| 摘 要： | 研究了连云港市城市表层土壤中Pb的含量及其赋存形态，结果表明，土壤中Pb的平均质量比为99mg／kg，变幅为41．3～184．2mg／kg，地质累积指数的评价结果表明连云港城市袁层土壤中Pb污染比较严重；表层土壤Pb主要以残渣态和铁锰氧化物结合态存在，有机结合态和酸可提取态较少；土壤中Pb活性较大，对城市环境具有一定的潜在危害。

| Abstract: | The concentration and fractionation of Pb in the topsoil of Lianyungang City are studied in this paper. Results show that the average concentration of Pb is 99 mg/kg, ranging from 41.3 to 184.2 mg/kg. According to Muller's index, the topsoil is seriously contaminated by Pb. Concretely speaking, the Pb in the urban topsoil of Lianyungang mainly consists of residuals and Fe-Mn oxide fractions, plus a small amount of organic fraction and acid-extractable fraction. Owing to its high concentration, Pb in urban topsoil is of great threat to the urban environment. |
