Disinfection By-products: A Question of Balance [PDF]

Environmental Health Perspectives, 2010
By all accounts, disinfection of drinking water is one of the major public health triumphs of the 20th century. No human endeavor, however, is without risk; more than 30 years ago it was determined that chlorination of water resulted in formation of disinfection by-products (DBPs).

Assessment of drinking water treatment and disinfection by-products

South African Journal of Chemical Engineering, 2022
Water treatment plants and disinfection by-products are a worldwide problem in the provision of drinking water with disinfectants. However, in countries like Ethiopia, studies on the condition of water treatment plants and the risks they pose are scarce.

Trihalomethanes Formation Potential in Water Supply System of Bandar Abbas (Southern Iran): from Source to Distribution Network [PDF]

Journal of Health Sciences and Surveillance System, 2014
Background: Pre-chlorination of raw water containing natural organic matters may lead to forming harmful disinfection by-products such as trihalomethanes (THMs), the measurement of which needs expensive advanced analytical instruments.

Chlorine dioxide drinking water pre-oxidation and disinfection: A review of its effectiveness, mechanisms, and disinfection by-products

Desalination and Water Treatment
Effective drinking water disinfection requires robust microbial inactivation with minimal disinfection by-product (DBP) formation. Chlorine dioxide (ClO2), a potential alternative to chlorine (Cl2), has gained significant attention in this context.

The alkaline comet assay used in evaluation of genotoxic damage of drinking water disinfection by-products (bromoform and chloroform)

Frontiers in Genetics, 2015
The alkaline comet assay (pH 12.3) is a useful method for monitoring genotoxic effects of environmental pollutants in the root nuclei of Allium cepa and various plants; it allows the detection of single- and double-strand breaks, incomplete excision ...

Trimester-specific associations of maternal exposure to disinfection by-products, oxidative stress, and neonatal neurobehavioral development

Environment International, 2021
Background: Toxicological studies suggest that maternal exposure to disinfection by-products (DBPs) can impair fetal neurodevelopment. However, evidence from epidemiological studies is scarce and the underlying mechanisms remain unclear.
