Intoxication with carbamate insecticides and toxicological risk to animals

Metodi Petrichev

Abstract: Carbamate biocidal compounds (carbamic acid derivatives – aryl and alkyl esters) were discovered
in the early 1950s. Shortly afterwards, along with organophosphorus insecticides (ORPs), they began
to be widely used in the form of carbamate insecticides (CIs) with contact and gastric action, less often
systemic. They have a similar mechanism of toxic action to ORPs. A little later, esters of thiocarbamic
acid (thiocarbamates), which are mainly herbicides, were synthesized to the carbamine derivatives.
Dithiocarbamates, which are mainly fungicides, were then synthesized (Melnikov, 1987). Carbamate
insecticides are esters of methylcarbamic acid. Aryl esters of N-methylcarbamic acid have the strongest
insecticidal action.
