Abstract: Used hydrostatic test, cadmium ions solution (0, 0.2, 0.5, 0.8, 1.1 mg/L) prepared with deionized water at a water temperature of (10 ± 2) ℃ was used for 48 h acute toxicity test to Urechis unicinctus. The results showed that the activity of amylase in the body cavity of Urechis unicinctus was simply negatively correlated with the concentration of Cd2+ in the living water body of Urechis unicinctus, and with the increasing concentration of Cd2+ in the exposed water, Urechis unicinctus showed varying degrees of stress change.

Key words: cadmium, Urechis unicinctus, acute toxicity, amylase, biological indicator
