Acta hydrochimica et hydrobiologica, 1987
AbstractIn three water works investigations were performed on the formation of halogenated hydrocarbons resulting from chlorination and the results are given. There were exclusively detected halogenated methane compounds with concentrations below 25 μg/1 and therefore agreeing with values already reported.

Precise Analysis of Trihalomethanes
Journal AWWA, 1979The liquid‐liquid extraction (LLE) technique yields precise and accurate analysis of trihalomethanes in drinking water. The use of glass capillary gas chromatography affords quality assurance and versatility as well as speed: a chemist can analyze eight samples per hour on one gas chromatograph.

Correlating Trihalomethane Data
Journal of Environmental Engineering, 1994Because of its importance as a drinking water supply for 20,000,000 Californians, the Sacramento‐San Joaquin delta and its tributaries have received much attention with respect to drinking water quality in general and trihalomethane formation potential (THMFP) in particular.

Catalytic Degradation of Trihalomethanes
1984Abstract : The chlorination of waters containing humic and other organic substances leads to the formation of trihalomethanes (THMS). These compounds are suspected carcinogens and pose a health hazard. Their formation and removal after chlorination is of interest to the Army because of the exclusive use of hypochlorite for disinfection.

Analysis of drinking water for the detection of trihalomethanes
Bulletin of Environmental Contamination and Toxicology, 1985Drinking water of the Dammam metropolitan area is a blend of raw well water and desalinated water obtained from the Al-Azizia seawater desalination plant. Chlorination is the only disinfection method applied to the blended water before the water is pumped into the distribution system.

Uptake of trihalomethanes by patients during hemodialysis
Clinica Chimica Acta, 1989Trihalomethanes (THM) present in tap water were also found in dialysis fluid because they were not eliminated by water treatment. THM, absorbed through the dialyser membranes, increased considerably in blood and in expired air of patients on hemodialysis during the dialysis sessions. The uptake of THM during each dialysis session was about 1 mg.

Exposure to Trihalomethanes and Adverse Pregnancy Outcomes
Epidemiology, 1998Exposure during pregnancy to disinfection by-products in drinking water has been hypothesized to lead to several adverse reproductive outcomes. We performed a retrospective cohort study to examine the relation of trihalomethane exposure during the third trimester of pregnancy to low birthweight, term low birthweight, and preterm delivery.

Comparison of Trihalomethanes in Tap Water and Blood
Environmental Science & Technology, 2002Trihalomethane (THM) concentrations in blood and tap water were measured for 50 women living in two locations with different bromide concentrations and disinfectant types. Blood samples were taken from each woman early in the morning prior to any major water-use activity and again immediately after showering.

Determination of trihalomethanes in water samples: A review
Analytica Chimica Acta, 2008This article reviews the most recent literature addressing the analytical methods applied for trihalomethanes (THMs) determination in water samples. This analysis is usually performed with gas chromatography (GC) combined with a preconcentration step.
