Book Polychlorinated Biphenyls  PCBs   Mammalian and Environmental Toxicology

Download or read book Polychlorinated Biphenyls PCBs Mammalian and Environmental Toxicology written by Stephen Safe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polychlorinated biphenyls (PCBs) have been produced commercially since be fore 1930. They proved to be highly versatile mixtures and their uses continued to expand during the early 1970's even after the unanticipated world-wide en vironmental contamination had been discovered (Jensen et aI. , 1969; Koeman et aI. , 1969). Over 600,000 metric-tons were produced and/or used in the U. S. during this time and it is estimated that worldwide production totaled about 1,200,000 metric-tons (Table 1). With low acute toxicities (Fishbein, 1974), these mixtures were considered gen erally biologically inactive even though industrial exposure had demonstrated he patic and dermatological effects (Fishbein, 1974; Hansen, 1987). Thus, use and disposal were not carefully monitored and it is estimated that one-third of the world-wide production of PCBs has been released into the global environment (Table 1). Table 1.

Book Persistent Organic Pollutants and Toxic Metals in Foods

Download or read book Persistent Organic Pollutants and Toxic Metals in Foods written by Martin Rose and published by Elsevier. This book was released on 2013-05-15 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Persistent organic pollutants (POPs) and toxic elements, such as dioxins, flame retardants, lead and mercury, are substances of major concern for the food industry, the regulator and the public. They persist in the environment, accumulate in food chains and may adversely affect human health if ingested over certain levels or with prolonged exposure. Persistent organic pollutants and toxic metals in foods explores the scientific and regulatory challenges of ensuring that our food is safe to eat. Part one provides an overview of regulatory efforts to screen, monitor and control persistent organic pollutants and heavy metals in foods and includes case studies detailing regulatory responses to food contamination incidents. Part two moves on to highlight particular POPs, toxic metals and metalloids in foods, including dioxins and polychlorinated biphenyls (PCBs), mercury, polycyclic aromatic hydrocarbons (PAHs) and phthalates. Persistent organic pollutants and toxic metals in foods is a standard reference for those in the food industry responsible for food safety, laboratories testing for food chemical safety, regulatory authorities responsible for ensuring the safety of food, and researchers in industry and academia interested in the science supporting food chemical safety. Includes case studies which detail regulatory responses to food contamination incidents Considers the uptake and transfer of persistent organic pollutants in the food chain and the risk assessment of contaminates in food Details perticular persistent organic pollutants, toxic metals and metalloids in foods including polychlorinated biphenyls (PCBs), per- and polyfluoroalkyl substances (PFASs), mercury and arsenic among others

Book Bitumens and Bitumen Emissions  and Some N  and S heterocyclic Polycyclic Aromatic Hydrocarbons

Download or read book Bitumens and Bitumen Emissions and Some N and S heterocyclic Polycyclic Aromatic Hydrocarbons written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 2013 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of bitumens and their emissions, the N-heterocyclic polycyclic aromatic hydrocarbons benz[a]acridine, benz[c]acridine, dibenz[a,h]acridine, dibenz[a,j]acridine, dibenz[c,h]acridine, carbazole and 7H-dibenzo[c,g]carbazole, as well as the S-hetrocyclic polycyclic aromatic hydrocarbons benzo[b]naphtho[2,1-d]thiophene and dibenzothiophene. Bitumens are produced by distillation of crude oil during petroleum refining, and also occur naturally. Bitumens can be divided into six broad classes, according to their physical properties and specifications required for different applications. The major use (about 80%) of bitumens is for road paving; other uses include roofing, waterproofing, sealing and painting. The term "bitumen" should not be confused with "asphalt", which refers to the mixture of bitumen (4-10% by weight), small stones, sand and filler used for road paving. Bitumens are complex mixtures that contain a large number of organic chemical compounds. Application of bitumens may generate emissions (fumes and vapours) that may contain, among volatile and non-volatile compounds, a number of known or probable carcinogens. An IARC Monographs Working Group reviewed epidemiological evidence, animal bioassays, and mechanistic and other relevant data to reach conclusions as to the carcinogenic hazard to humans of various occupations that entail exposure to bitumens and bitumen emissions, including road paving, roofing, and application of mastic asphalt, and to various heterocyclic polycyclic aromatic compounds.

Download or read book America s Children and the Environment written by U.s. Environmental Protection Agency and published by Createspace Independent Publishing Platform. This book was released on 2017-05-31 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: "America's Children and the Environment (ACE)" is EPA's report presenting data on children's environmental health. ACE brings together information from a variety of sources to provide national indicators in the following areas: Environments and Contaminants, Biomonitoring, and Health. Environments and Contaminants indicators describe conditions in the environment, such as levels of air pollution. Biomonitoring indicators include contaminants measured in the bodies of children and women of child-bearing age, such as children's blood lead levels. Health indicators report the rates at which selected health outcomes occur among U.S. children, such as the annual percentage of children who currently have asthma. Accompanying each indicator is text discussing the relevance of the issue to children's environmental health and describing the data used in preparing the indicator. Wherever possible, the indicators are based on data sources that are updated in a consistent manner, so that indicator values may be compared over time.
