A survey of disinfection byproduct (DBP) occurrence in the United States was conducted at 12 drinking water treatment plants. In addition to currently regulated DBPs, more than 50 DBPs that rated a high priority for potential toxicity were studied. These included iodinated trihalomethanes (THMs), other halomethanes, nonregulated haloacid, haloacetonitriles, haloketones, halonitromethanes, haloaldehydes, halogenated furanones, haloamides, and nonhalogenated carbonyls. The purpose this study...
Haloacetonitriles (HANs) are toxic nitrogenous drinking water disinfection byproducts (N-DBPs) and observed with chlorine, chloramine, or chlorine dioxide disinfection. Using microplate-based Chinese hamster ovary (CHO) cell assays for chronic cytotoxicity acute genotoxicity, we analyzed 7 HANs: iodoacetonitrile (IAN), bromoacetonitrile (BAN), dibromoacetonitrile (DBAN), bromochloroacetonitrile (BCAN), chloroacetonitrile (CAN), dichloroacetonitrile (DCAN), trichloroacetonitrile (TCAN). The...
An occurrence study was conducted to measure five iodo-acids (iodoacetic acid, bromoiodoacetic (Z)-3-bromo-3-iodo-propenoic (E)-3-bromo-3-iodo-propenoic and (E)-2-iodo-3-methylbutenedioic acid) two iodo-trihalomethanes (iodo-THMs), (dichloroiodomethane bromochloroiodomethane) in chloraminated chlorinated drinking waters from 23 cities the United States Canada. Since iodoacetic acid previouslyfound be genotoxic mammalian cells, iodo-THMs were analyzed for toxicity. A gas chromatography...

Halonitromethanes are drinking water disinfection byproducts that have recently received a high priority for health effects research from the U.S. Environmental Protection Agency (EPA). Our purpose was to identify and synthesize where necessary mixed halonitromethanes determine chronic cytotoxicity acute genotoxicity of these agents in mammalian cells. The included bromonitromethane (BNM), dibromonitromethane (DBNM), tribromonitromethane (TBNM), bromochloronitromethane (BCNM),...
Iodoacid drinking water disinfection byproducts (DBPs) were recently uncovered in samples from source with a high bromide/iodide concentration that was disinfected chloramines. The purpose of this paper is to report the analytical chemical identification iodoacetic acid (IA) and other iodoacids samples, address cytotoxicity genotoxicity IA Salmonella typhimurium mammalian cells, structure−function analysis its chlorinated brominated monohalogenated analogues. iodoacid DBPs identified as...

The haloacetic acids (HAAs) are disinfection by-products (DBPs) that formed during the of drinking water, wastewaters and recreational pool waters. Currently, five HAAs [bromoacetic acid (BAA), dibromoacetic (DBAA), chloroacetic (CAA), dichloroacetic (DCAA), trichloroacetic (TCAA); designated as HAA5] regulated by U.S. EPA, at a maximum contaminant level 60 μg/L for sum BAA, DBAA, CAA, DCAA, TCAA. We present comparative systematic analysis chronic cytotoxicity acute genomic DNA damaging...
Iodinated X-ray contrast media (ICM) were investigated as a source of iodine in the formation iodo-trihalomethane (iodo-THM) and iodo-acid disinfection byproducts (DBPs), both which are highly genotoxic and/or cytotoxic mammalian cells. ICM widely used at medical centers to enable imaging soft tissues (e.g., organs, veins, blood vessels) designed be inert substances, with 95% eliminated urine feces unmetabolized within 24 h. not well removed wastewater treatment plants, such that they have...
