| 中文摘要: |
| 以天津市某化工企业搬迁遗留污染场地为例，采用VOCs快速检测法辅助现场钻孔取样，以初步判断土壤污染深度，同时将现场样品送实验室检测。试验表明，VOCs快速检测法与实验室检测法结果基本一致。将452个样品测定结果做比对，结果表明实验室检测数据VOCs加和值与快速检测法现场检测数据存在显著相关，R2为0.803 7。污染物主要集中于场地5 m~9 m的粉土层中。其中，13种VOCs检出，4种VOCs超过《场地土壤环境风险评价筛选值》（DB11/T 811—2011）商业用地筛选值。 |

| A rapid VOCs detection method was used in the contaminated site of a relocated chemical enterprise in Tianjin, assisted with on site drilling for sampling. The depth of contaminated soil was preliminarily estimated, meanwhile, the samples were sent to laboratory. Comparison results from 452 samples showed that the detection data from laboratory had good correlation with the data from on site rapid method, (R2=0.803 7). The pollutants were mainly concentrated in soil at 5 m~9 m below the ground, among which, 13 kinds of VOCs were detected and 4 kinds of VOCs exceeded the commercial land value of “Screening Levels for Soil Environmental Risk Assessment of Sites” (DB11/T 811—2011). |
