Research advances in PAHs adsorption on soil-sediment interface

This paper summarized the harm, source, and distribution of PAHs in the environment, and introduced in stress the general action modes (including linear and nonlinear allocation models) of PAHs on soil-sediment interface and their applications. The main factors affecting the adsorption of hydrophobic PAHs pollutants were the structure and composition of the organic matters in soil and sediment, and the molecular characters of PAHs. Suggestions and expectations on further research in this field were put forward.
