Abstract:

Argopecten irradiams of Rizhao was cultivated in seawater with cadmium concentrations of 0.001, 0.0025, 0.005 and 0.01 mg/L and a control respectively, and the rule of accumulation and elimination of cadmium was studied. The experimental results showed that the cadmium accumulation in Argopecten irradiams increases with the increase of cadmium concentration in seawater and cultivation time. Furthermore, the cadmium accumulation in viscera is more serious than in muscle. After stopping the cultivation, the speed of cadmium elimination from the body has a positive relationship with the cadmium accumulation in the body. But after a certain time of metabolism, the cadmium remnant is still higher in the previous high accumulation body of scallops.

Key words: Argopecten irradiams, muscle, viscera, cadmium, accumulation, elimination
