Soil pollution research has become one of the important directions of environmental science development, and heavy metals and polycyclic aromatic hydrocarbons, as important pollutants in soil environment, are of great significance to the ecological security of soil environment. In this paper, the behaviors of heavy metals and polycyclic aromatic hydrocarbons (PAHs) in soil environment were briefly reviewed, and the pathways of their generation, harm, migration and transformation were also discussed.
