Book Synopsis Understanding Risk to Wildlife from Exposures to Per- and Polyfluorinated Alkyl Substances (PFAS) by : Mark S. Johnson
Download or read book Understanding Risk to Wildlife from Exposures to Per- and Polyfluorinated Alkyl Substances (PFAS) written by Mark S. Johnson and published by CRC Press. This book was released on 2021-04-21 with total page 177 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding Risk to Wildlife from Exposures to Per- and Polyfluorinated Alkyl Substances (PFAS) provides the most recent summary of toxicity data relevant to mammals, birds, reptiles, and amphibians, and provides values for use in risk assessment applications. Predicting the bioaccumulation of PFAS in terrestrial wildlife (including humans) has proven to be extremely complex. As a group, PFAS act differently than traditional non-ionic organic molecules, where PFAS can break down and reform, whereas some are demonstrated to be extremely persistent. Where sufficient data are provided, this book establishes toxicity reference values (TRVs), which are derived to assist in characterizing environmental sources of contamination and making risk-based decisions. Features: Provides toxicity reference values (TRVs) for vertebrates (mammals, birds, amphibians) for PFAS, where sufficient data are available, and includes objective supporting background information. Assigns a level of confidence to each TRV to provide the risk assessor with an understanding of the relative uncertainty associated with each value. Presents toxicity data in the formats of scatter diagrams and tables for quick review and assessment. Provides TRVs relevant for screening and decision making This book serves as a useful aid for risk assessors and managers in those industries that have sites contaminated with PFAS, consultants tasked with evaluating risks at such sites, and staff at regulatory agencies at various governmental levels, who need to know how much contamination is considered safe for wildlife. It will also appeal to researchers with an interest in filling the gaps in the current toxicological data for PFAS exposure.
Book Synopsis Toxicants in Food Packaging and Household Plastics by : Suzanne M. Snedeker
Download or read book Toxicants in Food Packaging and Household Plastics written by Suzanne M. Snedeker and published by Springer. This book was released on 2014-08-13 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book serves as a comprehensive resource on toxicants that can be released from food packaging materials and household plastics. Chapters include sources and levels of chemical exposure, known and suspected health effects and the identification of data gaps with recommendations for further research. In addition, regulatory approaches and risk assessment challenges in the United States and Europe are discussed. Chapters cover both the more widely known chemicals that can migrate from food packaging (bisphenol A, perfluorinated chemicals), and household plastics (lead, phthalates, brominated flame retardants), as well as chemicals that are just entering use in food packaging (nanomaterials in polymer food packaging) and chemicals recently identified as migrating from food packaging to food stuffs (phthalates, benzophenones, antimony, methylnaphthalene and the alkylphenols nonylphenol and octylphenol). Chapters on phthalates and brominated flame retardants discuss challenges that arise with the use of replacement chemicals. The health effect sections of chapters have drawn on a wide variety of toxicological endpoints and recommend approaches to better assess toxicological risks in vulnerable human populations. Reflecting the global nature of our food supply and household consumer goods, contributions have been drawn from international experts. A wide range of scientists will find this book to be useful, including toxicologists, environmental health scientists, food scientists, and regulators.
Book Synopsis Science and Decisions by : National Research Council
Download or read book Science and Decisions written by National Research Council and published by National Academies Press. This book was released on 2009-03-24 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk assessment has become a dominant public policy tool for making choices, based on limited resources, to protect public health and the environment. It has been instrumental to the mission of the U.S. Environmental Protection Agency (EPA) as well as other federal agencies in evaluating public health concerns, informing regulatory and technological decisions, prioritizing research needs and funding, and in developing approaches for cost-benefit analysis. However, risk assessment is at a crossroads. Despite advances in the field, risk assessment faces a number of significant challenges including lengthy delays in making complex decisions; lack of data leading to significant uncertainty in risk assessments; and many chemicals in the marketplace that have not been evaluated and emerging agents requiring assessment. Science and Decisions makes practical scientific and technical recommendations to address these challenges. This book is a complement to the widely used 1983 National Academies book, Risk Assessment in the Federal Government (also known as the Red Book). The earlier book established a framework for the concepts and conduct of risk assessment that has been adopted by numerous expert committees, regulatory agencies, and public health institutions. The new book embeds these concepts within a broader framework for risk-based decision-making. Together, these are essential references for those working in the regulatory and public health fields.

Book Synopsis Polyfluorinated Chemicals and Transformation Products by : Thomas P. Knepper
Download or read book Polyfluorinated Chemicals and Transformation Products written by Thomas P. Knepper and published by Springer Science & Business Media. This book was released on 2011-09-21 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to their unparalleled effectiveness and efficiency, polyfluorinated chemicals (PFC) have become essential in numerous technical applications. However, many PFCs brought to market show limited biodegradability, and their environmental persistence combined with toxic and bioaccumulative potential have become a matter of concern in some instances. This volume highlights the synthesis of PFCs, focusing on substances with improved application and environmental properties, which are a challenge for synthetic chemists. Further, modern mass spectrometric techniques for the detection and identification of biotransformation products of PFCs are described. The sorption and leaching behavior of PFC in soil is also addressed in order to predict their fate in the environment. Several contributions discuss the monitoring of PFCs in European surface, ground and drinking waters, treatment options for PFC removal from drinking water, occurrence in food, and the human biomonitoring of PFCs.
Book Synopsis Perfluorinated Chemicals (PFCs) by : Nicholas P. Cheremisinoff
Download or read book Perfluorinated Chemicals (PFCs) written by Nicholas P. Cheremisinoff and published by John Wiley & Sons. This book was released on 2016-11-29 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new volume provides a timely study on the environmental challenges from a specific class of perfluorinated chemical compounds (PFCs) that are now being recognized as a worldwide health threat. Recent studies report that levels of classes of PFCs known as polyfluoroalkyl and perfluoroalkyl (PFASs) exceed federally recommended safety levels in public drinking-water supplies for 6 million people in the United States and that as many as 100 million people could be at risk from exposure to these chemicals. These chemicals occur globally in wildlife and humans. Both PFCAs and PFSAs have been produced for more than 50 years, but have only become of interest to regulators and environmentalists since the late 1990s. Recent advances in analytical methodology has enabled widespread detection in the environment and humans at trace levels. These toxic chemicals have been found in outdoor and indoor air, surface and drinking water, house dust, animal tissue, human blood serum, and human breast milk. Of great concern to communities is the presence of these compounds in a number of drinking water supplies in the U.S. and other countries. This new volume provides a timely explanation of the chemicals, provides a detailed review of the regulations both in the US and European Community, explains the health risk literature, and then explores in great detail available treatment technologies. The volume is a must for public water supply facilities, industrial operations that have historically used these chemicals and face legacy pollution issues, policy makers and the general public.

Book Synopsis Toxicological Profile for Perfluoroalkyls by :
Download or read book Toxicological Profile for Perfluoroalkyls written by and published by . This book was released on 2009 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This toxicological profile for perfluoroalkyls was prepared consistent with guidelines developed by the Agency for Toxic Substances and Disease Registry (ATSDR) and the Environmental Protection Agency (EPA) for the preparation of toxicological profiles. The original guidelines were published in the Federal Register on April 17, 1987. While Perfluoroalkyls are not found on the ATSDR list of Priority Hazardous Substances, ATSDR has determined that a profile for these substances was necessary because data indicate that some perfluoroalkyls are found in the blood of the U.S. general population and in the environment. The agency also determined that it was important to characterize the current available information regarding the health effects from exposure in order to support and inform public health responses and activities by ATSDR and other." -- p. v
