Concentration and movement of diazinon in air

Journal of Environmental Science and Health, Part B, 1982
Airborne concentrations of diazinon were measured in rooms for 21 days after crack and crevice application. Residue levels were largest in treated rooms (38 micrograms/m3) after application, followed by adjacent (1 microgram/m3) and upper and lower rooms (ca. 0.4 microgram/m3). Low levels of diazinon were detected in all rooms 21 days after application.

Fatal Diazinon Poisoning in Man

Journal of the Forensic Science Society, 1974
A case of fatal diazinon poisoning is reported and a gas chromatographic method for detection and determination of the poison in human tissues is described. Concentrations found in the stomach, small intestine, brain, liver, kidney and lung are given.

Health Effects of Diazinon on a Family

Journal of Toxicology: Clinical Toxicology, 2004
There is increasing evidence of permanent sequalae from acute organophosphate poisoning. We report on accidental diazinon overexposure with acute organophosphate poisoning through cutaneous absorption and inhalation followed by persistent neurological effects.

DIAZINON AND PORPHYRIA CUTANEA TARDA

Medical Journal of Australia, 1979
Cutaneous application of diazinon to rats over a period of 12 weeks gives rise to a condition biochemically indistinguishable from porphyria cutanea tarda. Faecal porphyrin levels are elevated with the appearance of isocoproporphyrin in the faeces. Oral administration of diazinon does not appear to cause any disturbance of porphyrin metabolism.

Development of a diazinon-degrading bacterium in paddy water after repeated applications of diazinon

Canadian Journal of Microbiology, 1971
A decline in the brown planthopper control effectivity of diazinon was noticed after its continuous application to rice paddies for [Formula: see text] years at the International Rice Research Institute. In a study undertaken to determine the factor involved in this decline, rapid inactivation of diazinon was recorded within 3 to 5 days of its ...

Diazinon for control of sheep scab

Veterinary Record, 2020
With reports of sheep scab mites ( Psoroptes ovis ) developing resistance to macrocyclic lactone (ML) injections,1 effective control through plunge dipping in 60 per cent diazinon is, therefore, essential in eradicating ML resistant mites. In terms of plunge dipping, three critical dip wash concentrations are recognised: n Initial (IC) – 400 mg/l for

Percutaneous absorption of diazinon in humans

Food and Chemical Toxicology, 1993
Diazinon is an organophosphorus insecticide which, through general use, comes into contact with human skin. To investigate its percutaneous absorption, human volunteers were exposed for 24 hr to 14C-labelled diazinon applied in acetone solution (2 micrograms/cm2) to the forearm or abdomen, or in lanolin wool grease (1.47 micrograms/cm2) to the abdomen.

Kinetics of hydrolysis of diazinon and diazoxon

1969
The widespread use of organic insecticides 1 in agricultural pest control has raised considerable concern over their potential contamination of water resources. More recently, however, direct analysis by gas-liquid chromatography indicates that most surface waters and some ground waters contain trace amounts of organic insecticides. Consequently, these

An Estimation of Diazinon in Omental Tissue

Journal of Analytical Toxicology, 1987
A fatality in which diazinon was the suspected toxic agent was investigated. Samples of omental tissue, blood, and liver tissue were examined by gas chromatography and thin layer chromatography. Diazinon was found in the omentum (at a level of 5.1 mg/kg) and blood (in a trace amount), but no diazinon was found in the liver tissue. Methods are given for

Degradation of diazinon in soil

Journal of the Science of Food and Agriculture, 1968
AbstractThe disappearance rate of diazinon in two different soils, at two levels of water content, with two different diazinon concentrations, and in steam‐treated and untreated soils has been studied. The rates of disappearance were measured by the slopes of the disappearance curves in a semi‐logarithmic coordinate system and by the corresponding half‐
