The Experimental Research on the Migration Characteristics of Polychlorinated Biphenyls (PCBs) in Soil

Because polychlorinated biphenyls (PCBs) are persistent and lipophilic, which is widely present in the environment, people paid more attention to the soil as it's the main accumulation of PCBs. The soil column leaching experiments were performed to simulate dynamic process of PCBs with water infiltration in unsaturated zone. The behaviors of PCBs including adsorption, dispersion and migration under various water conservancy conditions and soil physical and chemical properties were discussed. Provide a theoretical basis for the next step of the management of PCBs.
