Two organophosphorus pesticides: methyl parathion and dicapthon
Acta Crystallographica Section C Structural Chemistry, 2014Structural studies performed in this laboratory of organophosphorus pesticides continue with these related compounds. The –NO2groups of methyl parathion (systematic name: dimethyl 4-nitrophenyl phosphorothioate, C8H10NO5PS) and dicapthon (systematic name: 2-chloro-4-nitrophenyl dimethyl phosphorothioate, C8H9ClNO5PS) make dihedral angles of 10.67 (8 ...

Methyl Parathion: A Review of Health Effects
Journal of Toxicology and Environmental Health, Part B, 2003Methyl parathion is an organophosphorus (OP) insecticide with insecticidal properties derived from acetylcholinesterase (AChE) inhibition; this same property is also the root of its toxicity in humans. Poisoning with methyl parathion leads to cholinergic overstimulation with signs of toxicity including sweating, dizziness, vomiting, diarrhea ...

Amperometric Detection of Parathion and Methyl Parathion with a Microhole‐ITIES
Electroanalysis, 2011AbstractAn amperometric sensor featuring a microhole‐liquid/gel interface for the detection of both parathion and methyl parathion is developed on the basis of their different kinetics behavior when interacting with the enzyme organophosphorus hydrolase (OPH).

Biodegradation, 2012
In this study, the mph gene encoding methyl parathion hydrolase from Pseudomonas sp. WBC-3 was expressed in Yarrowia lipolytica and the expressed methyl parathion hydrolase was displayed on cell surface of Y. lipolytica. The activity of methyl parathion hydrolase displayed on the yeast cells of the transformant Z51 was 59.5 U mg⁻¹ of cell dry cells ...

Bulletin of Environmental Contamination and Toxicology, 1974
This study determined the toxicity of parathion and methyl parathion to organochlorine compound-resistant and -susceptible populations of mosquitofish (Gambusia affinis). Mosquitofish can tolerate about 40 times more methyl parathion than parathion.

Persistence of methyl parathion residues on sunflower seeds
Bulletin of Environmental Contamination and Toxicology, 1966Growers of minor crops, or crops that yield marginal profits, face a particular problem in their efforts to control insect pests. Potential insecticide usage is often not great enough to stimulate widespread interest in securing data necessary to obtain a label for its use on the crop. Sunflower is a crop that falls within this category.

Parathion and Methyl Parathion Resistance in Diamondback Moth (Lepidoptera: Plutellidae) Larvae
Journal of Economic Entomology, 1989Laboratory selection of a susceptible strain of diamondback moth, Plutella xylostella (L.), with methyl parathion resulted in >2,600-fold resistance to this insecticide and nearly 500-fold cross-resistance to parathion. Selection with parathion caused> 1,000- fold resistance to parathion and methyl parathion.

FATE OF METHYL PARATHION IN AQUATIC CHANNEL MICROCOSMS
Environmental Toxicology and Chemistry, 1983Abstract The fate of methyl parathion and the development of biological communities were examined as a function of inorganic nutrient enrichment, inorganic nutrients plus glycerol and presence of sediments in two eight-compartment, continuous-flow channel microcosms.

The hematological effects of methyl parathion in rats
Journal of Hazardous Materials, 2008The effects of methyl parathion (MP) at sublethal concentration on hematological constituent [red blood corpuscles (RBC), white blood corpuscles (WBC), mean cell volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), platelet (PLT) counts, hemoglobin (Hb) and hematocrite (HCT) levels] and serum damage marker ...
