In this research, the adsorption destructive process of chlorpyrifos (CP,O,O-Diethyl-O-3,5,6-trichloro-2-pyridinyl phosphorothioate) as a noticeable organophosphate pesticide using in agriculture on the nickel tungstate (NiWO4) nanoparticles catalyst was investigated and monitored via the 31P nuclear magnetic resonance (31PNMR). The effects of various experimental parameters such as catalyst do...

BACKGROUND The data presented here are a response to calls for more direct measurements of pesticide residues in foods consumed by children and provide an opportunity to compare direct measures of pesticide residues in foods representing actual consumption with those reported by the U.S. Department of Agriculture Pesticide Data Program. OBJECTIVE We measured pesticide residues in 24-hr duplic...

A crude cell extract from a mixed bacterial culture growing on parathion, an organophosphate insecticide, hydrolyzed parathion (21 C) at a rate of 416 nmol/min per mg of protein. This rate of enzymatic hydrolysis, when compared with chemical hydrolysis by 0.1 N sodium hydroxide at 40 C, was 2, 450 times faster. Eight of 12 commonly used organophosphate insecticides were enzymatically hydrolyzed...

BACKGROUND The organophosphate insecticide chlorpyrifos (CPF), widely used for agricultural purposes, has been linked to neurodevelopmental deficits. Possible motor effects at low to moderate levels of exposure have not been evaluated. METHODS Prenatal exposure to CPF was measured in umbilical cord blood in a sample of 263 inner-city minority children, who were followed prospectively. At appr...

Dal Lake a Sub-Himalyan urban Lake is one of the most beautiful lakes of India and second largest in Jammu & Kashmir. Intensive farming practiced in the surrounding area of Dal Lake and its floating gardens leads to an enhanced vulnerability of crops to pests and indiscriminate use of pesticides. Possible transfer of these hazardous molecules from vegetable fields to the aquatic environment of ...

In a 1989 study, the California Department of Food and Agriculture (CDFA) determined that organophosphate pesticides used in orchard dormant spraying were being deposited on non-target row crops grown at distances less than and greater than 0.4 km from the site of pesticide application. The residues found on non-targeted crops may have been the result of drift during pesticide application or tr...

Background and aims: Researches show that exposure to pesticides is occupationally common in agricultural task. Organophosphate (OP) compounds are diverse classes of pesticides with the most well known applications as insecticides and, to a lesser extent, as herbicides in agriculture. Organophosphate poisoning (OPP) is a major problem worldwide, especially in developing countries, with millions...
