摘要： 研究测定了土壤中铜的含量和形态分布规律.结果表明锌生产区土壤中的Cu总量分别约是土壤对照值、辽宁省土壤背景值、全国土壤背景值的14倍、37倍、49倍;而铜生产区则分别约是221倍、575倍、748倍,铜生产区污染很严重.同时铜主要是以较稳定的残渣态铜为主,铜生产区达63.4%,锌生产区为38.5%.可溶态和可交换态铜的含量很低,不同生产区两种形态总和不超过1%;两个生产区的碳酸盐态和有机态两种形态之和分别为55.6%,33.7%.

Abstract: The copper content determined in soil and the morphological distribution of copper in the site area of a smeltery in Liaoning were studied. The results showed that in the Zn-smelting area the total Cu content in soil is 14, 37 and 49 times as high as the corresponding correlation value, provincial background value (of soil elements) and national background value, respectively; whereas in the Cu-smelting area the total Cu content in soil is 221, 575 and 748 times, respectively. So serious the Cu-pollution of soil is in the Cu-smelting area. It was found that Cu is mainly in residue form that is relatively stable, and its content is 63.4% and 38.5% in Cu-smelting and Zn-smelting areas, respectively. The copper content in soluble and exchangeable forms is few, and the total Cu content in such two forms is not over 1% in Cu/Zn-smelting areas. The Cu content in carbonate and organic forms is 55.6% and 33.7%, respectively, as found in Cu-smelting and Zn-smelting areas.
