摘要:
道路交通活动可导致道路两侧土壤重金属污染. 为了解川西北高原路侧土壤重金属污染状况,以四川省阿坝州红原县为例,研究不同车流量区域路侧重金属镉(Cd)、铜(Cu)、镍(Ni)、铅(Pb)、锌(Zn)的分布特征与规律,并采用单项污染指数法、尼梅罗综合污染指数法和潜在生态危害指数法评价公路交通导致的重金属污染情况. 结果表明:车流量增加对区域路侧土壤重金属含量产生了一定程度的影响,路侧土壤Cd和Zn含量均高于高寒草甸土壤的背景值含量,并随车流量增加呈上升趋势. 基于单项污染指数法的结果显示3种车流量等级区域路侧都受到Cd重度污染,部分区域受Ni、Pb、Zn轻度污染. 基于尼梅罗综合污染指数法的结果显示车流量大的区域路侧土壤存在重金属中度污染,车流量中等和车流量低的区域路侧土壤存在重金属轻度污染. 总体上,由于本地区道路建设和使用年限相对较短,与其他重金属污染严重的城市或地区比较,路侧重金属染污生态风险中等,但部分重金属元属(如Cd和Zn)的生态风险较大,随着道路使用年限的增加势必对当地生态平衡产生影响,需引起重视.

Abstract:
Traffic activities in roadways are the major source of heavy metal contamination on the northwestern Sichuan Plateau, China. To characterize the spatial pattern of heavy metal distribution, we collected soil samples and measured the concentrations of five heavy metals (Cd, Cu, Ni, Pb, and Zn) from nine sites in Hongyuan County, Sichuan Province, including three transects that reflected typical gradients of traffic density. Each transect consisted of three levels of traffic density sites. We calculated single pollution index, Nemerow multi-factor index, and potential ecological risk index, to assess the ecological risk of the heavy metal contamination. Results showed that the soils were contaminated by Cd and Zn, with higher concentrations than that of the natural soil background values in all sampling sites. Moreover, Cd and Zn concentrations increased with increasing traffic density, suggesting that traffic activities were potentially responsible for the metal contaminations. The single pollution index indicated that the study sites were heavily contaminated by Cd and slightly polluted by Ni, Pb, and Zn, and the Nemerow multi-factor and potential ecological risk indexes indicated moderate potential ecological risks at the study sites. Specifically, the sites with high traffic density were moderately contaminated and the sites with low traffic density were mildly contaminated. In general, Cd and Zn were highly accumulated in soils of the study region; therefore focus should be on the high ecological hazard associated with soil heavy metal contamination, even in undeveloped regions.
