A case of fatal trichlorfon and methidathion poisoning
Legal Medicine, 2002A 50-year-old man, suspected of ingesting organophosphorus insecticides, was found dead in a graveyard. In the gas chromatography-mass spectrometric screening, trichlorfon and methidathion were detected in his gastric contents. The quantitative analysis for trichlorfon and methidathion was carried out by high-performance liquid chromatography.

Bioconcentration of trichlorfon insecticide in pacu (Piaractus mesopotamicus)
Chemosphere, 2006Pacu (Piaractus mesopotamicus) is one of the most representative fish species of Brazilian fish culture, produced in most Brazilian States due to its importance for food diet and sport fishery. This research work investigated the bioconcentration of trichlorfon [phosphonic acid, (2,2,2-trichloro-1-hydroxyethyl)-dimethyl ester] insecticide in pacu under

Trichlorfon: a Selective Insecticide for Lowbush Blueberry
Journal of Economic Entomology, 1978Excellent control of the blueberry flea beetle, Altica sylvia Malloch, a casebeetle, Neochlamisus cribripennis (LeConte), a spanworm, Itame argillaceria Packard, and 2 sawflies, Neopareophora litura Klug and Pristiphora sp., was obtained on Vaccinium angustifolium Ait. with a single application of trichlorlon at 1 kg AI/ha. There was no apparent affect

Indirect polarographic determination of trichlorfon and dichlorvos
Zeitschrift für Lebensmittel-Untersuchung und -Forschung, 1974A method of indirect polarographic determination of trichlorfou and dichlorvos was elaborated. Glyoxal, the product of alkaline hydrolysis of both these organophosphorus insecticides, condenses with o-phenylendiamine to forming quinoxaline, which is polarographically reduced, giving a well-developed two-electron wave.

Prenatal effects of trichlorfon on the guinea pig brain
Archives of Toxicology, 1986The organophosphorus compound trichlorfon, dimethyl (2,2,2-trichloro-1-hydroxyethyl) phosphonate, was administered by stomach tube (100 mg/kg) to pregnant guinea pigs at two different stages of gestation (days 36, 37, 38 and 51, 52, 53). The pups developed locomotory disturbances, and post mortem examination revealed significantly decreased weights of ...

MICROWAVE SYNTHESIS OF TRICHLORFON AND ITS ANALOGUES
Phosphorus, Sulfur, and Silicon and the Related Elements, 2004The synthesis of dialkyl-(2,2,2-trichloro-1-Hydroxyethyl) phosphonates using dialkyl hydrogen phosphite and chloral hydrate under solvent-free condition by microwave irradiation is reported. The products were chrachetrized using 1 H NMR, 13 C NMR, and 31 P NMR spectroscopy.

Trichlorfon exposure, spindle aberrations and nondisjunction in mammalian oocytes
Chromosoma, 1998Consumption of trichlorfon-poisoned fish by women in a small Hungarian village has been associated with trisomy resulting from an error of meiosis II in oogenesis. We therefore examined mouse oocytes exposed for 3 h during fertilization to 50 microg/ml trichlorfon. Spindle morphology was not visibly altered by the pesticide.

Hepatotoxicity of trichlorfon and dichlorvos in isolated rat hepatocytes
Toxicology, 1992Hepatotoxicity of organophosphorus insecticides, trichlorofon and dichlorvos, a dechlorinated form of the former, was examined in isolated hepatocytes from untreated control and phenobarbital-pretreated (80 mg/kg, i.p., for 3 days) rats. These compounds produced toxic effects on hepatocytes as evidenced by malondialdehyde production and lactate ...

Trichlorfon effects on mouse oocytes following in vivo exposure
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2008Trichlorfon (TCF) is a widely used pesticide, which according to some epidemiological and experimental data, is suspected of being aneugenic in human and mouse cells. In particular, in vitro studies in mouse oocytes showed the induction of aneuploidy and polyploidy at the first meiotic division and of severe morphological alterations of the second ...

Genotoxic activity of dichlorvos, trichlorfon and dichloroacetaldehyde
Pesticide Science, 1984AbstractTwo structurally related organophosphorous insecticides, dichlorvos and trichlorfon, and their main metabolite dichloroacetaldehyde, were assayed for their ability to induce DNA repair, detected as unscheduled DNA synthesis in human epithelial‐like cell (EUE) cultures in vitro.
