摘要
传统塑料的使用带来了严重的全球塑料污染,生物可降解塑料因其在自然环境条件下较快降解近年来备受关注.然而,生物可降解塑料在环境中难以得到完全降解,可能释放出更多的微塑料,从而造成更为严重的微塑料污染.有机污染物会通过某些吸附机制被吸附到微塑料上,进一步在生物体内解吸,并随食物链转移,最终对人类健康造成威胁.本文详细归纳目前生物可降解微塑料(biodegradable microplastics,BMPs)与有机污染物相互作用的研究进展现状,并重点评述了BMPs的性质(种类、粒径、老化)和环境因素(pH、溶解有机物、离子强度、重金属离子共存)对BMPs对有机污染物的吸附行为及机理的影响.最后提出研究中存在的问题,并对未来的研究方向进行了展望,以期为相关研究提供参考.
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.
