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.

Available in PDF, EPUB and Kindle. Book excerpt: The EPA has established regulations which classify four types of disinfection byproducts - TTHMs, haloacetic acids, bromate, and chlorite - and requires public water systems limit these byproducts to specific levels. Most of the information required to comply with these standards is either scattered throughout the literature or derived from confere

This book was released on 2005-01-01 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research was to develop a new approach for HAA analysis that was accurate, reproducible, sufficiently sensitive, and relatively safe and simple to perform. This method involved the use a CE ion analyzer for separation and detection of HAAs. Preliminary results from our laboratory using distilled and deionized water spiked with HAAs indicated that this approach was capable of separating and detecting all nine chlorinated and brominated HAAs. The method detection limit (MDL) for monochloroacetic acid measured in our laboratory was 32 ppb using a bubble cell without any sample pretreatment (i.e. direct aqueous sample injection). Given this unacceptably high MDL, more work was needed to fully develop and test the CE-based method especially with regard to improving method sensitivity.
Download or read book UV visible Spectrophotometry of Water and Wastewater written by Olivier Thomas and published by Elsevier. This book was released on 2007-04-13 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: UV-Visible Spectrophotometry of Water and Wastewater is the first book dedicated to the use of UV spectrophotometry for water and wastewater quality monitoring. Using practical examples the reader is shown how this technique can be a source of new methods of characterization and measurement. Easy and fast to run, this simple and robust analytical technique must be considered as one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (eg. Nitrate, TOC), and simultaneously qualitative information on the global composition of water and its variation.* First electronic library of UV-spectra providing data readily available for researchers and users* Provides a theoretical basis for further research in the field of spectra exploitation* Contains helpful practical applications

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.
