摘要/Abstract

摘要：

在任丘油田南部的一口典型开发井周围5个剖面中共采集15个土壤样品，索氏提取法提取有机物，采用气相色谱—质谱方法对美国环保署（EPA）优先控制的16种多环芳烃（PAHs）进行分析测定。结果显示:研究区内土壤受到严重污染;PAHs总含量随深度增加总体呈先递增后递减趋势，峰值出现在约20 cm深度处；萘、芴、蒽、菲等低环芳烃占有很大比例，萘的含量最高；PAHs含量随环数的增加有递减趋势，但在距油井较近的剖面中高环芳烃含量所占比例有所增加；低环芳烃主要分布在0~20 cm深度范围内，中高环芳烃主要分布在20~30 cm深度范围内。

Abstract:

This paper, based on 15 soil samples in 5 profiles around a typical development well in the southern Renqiu Oilfield, measures the polycyclic aromatic hydrocarbons (EPA’s controlled 16 PAHs as perference) via gas chromatographymass spectrometry detector (GC-MS), with the results indicate that the soils in nearby the well have been greatly contaminated. The total PAHs declines with depth, and with a peak at 20 cm in depth. The lowring PAHs such as Naphthalene, Fluorene, Anthracene and Phenanthrene and so on have a big proportion, of which the Naphthalene is the most. The PAHs decreases with rings, but the highring PAHs have an increasing proportion towards the well. The lowring PAHs are distributed chiefly at a depth of 0~20 cm and the middlehigh ones at 20~30 cm.
