Research Progress on Ecotoxicological Effects of Micro-Plastics Loaded Pollutants

The origin of microplastics and the effects of ecotoxicological effects of microplastics on organisms were summarized in this paper. Microplastics can directly affect the environment, such as being ingested directly by organisms. Because microplastics are small in size, they can be eaten by organisms by mistake, so they can inhibit the digestive system, respiratory system, immune system, reproductive system and genetic level of organisms. Microplastics will gradually release the chemicals added in the production process, these chemicals have toxic effect on the environment. When the environmental factors change, the additives contained in the microplastics components will be degraded and released, which will have toxic effect on the environment. Microplastics, as carriers, can carry pollutants, which together with microplastics can cause complex pollution to the environment. Because of the physical properties of microplastics, it is easy to load various pollutants on their surfaces. This will result in a deeper level of complex pollution to organisms and the environment. The ecotoxicological effects of microplastics loaded pollutants on the environment are more complicated, so we should pay more attention to the ecological toxicological effects of micro-plastics loaded pollutants.
