Abstract

Toxicological effects of pesticides on aquatic organisms are very important, especially when these animals are serving as functional foods with respect to human consumption. Dichlorvos, one of the extensively used insecticides was investigated in the present study for acute toxicity following static bioassay method and fingerling common carp (Cyprinus carpio) was selected as test specimen. The 96 hour LC50 value was found to be 21.11 ppm. Impact of test conditions (hardness of water) on LC50 value was evidenced in the present research, water hardness has resulted in decreased toxic potential of test substance, there by increased LC50 value.
