摘要

在受原油泄漏严重影响的热带森林土壤深处，证明了低分子量和中等分子量碳氢化合物的垂直选择性迁移。在受污染地区的侧区和一条浅水河流的沉积物中观察到相同的水平迁移模式，该浅水河流接受了森林的污染径流。由于介质的色谱特性，这种差异迁移导致了与油气岩屑成分相似的残留污染物的形成。这部分原油对环境的污染远远超出了最初被原油污染的区域。

Selective migration of low and medium molecular weight hydrocarbons in petroleum-contaminated terrestrial environments

A vertical selective migration of low and medium molecular weight hydrocarbons is demonstrated in the depth of a tropical forest soil heavily impacted by a crude oil spill. An identical pattern of horizontal migration is observed in the lateral zone of the polluted area and in the sediments of a shallow river which received the contaminated water runoff of the forest. The differential migration, which is attributed to the chromatographic properties of the media, resulted in the formation of a residual contaminant similar in composition to a gas-oil cut. The environmental contamination by this fraction extended far beyond the area initially polluted by the crude oil.
