A field outbreak of suspected poisoning is recorded from feed medicated with the organophosphorus insecticide trichlorfon. A controlled experiment showed that toxicity could occur when trichlorfon was fed from 3-5 days at levels greater than that recommended. Signs recorded were inappetence, muscle tremor, ataxia and deaths.

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

Enantioseparation and enantioselective behavior of trichlorfon enantiomers in sediments
Chirality, 2017AbstractTrichlorfon (TF), an organophosphorus insecticide, has been widely used in seawater aquaculture; it is easily degraded to the highly toxic insecticide, dichlorvos (DDVP). In this study, the enantioseparation of TF enantiomers, as well as their degradation behavior and product (DDVP) formation in mariculture pond sediments, was investigated. The

Distribution and placental transfer of trichlorfon in guinea pigs
Archives of Toxicology, 1986Radiolabelled trichlorfon, dimethyl-(2,2,2-trichloro-1-hydroxyethyl)phosphonate, was administered by stomach tube to pregnant guinea pigs on days 37 and 52 of gestation and examined by the whole body autoradiography method. The results showed that the radiolabelled compound was rapidly distributed to the main organs of the dam with the highest ...

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 ...

Assessment of teratogenic potential of trichlorfon in mice and rats
Journal of Environmental Science and Health, Part B, 1986Trichlorfon was evaluated for its teratogenic potential in the CD-1 mouse at doses of 200, 300 or 400 mg/kg/day administered by gavage on days 7-16 of gestation. In the CD-1 mouse, TCF was teratogenic, fetotoxic and lethal at the two highest dose levels which were also maternally lethal.

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: 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.

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.
