IMPACT OF ATRAZINE ON ORGANOPHOSPHATE INSECTICIDE TOXICITY

Environmental Toxicology and Chemistry, 2000
AbstractAcute toxicity of selected organophosphorus insecticides (OPs; chlorpyrifos, methyl parathion, diazinon, and malathion) was determined for individual OPs and binary combinations of the OPs with atrazine to larvae of the midge Chironomus tentans.

Parasuicide by self-injection of an organophosphate insecticide

Human & Experimental Toxicology, 2001
Parasuicide by ingestion of organophosphate (OP) insecticides is common in Sri Lanka, but the use of the parateral route to self administer the poison is extremely rare. We report a patient who deliberately injected herself intramuscularly with an OP compound with suicidal intent. The clinical manifestations of OP poisoning were unpredictable and posed

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 ...

Acute organophosphate insecticide poisoning

Clinical Intensive Care, 1995
Organophosphates are irreversible acetylcholinesterase inhibitors. Intoxication with these compounds is a global health concern. Acute manifestations include muscarinic, nicotinic and central nervous system signs and symptoms. Diagnosis requires a high clinical index of suspicion.

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 ...

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.
