胶州湾沉积物对海洋生物重金属富集的影响分析

本文对胶州湾沉积物和海洋生物重金属含量进行了统计分析。首先用地球化学法对海洋生物重金属富集特征进行了分析,然后用Spearman’s相关系数法分析了沉积物重金属含量和海洋生物重金属含量的相关性。分析结果表明鱼类对重金属的富集能力最差,而贝类和藻类较强;沉积物重金属均能促进或抑制海洋生物对重金属的富集,而对贝类的抑制作用最强。此结果可以为海洋生物的选择性养殖和种植提供依据。

An analysis of impact of sediments on heavy metal enrichment in halobios of the Jiaozhou Bay

This paper has analyzed the heavy metal content in halobios and sediments of the Jiaozhou Bay.The authors first used geochemical method to analyze the enrichment characteristics of heavy metals of halobios,and then adopted the Spearman’s correlation coefficient analysis method to analyze the relationship between the heavy metals in halobios and sediments.The analytical results show that fish has low ability in enriching heavy metals,whereas shellfish and algae have strong ability in this aspect.The heavy metals in sediments can also stimulate or prohibit the absorption of other heavy metals by halobios and have especially strongest inhibition function on shellfish.The results obtained by the authors can provide a basis for selective breeding and planting of halobios.
