城区不同区域土壤重金属含量与区域分布状况研究

摘要

随着工业化与城市化进程的逐步深入,化工以及交通等重金属污染产业的发展,某市的土壤重金属含量在不断累积.并且由于其传播途径十分广泛,受污染的范围也在不断增加,严重影响到城市发展与人体健康.通过对某市不同行政区域土壤样本的采样分析,调查了某市各行政区的土壤重金属污染情况,并进一步探讨了重金属污染可能的成因.%with the gradual deepening of industrialization and urbanization,development of industries that are likely to produce heavy metals pollution such as chemical,transport industries etc. ,heavy metals have been increasingly accumulated in soil of given city. Due to their wide range of transmis-sion routes,heavy metals contaminated areas have also been expanded steadily,which may endanger both urban development and human health of the given city. This paper presents the findings of a sur-vey on status quos of soil heavy metals pollution in given city through sampling and lab analysis ,and further discusses the possible causes for this situation.
