摘要/Abstract

摘要： 测定了福建省6市、县耕地土壤中的Cu、Zn、Cd、Ni、Pb、Hg、As等7种重金属元素的全量和可浸提态含量,并对测定结果进行了数理统计.结果表明,福建省耕地土壤存在着不同程度的重金属污染,但依元素不同而不同,重金属可浸提态含量占全量的10.0%～52.2%,也依不同元素而不同.全省土壤中,Cu、Zn、Cd、Pb、Ni的可浸提态含量与全量之间的相关达极显著水平,Zn、Cd、Pb、As等4元素含量之间存在着显著正相关,而Ni则只与Zn元素有极显著正相关,Cu和Hg与其它重金属元素的相关则均不显著.

Abstract: The total and extractable contents of 7 heavy metals in cultivated soil in Fujian Province were determined. Statistical results indicated that the cultivated soil in Fujian Province was polluted by heavy metals, but different heavy metals caused different pollution levels. The extractable contents of heavy metals accounted for 10.0 to 52.2 % of total contents, varying with different heavy metals. There was a significantly positive correlation between total and extractable content of Cu, Zn, Cd, Pb, and Ni. Besides, Zn, Cd, Pb and As had a significantly positive correlation to each other, while only Zn had a significantly positive correlation to Ni, and Cu and Hg were not significantly correlated to any of other heavy metals.

Key words: Soil pollution, Heavy metal, Extractable form, Cultivated soil, soil organic carbon, immigration region, land use change, Karst area of China, total nitrogen.
