摘要
用原子吸收法测定了渤海湾柱样沉积物中重金属的含量 ,分析了各元素在各站位的分布特征 ,同时对各重金属元素和有机质做了相关分析并对该海域底质环境进行了评价 ,结果表明 :各重金属含量随深度的分布特征由于受沿岸不同污染源的污染影响 ,重金属污染物难以形成一定规律的分布状态 ,总体上呈波折型分布 ;且该海域底质环境质量总指数已达很强的生态危害 ,其中主要污染元素是 Hg。
This paper presents the contents of heavy metals that are determined by atomic absorption spectrum (AAS) in the sample of column from Bohai Bay and spatial distribution of heavy metal The assessment of heavy metal and organic compound is also discussed And the results of measurement indicate that the spatial distribution of heavy metal do not form a certain feature because of the different pollution sources from the coast And the results of evaluation indicate that the sediment quality is markedly polluted and Hg is the primary element of pollution, which is seriously harmful to ecology
