Comparative Cytotoxicity and Genotoxicity of Drinking Water Disinfection by -Products
… cells. The difference in the responses to DBPs by bacterial and mammalian cells suggests that the relative risks based on Salmonella alone should be questioned. The in vitro microplate based bacterial and mammalian assays developed and used in this research can be employed for screening other …

Drinking water disinfection by-products detection, formation and the precursors removal study
… (THMs) are two groups of commonly found disinfection by-products (DBPs). Iodinated THMs and HAAs were observed after disinfection of water containing high level of iodide and are proved to be more toxic than their corresponding chlorinated and brominated species. In the presented …

Quantitative, Comparative Toxicity and Toxicogenomic Analyses of Nitrogenous Drinking Water Disinfection by-Products
The disinfection of drinking water was perhaps the most important public health achievement of the 20th century. Drinking water disinfection by-products (DBPs) are an unintended consequence of a chemical reaction between natural and synthetic organic/inorganic materials in the source water and the …

Drinking water disinfection by-products: toxicological impacts and biological mechanisms induced by individual compounds or as complex mixtures
The introduction of drinking water disinfection greatly reduced the incidence of waterborne diseases. However, the reaction between disinfectants and natural or synthetic organic matter in the source water can lead to an unintended consequence which is the formation of drinking water disinfection …

Toxicity mechanism of anthropogenic water contaminants: drinking water disinfection by-products (haloacetic acids) and particle associated contaminants from sealcoats (polyaromatic hydrocarbons) in lake sediments
Drinking water disinfection was one of the major public health accomplishments of 20th century. Water disinfection helps in reducing waterborne diseases like typhoid fever, cholera, and hepatitis A. However, chemical water disinfection also produces unwanted toxic chemicals, known as water …

Analysis of disinfection by products in drinking water by solid phase extraction
… concentration, and analysis of drinking water disinfection by products using solid phase extraction (SPE), and to determine if this method had lower detection limits and less variability than the proposed liquid-liquid extraction method, EPA Method 551. The disinfection by products …

Analysis and occurrence of disinfection by-products in fresh and salt water
… trihalomethanes, and bromate are important toxic water disinfection by-products (DBPs) that the US Environmental Protection Agency (USEPA) regulates in drinking water. Iodoacetic acids and halonitromethanes (HNMs) are the unregulated emerging DBPs that have been recently found in the disinfected …

Development and application of fractionation procedure for drinking water organic matters
USEPA mandates a control of disinfection by-products (DBPs) in finished drinking water and recommends reduction of natural organic matters (NOM), DBP precursors, to achieve this regulatory goal. Studies relating NOM with DBP include fractionation of water samples, characterization of collected …
