摘要
为了解胶州湾的重金属污染历史 ,在李村河口取了两个沉积物柱状样 ,并分层测定了Cu、Zn、Pb、Cd、As、Sb、Bi、Hg等重金属的含量 .结果表明 ,相对于沉积区背景值 ,重金属含量偏高 ,已造成轻度污染 .沉积物年代分析结果显示 ,自 2 0世纪 80年代中期以来 ,沉积物重金属含量逐渐增大 。
Heavy metal pollution in the sediments of Licun river estuary has been discussed with two cores collected from the estuary. Comparisons show that there is only a light contamination of heavy metals in the research area, but the trend of increase in heavy metal concentrations reveals that the pollution has been aggravating since the early 1980's. More attention should be paid to preventing further pollution. Furthermore, the sedimentary rate in the estuary area has been determined by the use of 210 Pb geochronometry. The history of industry development of Qingdao has also been studied according to the sedimentation rate measured.
