武汉市东西湖农场表层土壤中多环芳烃的含量分布特征

Characteristics of Distribution and Concentration of PAHs in the Soil from Dongxihu Farm in Wuhan City

对武汉市东西湖农场土壤中多环芳烃的含量调查表明,除紧靠马路边、居民区的土壤中多环芳烃的浓度高于荷兰制定的土壤修复标准之外,其余地方均在此标准值之内,其中主要是高环多环芳烃含量超标严重。证明了汽车尾气所排放的多环芳烃要高于居民日常生活的排放量。多环芳烃在水平方向上的迁移存在色谱效应。

The investigation of Polycyclic Aromatic Hydrocarbons （PAHs） in soil from Dongxihu farm in Wuhan city concentrations of PAHs in the soils are less than that of the Holland standards for PAHs except that by the road and PAHs which concentrations are beyond Holland standards for PAHs in soils are high rings of PAHs. The concentration vehicle emission was more than that of habitations. There was a chromatographic effects in the horizontal migration of indicates that the residential areas. of PAHs from the the PAHs.
