摘    要:为了解海口湾贝类重金属的污染状况,对海口湾的牡蛎、文蛤体中重金属质量含量进行了测定。结果表明:海口湾牡蛎体中Zn,Cu,Cd,Pb,Cr重金属的质量含量分别为101.750,161.751,0.686,1.200,2.993mg·kg-1。文蛤体中Zn,Cu,Cd,Pb,Cr重金属的质量含量分别为14.060,1.155,0.071,0.145,0.225mg·kg-1。文蛤斧足、外套膜和闭壳肌、内脏团中Zn,Cu,Cd,Pb,Cr等5种重金属的质量含量均呈现由低到高的趋势。海口湾贝类样品重金属污染指数较小,环境质量优良;对贝类组织器官选择性食用将大大降低危害健康的风险。

关 键 词:重金属  贝类  风险评价  海口湾

Abstract:In order to comprehend the condition of heavy metal pollution of shellfish in haikou bay. we have de- tected 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.
Keywords:heavy metal  shellfish  risk assessment  haikou bay
