| 摘 要： | 探讨广州城市及近郊的土壤重金属含量特征。47个代表性土壤点的结果表明，广州表土的Cu,Ni,Zn,Pb,Cr分别为10．3，23．1，112．8，58．3和42．0mg/kg。从土壤类型看，除Ni外，路边土壤重金属平均含量最高，农业土壤（果园、菜园、作物土壤）和公园土壤居中，林地土壤普遍最低。汽车尾气和农业化学物质的投入是广州土壤中Pb污染的重要来源。工业活动的影响也不可忽视。

| Abstract: | Heavy metal concentrations in urban and suburb soils of Guangzhou were studied in this paper. The results show that averages of total Cu, Ni, Zn, Pb, Cr concentrations in surface soils were 10.3, 23.1, 112.8, 58.3 and 42.0 mg/kg. It is found that road side soil has the maximum average concentrations of heavy metals except for Ni, followed by agricultural soil and urban park soil. The minimum ones were found in forest soil. Automobile tail gas and repeated applications of agrochemicals were the major sources of Pb pollution in the soils. The industrial activities were also an important impact that could not be neglected. |
