Acute Toxic Effects of Cadmium on Corophium acherusicum (Crustacean, Amphipod)
河蜾蠃蜚对镉的急性毒性响应(Acute Toxic Effects of Cadmium on Corophium acherusicum （Crustacean, Amphipod）)

Amphipod is developed as ideal test species for toxicity tests. It is necessary to develop indigenous test organisms for the quantitative assessment of pollutant toxic effects on aquatic organisms. Through cadmium spiked water-only toxicity test, the sensitivity of Corophium acherusicum exposed to cadmium was confirmed. Results showed that there were significantly positive correlations between the toxic effects of cadmium on Corophium acherusicum and the concentrations of cadmium, and the toxic intensity became higher as the exposure time increased. The 96h LC50 value of cadmium for Corophium acherusicum was 1.46mg·L-1, coinciding with the 96h LC50 of cadmium for various amphipods obtained from the literatures.
