辽宁某油品公司原厂址地块砷及石油烃污染土壤风险评估研究

Risk Assessment Study on Arsenic and Petroleum Hydrocarbon Contaminated Soil in the Original Site of an Oil Company in Liaoning

以辽宁省某污染地块为例,开展地块土壤污染状况初步、详细调查及风险评估工作。本工作参考《建设用地土壤污染状况调查技术导则》、《建设用地土壤污染风险管控和修复监测技术导则》及《建设用地土壤污染风险评估技术导则》开展。结果表明:在第一类用地情景下,地块土壤中砷及石油烃(C10-C40)危害商均超过可接受范围,采用克里金插值法计算地块土壤总污染方量约为20518.7 m^(3)。

Taking a polluted plot in Liaoning Province as an example,preliminary and detailed investigation and risk assessment of the soil pollution status of the plot were carried out.This work is carried out with reference to the“Technical Guidelines for the Investigation of Soil Pollution Status of Construction Land”,“Technical Guidelines for Soil Pollution Risk Control and Restoration Monitoring of Construction Land”and“Technical Guidelines for Soil Pollution Risk Assessment of Construction Land”.The results show that under the first type of land use scenario,the hazard quotient of arsenic and petroleum hydrocarbons(C10-C40)in the soil of the plot exceeds the acceptable range,and the total soil pollution square calculated by kriging interpolation method is about 20518.7 m^(3).
