| 摘要: |
| 2003年9月采集广西近岸海域鱼类、甲壳类和软体类的19种底栖生物样品,测定底栖生物体内重金属Hg、Cu、As、Pb和Cd的含量,分析评价底栖生物受重金属污染的程度。结果表明,广西近岸海域底栖生物体中重金属含量是鱼类:Cu > Pb > As > Hg > Cd,甲壳类:Cu > Pb > As=Cd > Hg,软体类:Cu > Cd > As > Pb > Hg;不同生物对重金属的富集能力不同,同一种生物对不同重金属的富集能力不同,其大小顺序依次为,鱼类:Hg > Cu > Pb > As > Cd,甲壳类:Cu > Pb > Cd > Hg > As,软体类:Cu > Hg > Cd > Pb > As;广西近岸海域底栖生物均未受到重金属污染,但鱼类体内Hg、软体类体内Cu、Cd和Hg和甲壳类体内Cu、Pb、Cd和Hg的积累问题严重,软体类生物体内Cd超过人体消费标准值,甲壳类生物体内Cd和Pb含量等于或超过人体消费标准值;该海域底栖生物体内重金属含量变化不明显。 |

| Abstract: |
| There were 19 species of benthons to be gathered from Guangxi inshore in 2003.The heavy metal Contents were analyzed and assessed in Benthons.The average contents of different heavy metal are arranged from high to low, as follow.Fish:Cu > Pb > As > Hg > Cd;Crustacea:Cu > Pb > As=Cd > Hg;Mollusk:Cu > Cd > As > Pb > Hg.The concentration of heavy metal in benthons was analyzed.The concentration of different heavy metal is arranged from high to low, as follow.Fish:Hg > Cu > Pb > As > Cd;Crustacea:Cu > Pb > Cd > Hg > As;Mollusk:Cu > Hg > Cd > Pb > As.Benthons have not polluted by heavy metal in Guangxi inshore.The concentration of Hg in fish is potentially serious.The concentration of Cu、Cd and Hg in crustacea is potentially serious.The concentration of Cu、Pb、Cd and Hg in mollusk is potentially serious.The contents of Cd in mollusk is beyond the Standard indexes of seafood.The Contents of Cd and Pb in crustacea exceed or be equal to the standard indexes of seafood.It is not obvious that the heavy metal contents of benthons change in different year. |
