| 摘 要： | 根据大庆市城市功能区划,以表层土壤为研究对象,通过308个样品的采集、测定、分析,采用Hakanson潜在生态风险危害指数法评价土壤重金属元素的潜在生态危害程度,结果表明,表层土壤重金属污染程度较低,潜在生态危害风险较小,汞(Hg)和镉(Cd)是主要的潜在生态危害元素.汞的生态危害风险相对较大,有11.9%的样品处于较...

| Abstract: | Based on urban function zone divisions,308 surface samples were collected from the urban soils of Daqing City,Heilongjiang Province,China,and determined in laboratory.The potential ecological hazard of heavy metals in the surface soils were assessed by using Hakanson's potential risk index.The results show that the degrees of heavy metals pollution were lower in the surface soils of the study area,with lower potential ecological risk.As for the main hazard elements,Hg has higher ecological risk,of which 11.... |
