Characterization and sensitivity to pollutants of cholinesterases in the Antarctic scallop Adamussium colbecki
Antarctica is affected by man-made contamination and development of sensitive ecotoxicological tools for impact assessment is a priority task. The aims of the present study were to characterize cholinesterase (ChE) activities in an Antarctic key species, the scallop Adamussium colbecki, and to inves...

Antarctica is affected by man-made contamination and development of sensitive ecotoxicological tools for impact assessment is a priority task.
