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.

Download or read book Ammonia from Chloramine Decay written by Gregory W. Harrington and published by American Water Works Association. This book was released on 2003 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research report focused on the evaluation of the effects of pH on the inactivation of AOB by chloramines and effects of NOM removal and pH on the rate of ammonia release from the chloramine decay. It was found that water utilities should consider employing pretreatment practices that achieve great stability of chloramine residuals. in order to offset the expenses of periodic strategies to deal with nitrification. Other alternatives to consider for nitrification control are advanced NOM removal strategies or alternative pH values for water entering the distribution system.
