山东省某产业园区土壤环境质量调查与现状评价

Evaluation and Characteristic Analysis of Heavy Metal Pollution in Soil of a Coking Plant in Shandong Province

为探究山东省某产业园区土壤环境质量现状,本文根据园区土壤环境质量监测数据,分析土壤中重金属以及挥发性、半挥发性有机污染物的含量,同时采用单因子指数法和综合污染指数法以及潜在生态风险评价指数法对土壤环境质量进行初步评价。结果表明,园区土壤状态呈酸性,土壤环境质量达到清洁水平,未受挥发性和半挥发性有机物污染。根据风险评价结果显示,2个基本农田监测点位和4个建设用地监测点位均未受重金属污染。镉(Cd)、汞(Hg)、砷(As)、铜(Cu)、铅(Pb)、铬(Cr)、锌(Zn)、镍(Ni)等8项重金属含量均低于《土壤环境质量农用地土壤污染风险管控标准(试行)》(GB15618-2018)和《土壤环境质量建设用地土壤污染风险管控标准(试行)》(GB36600-2018)中的标准限值。同时本研究结合园区实际情况对今后土壤环境治理工作提出合理的建议,为产业园区土壤环境污染的防控提供参考。

To explore the current situation of soil environmental quality in an industrial area,the content of heavy metals and organic pollutants were analyzed based on the monitoring data of soil environmental quality in the area.According to the relevant standards,the single-factor pollution index method,the Nemero comprehensive pollution index method and and the potential ecological risk index were used to evaluate the degree of soil pollution.The results showed that the soil condition of the area was acid,the soil environmental quality was up to the clean level,and it was not polluted by volatile organic compounds and semi volatile organic compounds.According to the results of risk assessment,two monitoring points of basic farmland and four monitoring points of construction land were not polluted by heavy metals.Eight kinds of heavy metals(Cd,Zn,Pb,Cu,As,Cr,Ni,Hg)were all lower than the standard limits in the standard for risk control of soil pollution on agricultural land of soil environmental quality(Trial)(GB15618-2018)and the standard for risk control of soil pollution on construction land of soil environmental quality(Trial)(GB36600-2018).Meanwhile,combined with the actual state of the area,some reasonable suggestions were put forward for the future soil environmental control work and some reference were provided for the prevention and control of the soil environmental pollution in this study.
