| 摘 要： | 对杭州城区34条河道45个点位河道底泥进行采样,分析了pH及汞、砷、铅、铬、镉、铜、锌、镍等重金属含量,并进行污染及潜在生态风险评价。结果表明,监测点位的底泥为中性偏碱性,重金属含量分布不均,且范围波动很大,部分河道底泥重金属中汞、铅、镉、铬、锌、镍等有不同程度的超标,少数河道镉、铬、锌污染严重;按《农用污泥中污染物控...

| Abstract: | River sediments were sampled from 45 points in 34 rivers in Hangzhou,which were analyzed for pH and contents of heavy metals including Hg,As,Pb,Cr,Cd,Cu,Zn and Ni.The assessment of pollution and potential ecological risk showed that the river sediments from the monitored points were neutral partial alkaline;the contents of heavy metals distributed uneven and varied very much;the heavy metals of Hg,Pb,Cd,Cr,Zn and Ni from a part of river sediments exceeded standard in differentdegrees and a few ones polluted... |
