Trihalomethane Levels and Their Seasonal Variation in Drinking Water Produced from Thermal Desalination in Kuwait

Drinking water is obtained in Kuwait by blending desalinated seawater with 5–10% brackish water. Chemical analysis of trihalomethanes (THMs) was performed on 624 water samples collected from private residences and government buildings from December 2003 to May 2005. The highest value recorded (91.01 g/L), exceeds the maximum contaminant level (MCL) set by the U.S. EPA. Significant variations in...

Trihalomethane Removal and Formation Mechanism in Water

Drinking water and pregnancy outcome in central North Carolina: source, amount, and trihalomethane levels.

In spite of the recognition of potentially toxic chemicals in chlorinated drinking water, few studies have evaluated reproductive health consequences of such exposure. Using data from a case-control study of miscarriage, preterm delivery, and low birth weight in central North Carolina, we evaluated risk associated with water source, amount, and trihalomethane (THM) concentration. Water source w...

Trihalomethane Removal from Water Using Membrane Processes

Trihalomethanes (THMs) are formed due to chlorination of water containing organic compounds. They have mutagenous and carcinogenic properties. The main representative of this effluent group is chloroform. The objectives of this paper are to determine the removal effectiveness of chloroform from natural water with the application of reverse osmosis, nanofiltration and ultrafiltration as well as ...

DNA methylation levels and long-term trihalomethane exposure in drinking water: an epigenome-wide association study.

Trihalomethanes (THM) are undesired disinfection byproducts (DBPs) formed during water treatment. Mice exposed to DBPs showed global DNA hypomethylation and c-myc and c-jun gene-specific hypomethylation, while evidence of epigenetic effects in humans is scarce. We explored the association between lifetime THM exposure and DNA methylation through an epigenome-wide association study. We selected ...
