摘要
介绍了有机污染物在土壤—水体系中的分配理论。该理论认为有机污染物主要被土壤有机质以非吸附的方式所吸收，所以多种污染物被同时吸收时不存在竞争作用，而且吸收量受到土壤有机质和有机污染物分子极性的影响。有机污染物在土壤有机质—水体系中的分配系数，主要与其水溶性有关。
The advances of the study in the field of the behavior of organic pollutants in soil and water were introduced. The introduction is focused on the theory of partition uptake of nonionic organic compounds by soil organic matter and the partition coefficients between soil and water. The uptakes were significantly controlled by the polarities of soil organic matters and the organic pollutants. The capacity of partition uptake was associated with the composition of soil organic matters and the solubility of organic pollutants in water.
