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... |

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... |

Chemical and bioanalytical assessments on drinking water treatments by quaternized magnetic microspheres.
J. Hazard. Mater. 285 , 53-60, (2015) 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 p... |

Exposure to mutagenic disinfection byproducts leads to increase of antibiotic resistance in Pseudomonas aeruginosa.
Environ. Sci. Technol. 48(14) , 8188-95, (2014) Bacterial antibiotic resistance (BAR) in drinking water has become a global issue because of its risks on the public health. Usually, the antibiotic concentrations in drinking water are too low to select antibiotic resistant strains effectively, suggesting th... |

Short-term exposures to dihaloacetic acids produce dysmorphogenesis in mouse conceptuses in vitro.
Reprod. Toxicol. 22(3) , 443-8, (2006) The haloacetic acids (HAAs) are a family of xenobiotics found in tap water as a result of drinking water disinfection. Administration of HAAs to rats produces a variety of adverse effects, including developmental toxicity. The dysmorphogenic potencies of all ... |

Evaluation of the effects of water disinfection by-products, bromochloroacetic and dibromoacetic acids, on frog embryogenesis.
J. Toxicol. Environ. Health A 67(12) , 929-39, (2004) Adverse developmental effects of two haloacetic acids, bromochloroacetic acid (BCA) and dibromoacetic acid (DBA), were determined by using the Frog Embryo Teratogenesis Assay--Xenopus (FETAX). Xenopus embryos (150-400/concentration group) were exposed to 0, 8... |

Determination of ten haloacetic acids in drinking water using high-performance and ultra-performance liquid chromatography-tandem mass spectrometry.
J. Chromatogr. Sci. 47(1) , 67-74, (2009) Haloacetic acids (HAAs) are a class of byproducts resulting from the reaction of chlorinated disinfectants with natural organic matter. These chemicals have been found in animal studies to possibly influence hepatic, reproductive, and developmental functions,... |
