Download or read book A Class Approach to Hazard Assessment of Organohalogen Flame Retardants written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-08-19 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1970s, flame retardants began to be added to synthetic materials to meet strict flammability standards. Over the years, diverse flame retardants have been manufactured and used in various products. Some flame retardants have migrated out of the products, and this has led to widespread human exposure and environmental contamination. There also is mounting evidence that many flame retardants are associated with adverse human health effects. As a result, some flame retardants have been banned, restricted, or voluntarily phased out of production and use. This publication develops a scientifically based scoping plan to assess additive, nonpolymeric organohalogen flame retardants as a class for potential chronic health hazards under the Federal Hazardous Substances Act, including cancer, birth defects, and gene mutations.

Download or read book Flame Retardant Polymeric Materials written by Eli Pearce and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flammability has been recognized as an increasingly important social and scientific problem. Fire statistics in the United States (Report of the National Commission on Fire Prevention and Control. "America Burning:' 1973) emphasized the vast devastation to life and property--12.000 lives lost annually due to fire. and these deaths are usually caused by inhaling smoke or toxic gases: 300.000 fire injuries: 11.4 billion dollars in fire cost at which 2.7 billion dollars is related to property loss: a billion dollars to burn injury treatment: and 3.3 billion dollars in productivity loss. It is obvious that much human and economic misery can be attributed to fire situations. In relation to this. polymer flammability has been recognized as an in creasingly important social and scientific problem. The development of flame-retardant polymeric materials is a current example where the initia tive for major scientific and technological developments is motivated by sociological pressure and legislation. This is part of the important trend toward a safer environment and sets a pattern for future example. Flame retardancy deals with our basic everyday life situations-housing. work areas. transportation. clothing and so forth-the "macroenvironment" capsule within which "homosapiens" live. As a result. flame-retardant polymers are now emerging as a specific class of materials leading to new and diversified scientific and technological ventures.

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.
Download or read book Human Biomonitoring for Environmental Chemicals written by National Research Council and published by National Academies Press. This book was released on 2006-11-30 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomonitoring—a method for measuring amounts of toxic chemicals in human tissues—is a valuable tool for studying potentially harmful environmental chemicals. Biomonitoring data have been used to confirm exposures to chemicals and validate public health policies. For example, population biomonitoring data showing high blood lead concentrations resulted in the U.S. Environmental Protection Agency's (EPA's) regulatory reduction of lead in gasoline; biomonitoring data confirmed a resultant drop in blood lead concentrations. Despite recent advances, the science needed to understand the implications of the biomonitoring data for human health is still in its nascent stages. Use of the data also raises communication and ethical challenges. In response to a congressional request, EPA asked the National Research Council to address those challenges in an independent study. Human Biomonitoring for Environmental Chemicals provides a framework for improving the use of biomonitoring data including developing and using biomarkers (measures of exposure), research to improve the interpretation of data, ways to communicate findings to the public, and a review of ethical issues.
