The article presents a study on the effects of organophosphorus, carbamate, pyrethroid and organochlorine pesticides and a heavy metal on survival and cholinesterase activity of chironomus riparius meigen. Organophosphorus and carbamate compounds are very widely used insecticides. They are toxic because they inhibit acetylcholinesterase (AChE), the enzyme that is responsible for hydrolyzing and so deactivating acetylcholine in the nervous system. AChE inhibiting pesticides can contaminate surface waters through unintentional drift of aerial spraying for agricultural use, through watershed drainage or accidental spillage, and even through intentional application.
