Download or read book Some Drinking water Disinfectants and Contaminants Including Arsenic written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by IARC. This book was released on 2004 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: A working group of 23 experts from 13 countries met in Lyon to evaluate the evidence for carcinogenicity of arsenic (mostly naturally occurring) as a contaminant of drinking-water, and of the water-disinfectant chloramine. The working group also evaluated or re-evaluated four chlorination by-products found in drinking-water, namely chloral hydrate, di- and trichloroacetic acids, and 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (also known as MX). High-level exposure to arsenic in drinking-water occurs in some regions such as China, Latin America, Bangladesh and West Bengal. The Working Group reviewed epidemiological studies of human cancer (mainly ecological studies in Taiwan and Chile, and several case-control and cohort studies) in relation to arsenic in drinking-water. Arsenic in drinking-water (primarily inorganic, as arsenate and to a lesser extent arsenite) was evaluated as carcinogenic to humans (Group 1) on the basis of sufficient evidence for an increased risk for cancer of the urinary bladder, lung and skin. Studies on inorganic arsenic in experimental animals provided limited evidence for its carcinogenicity, but sufficient evidence was found in experimental animals for the carcinogenicity of dimethylarsinic acid (an organic form of arsenic), which produced urinary bladder tumours in rats and lung tumours in mice after oral administration.

Available in PDF, EPUB and Kindle. Book excerpt: Drinking water disinfection has markedly reduced diseases causes by waterborne pathogenic microorganisms. However, an unintended consequence of disinfection and/or oxidation processes is the generation of disinfection byproducts (DBPs) which are formed from the reactions of disinfectants/oxidants with water matrix components. This volume of the Comprehensive Analytical Chemistry Handbook presents recent advances about the formation, identification, and quantification of inorganic and organic DBPs during oxidative processes. The book begins with a first chapter reviewing the most recent non-targeted screening approaches and workflows to characterize DBPs using low-, high-, and ultra-high-resolution mass spectrometry. The second chapter discusses the analysis of inorganic chloramines in waters using on-site and/or in-lab analytical methods. The third chapter provides an overview of the current knowledge about the mechanisms of chlorine dioxide reactions and byproducts formation. The fourth chapter presents some fundamental and practical aspects about ozonation processes in water treatment and provides an overview about ozone reaction mechanisms and byproducts formation. The fifth chapter focuses on the reactivity of halide ions, particularly bromide and iodide, with common oxidants and the role they play in determining the speciation of DBPs in treated waters. The chapter also presents strategies to mitigate the formation of DBPs during oxidation processes. Finally, the last chapter tackles the topic of DBPs formation during potable water reuse. It discusses the formation of DBPs of major concern in both memebrane-based and non-membrane-based potable water reuse treatment schemes. Researchers, water treatment specialists, and regulators will find in this book a valuable and compact resource on several key topics regarding the formation, identification, quantification, and mitigation of DBPs. Identification and quantification of known and unknown DBPs Formation of DBPs during different disinfection/oxidation processes DBPs of concern in new technologies and/or new applications of existing technologies in water treatment

Download or read book Chlorinated Drinking water Chlorination By products written by IARC Working Group on the Evaluation of Carcinogenic Risks to Humans and published by World Health Organization. This book was released on 1991 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluates the carcinogenic risk to humans posed by the consumption of chlorinated drinking-water by two chemicals used in the chlorination of drinking-water by a number of halogenated by-products formed when chlorine interacts with organic matter in water and by a selection of other halogenated compounds found in drinking-water. Chlorination was selected for evaluation because of its widespread use and because potentially carcinogenic by-products have been measured in chlorinated water. The book also includes a separate monograph on cobalt and cobalt compounds. The volume opens with a discussion of the many methodological problems that complicate efforts to assess the carcinogenicity of chlorinated water. Against this background the book evaluates the design and findings of all studies relevant to the carcinogenicity assessment of chlorinated drinking-water two chemicals (sodium chlorite and hypochlorite salts) used in the chlorination of water eight of the by-products most frequently measured in drinking-water and three additional halogenated chemicals detected in drinking-water. Because of the formidable methodological obstacles faced by all investigations only one of these substances could be classified: bromodichloromethane was classified as possibly carcinogenic to humans. The final monograph considers data on metallic cobalt, cobalt alloys including cobalt-containing surgical implants and dental devices and cobalt compounds. In view of the strength of evidence linking cobalt metal powder and cobalt[II] oxide to cancer in experimental animals cobalt and cobalt compounds were classified as possibly carcinogenic to humans.
