摘要
以锦州市重污染企业、固体废物集中堆放场地和工业区周边区域内土壤为研究对象,共采集75份具有代表性的土壤样品,对其12项重金属、多环芳烃类和多氯联苯的含量进行分析,研究典型区域周围环境的土壤污染状况。采用Rapant et al.环境风险指数法的计算结果表明,表层土壤中重金属污染具有较大的环境风险,其中属于低环境风险级别的样品占近30%,中等环境风险级别的样品占近10%。由此,针对锦州市典型区域土壤的污染状况,提出相应的污染防治对策。
Soil in the surrounding area of heavy pollution enterprises,solid waste concentration sites and industrial areas in jinzhou city was studied.A total of 75 representative soil samples were collected.The contents of 12 heavy metals,polycyclic aromatic hydrocarbons and polychlorinated biphenyls were analyzed,and the soil pollution status of the surrounding environment was studied.According to the calculation results of environmental risk index method,the heavy metal pollution in the surface soil is of great environmental risk.Among them,samples of low environmental risk level accounted for nearly 30%,while samples of medium environmental risk level accounted for nearly 10%.Therefore,according to the pollution situation of soil in typical area of Jinzhou city,the corresponding countermeasures were put forward.
