摘要: 通过分层采样的方法,对上海八大垃圾填埋场土壤的物理性质、营养状况及重金属的污染状况进行了测定分析。结果表明:各垃圾填埋场填埋年限越长垃圾粒径越小; 各垃圾填埋场均存在土壤紧实、通气性差的现象; 土壤偏碱性,但不存在盐害现象。填埋场垃圾层中有机质和全N含量高于覆土层,且高于我国养分标准的一般水平,但全P含量有所不同,除共和新村外,各垃圾填埋场中全P含量均较高。就重金属而言,各垃圾填埋场As、Cd和Zn的含量较高,其分别是土壤环境质量Ⅲ级标准的5.35~12.95倍、 1.75~8倍和2.76~4.79倍; 通过主成分分析表明,有3个因子可以解释其来源的92.08%。

Abstract: The soil physical properties, nutrient conditions and the pollution characteristics of heavy metal in the eight municipal rubbish landfill sites in Shanghai were determined by using a laid sampling method. The results showed that the longer the rubbish landfill were operated, the smaller the soil particle size was. And the compacted and poorly aerated soil was universal in all rubbish landfills. The soil was alkaline. However, the salt injuries did not existed. The contents of organic matter and the total nitrogen in the rubbish layer were higher than that of the covering layer and above the ordinary level of the Chinese nutrition classification standards for soils, however, the content of total phosphorus was different and high in all soils except for Gonghexincun landfill. As far as the heavy metal was concerned, the contents of As, Cd and Zn were 5.35-12.95 times, 1.75-8 times and 2.76-4.79 times of the class Ⅲ environmental quality standard for soils, respectively. Further more, the factor analysis was applied to study the sources of heavy metal, the results showed that three factors were identified and could explain 92.08% of the sources.
