某石油化工园区土壤污染状况调查研究

Investigation and Evaluation on Soil Pollution in a Petrochemical Industrial Park

通过对某石油化工园区潜在风险区域26个土壤样品采集,调查研究了园区内土壤中重金属及无机物、挥发性有机物、半挥发性有机物等污染物的空间分布和污染情况。基于《土壤环境质量标准建设用地土壤污染风险管控标准(试行)》(GB36600-2018)中第二类用地筛选值标准,运用单因子指数法、内梅罗综合指数法对园区内土壤污染现状进行了评价。结果表明:该企业日常运行对园区内土壤状况尚未造成明显的污染,但部分区域挥发性有机物有检出,可能是由于大气污染沉降等对土壤造成了一定的影响。

By the collection 26 soil samples of potential risk areas in a petrochemical industrial park,the spatial distribution and pollution level of heavy metal、inorganic matter、volatile organic compounds and semi volatile organic compounds were studied.Base on the filter values of the second type of land in“Soil enviromental quality-Risk control standard for soil contamination of development land”(GB36600-2018),the soil was evaluated by the single factor index method and the Nemerow pollution index method.The results showed that:The daily operation of the enterprise has not caused obvious pollution to the soil condition in the park.However,volatile organic compounds were detected in some areas.It may be because air-pollution deposition has resulted ineffect on soil.
