| 摘 要： | 多环芳烃是典型的疏水性有机物,在土壤中很难被生物降解和利用。多环芳烃的老化作用、非水相基质的形成都会降低多环芳烃的生物有效性。多环芳烃生物有效性同时受很多因素的影响,如土壤理化性质、多环芳烃与土壤接触时间、多环芳烃性质和环境因素等。对于评价土壤中多环芳烃生物有效性来说,目前有许多化学和生物的方法被广泛使用。

| Abstract: | Polycyclic aromatic hydrocarbons are typical of hydrophobic organic compounds,which are difficult to be biodegraded and utilized.Bioavailability of polycyclic aromatic hydrocarbons was reduced due to the ageing,the formation of non-aqueous-phase liquids.Soil physical,chemical properties,contacting time between polycyclic aromatic hydrocarbons and soil and some other environmental factors play important roles on bioavailability.The bioavailability can be evaluated with biological and chemical methods. |
