摘要
大连港及其附近海域底质表层样品铅含量分析表明,底质中铅含量较高,污染严重。北部重污染区,主要由于人类活动和表层沉积物颗粒较细所致;南部重污染区,主要由于周边地质条件和表层沉积物成因类型所决定。
The lead concentration of surface sediment samples collected from the Dalian Bay and the adjacent sea area have been examined.It is found Pb concentration is quite high and thus the surface sediment of the area has been heavily polluted.The pollution comes from two sources.In the northern part of the area it is basically caused by economic activities and fine sediments,while in the southern part it is mainly due to the peripheral geological structure and surface sediment's origins.
