Disinfection Byproducts and Bladder Cancer

Epidemiology, 2004
Exposure to disinfection byproducts in drinking water has been associated with an increased risk of bladder cancer. We pooled the primary data from 6 case-control studies of bladder cancer that used trihalomethanes as a marker of disinfection byproducts.Two studies were included from the United States and one each from Canada, France, Italy, and ...

Comparison of disinfection byproduct formation from chlorine and alternative disinfectants

Water Research, 2007
Seven diverse natural waters were collected and treated in the laboratory under five oxidation scenarios (chlorine, chloramine, both with and without preozonation, and chlorine dioxide). The impact of these disinfectants on the formation of disinfection byproducts was investigated.

Genotoxicity of disinfection byproducts and disinfected waters: A review of recent literature

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2018
The presence of water disinfection byproducts (DBPs) in tap water, resulting from disinfection processes involving chlorination or chloramination, increases the mutagenicity of the water and may pose adverse health effects. The topic was reviewed by DeMarini and coworkers in 2007.

Stormwater Discharge: An Overlooked Source of Disinfection Byproducts Precursors

Journal of Hazardous Materials, 2023
Discharge from the stormwater system is as an important pathway for contaminant transport, impacting the quantity and characteristics of dissolved organic matter (DOM) in surface water, and thus the formation of disinfection byproducts (DBPs) during downstream drinking water disinfection. In this study, DOM in stormwater pipes was characterized by size-

Increase Disinfectant Residual While Reducing Disinfection Byproducts

Opflow, 2021
The relationship between the amount of disinfectant residual and disinfection byproducts measured in finished water poses a challenge for water treatment and distribution operators. Central Arkansas Water investigated how to effectively reduce microbial and chemical contaminants.

Nonadditive Cytotoxicity in Select Disinfection Byproducts and Disinfected Secondary Effluents

Environmental Science & Technology
Toxicity studies of water disinfection byproducts (DBPs) typically assume additive interactions. Coupling results from both the bottom-up cytotoxicity interaction approach by selecting six common DBPs and the top-down cytotoxicity fractionating the disinfected secondary effluent containing a much broader DBP selection, we demonstrated a novel effect of

Degradation of Disinfection Byproducts by Carbonate Green Rust

Environmental Science & Technology, 2007
Disinfection byproducts (DBPs) in drinking water flowing through corroded iron or steel pipes may encounter carbonate green rust (GR(CO32-)), a mixed Fe(II)/Fe(lll) hydroxide mineral and potent reductant. This research was performed to investigate the kinetics and pathways of the degradation of selected halogenated DBPs in the presence of GR(C032 ...

Nontargeted identification of peptides and disinfection byproducts in water

Journal of Environmental Sciences, 2016
A broad range of organic compounds are known to exist in drinking water sources and serve as precursors of disinfection byproducts (DBPs). Epidemiological findings of an association of increased risk of bladder cancer with the consumption of chlorinated water has resulted in health concerns about DBPs.

Restored Wetlands as a Source of Disinfection Byproduct Precursors

Environmental Science & Technology, 2008
The effects of a restored wetland system in the Sacramento Valley, California on the production of dissolved organic carbon (DOC) and nitrogen (DON) and the formation potential of common disinfection byproducts (DBPs: trihalomethanes, haloacetonitriles, and chloral hydrate) were examined.
