| 摘 要： | 利用地积累指数法和潜在生态风险指数法,对泉州市山美水库流域沉积物中重金属污染进行评价.结果表明,山美水库流域沉积物中主要重金属污染物是Cu,Pb,Zn,Cd;从总体的污染程度分析,重金属污染物的污染程度从大到小排列次序为Cd(偏中度污染),Pb(轻度污染),Zn(轻度污染),Cu(无污染);从重金属污染物生态风险程度分析,重金属污染物构成生态风险程度均属于轻度,从大到小的排列次序为Cd,Pb,Cu,Zn;山美水库流域沉积物中重金属污染程度总体上属于轻度污染,但是其桃溪下游、湖洋溪上游、水库入库口的重金属污染较为严重.

| Abstract: | Using the geoaccumulation index and the potential ecological risk index,the heavy metal pollution of Shanmei Reservoir of Quanzhou is evaluated.The results show that the main heavy metals are Cu,Pb,Zn and Cd in the sediments of Shanmei Reservoir Valley.According to the geoaccumulation index,the order of theheavy metals,arranged from highest to lowest pollution degree,is Cd(between slight and moderate degree),Pb(slight degree),Zn(slight degree),Cu(no pollution).The potential ecological risk to Shanmei Reserv... |
