Simultaneous liquid-liquid microextraction/methylation for the determination of haloacetic acids in drinking waters by headspace gas chromatography.
J. Chromatogr. A. 1209(1-2) , 61-9, (2008) 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 ... |

Mammalian cell cytotoxicity and genotoxicity of the haloacetic acids, a major class of drinking water disinfection by-products.
Environ. Mol. Mutagen. 51(8-9) , 871-8, (2010) 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 (CA... |

Phase III interlaboratory study of FETAX. Part 3. FETAX validation using 12 compounds with and without an exogenous metabolic activation system.
J. Appl. Toxicol. 19(6) , 447-72, (1999) FETAX (Frog Embryo Teratogenesis Assay-Xenopus) is a 96-h whole-embryo developmental toxicity screening assay that can be used in ecotoxicology and in detecting mammalian developmental toxicants when an in vitro metabolic activation system is employed. A stan... |

Haloalkanoate dehalogenase II (DehE) of a Rhizobium sp.--molecular analysis of the gene and formation of carbon monoxide from trihaloacetate by the enzyme.
Eur. J. Biochem. 250(3) , 789-93, (1997) A 3-kb EcoRI fragment of genomic DNA from a Rhizobium sp. cloned into pUC19 endowed Escherichia coli K-12 with the ability to grow, albeit slowly, with 2-chloropropionic acid as substrate. The construct expressed weakly a gene that encoded a non-stereospecifi... |

Halogenated derivatives QSAR model using spectral moments to predict haloacetic acids (HAA) mutagenicity.
Bioorg. Med. Chem. 16 , 5720-32, (2008) 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 these... |
