对污染场地修复过程挥发性有机物（ VOCs）散逸及浓度分布进行了检测分析，通过光离子气体检测仪（ PID）现场快速监测与采样管采样气相色谱质谱分析技术相结合的方式，进行了修复过程中VOCs散逸浓度检测，同时利用吹扫捕集法＋色谱／质谱检测分析方法进行了 VOCs污染场地内土壤中浓度检测。研究了VOCs在挖掘扰动过程中的散逸行为，并对气体中的VOCs浓度平面分布进行分析。结果表明，污染土壤中典型VOCs的散逸率整体上较高，对于该污染场地土壤特质，污染土壤扰动过程中，1，2?二氯乙烷散逸程度最高，苯散逸程度最低。 VOCs浓度并不因距离增加而呈现明显负相关关系，污染物在扩散过程中会出现波峰波谷的现象。
The escape and concentration distribution of voilitile organic compounds ( VOCs ) in the remediation process of a contaminated site was investisated. The concentration measurement was carried out through the combintion of P ID rapid monitoring and gas chromatography mass spectrometry with sampling tube. At the same time, the VOC concentration in the soils was detected by purge & trap + chromatography/mass spectrometry method. The escape of VOCs in the remediation process of the contaminated sites and the horizontal distribution of VOCs in the air was simulated on the basis of two groups of data. The results show that the dissipation rate of typical VOCs in the contaminated soil was high. For this contaminated soil, the 1,2?dichloroethane was the highest while benzene was the lowest. The VOC escape rate concentration is not negatively related to the distance rigorously, showing wave crest and trough alternately.
