摘　　要：本文以四川省某工业渣场为研究对象,依据场地的情况,确定了45个钻孔,按照10~20 cm分层为土壤取样,测定了土壤中钡(Ba)、砷(AS)、锰(Mn)等重金属元素及硫酸根离子、氯离子的含量及特征分布。分析结果表明调查场地土壤主要受污染因子为钡、氯离子和硫酸盐,其次为砷、锰。Taking an industrial slag field in Sichuan Province as its research goal, based on the situation of the site, 45 boreholes were determined, and the content and characteristic distribution of heavy metals such as barium (Ba), arsenic (As), manganese (Mn) and sulfate ions and chloride ions were determined according to the stratification of 10~20 cm. The results showed that the main contamination factors were barium, chloride ion and sulfate, followed by arsenic and manganese in soil of investigated site.
