摘　　要：本文采取色谱指纹技术应用于地下水中烃类污染物的来源判识。通过色谱指纹峰对比值分析油库内浮油和地下水中烃类与油库外地下水中烃类污染物的组成来源。研究结果表明:油库内不同井位地下水样品的色谱指纹峰对比值位于一个较小范围,具有较好相似性。油库内浮油与库外浮油色谱指纹也具有较好的一致性,同时,油库内与库外地下水中烃类色谱指纹也具有较好的一致性与相似性,以上特征揭示出库内外浮油与地下水中烃类组成相似,可能具有同一个来源。In this paper,chromatographic fingerprint technology is used to identify the source of hydrocarbon pollutants in groundwater.Use chromatographic fingerprint peaks to analyze whether there are differences in the content and structure of the hydrocarbons in the floating oil and the groundwater in the inside and outside of the oil depot.The research results show that the fingerprint peak response the ratios of fingerprint peak pairs varies within a small range,which can well indicate the relationship of hydrocarbons in the groundwater between inside and outside of the oil depotand.The hydrocarbons composition is basically the same in the inside and outside of the oil depot.
