摘    要:对宁波市沿海主要滩涂贝类养殖环境中的有机物、硫化物、总磷(TOP)、总氮(TON)、重金属(Cd、Cr、Pb、Hg、Cu、As)等的污染情况进行了分析与评价.研究结果表明:宁波市滩涂贝类养殖环境尽管受到了一定的污染,但总体状况良好,基本符合滩涂贝类养殖的使用要求.除了枯水期三北滩涂中有机物的含量略微超标,丰水期Cu的含量超标现象较为严重外,其它化学物质的含量均低于评价标准.数据分析表明,沉积物中各化学物质的含量与底质类型之间有着密切的联系,除了作为营养因子的总磷和总氮外,其它化学要素的含量均随着沉积物粒度的减小而增大.此外,沉积物环境中许多化学物质之间也存在着一定的相关性.

关 键 词:滩涂沉积物  贝类养殖  化学物质

Abstract:The contents and distribution features of such chemical factors as organic matter,oil,sulfide,TOP,TON,Cd,Cr,Pb,Hg,Cu,As and PCBs in sediments were investigated in this paper.The results showed that the culture environment of interdial shellfish was well on the whole,and could meet the using requirement of marine functional zoning.Except the content of Cu exceeded the evaluation standard in high water period,the contents of all the other chemical factors were lower than the standard.The contents of chemical factors had close relation to the sedimentary patterns.Except for the nutritional factors(TOP,TON),the contents of other chemical factors increased with decreasing size of sediment in a general way.In addition,most chemical factors also had certain correlation with one another.
Keywords:interdial sediment  shellfish culture  chemical substance
