The research status of microplastics leaching solution is reviewed.The detection methods of mi-croplastic leaching solution are summarized,the main components of microplastic leaching solution are summarized,the basic composition is summarized,the role of additive leaching in water and their harm to water and aquatic life are summarized.It is proposed that we should strengthen the research on the leac-hing behavior of additives from aging MPs,explore the relationship between the release rate of additives and the aging degree of microplastics,and pay attention to the enrichment of microplastic leaching liquid components in organisms and the transmission rules between different nutritional levels in the food chain.It is proposed to strengthen the supervision of the treatment and treatment of plastic products,actively look for replaceable materials,and research and develop effective waste plastics and microplastics disposal technology.
