Organophosphorus pesticide poisoning

The Netherlands Journal of Medicine, 2008
Self-poisoning with organophosphate pesticides is a major health problem world-wide. Through the inhibition of acetylcholinesterase, organophosphorus poisoning is characterised by the clinical picture of acute cholinergic crisis. Other manifestations are the intermediate neurotoxic syndrome and delayed polyneuropathy.In the Western world, the ...

Estrogenicity of Organophosphorus and Pyrethroid Pesticides

Journal of Toxicology and Environmental Health, Part A, 2002
Although organophosphorus and pyrethroid pesticides are considered environmental contaminants, their estrogenic potentials are still ubiquitous and unclear. The present study was undertaken to evaluate the estrogenic activities of nine pesticides (phoxim, malathion, monocrotophos, dimethoate, opunal, fenvalerate, cypermethrin, permethrin, and ...

Confirmation of Pesticide Residue Identity: Part IX Organophosphorus Pesticides

Environmental Letters, 1975
This paper describes a confirmation procedure for residue levels of dyfonate, dichlorofenthion and cyanox. After extraction and quantitation by flame photometric detector (FPD)-gas liquid chromatography (GLC), the organophosphorus pesticides are hydrolyzed in a 10% methanolic-potassium hydroxide solution.

Determination of organophosphorus pesticides in water

1969
Increasing use of organic chemicals for agricultural purposes has caused great concern in recent years. Rachel Carson (1962) was one of the first to focus public attention on the possible hazards connected with pesticide use. Because of this concern, much work (Dugan et al.

Cyanobacterial Degradation of Organophosphorus Pesticides

2020
Pesticides are chemicals which are widely used for the protection of crops from the attack of pathogens. Pesticides include fungicides, insecticides, herbicides, and bactericides. Among the different classes of pesticides used, organophosphorus class of pesticides is commonly used for agricultural applications.

Toxic Effects of Organophosphorus Pesticides

Journal of Natural Resources and Life Sciences Education, 2000
In agriculture, organophosphorus compounds have value as insecticides. These compounds will disrupt nerve impulses in insects by binding to the enzymes that break down choline‐based neurotransmitters. With no enzyme to break down the neurotransmitter, overstimulation of the muscle occurs. The muscle will fatigue quickly and paralysis, followed by death,
