Trichloroacetate (TCA), dichloroacetate (DCA), and bromodichloroacetate (BDCA) are byproducts of the chlorination of drinking water. TCA acts primarily as a peroxisome proliferator, but DCA produces tumors at doses less than required for peroxisome proliferation. BDCA does not induce peroxisome proliferation

This study aimed to compare the toxicity reduction performance of conventional drinking water treatment (CT) and a treatment (NT) with quaternized magnetic microspheres (NDMP) based on chemical analyses. Fluorescence excitation-emission-matrix combined with parallel factor analysis identified four components in source

The risk of the presence of haloacetic acids in drinking water as chlorination by-products and the shortage of experimental mutagenicity data for most of them requires a research work. This paper describes a QSAR model to predict direct mutagenicity for

Disinfection by-products and perchlorate in the raw water and finished water of Beijing's a drinking water plants were investigated. The results indicated that there was little bromate in the drinking water. Five haloacetic acids (HAAs) were found in the water.

This study determined the metabolism of 3 drinking water disinfection by-products (halogenated acetic acids [HAAs]), bromodichloroacetic acid (BDCAA), chlorodibromoacetic acid (CDBAA), and tribromoacetic acid (TBAA), using rat, mouse, human liver microsomes, and recombinant P450. Metabolism proceeded by reductive debromination forming

The haloacetic acids (HAA) are a family of chemicals that are drinking water disinfection by-products. We previously reported that haloacetic acids, including several bromo- and chloro-HAAs, alter embryonic development when mouse conceptuses are directly exposed to these xenobiotics in whole

The microextraction/ion chromatographic (IC) method developed in this study involves extraction of 9 haloacetic acids (HAAs) from aqueous samples (acidified with sulfuric acid to a pH of < 0.5 and amended with copper sulfate pentahydrate and sodium sulfate) with methyl

A novel analytical method that combines simultaneous liquid-liquid microextraction/methylation and headspace gas chromatography-mass spectrometry for the determination of nine haloacetic acids (HAAs) in water was reported. A mechanistic model on the basis of mass transfer with chemical reaction in which

Haloacetic acids (HAAs) are a group of disinfection by-products formed in chlorinated water. Due to their potential health effects and widespread occurrences, HAAs are regulated in drinking water in the United States under a promulgated regulation. To better control the

The purpose of this study is to investigate the changes of concentration of trihalomethanes (THMs: chloroform, bromodichloromethane, chlorodibromomethane, bromoform) and haloacetic acids (HAAs: monochloroacetic acid, monobromoacetic acid, dichloroacetic acid, dibromoacetic acid, trichloroacetic acid, bromochloroacetic acid) in water samples with holding

Haloacetates are a common class of water chlorination by-products. Depending on the amount of bromide in the source water, varying amounts of chlorinated, brominated, and mixed bromochloro haloacetates are produced. When administered to rodents, haloacetates have been shown to increase

The oral and i.v. elimination kinetics were investigated for bromodichloroacetate (BDCA), a haloacetate found in drinking water. The BDCA was administered at a dose of 5, 20 and 100 mg kg-1 to B6C3F1 mice and appears to distribute to the

The haloacetic acids (HAAs) are disinfection by-products (DBPs) that are formed during the disinfection of drinking water, wastewaters and recreational pool waters. Currently, five HAAs [bromoacetic acid (BAA), dibromoacetic acid (DBAA), chloroacetic acid (CAA), dichloroacetic acid (DCAA), and trichloroacetic acid
