某棉机厂地块土壤中总石油烃的污染特征及风险评估

Pollution characteristics and risk assessment of total petroleum hydrocarbons in soil at a cotton machinery plant site

在某棉机厂地块内共布置了86个土壤采样孔,对0~6m土壤进行分层采样,共送检488个土壤样品,分析土壤中总石油烃(C10-C40)的污染浓度及分层变化。结果表明:该地块土壤中总石油烃(C10-C40)污染风险不可接受,需要开展土壤修复工作。

A total of 86 soil sampling points were arranged within a plot of a certain cotton mill.Soil samples were collected in layers from 0 to 6 meters depth,totaling 488 samples,to analyze the pollution concentration and stratified changes of total petroleum hydrocarbons(C10-C40)in the soil.The results indicate an unacceptable level of total petroleum hydrocarbon(C10-C40)pollution risk in the soil of this plot,necessitating soil remediation efforts.
