| 摘 要： | 为了探明陕北地区石油开采对周围黄土的污染状况,分别采集了延安市宝塔区姚店镇上童沟油井、王庄油井、李渠镇刺崖沟油井附近的土壤,测定了土壤的可溶有机质和总烃含量,并用气相色谱-质谱联机法(GC-MS)分析了土壤中的正构烷烃的组成及分布特征.结果表明:所查地区可溶有机质含量较高,且不同采样点的含量相差很大,平均含量分布在3 561~46 725 mg/kg之间;总烃平均含量分布在2 097~13 488 mg/kg之间,其中上童沟油井周围土壤总烃污染最为严重,最高含量是当地土壤背景值的27倍.由调查地区正构烷烃的碳数分布显示,土壤中烃类污染物主要来源于成熟原油及其衍生物,部分地区烃类污染来源为原油和高等植物蜡的混合物.

| Abstract: | In order to investigate the loess soil contamination caused by petroleum exploitation in the north of Shaanxi province,three groups of soil samples around local oil wells at different sites were collected,and the extractable organic matter(EOM) and the total petroleum hydrocarbon(TPH) were measured.The characteristics of the composition and distribution of normal alkane(n-alkanes) in the soil samples were analyzed by GC-MS.The results show that EOM in the loess soil was quite high and these three groups of ... |
