Acute and sublethal enzyme responses were assessed in the earthworm Aporrectodea caliginosa (Savigny) exposed to chlorpyrifos and diazinon in the laboratory, caliginosa , and field exposures. The aim of this work was to evaluate whether cholinesterase (ChE) activity has potential as a biomarker of organophosphate exposure in earthworms. No mortality or population changes were found at the recommended field application rates of the pesticides in the three experimental systems. Cholinesterase activity was severely inhibited in earthworms exposed to sublethal doses in laboratory tests. However, no effects of the pesticides on ChE were found in the mesocosm or natural worm populations. [ABSTRACT FROM AUTHOR] |
