  • An attempt was made to analyze the changes of heavy metals in the soft tissue and shells of Crassostrea rivularis under the stress of copper ion. The results showed that the changes of the contents of different heavy metals in C. rivularis varied within a certain range of copper ion concentration. In the control group and the two experimental groups, the contents of copper in the soft tissue of C. rivularis were 67.42, 255.50 and 299.83 mg·kg-1, respectively. The content of copper in the soft tissue of C. rivularis was significantly higher in the experimental groups than in the control group. With the increase of copper ion concentration in the water, the contents of zinc in the soft tissue of C. rivularis in the control and two experimental groups were 984.17, 1 075.00 and 1 120.83 mg·kg-1, respectively, while As and Pb contents showed a downward trend, and Cd content had no significant change. In addition, the contents of Cu and Zn were generally higher in the soft tissue than in the shells. With the increase of copper ion concentration from 0.10 mg·L-1 to 0.15 mg·L-1, the contents of copper in the shell center of C. rivularis were 10.25, 11.17 and 17.83 mg·kg-1, the contents of copper in the shell edge were 10.33, 12.83 and 19.75 mg·kg-1, respectively, and the contents of copper in both shell edge and central parts rose significantly. And the content of Cu was higher in the newly formed shell edge than in the other parts of the shell.
