Occurrence and control of nitrogenous disinfection by-products in drinking water--a review.
TLDR
A critical review of the occurrence and control of nitrogenous disinfection by-products is provided, finding that the sum of analysed halonitromethanes represented 3-4% of the mass of THMs on a median basis.About:

Halonitroalkanes, Halonitriles, Haloamides, and N-Nitrosamines: A Critical Review of Nitrogenous Disinfection Byproduct Formation Pathways
Amisha D. Shah,William A. Mitch +1 more
TL;DR: In this article, the formation pathways for nitrogenous disinfection byproducts (N-DBPs) associated with chlorine, ozone, chlorine dioxide, UV, and chloramine disinfection are critically reviewed.
Journal ArticleDOI
Formation, precursors, control, and occurrence of nitrosamines in drinking water: a review.
TL;DR: This review summarizes major findings over the last decade related to nitrosamines in drinking water, with a particular focus on N-nitrosodimethylamine (NDMA), because it is among the most widely detected nitrosamine in drinking waters.
Journal ArticleDOI
Precursors of nitrogenous disinfection by-products in drinking water--a critical review and analysis
TL;DR: It was calculated that for HANs and HAcAms, the concentrations of known precursors - mainly free amino acids are insufficient to account for the observed concentrations of these N-DBP groups, however, at least in some waters, a significant proportion of CNX and NDMA formation can be explained by known precurors.
Journal ArticleDOI
Comparison of Permanganate Preoxidation and Preozonation on Algae Containing Water: Cell Integrity, Characteristics, and Chlorinated Disinfection Byproduct Formation
TL;DR: The results suggest that permanganate is a better choice than ozone for controlling algae derived pollutants and disinfection byproducts after preozonation.

Recent developments in environmental photocatalytic degradation of organic pollutants: the case of titanium dioxide nanoparticles—a review
TL;DR: In this paper, the authors explore and summarize recent efforts in the area of titania nanoparticle synthesis, modifications, and application for water treatment purposes, and conclude that Titania nanoparticles are intended to be both supplementary and complementary to the present water treatment technologies through the destruction or transformation of hazardous chemical wastes to innocuous end-products, that is, CO2 and H2O.

Formation of N-nitrosodimethylamine (NDMA) from reaction of monochloramine: a new disinfection by-product
TL;DR: It is concluded that reactions involving monochloramine in addition to classical nitrosation reactions are potentially important pathways for NDMA formation.
Journal ArticleDOI
Chlorination disinfection by-products, public health risk tradeoffs and me.
TL;DR: There are now more than 30 years of drinking water quality, treatment and health effects research, including more than 60 epidemiology studies on human populations, directed at the chlorination DBP issue, providing considerable scope to reflect on what the authors know now, how their understanding has changed, what those changes mean for public health risk management overall and where they should look to better understand and manage this issue in the future.
Journal ArticleDOI
Mammalian cell cytotoxicity and genotoxicity analysis of drinking water disinfection by-products.
TL;DR: The microplate CHO cell cytotoxicity and genotoxicity assays were well suited for the analysis of DBPs, especially when the quantity of test material is limited, and it was determined that the DBP genotoxic potency in CHO cells and the mutagenic potency in S. typhimurium were not related.
Journal ArticleDOI
Occurrence of disinfection byproducts in United States wastewater treatment plant effluents.
TL;DR: Because of the relatively high levels of bromide in treated wastewater, bromine incorporation was observed in various classes of DBPs.

Dissolved organic nitrogen in drinking water supplies: a review
Paul Westerhoff,Heath Mash +1 more
TL;DR: In this article, the authors present an analytical measurement of dissolved organic nitrogen (Don) in the water field, which is calculated by the difference between total dissolved nitrogen and inorganic nitrogen ions.
