Download or read book Phthalate Esters written by Charles Staples and published by Springer. This book was released on 2003-07-31 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phthalate esters are an important class of chemicals widely used in commercial applications, primarily as plasticizers to soften vinyl, but they are also used in consumer products. This book reviews the state of the scientific knowledge of phthalate esters in the environment. Key information reported includes: analytical methodologies; a compilation of concentration measurements in water, sediment, soil, air, dust, and food; plus an assessment of critical exposure pathways. In addition, key physical properties data and fate characteristics that control exposure are reviewed. Also included are pertinent ecotoxicity data and mammalian toxicity and human health information. Finally, the monograph addresses potential environmental risks.

Book excerpt: "Based on these considerations, it has been concluded that di-n-octyl phthalate is not entering the environment in a quantity or concentration or under conditions that are having a harmful effect on the environment or that constitute a danger to the environment upon which human life depends. There are insufficient data to conclude whether DnOP is entering the environment in a quantity or concentration or under conditions that constitute a danger to human life or health"--Synopsis, p. v.
Download or read book Regulated Chemicals Directory 1994 written by ChemADVISOR Inc. Staff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1716 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Regulated Chemicals Directory"lM is meant to be a convenient source of information for everyone who needs to keep up-to-date regarding the regulations and recommendations that pertain to chemical substances. The RCDTM is designed to be the first reference book to consult when beginning compliance efforts. Every regulatory or advisory list used in the RCDTM is keyed to its source, to help readers who need more detailed information on regulations, recommendations, or guidelines readily locate source documents. Some organizations now center their compliance efforts on computerized information stored in cross-referenced databases. A unique feature of the RCDTM is the availability of an electronic version suitable for use on IBM-compatible personal computers, download onto mainframes and CD-ROM players. Both the print and electronic versions are updated with the same timeliness. For more information on the electronic versions of the Regulated Chemicals DirectoryTM, contact Chapman & Hall directly (One Penn Plaza, New York, NY 10119, fax-212-564-1505). Many companies working on product development need information on what may be regulated in the future. The RCDTM provides selected information on pending regulations and in-progress testing lists, which can provide a starting place for tracking future regulatory considerations. Information for the RCDTM is continually gathered and updated. Suggestions from readers for information that should be added to the RCDTM or for other ways to improve the book are welcomed by Chapman & Hall. - Patricia L. Dsida, Pres.

Download or read book Some Chemicals Present in Industrial and Consumer Products Food and Drinking water written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by IARC Monographs on the Evaluat. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides an assessment of the carcinogenicity of 18 chemicals present in industrial and consumer products or food (natural constituents, contaminants, or flavorings) or occurring as water-chlorination by-products. The compounds evaluated include the widely used plasticizer di(2-ethylhexyl) phthalate and the food contaminant 4-methylimidazole. In view of the limited agent-specific information available from epidemiological studies, the IARC Monographs Working Group relied mainly on carcinogenicity bioassays, and mechanistic and other relevant data to evaluate the carcinogenic hazards to humans exposed to these agents.

Download or read book Leading edge Environmental Biodegradation Research written by Lyman E. Pawley and published by . This book was released on 2007 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents new leading-edge research on environmental biodegradation which is the destruction of organic compounds by micro-organisms. Micro-organisms, particularly bacteria, are responsible for the decomposition of both natural and synthetic organic compounds in nature. Mineralisation results in complete conversion of a compound to its inorganic mineral constituents (for example, carbon dioxide from carbon, sulphate or sulphide from organic sulfur, nitrate or ammonium from organic nitrogen, phosphate from organophosphates, or chloride from organochlorine). Since carbon comprises the greatest mass of organic compounds, mineralisation can be considered in terms of CO2 evolution. Radioactive carbon-14 (14C) isotopes enable scientists to distinguish between mineralisation arising from contaminants and soil organic matter. However, mineralisation of any compound is never 100% because some of it (1040% of the total amount degraded) is incorporated into the cell mass or products that become part of the amorphous soil organic matter, commonly referred to as humus. Thus, biodegradation comprises mineralisation and conversion to innocuous products, namely biomass and humus. Primary biodegradation is more limited in scope and refers to the disappearance of the compound as a result of its biotransformation to another product. Compounds that are readily biodegradable are generally utilised as growth substrates by single micro-organisms. Many of the components of petroleum products (and frequent ground-water contaminants), such as benzene, toluene, ethylbenzene, and xylene, are utilised by many genera of bacteria as sole carbon sources for growth and energy.

Download or read book Application of Systematic Review Methods in an Overall Strategy for Evaluating Low Dose Toxicity from Endocrine Active Chemicals written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-08-14 with total page 423 pages. Available in PDF, EPUB and Kindle. Book excerpt: To safeguard public health, the US Environmental Protection Agency (EPA) must keep abreast of new scientific information and emerging technologies so that it can apply them to regulatory decision-making. For decades the agency has dealt with questions about what animal-testing data to use to make predictions about human health hazards, how to perform dose-response extrapolations, how to identify and protect susceptible subpopulations, and how to address uncertainties. As alternatives to traditional toxicity testing have emerged, the agency has been faced with additional questions about how to incorporate data from such tests into its chemical assessments and whether such tests can replace some traditional testing methods. Endocrine active chemicals (EACs) have raised concerns that traditional toxicity-testing protocols might be inadequate to identify all potential hazards to human health because they have the ability to modulate normal hormone function, and small alterations in hormone concentrations, particularly during sensitive life stages, can have lasting and significant effects. To address concerns about potential human health effects from EACs at low doses, this report develops a strategy to evaluate the evidence for such low-dose effects.
