摘要
为了探讨快速城市化和工业化城镇的企业及其产业类型对土壤重金属污染的影响,对东莞市大岭山镇的家具、电子、五金类企业周边土壤中Zn、Cu、Cr、Cd和Pb等重金属进行了调查分析,并与郊区菜地进行对比分析,结果发现:企业周边地区重金属污染显著高于菜地,污染严重,Cu、Cr和Cd受企业产业类型影响较为明显,而Zn和Pb不明显。
The concentration of Zn and Cu and Cr and Cd in soil near the enterprises of producing appliance and electrics in Dalingshan town in Dongguan are investigated and analyzed, which is compared with the vegetable field in outskirt. The results show that the heavy metal pollution in the soil near the enterprises is obviously higher than that of the vegetable field. There are distinctive impacts from Cu and Cr and Cd of the enterprises of producing appliance and electrics, however, the impacts from Zn and Pb is unobvious.
