Veterinary aspects of insecticides: Organophosphates

New Zealand Veterinary Journal, 1971
Abstract Extract Unlike the organochlorine insecticides, organophosphates have little potential for accumulating as residues in either animal or plant tissues because, in general, they are readily broken down to non-toxic products. The toxicity of organophosphates to vertebrates varies widely—some have acute oral toxicities of the order of 1 or 2 mg ...

Suicide and exposure to organophosphate insecticides: Cause or effect?

American Journal of Industrial Medicine, 2005
AbstractBackgroundSuicide using pesticides as agent is recognized as a major cause of pesticide poisoning.MethodsA literature review of mortality and morbidity studies related to suicide among pesticide‐exposed populations, and of human and animal studies of central nervous system toxicity related to organophosphate (OP) pesticides was performed ...

An organophosphate insecticide: Chlorpyrifos

2021
Organofosfatlı bir insektisit olan klorpirifos tarımsal alanlarda üretimi ve verimliliği arttırmada, evlerde ve çeşitli kapalı alanlarda haşere ve patojenlerin kontrolünde en fazla tercih edilen geniş spektrumlu bir böcek öldürücüdür. Elde edilebilmesinin kolaylığı ve ucuz olması nedeniyle kontrolsüzce ve sıkça kullanılabilen klorpirifos, toprak, hava,

Chromosome studies in workers producing organophosphate insecticides

Archives of Environmental Contamination and Toxicology, 1979
The chromatid-type and labile chromosome-type aberrations occurred frequently in the factory-employees control group, probably caused by airborne pollution. Workers producing TECB (1,2,4,5-tetrachlorobenzene) showed a cluster of chromosome aberrations. No appreciable increase was found in the lindane workers; chromatid-type aberrations were moderately ...

Combined Effects of Phenothiazine and Organophosphate Insecticides in Cattle

Journal of the American Veterinary Medical Association, 1973
SUMMARY Calves (6–8 months old) were given phenothiazine, either as a single dose or as continuous low-level doses, or both, in amounts recommended for control of internal parasites or of fly larvae that develop in cattle feces. The cattle were then treated initially with one of the following insecticides: malathion, coumaphos, trichlorfon, or ronnel ...

Methyl Parathion: an Organophosphate Insecticide Not Quite Forgotten

Reviews on Environmental Health, 2006
Methyl parathion (MP), a toxic organophosphate insecticide approved for outdoor use only, is classified by the World Health Organization (WHO) as a Category Ia (extremely toxic) and by the United States Environmental Protection Agency (U.S. EPA) as a Toxicity Category I (most toxic) insecticide. In several U.S. states in the late 1980s and early 1990s,

Mechanisms of organophosphate insecticide-induced airway hyperreactivity

American Journal of Physiology-Lung Cellular and Molecular Physiology, 2004
It has been suggested that pesticide exposure may be a contributing factor underlying the increased incidence of asthma in the United States and other industrialized nations. To test this hypothesis, airway hyperreactivity was measured in guinea pigs exposed to chlorpyrifos, a widely used organophosphate pesticide.

Characterization of a streptomycete growing on organophosphate and carbamate insecticides

Archives of Environmental Contamination and Toxicology, 1986
A streptomycete bacterium was isolated from a field soil sample previously treated with the insecticide isofenphos and found to be capable of growing on several commercial carbamate and organophosphate insecticides. These included carbofuran, cloethocarb, trimethacarb, isofenphos, fonofos, ethoprop, and phorate but not terbufos.

Enantioselective interaction with acetylcholinesterase of an organophosphate insecticide fenamiphos

Chirality, 2009
AbstractEnantioselectivity in the environmental behavior and ecotoxicity of chiral pesticide is widely observed. However, the investigation of the enantioselective mechanisms remains limited. In this study, we used fenamiphos (FAP), an organophosphorus insecticide, to study enantioselectivity in toxicity to arthropods and the inhibition potential ...

Evaluation of the genetic toxicity of the organophosphate insecticide chlorpyrifos

Mutation Research/Genetic Toxicology, 1995
The genetic toxicity of chlorpyrifos [O,O,-diethyl-O-(3,5,6-trichloro-2- pyridinyl)phosphorothioate, C.A.S. Number: 2921-88-2)], an organophosphate insecticide, was examined by employing several end points such as gene mutations in bacteria (Ames test) and mammalian cell cultures (CHO/HGPRT assay), cytogenetic abnormalities in mammalian cells both in ...
