Determination of Dichlorvos in Pears by Surface-Enhanced Raman Scattering (SERS) with Catalysis by Platinum Coated Gold Nanoparticles

Analytical Letters, 2021
A surface-enhanced Raman scattering (SERS) sensor is reported for the determination of dichlorvos, an organophosphate pesticide (OP), in pears. Platinum coated gold nanoparticles (Au@PtNPs) were used as secondary catalysts to provide signal amplification.

Clinical Pharmacology of Dichlorvos

Acta Pharmacologica et Toxicologica, 1981
Abstract 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, 2011
Dichlorvos [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.

Carcinogenicity of Dichlorvos

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.
