Biomonitoring of anticholinesterase pesticides in the soil: usefulness of soil Collembola

Biomed Environ Sci. 1995 Sep;8(3):232-9.

Abstract

The impact of Methyl parathion and Carbaryl was evaluated on an ecologically important soil Collembola, Cyphoderus sp. Enzyme characteristics demonstrate substrate optimum at 1 10(-2) mol/L temperature optimum at 30 degrees C with a pH requirement of 8.0. In vivo inhibition of whole body AChE reveals higher degree of inhibition by LD50 dose of Methyl parathion as compared to that of Carbaryl where maximum inhibition was noticed at the agricultural dose.
