摘要：
Microplastics as emerging pollutant are widely present in marine and coastal environments. Microplastics have a large specific surface area and strong hydrophobicity, and thus they can easily adsorb organic pollutants in the water environment. Due to their size close to the fee-ding diameter of aquatic organisms, they are easy to be ingested by organisms and enriched along the food webs, which has attracted worldwide attention in recent years. The current articles on microplastics have done a thorough investigation on the distribution and quantity of microplastics in the environment, and a lot of research has been conducted on the adsorption principles and kinetics of microplastics and typical pollutants. However, the sampling met-hods for the investigation of microplastics in the environment are not uniform, and the models for analyzing migration and biological effects of microplastics are simple and weakly adaptable. In addition, the research on the compound environmental effects caused by the interaction of microplastics and environmental pollutants is insufficient, and the integrity of the environmental behavior and biological effects of microplastics are easily ignored. In this paper, the distribution and abundance of microplastics in the environment and the adsorption of organic pollutants in the environment by microplastics are introduced; and then the presence of microplastics on persistent organic pollutants in the water environment of distribution and bioavailability are analyzed; the types and properties of microplastics, the types of pollutants, environmental conditions and other factors on the environmental behavior of microplastics are also discussed; finally, the combined biological effects of microplastics and organic pollutants are discussed in combination with the characteristics of microplastics and organic pollutants, and the size of microplastics. There are many types of microplastics and they interact closely with pollutants in environmental media. Therefore, it is of great significance to discuss the environmental behavior of microplastics in combination with the interaction characteristics of microplastics with pollutants and environmental characteristics. © 2020, Materials Review Magazine.
