摘要
运用土壤风险控制值推荐模型,针对四川省建设用地中的居住用地和公园绿地的土壤污染风险筛选值进行了分析研究。结果表明:居住用地的苯、甲苯、乙苯、氯苯、苯并[a]蒽和苯并[a]芘6种有机污染物的土壤筛选值分别为0.17 mg/kg、955.63 mg/kg、0.71 mg/kg、23.62 mg/kg、2.57 mg/kg和0.32 mg/kg;公园绿地的筛选值则为0.36 mg/kg、2135.54 mg/kg、1.13 mg/kg、24.49 mg/kg、8.97 mg/kg和0.88 mg/kg,公园绿地6种有机污染物的土壤筛选值均高于居住用地的筛选值。与建设用地土壤污染风险管控标准相比较,居住用地的土壤筛选值均小于建设用地标准,而公园绿地土壤筛选值不同的污染物,比较结果也有所差异,反映出暴露途径对于土壤筛选值的结果有较大的影响。
The recommended model of soil risk control values was used to analyze the soil risk screening values of residential land and park land in Sichuan province.Following results were obtained:the soil risk screening values of benzene,toluene,ethylbenzene,chlorobenzene,benzo[a]anthracene and benzo[a]pyrene in residential land were 0.17mg/kg,955.63 mg/kg,0.71 mg/kg,23.62 mg/kg,2.57 mg/kg and 0.32 mg/kg,respectively.The soil risk screening values of park land were 0.36 mg/kg,2135.54 mg/kg,1.13 mg/kg,24.49 mg/kg,8.97 mg/kg and 0.88 mg/kg,respectively.The soil risk screening values of six organic pollutants in park land were higher than those in residential land.Compared with the risk control standard for soil contamination of construction land,the soil screening values of residential land are less than that of construction land,while the soil screening values of park land are also different with different pollutants,which reflects that the exposure path has a great influence on the results of soil screening values.
