| 摘 要： | 以2007年6月采集的石家庄城市近地表降尘为对象,采用Hakanson提出的潜在生态危害指数法对石家庄城市近地表降尘中重金属污染及潜在生态危害进行评价.结果表明,石家庄城市近地表降尘中重金属元素含量变化均较大,Zn、Cd、Cr、Ni、Cu、Pb等属于强变异元素,重金属元素在近地表降尘中积累已达到严重程度；各重金属元素中...

| Abstract: | The atmospheric dust gathered in June, 2007 near the ground of Shijiazhuang City was assessed for the ecological hazard of heavy metals with the potential ecological hazard index suggested by Hakanson. The results showed that the range of heavy metal content was large, Zn, Cd, Cr, Ni, Cu, Pb were strong variation elements. The heavy metal elements accumulated to serious proportions. Among the heavy metal elements, Cd was at a strong potential ecological hazard level and Hg was at a very strong potential ecological hazard level, the others were all at mild potential ecological hazard level. Considering synthetically the potential ecological hazard of heavy metals, the percentages of slight, moderate, high and strong ecological hazard were respectively 2.0% , 15.1% , 30.6% , 52.3%. Therefore, the overall performance showed the strong potential ecological hazard, and heavy metal pollution in the atmospheric dust near the ground of Shijiazhuang City was serious. |
