| 摘 要： | 研究了沈阳市城市土壤Pb的含量及其化学形态分布,结果表明:沈阳市土壤全Pb平均含量为106.41 mg/kg,变幅为5.65~279.81 mg/kg,各个土地利用类型Pb含量都超过了沈阳市土壤背景值,土壤Pb污染严重。土壤Pb各形态比例为残渣态>有机结合态>铁锰氧化物结合态>碳酸盐结合态>可交换态。各土地利用类型Pb的活性不大。

| Abstract: | The concentration and chemical speciation of Pb in Shenyang urban soils were studied.The results indicated that the mean Pb concentration in urban soils were 106.41mg/kg,ranging from 5.65 to 279.81mg/kg,the concentration of every land use type was higher than the background value in Shenyang city,and urban soils were seriously polluted with Pb.The Pb was dominated by residual,and followed by the order of residual>organic>Fe-Mn oxides>carbonate>exchangeable.The Pb activity of every land use type was not very high. |
