Abstract: In order to comprehend the condition of heavy metal pollution of shellfish in haikou bay. we have detected the heavy mental content of Crassostrea rivularis and Meretrix meretrix. In the body of Crassostrea rivularis,Zn,Cu,Cd,Pb,Cr,heavy metal content is respectively: 101. 750,161. 751,0. 686,1. 200,2. 993 mg·kg-1.In the body of Meretrix meretrix,Zn,Cu,Cd,Pb,Cr,heavy metal content is respectively: 14. 060,1. 155,0. 071,0. 150,0. 225 mg·kg-1. In addition,the content of Zn,Cu,Cd,Pb,Cr in Meretrix meretrix from low to high is foot,Mantle and adductor muscle,viscera respectively. The results show that shellfish samples of heavy metal pollution index is small,the environmental quality is good. Furthermore,selective consumption of shellfish tissues and organs will greatly reduce the health risks.
