Book Synopsis Iodinated X-ray Contrast Media (ICM) as Precursors to Disinfection Byproduct (DBP) Formation and Enhanced Toxicity as a Function of PH and Chlorinated Oxidant by : Alexis Helen Killinger
Download or read book Iodinated X-ray Contrast Media (ICM) as Precursors to Disinfection Byproduct (DBP) Formation and Enhanced Toxicity as a Function of PH and Chlorinated Oxidant written by Alexis Helen Killinger and published by . This book was released on 2016 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to investigate the formation of iodinated disinfection by-products (iodo-DBPs) and mammalian cell cyto/genotoxicity in the presence of iodinated x-ray contrast media (ICM), chlorinated oxidants, and natural organic matter (NOM). The ICM chosen as the source of iodide for these experiments were iopamidol and iohexol. The experiments were conducted with aqueous chlorine or monochloramine as the chlorinated oxidant. The experiments were conducted at pH 6.5 - 9.0. The NOM concentration was constant [DOC] = 5.57 mg/L. Chloroform formation in the presence of iopamidol, a regulated DBP, was highest at pH 9.0 with aqueous chlorine (up to 4014 nM) and pH 6.5 with monochloramine (up to 56 nM). Additionally, dichloroiodomethane followed a similar trend in the presence of iopamidol with concentrations in the chlorine experiments forming up to 650 nM and the monochloramine experiments forming up to 52 nM. Trichloroacetic acid (TCAA) formation generally decreased as pH increased; however, iopamidol significantly contributes to TCAA formation at pH 7.5 disrupting the normally observed TCAA formation trend in the presence of NOM. Toxicity of the iopamidol transformation in the presence of chlorinated oxidants and NOM was also investigated. The cytotoxicity index (CTI) values were highest for chlorine (i.e., 21.0) and monochloramine (i.e., 16.5) when compared to control experiments without iopamidol. Genotoxicity index (GTI) values were highest for chlorine (i.e., 7.1) and monochloramine (i.e., 3.5) when compared to control experiments. Iohexol DBP experiments resulted in an enhanced formation of chloroform, while very little dichloroiodomethane formed, and the TCAA formation observed was comparable to the chlorinated source water controls. With iohexol as the iodide source, the CTI and GIT values were highest with aqueous chlorine at 21.6 and 3.8, respectively, when compared to control experiments without iohexol present. Iopamidol acts as a precursor to DBP formation, while also enhancing mammalian cell cytotoxicity and genotoxicity after chlorine or chloramine disinfection. While iohexol formed regulated and unregulated DBPs, it also enhanced mammalian cell cytotoxicity and genotoxicity, though to a lesser extent than iopamidol.

Book Synopsis Some Drinking-water Disinfectants and Contaminants, Including Arsenic by : IARC Working Group on the Evaluation of Carcinogenic Risks to Humans
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.

Book Synopsis Disinfection By-Products and Human Health by : Steve E. Hrudey
Download or read book Disinfection By-Products and Human Health written by Steve E. Hrudey and published by IWA Publishing. This book was released on 2012-04-30 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Disinfection By-Products and Human Health is based on contributions from speakers who participated in May 2011 workshops on Disinfection By-Products (DBPs) and Human Health at Ozwater 11 in Adelaide, Australia or at an AWA sponsored workshop at the Curtin Water Quality Research Centre, Perth, Australia. The contributions are prepared to facilitate communication with practitioners, rather than researchers, making use of overview illustrations rather than dense text or data tables. Each chapter concludes with up to 5 key findings that are take-home messages for practitioners. Disinfection By-Products and Human Health is aimed specifically at drinking water professionals (engineers, chemists and public health professionals) working on the front lines of drinking water issues where they must encounter actual day-to-day issues of risk management concerning DBPs in relation to all the other regulatory and water quality issues they must manage. Although a topic this complex is certainly not amenable to simplistic explanations, this book aims to provide drinking water professionals with a pragmatic assessment of the current evidence and emerging issues concerning DBPs and public health. Disinfection By-Products and Human Health is an essential, practical and accessible guide for drinking water professionals, engineers, chemists and public health professionals. Editors: Steve E. Hrudey, Professor Emeritus, Analytical & Environmental Toxicology, University of Alberta, Canada, Jeffrey W.A.

Book Synopsis Analysis and Formation of Disinfection Byproducts in Drinking Water by :
Download or read book Analysis and Formation of Disinfection Byproducts in Drinking Water written by and published by Elsevier. This book was released on 2021-04-01 with total page 180 pages. 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
