- 摘要:
- 以盐淮高速公路沿线为研究区域,分析了路基边坡及附近土壤中Cr,Cu,Pb三种重金属的污染特征,并对污染现状进行了评价.结果表明,土壤中三种重金属含量在不同采样区均存在显著差异(P<0.05),填土来源和交通量是造成各采样区土壤重金属含量差异的主要原因;在一定区域内,土壤中各重金属元素的含量随着离路肩距离的增加总体上呈现先降后升的趋势;在所有采样区土壤中,三种重金属含量高低排序为Cr>Cu>Pb,三元素之间具有显著的相关关系(P<0.01);对重金属污染现状潜在生态风险的评价表明,研究区域的生态风险程度为轻微级.
- Abstract:
- Through the characteristics analysis of the heavy metals (Cr, Cu, Pb) in the soils of Yanhuai expressway embankment slope, the heavy metal pollution was evaluated. The results showed that the contents of three heavy metals in soils of different sampling areas were significantly different (P<0.05).The source of filled soil and traffic were the main causes responsible for the difference of soil heavy metal contents in sampling areas. The heavy metal contents in soils appeared the trend in general that firstly declined and then rised with increase of the distance from expressway shoulder at some certain areas. The overall contents of three heavy metals from all sampling areas were ranked from high to low as Cr>Cu>Pb. The correlation among three elements was significant (P<0.01). The potential ecological risk assessment of heavy metal pollution showed that the ecological risk degree was slight under the current situation.
