Environmentally relevant mixing ratios in cumulative assessments: a study of the kinetics of pyrethroids and their ester cleavage metabolites in blood and brain; and the effect of a pyrethroid mixture on the motor activity of rats.
Toxicology 320 , 15-24, (2014) National surveys of United States households and child care centers have demonstrated that pyrethroids are widely distributed in indoor habited dwellings and this suggests that co-exposure to multiple pyrethroids occurs in nonoccupational settings. The purpos... |

[Chemical toxicological identification of esfenvalerate].
Sud. Med. Ekspert. 55(3) , 37-41, (2012) The optimal conditions for the isolation of esfenvalerate from the biological specimens have been determined. It was shown that this compound can be separated from the endogenous component of a biological material by means of liquid-liquid extraction and chro... |

Pyrethroids in human breast milk: occurrence and nursing daily intake estimation.
Environ. Int. 47 , 17-22, (2012) There is an assumption that pyrethroid pesticides are converted to non-toxic metabolites by hydrolysis in mammals. However, some recent works have shown their bioaccumulation in human breast milk collected in areas where pyrethroids have been widely used for ... |

Kinetic and product study of the heterogeneous reactions of NO3 radicals with suspended resmethrin, phenothrin, and fenvalerate particles.
Chemosphere 90(2) , 848-55, (2013) Resmethrin, phenothrin, and fenvalerate are the synthetic pyrethroids that have been used widely against groundling or flying insect pests both indoors and outdoors. In this study, the heterogeneous reactions of the three pyrethroid particles with NO(3) radic... |

Children's exposures to pyrethroid insecticides at home: a review of data collected in published exposure measurement studies conducted in the United States.
Int. J. Environ. Res. Public Health 9 , 2964-85, (2012) Pyrethroid insecticides are frequently used to control insects in residential and agriculture settings in the United States and worldwide. As a result, children can be potentially exposed to pyrethroid residues in food and at home. This review summarizes data... |

Spectroscopic studies on the photochemical decarboxylation mechanisms of synthetic pyrethroids.
Photochem. Photobiol. Sci. 11(12) , 1897-904, (2012) A novel radical trapping technique combined with a fluorescence spectroscopic analysis has been employed to investigate the radical intermediates produced by photodecarboxylation of four synthetic pyrethroids: fenvalerate (SMD), fenpropathrin (DTL), cyphenoth... |

Current status of insecticide resistance in Helicoverpa armigera after 15 years of Bt cotton planting in China.
J. Econ. Entomol. 106(1) , 375-81, (2013) Insecticide resistance was an important factor responsible for outbreaks of Helicoverpa armigera (Hübner) in China in the early 1990s. Bt cotton has been adopted in China since 1997, and has resulted in a reduction of insecticide use for H. armigera control. ... |

Impact of insecticide and fungicide residue contact on plum curculio, Conotrachelus nenuphar (Herbst), mobility and mortality: implications for pest management.
Pest Manag. Sci. 69 , 464-70, (2013) An evaluation was made of the effects of seven neurotoxic insecticides (esfenvalerate, indoxacarb, clothianidin, thiacloprid, azinphosmethyl, phosmet and imidacloprid), one insect growth regulator (novaluron) and two fungicides (myclobutanin and mancozeb), wi... |

Intraspecific competition increases toxicant effects in outdoor pond microcosms.
Ecotoxicology 21(7) , 1857-66, (2012) Competition is a ubiquitous factor in natural populations and has been reported to alter the ecological impact of xenobiotics. We investigated conditions that mirror the natural variation of environmental factors. For this, different treatments were applied t... |
