The Environmental Adsorption and Combined Toxic Effects of Microplastics and Chemical Pollutants.

Microplastics (MPs) are a kind of emerging pollutants, which have diversified sources, wide distribution, high abundance and great potential harm, and have been included in the key control list of emerging pollutants by Shanghai. MPs in water environment can adsorb heavy metals and organic pollutants, and the adsorption capacity is affected by MPs type, particle size, aging degree and environmental conditions. As a carrier, MPs can carry inorganic or organic pollutants into organisms, change the concentration and distribution of pollutants in organisms, and affect the toxic effects of pollutants. The type of combined action between MPs and chemical pollutants varies with the types of pollutants, and its specific mechanism remains to be further investigated. Therefore, this paper reviewed the latest development of domestic and foreign literatures, systematically summarized the sources and current status of MPs pollution in soil and freshwater environment in China, analyzed the adsorption behavior of MPs to chemical pollutants, the influencing factors of adsorption and the combined toxic effects of MPS on organisms, and prospected the future development direction of related researches.
