a reactor during the collection of any sample to the concerned party.

    Water pollution in the Taihu Lake Basin has been the focus of attention in China and abroad for a long time,due to its position in the forefront of urban development in China.Based on data gathering and processing from 84 monitoring sections in this heavily polluted area,this study first analyzes spatial patterns of urbanization and the distribution of river water pollution,and then uses the GeoDa bivariate spatial autocorrelation model to investigate the spatial correlation between urbanization and river water pollution at the scale of township units.The results show that urbanization has adverse impacts on water pollution,and the influence varies in different levels of development areas.The urban township units have the highest level of urbanization and highest pollution,but the best water quality; the suburban units have lower level of urbanization,but higher pollution and worse water quality;however the rural units have the lowest level of urbanization and lowest pollution,mainly affected by upstream pollution,but worst water quality.Lastly,urban and rural planning committees,while actively promoting the process of development in the region,should gradually resolve the issue of pollution control lagging behind urban life and urban development,giving priority to construction of centralized sewage treatment facilities and associated pipeline network coverage in the rural areas and suburban areas.

    Mathematical models for the problem of maintaining a specified groundwater quality while permitting solute waste disposal at various facilities distributed over space are discussed. The pollutants are assumed to be chemically inert and their concentrations in the groundwater are governed by linear equations for advection and diffusion. The aim is to determine a disposal policy which maximises the total amount of pollutants released during a fixed time T while meeting the condition that the concentration everywhere is below prescribed levels.
