水环境中生物可降解微塑料与有机污染物的相互作用研究进展

The use of traditional plastics has caused serious global plastic pollution. Biodegradable plastics have attracted much attention in recent years due to their rapid degradation under natural environment conditions. However, biodegradable plastics are difficult to be completely degraded in the environment, which may release more microplastics and cause more serious microplastic pollution. Organic pollutants can be adsorbed onto microplastics through certain adsorption mechanisms, further desorbed in organisms and transferred along the food chain, ultimately posing a threat to human health. The current status of the interaction between biodegradable microplastics and organic pollutants were introduced in this study, especially the effects of the properties of microplastics (species, particle size, aging) and environmental factors (pH, dissolved organics, ionic strength, and coexistence of heavy metal ions) on the adsorption behaviors and mechanisms of organic pollutants by BMPs were discussed. Finally, the remaining problems and further research trends were prospected, with a view to providing references to the relevant studies.
