DIAZINON AND PORPHYRIA CUTANEA TARDA
Medical Journal of Australia, 1979Cutaneous 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, 1971A 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, 2020With 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, 1993Diazinon 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
1969The 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

Degradation of diazinon in soil
Journal of the Science of Food and Agriculture, 1968AbstractThe 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‐

An Estimation of Diazinon in Omental Tissue
Journal of Analytical Toxicology, 1987A 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

Reviews of environmental contamination and toxicology, 2000
Diazinon use has significantly increased since its introduction more than four decades ago. Thus, today we are faced with environmental and health consequences that are largely inseparable from the insecticide's benefits. Fortunately, the research to date is of immeasurable value in making sound scientific and policy decisions regarding diazinon use ...
