This book was released on 2001-06-07 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a risk-based framework for developing and implementing strategies to manage PCB-contaminated sediments at sites around the country. The framework has seven stages, beginning with problem definition, continuing through assessment of risks and management options, and ending with an evaluation of the success of the management strategy. At the center of the framework is continuous and active involvement of all affected parties-particularly communities-in the development, implementation, and evaluation of the management strategy. A Risk-Management Strategy for PCB-Contaminated Sediments emphasizes the need to consider all risks at a contaminated site, not just human health and ecological effects, but also the social, cultural, and economic impacts. Given the controversy that has arisen at many PCB-contaminated sites, this book provides a consistent, yet flexible, approach for dealing with the many issues associated with assessing and managing the risks at Superfund and other contaminated sites.

Available in PDF, EPUB and Kindle. Book excerpt: Shipyard workers and active duty personnel have the potential to be exposed to various congeners of Polychlorinated Biphenyls (PCBs) during operational, maintenance and disposal scenarios. On 6 December 1994 the US Environmental Protection Agency (EPA) proposed a revision of the PCB ruling which would significantly impact Navy O & M costs and limit options for disposal of ships and submarines. The significant drivers to the EPA criteria were assessed. Additional occupational samples were collected to provide a statistically significant data base from which to evaluate possible exposure. No samples were identified with PCB in the vapor phase, therefore, inhalation was not considered a pathway of concern. Dermal exposure was found to be the only potential exposure route. A probabilistic risk assessment was conducted for both shipyard workers and crew members. The level of risk was determined to be acceptable for both active duty and shipyard workers. The approach presented here is applicable for PCB exposure in all three services.

This book was released on 2012-12-02 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: The chemical industry is increasingly faced with problems arizing from chemicals produced during the manufacture of halogenated biphenyls or phenols. Knowledge of these chemicals and their destructive properties is sporadic, and the acute toxicity of this group varies widely. This informative revised edition presents the chemistry, environmental pollution problems, animal toxicology and information about structure-activity relationships. A brief overview is given of worker exposure and occupational illness. The book is divided into three parts: chemistry and environmental contamination; experimental toxicology; and human exposure and effects. Because of the great deal of interest in these compounds much new research work has been conducted since the first edition of this book was published. This revised edition has retained the effectiveness and clarity of the first edition, while being supplemented with new information, condensed old information, and examples of recent incidents.

Download or read book PCBs written by Larry G. Hansen and published by University of Illinois Press. This book was released on 2023-12-11 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: Though polychlorinated biphenyls (PCBs) have been banned in the United States for more than thirty years, the toxic effects of their presence in local environments continue to be a significant public health concern. PCBs: Human and Environmental Disposition and Toxicology brings together more than fifty established specialists on PCB toxicity to discuss recent trends and specialized investigations of PCB influences on the environment and on humans. Renowned scientists including Paul S. Cooke, Takeshi Nakano, Tomas Trnovec, Deborah C. Rice, Linda S. Birnbaum, and Charles S. Wong present cutting-edge research on Hudson River PCBs, human contamination, homologue profiles, high PCB exposure in Slovakia, and PCB effects on the thyroid hormone, nutrition, and estrogen levels in humans and animals. Focusing on the detection, movement, metabolism, toxicity, remediation, and risk assessment of PCB contamination, this multi-disciplinary study is a valuable resource for regulatory agencies and scientists working with PCBs.

Download or read book Use of Risk Assessment in Evaluating Remediation of PCBs written by Resha M. Putzrath and published by . This book was released on 1993 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment is often used to evaluated the need for, and the potential effectiveness of, remediation of chemical contamination. Estimating the potential residual risk from polychlorinated biphenyls (PCBs) may involve more complex issues than many other chemicals; the presence of more decision points in a risk assessment results in more potential for variation among the analyses performed by different people. For example, the toxicity of PCBs is known to vary with composition, but methods for estimating the toxicity of these complex mixtures for different toxicity endpoints are controversial. Changes in composition of the mixture with time, medium, and place of exposure may also significantly alter the toxicity and concomitant risk. In addition, some of the more interesting potential routes of exposure (e.g., contact with contaminated surface) may be estimated using a variety of models and assumptions, resulting in substantially different assessments of exposure and risk. Although various complex factors should be considered in the risk assessment, simple models should also be used to estimate an upper bound on risk to ensure that a concatenation of conservative assumptions do not result in impossible situations (e.g., predicting exposure to more PCBs by one or several routes than were available for the exposure that was estimated).
Download or read book Polychlorinated Biphenyls written by Obaid Faroon and published by WHO. This book was released on 2003 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polychlorinated Biphenyls (PCBs) are synthetic chlorinated hydrocarbon compounds, produced commercially since 1929 for use in a variety of products including plastics and adhesives, surface coatings, inks, flame retardants, pesticides and paints. PCBs are environmentally persistent, and accumulate in the food chain. They are designated by the Stockholm Convention on Persistent Organic Pollutants as persistent pollutants, and many countries have severely restricted or banned the production of PCBs. This report evaluates the effects of PCBs on human health, caused due to exposure by inhaling contaminated air or ingesting contaminated food and water.

Available in PDF, EPUB and Kindle. Book excerpt: Common analytical methods for detecting and quantifying polychlorinated biphenyls (PCBs) in environmental samples rely on matching a pattern of peaks to a series of Aroclor standards. Due to differences in degradation, partitioning, and metabolism, the PCB pattern in environmental samples can be very different from the Aroclor standards, making identification and quantification of PCBs difficult. To identify an appropriate approach for PCB analyses, the U.S. Environmental Protection Agency Region 9, Biological Technical Assistance Group (BTAG), has considered PCB environmental fate and ecotoxicity, reviewed methods and laboratory capabilities for PCB analysis, and evaluated site-specific data from California and elsewhere. Results of this review indicate analytical methods for routine measurement of specific PCB congeners are currently available, and are cost-effective in comparison with Aroclor- based methods. Accordingly, BTAG has developed a core list of congeners and a phased approach for PCB congener-specific analysis in ecological risk assessments.
