Biochemical indices were investigated for their potential use as variables of sublethal toxicity in Daphnia (cholinesterase) and Chironomus (cholinesterase and biotransformation enzymes). Parathion, dichlorvos, and aldicarb caused dose-related inhibition of cholinesterase (ChE) in 24-h bioassays with both species. Ratios of Daphnia and Chironomus ChE IC50 values to corresponding immotility EC50 values derived from the same experiment covered the range 0.26 to 1.2. Estimates of the ChE… CONTINUE READING
