Measurement of operator exposure to chlorpyrifos
Pest Management Science, 2013AbstractBACKGROUNDTo date, no research has been conducted to establish exposure levels for occupational pesticide operators under typical use scenarios in China. Through surrogate skin techniques (the whole‐body method), the authors monitored dermal and inhalation exposure of pesticide applicators in China. In addition, the exposure of pesticide mixers

A review of the reference dose for chlorpyrifos
Regulatory Toxicology and Pharmacology, 2006Chlorpyrifos is an inhibitor of cholinesterase (ChE) and inhibition of ChE is believed to be the most sensitive effect in all animal species evaluated and in humans from previous evaluations. Recent literature, in particular epidemiology studies reporting associations between chlorpyrifos levels and fetal birth weight decreases, suggest the need to ...

Chlorpyrifos: Pharmacokinetics in human volunteers
Toxicology and Applied Pharmacology, 1984The kinetics of chlorpyrifos, an organophosphorothioate insecticide, and its principal metabolite, 3,5,6-trichloro-2-pyridinol (3,5,6-TCP), were investigated in six healthy male volunteers given a single 0.5 mg/kg po and, 2 or more weeks later, a 0.5 or 5.0 mg/kg dermal dose of chlorpyrifos.

Environmental Fate of Chlorpyrifos
1993Chlorpyrifos is an organophosphorus compound that displays broad-spectrum insecticidal activity against a number of important arthropod pests. As a result, it is employed in a wide variety of agricultural and specialty pest control scenarios. Various formulations of chlorpyrifos have been developed to maximize stability and contact with pests and ...

Toxicologic evaluation of chlorpyrifos in cats
American Journal of Veterinary Research, 1988SUMMARY Twenty-four male domestic shorthair cats were used to evaluate the acute and chronic effects of a single, toxic but sublethal, orally administered dose of chlorpyrifos. A dosage of 10 mg/kg of body weight did not induce clinical signs of toxicosis, but a dosage of 40 mg/kg induced clinical signs of toxicosis, and 1 of 12 cats died. Chlorpyrifos

Chlorpyrifos degradation in turkish soil
Journal of Environmental Science and Health, Part B, 1999Degradation of chlorpyrifos was evaluated in laboratory studies. Surface (0-15 cm) and subsurface (40-60 cm) clay loam soils from a pesticide-untreated field were incubated in biometer flasks for 97 days at 25 degrees C. The treatment was 2 micrograms g-1 [2,6-pyridinyl-14C] chlorpyrifos, with 74 kBq radioactivity per 100 g soil flask.
