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 ...

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.

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.

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.

Pathways of trihalomethane uptake in swimming pools

International Journal of Hygiene and Environmental Health, 2004
Chlorination of pool water leads to the formation of numerous disinfection by-products (DBPs), chloroform usually being most abundant. Bathers and pool guardians take up various amounts of DBPs by different pathways. Identification of different uptake paths is important in order to develop a technical strategy for swimming pool water treatment and to ...

The occurrence of trihalomethanes in the drinking water in Greece

Chemosphere, 2000
This paper summarizes and completes an investigation into the occurrence of trihalomethanes (THMs) in public water supplies in Greece. The investigation was conducted in three cities of Greece, Athens, Mytilene and Chalkida, from 1993 to 1998. Samples were collected from three treatment plants of Athens (Galatsi Treatment Plant--GTP, Menidi Treatment ...

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 ...
