Pharmacology of Pesticides- organochlorine insecticides mechanism of action ,Feb 20, 1996·Specific organochlorine insecticides \BChlorinated ethane derivatives\n \B\fs<10.000>DDT\b - (use currently restricted) first synthesized in 1874, but not used as an insecticide till 1939. Probably one of the most effective synthetic insecticides. Low acute toxicity to animals, but accumulates in fatty tissues and may contribute to chronic ...Apparent solubility of organochlorine insecticides in ...The apparent solubility in water of several organochlorine insecticides has been examined and found to vary, depending upon the rate of centrifugation of the samples prior to analysis. Samples centrifuged at rates calculated to produce equivalent particle diameters based on Stokes’ law of 0.01, 0.05 and 5.0 microns showed increases of the average concentration in solution for all compounds ...



Organochlorine Pesticide - an overview | ScienceDirect Topics

H. Karasali, N. Maragou, in Encyclopedia of Food and Health, 2016 Organochlorines. The organochlorine pesticides (OCPs) are insecticides and characterized by three types of compounds: DDT analogs (Figure 1), benzene hexachloride (BHC), and cyclodiene compounds.OCPs are persistent and toxic chemicals, belonging to the group of persistent organic pollutants (POPs).

Insecticides | CADDIS Volume 2 | US EPA

Feb 16, 2021·Insecticides may affect aquatic biota via several different modes of action, and in many cases mode of action will vary with the type of insecticide. For example, organophosphates and carbamates increase cholinesterase inhibition; pyrethroids disrupt the functioning of sodium channels in neuronal membranes.

Interaction of the organochlorine pesticide dieldrin with ...

Dieldrin is an organochlorine insecticide highly toxic for human beings. Although its exact mechanism of action is not well known, there is evidence that it acts at the cell membrane level. In fact, the lipophilicity of the pesticide as well as that of the phospholipid bilayer present in biological membranes makes the latter a most likely ...

Organochlorine (OC) pesticides pose a significant environmental risk to wildlife and humans and have been associated with Alzheimer’s disease (AD). This study aims to spectroscopically analyze brains from free-flying birds and link the results to OC exposure and consequent amyloid aggregation.

Organochlorine Insecticide - an overview | ScienceDirect ...

Organochlorine Insecticide. Organochlorine insecticides have varied targets and mechanisms of action within the central nervous system that affect the function of sodium and calcium channels and transporters as well as interfering with γ-aminobutyric acid (GABA) neurotransmission by blocking specific GABA receptors, contributing to their neurotoxic effects (Narahashi et al., 1995).

Toxicity of pesticides to aquatic microorganisms: A review ...

For example, organochlorine, organophosphate, and carbamate insecticides act primarily by disrupting nervous system function, while herbicides target mainly photosynthesis pathways (Table 1). The mechanism of pesticide action in microbial species may not be the same as for the target organisms.
