摘　　要：采用网格法布点 ,并参照美国EPA的采样和分析方法 ,调查了某润滑油添加剂厂区地下水中TPH、VOC及SVOC的分布特征 ,以开展风险评价和采取补救措施。结果表明 ,该厂区地下水的有机污染是局部的和特征性的 ;DRO高于 30mg/l的区域约占厂区面积的 16 9% ,浮油区域约占厂区面积的 12 7% ,污染物主要来自各类储罐的泄漏和污水隔油池的渗漏 ;93 8%的目标VOC及 94 2 %的目标SVOC检出率不足 2 5 % ,检出浓度较高的目标VOC和SVOC分别是苯系物和苯酚类化合物 ,推测定性VOC或SVOC的估算浓度高于目标VOC或SVOC的浓度。The concentration distributions of TPH, VOC and SVOC in groundwater at a lubricant additives plant site were investigated for conducting a risk assessment and remediation research Locations of groundwater monitoring well were selected based on grid location arranged method, and sampling and analysis were performed according to EPA method The results indicated that the contamination of groundwater by organic compounds was limited and the contaminants were characteristic The area where DRO concentration was exceeded 30 mg/l accounts for 16 9% of the total site area The area where free products were detected in groundwater accounts for 12 7% of the total site area The better part of contaminants was found to come from the leakage of various kinds of storage tanks and oil water separators The detected frequency for 93 8% of target VOC and 94 2% of target SVOC were lower than 25% In target VOC and SVOC aromatics and phenolic compounds were found to be of higher concentration The estimated concentrations of tentatively identified VOC and SVOC were higher than the detected concentrations of target compounds
