Tetrachlorvinphos Chemical Properties,Uses,Production
Description
Tetrachlorvinphos was initially registered for use in the United States in 1966 for use on various food crops, livestock, and pet animals, and in around buildings. Its use on food crops were voluntarily canceled in the United States in 1987; however, it is used on food crops in developing countries. Tetrachlorvinphos is sold under the trade names Rabon and Gardona.
Chemical Properties
Technical tetrachlorvinphos is a tan-to-brown crystalline
solid. Tetrachlorvinphos is stable at ,100 C and slowly
hydrolyzed at 50°C. Aromatic odor.
Soluble in water at 24°C 15 ppm; limited
solubility in most aromatic hydrocarbons.
Uses
Tetrachlorvinphos is used to control lepidopterous and dipterous larvae in fruit and lepidopterous larvae in cotton, maize, rice, tobacco and vegetables. It is also used against nuisance flies in animal houses, animal ectoparasites and stored product pests.
Hazard
Cholinesterase inhibitor. Questionable carcinogen.
Carcinogenicity
When rats were given diets with 0, 4250, or 8500 ppm tetrachlorvinphos for 80 weeks, both males and females had a high incidence of thyroid C-cell hyperplasia, and females had increased incidences of adrenal cortical adenomas and thyroid C-cell adenomas .
Environmental Fate
Tetrachlorvinphos is nonpersistent in the environment. The primary route of dissipation is through biotic degradation. Based on its use pattern, risks of contamination of groundwater or surface water by tetrachlorvinphos are minimal.
Metabolic pathway
The chemical structure of tetrachlorvinphos is very close to that of chlorfenvinphos and the routes of metabolic breakdown have been shown to be very similar. Technical tetrachlorvinphos is usually >95% Z-isomer, unlike chlorfenvinphos which is an E/Z mixture. As with chlorfenvinphos, the major routes of detoxification are by dealkylation and hydrolysis to yield desmethyltetrachlorvinphos and 2,2’,4’,5’- tetrachloroacetophenone plus dimethyl phosphate, respectively. Further metabolism of the chloroacetophenone moiety then leads, via reduction or hydrolysis and glutathione-dependent displacement of the side chain chlorine substituent, to the formation of 1-(2,4,5-trichlophenyl) ethane-l,Z-diol and 1-(2,4,5-trichlorophenyl)ethan-l-owl hich are conjugated with glucose or glucuronic acid to afford the ultimate metabolites. Oxidation of the β carbon atom to give 2,4,5-trichloromandelic acid followed by decarboxylation leads to the formation of 2,4,5-trichlorobenzoic acid which is conjugated with glycine in some mammals as the final metabolite. The metabolic routes were summarised by Beynon et al. (1973).
