分析了北部湾东北部388～389渔区和东南部490～512渔区24种主要经济鱼类体中Cu、Pb、Zn、Cd、Cr、Ni的含量,结果表明:重金属平均水平为490～512渔区大于389渔区。不同科鱼类间重金属含量以及重金属元素在鱼体各种组织、器官的含量分布存在差异。并采用全国海岸带污染综合调查有关海洋生物污染评价标准,对北部湾主要经济鱼类重金属污染程度进行了评价,北部湾经济鱼类基本未受重金属污染或污染程度较轻。
The contents of Cu, Pb, Zn, Cd, Cr and Ni in 24 major economic fish from fishing areas 388 ~ 389 northeast of Beibu Gulf and 490 ~ 512 fishing areas in southeastern China were analyzed. The results showed that the average level of heavy metals was 490 ~ 512 fishing areas more than 389 fishing areas. The contents of heavy metals and the contents of heavy metals in different tissues and organs of different species of fish differed. The pollution degree of major economic fish in the Beibu Gulf was assessed using the assessment standards for marine biofouling in the comprehensive survey of coastal pollution. The economic fishes in Beibu Gulf are basically not affected by heavy metals or lightly polluted.
