Clinical Toxicology, 1981
Dichlorvos, 2,2-dichlorovinyl dimethyl phosphate, an organophosphate insecticide, is widely used for the control of agricultural, industrial, and domestic pests (Fig. 1) [1]. Dichlorvos is administered orally as an anthelmintic to swine, horses, cats, and dogs.

Kinetics and mechanism for degradation of dichlorvos by permanganate in drinking water treatment
Water Research, 2009 The degradation kinetics and mechanism of dichlorvos by permanganate during drinking water treatment were investigated. The reaction of dichlorvos with permanganate was of second-order overall with negligible pH dependence and an activation energy of 29 ...

Clinical Pharmacology of Dichlorvos
Acta Pharmacologica et Toxicologica, 1981Abstract Polyvinyl resin formulation pellets (V‐3 and V‐12) containing dichlorvos were administered to male volunteers in single doses up to 32 mg/kg and repeated doses up to 16 mg/kg/day for up to three weeks. The cholinesterase activity depressions following single doses were dose related.

Atmospheric Chemistry of Dichlorvos
The Journal of Physical Chemistry A, 2011Dichlorvos [2,2-dichlorovinyl dimethyl phosphate, (CH(3)O)(2)P(O)OCH═CCl(2)] is a relatively volatile in-use insecticide. Rate constants for its reaction with OH radicals have been measured over the temperature range 296-348 K and atmospheric pressure of air using a relative rate method.

Alkylating Properties of Dichlorvos (DDVP)
Acta Pharmacologica et Toxicologica, 1981Dichlorvos (DDVP) is a methylating agent. In DNA from mice given 1.9 ± 10‐6 mol/kg of DDVP, a degree of alkylation of guanine‐N‐7 amounting to 8 ± 10‐13 mol methyl per g DNA, was found. From this, a rate of clearence of 29 hr‐1 was estimated. This value is in reasonable agreement with the value (55 hr‐1), calculated from published data on the ...

An inhalational toxicity study with dichlorvos
Archiv f�r Toxikologie, 1972Dogs, cats and rabbits were continuously exposed for eight weeks to dichlorvos atmospheres generated from impregnated polyvinyl chloride strips. Concentrations of dichlorvos in air were produced in the range 0.05 to 0.3 μg/l. No effects were found on the general health, behaviour, plasma and erythrocyte cholinesterase activities and ...

The chemical and biochemical reactivity of dichlorvos
Archives of Toxicology, 1978The chemical structure, reactivity and metabolic fate of the insecticide dichlorvos (2,2-dichlorovinyl dimethyl phosphate) are discussed in relation to the possible genotoxicity of this and other methyl phosphate triesters. Recent attempts to demonstrate the methylation of DNA following exposure of bacteria and animals to dichlorvos are reviewed.

Chemistry of Metrifonate and Dichlorvos
Acta Pharmacologica et Toxicologica, 1981Abstract This is a survey of the chemistry of metrifonate and dichlorvos, including methods of synthesizing hydroxy‐phosphonic acid esters and enolphosphates. The reactive centres of metrifonate and dichlorvos and some kinetic measurements are included. Reaction mechanisms and the insecticidal mode of action are discussed.

Metrifonate and Dichlorvos: Cytogenetic Investigations
Acta Pharmacologica et Toxicologica, 1981Abstract Contradictory results are found in the literature about the cytogenetical effects of dichlorvos and metrifonate in mammals whereas their chromosome breaking ability was demonstrated in plant and Drosophila cells. They were tested on both in vitro and in vivo cells for chromosome breakage.
