Concentrations and distributions of cadmium, copper, and lead in soils from several industrialized urban areas of Beijing, China were investigated. The mean concentration of Cd in surface soils was not significantly greater than the regional background concentration, while those of Cu and Pb were significantly greater than regional background concentrations. All soil profiles exhibited a decreasing trend in concentrations of Cd, Cu, and Pb with depth. Concentrations of Cu and Pb were greatest at a depth of 0-80 cm, and exceeded the regional concentrations. Concentrations of Cd, Cu, and Pb at some industrial sites would necessitate active remedial actions.
对中国北京几个工业化城区土壤中镉、铜和铅的浓度及分布进行了调查。表层土壤中镉的平均浓度并不显著高于区域背景浓度，而铜和铅的平均浓度则显著高于区域背景浓度。所有土壤剖面中镉、铜和铅的浓度均随深度呈下降趋势。铜和铅的浓度在0至80厘米深度处最高，且超过了区域浓度。一些工业场地镉、铜和铅的浓度需要采取积极的修复措施。
