Download or read book Pentachlorophenol and some related compounds written by International Agency for Research on Cancer and published by International Agency for Research on Cancer. This book was released on 2019-10-24 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume of the IARC Monographs provides evaluations of the carcinogenicity of pentachlorophenol, 2,4,6-trichlorophenol, 3,3',4,4'-tetrachloroazobenzene, aldrin, and dieldrin. Pentachlorophenol, aldrin, and dieldrin are classified as persistent organic pollutants under the Stockholm Convention. Pentachlorophenol has been widely used as a wood preservative and insecticide, but its production and use are now restricted. 2,4,6-Trichlorophenol has also been used as a wood preservative and insecticide, and in the synthesis of some fungicides. Aldrin and dieldrin are synthetic organochlorine pesticides used as broad-spectrum soil insecticides for the protection of various food crops, as seed dressings, and to control infestations of pests such as ants and termites. In several countries their use has been banned or severely restricted since the early 1970s. 3,3',4,4'-Tetrachloroazobenzene is not manufactured commercially but is formed during the production and degradation of chloroanilide herbicides such as propanil, linuron, and diuron. Exposure to all five agents considered may occur in the general population as well as in various occupational settings. 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 environmental or occupational exposure of these agents.

Download or read book Ozonation and Biodegradation in Environmental Engineering written by Tatyana Poznyak and published by Elsevier. This book was released on 2018-11-07 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ozonation and Biodegradation in Environmental Engineering: Dynamic Neural Network Approach gives a unified point-of-view on the application of DNN to estimate and control the application of ozonation and biodegradation in chemical and environmental engineering. This book deals with modelling and control design of chemical processes oriented to environmental and chemical engineering problems. Elimination in liquid, solid and gaseous phases are all covered, along with processes of laboratory scale that are evaluated with software sensors and controllers based on DNN technique, including the removal of contaminants in residual water, remediation of contaminated soil, purification of contaminated air, and more. The book also explores combined treatments using both ozonation and biodegradation to test the sensor and controller. Defines a novel researching trend in environmental engineering processes that deals with incomplete mathematical model description and other non-measurable parameters and variables Offers both significant new theoretical challenges and an examination of real-world problem-solving Helps students and practitioners learn and inexpensively implement DNN using commercially available, PC-based software tools
Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Download or read book Pentachlorophenol written by K. Rao and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pentachlorophenol and its salts are used as biocides. Although they are used mainly for preservation and treatment of wood, their antimicrobial, antifungal, herbicidal, insecticidal and molluscicidal properties led to a widespread application of PCP formulations. Bevenue and Beckman reviewed the literature up to 1967 on the chemistry, toxicology and environmental residues of PCP (Residue Rev. , 19: 83- 134, 1967). Significant advances in analytical methodology, recurrent incidents of mortalities of non-target organisms exposed to PCP, regulatory actions pertaining to PCP usage in countries such as Japan and Sweden, and detection of the ubiquitous distribution of PCP in the environment, added to the wealth of recent literature on pentachlorophenol. In spite of the usage of PCP as an antimicrobial agent in drilling and packer fluids during oil-drilling operations in the marine environment, little is known of the toxicity of PCP to marine and estuarine organisms. The purpose of this volume is to present up-to-date information (including a number of new studies on marine and estuarine organisms) on the chemistry, pharmacology and environmental toxicology of pentachlorophenol. This volume is a collection of papers presented at an international symposium sponsored by the U. S. Environmental Protection Agency and The University of West Florida, held at Pensacola Beach, Florida, June 27-29,1977. I am grateful to Norman L.

This is followed by multiorganics, pesticides and organometallic compounds in non-saline waters. Organic compounds in aqueous precipitation are then explored before the book goes on to discuss compounds in soils, including extraction techniques, insecticides, herbicides and fungicides, and organometallic compounds. Finally, the concluding chapters focus on compounds in sediments, providing readers with the latest information in the field and supporting them as they address the important issue surrounding organic material throughout ecosystems. Highlights the latest methods for analyzing a wide range of organic compounds Supports researchers by providing detailed information across a range of ecosystems Includes detailed guidance for assessing complex mixtures of organic compounds in the environment

Download or read book Microbe Induced Degradation of Pesticides written by Shree Nath Singh and published by Springer. This book was released on 2016-09-12 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the microbial degradation of endosulfan, lindane, chlorophenols, organochlorine, aldrin, dieldrin, isoproturon and atrazine, etc. which are commonly used in crop fields to kill the pests. Further, it illustrates the role of degradative enzymes, metabolic pathways of degradation, toxicity of metabolites, and the factors regulating the pesticide degradation. In view of persistence of synthetic pesticides, scientists have discovered suitable microbes, such as bacteria, fungi and algae (naturally occurring or genetically engineered) over the years. After successful trials under laboratory and field conditions, these microbes are being used to degrade chemical pesticides in agriculture. As of now 2.56 billion kg of chemical pesticides is used every year to protect agricultural fields against pest attack. These technologies have been found to be highly effective, eco-friendly and cost-effective without disturbing the agro-ecosystems. As this book contains review articles contributed by various researchers from different countries whose work demonstrates recent advances in microbial degradation of pesticides, it will serve as a ready reckoner and also a valuable quick reference guide for scientists, academicians, cultivators and industrialists alike.
