Trihalomethanes in Drinking Water and Spontaneous Abortion

Epidemiology, 1998
Trihalomethanes (chloroform, bromoform, bromodichloromethane, and chlorodibromomethane) are common contaminants of chlorinated drinking water. Although animal data indicate that these compounds may be reproductive toxicants, little information exists on their relation to spontaneous abortion in humans.

Formation of Trihalomethanes by Chlorination of Surface Water

Environmental Letters, 1975
Chloroform, bromodichloromethane, dibromochloromethane, bromoform, and dichloroiodomethane have been found in chlorinated drinking water. In addition to these five compounds, the other possible trihalomethanes (chlorodiiodomethane, bromochloroiodomethane, dibromoiodomethane, bromodiiodomethane, and iodoform) can also be formed by chlorination of ...

Modeling of trihalomethane cometabolism in nitrifying biofilters

Water Research, 2007
The computer program AQUASIM was used to model biofilter experiments seeded with Lake Austin, Texas mixed-culture nitrifiers. These biofilters degraded four trihalomethanes (THMs) (trichloromethane (TCM) or chloroform, bromodichloromethane (BDCM), dibromochloromethane (DBCM), tribromomethane (TBM) or bromoform) commonly found in treated drinking water.

Trihalomethanes aqueous solutions sono-oxidation

Water Research, 2005
Ultrasonic (US) irradiation, hydrogen peroxide (H(2)O(2)), Fenton's oxidation and the combination of the processes were investigated for destruction and removal of the following trihalomethanes (THMs) compounds from aqueous solutions: CHCl(3), CHBrCl(2), CHBr(2)Cl, CHBr(3), and CHI(3). H(2)O(2) had no significant effect on the THMs sonodegradation. The

Cometabolism of trihalomethanes by mixed culture nitrifiers

Water Research, 2006
Three mixed-culture nitrifier sources degraded low concentrations (25-450 microg/L) of four trihalomethanes (THMs) (trichloromethane (TCM) or chloroform, bromodichloromethane (BDCM), dibromochloromethane (DBCM), tribromomethane (TBM) or bromoform) commonly found in treated drinking water.

Determination of trihalomethanes in water samples: A review

Analytica Chimica Acta, 2008
This 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.

Levels of trihalomethanes in the blended water of Bahrain

Science of the Total Environment, 1994
The distribution of trihalomethanes in the water of the two main power stations and the 10 blending stations in Bahrain has been studied. Total trihalomethanes in the drinking water averaged 2.95 micrograms/l. Average concentrations (microgram/l) of individual compounds were: CHBr3, 2.17 +/- 0.3; CHBr2Cl, 0.48 +/- 0.14; CHBrCl2, 0.30 +/- 0.13.

Sources of variability in levels and exposure to trihalomethanes

Environmental Research, 2007
In the framework of a cohort study of pregnant women conducted in Brittany (France), we assessed the exposure to trihalomethanes (THM) during pregnancy in a subset by evaluating (1) potential sources of variability in household THM levels; (2) the between- and within-subject variability in THM levels; (3) THM levels in swimming pools; and (4) the role ...

TRIHALOMETHANE REMOVAL BY ACTIVATED CARBON FIBER

Journal of Environmental Science and Health, Part A, 2001
For the safety of drinking water, trihalomethanes are removed by adsorption onto activated carbon fiber from single-component solutions. The amounts adsorbed onto adsorbents with large surface area and/or pore volume were small. Stronger surface hydrophobicity of adsorbent was correlated with a larger amount of trihalomethanes adsorbed.

Toxicological aspects of trihalomethanes: a systematic review

Environmental Science and Pollution Research, 2019
Chlorine is considered the most used chemical agent for water disinfection worldwide. However, water chlorination can lead to by-product generation which can be toxic to humans. The present study aimed to perform a systematic review on the toxicity of trihalomethanes (THMs) through bioindicators of cytotoxicity, genotoxicity, and mutagenicity.
