Research Progress on The Adsorption and Their Mechanisms of Polycyclic Aromatic Hydrocarbons in Soil by Microplastics

The physicochemical characteristics and refractory properties of microplastics can adsorb and enrich polycyclic aromatic hydrocarbons in the environment, and then release the adsorbed and accumulated pollutants into other organisms, which will cause harm to the soil ecosystem. In this paper, the effects of microplastics type, size, density, aging degree and soil environmental factors on the adsorption of polycyclic aromatic hydrocarbons by microplastics were reviewed. This paper will provide a theoretical basis for exploring and revealing the combined pollution of microplastics and polycyclic aromatic hydrocarbons in the soil environment.
