An example of a chronic effect caused by certain pesticides is a drop in which essential body enzyme?

Cholinesterase is an essential enzyme involved in the proper functioning of the nervous system by breaking down the neurotransmitter acetylcholine. Certain pesticides, particularly organophosphates and carbamates, work by inhibiting cholinesterase activity, leading to an accumulation of acetylcholine. This can result in prolonged nerve signal transmission and various neurological symptoms.

The chronic inhibition of cholinesterase caused by exposure to these pesticides can lead to long-term health issues, including neurotoxicity and impaired nervous system function. Monitoring cholinesterase levels is therefore an important indicator of exposure to specific pesticides and their potential chronic effects on human health. Understanding the implications of cholinesterase inhibition is crucial for pesticide applicators and those handling these substances to mitigate health risks effectively.
