“…They are bonded by chemicals that can be released into food, especially when heated, thus exposing human health to danger. Foams just like other types of microplastics can act as carriers of hydrophilic pollutants such as antibiotics (Zhou et al, 2017), and organophosphorus esters and phthalates due to their porosity (Zhang et al, 2018a).…”

Microplastics, which serve as sources and vector transport of organic contaminants in both terrestrial and marine environments, are emerging micropollutants of increasing concerns due to their potential harmful impacts on the environment, biota and human health. Microplastic particles have a higher affinity for hydrophobic organic contaminants due to their high surface area-to-volume ratio, particularly in aqueous conditions. However, recent findings have shown that the concentrations of organic contaminants adsorbed on microplastic surfaces, as well as their fate through vector distribution and ecological risks, are largely influenced by prevailing environmental factors and physicochemical properties in the aquatic environment. Therefore, this review article draws on scientific literature to discuss inherent polymers typically used in plastics and their affinity for different organic contaminants, as well as the compositions, environmental factors, and polymeric properties that influence their variability in sorption capacities. Some of the specific points discussed are (a) an appraisal of microplastic types, composition and their fate and vector transport in the environment; (b) a critical assessment of sorption mechanisms and major polymeric factors influencing organic contaminants-micro (nano) plastics (MNPs) interactions; (c) an evaluation of the sorption capacities of organic chemical contaminants to MNPs in terms of polymeric sorption characteristics including hydrophobicity, Van der Waals forces, π–π bond, electrostatic, and hydrogen bond interactions; and (d) an overview of the sorption mechanisms and dynamics behind microplastics-organic contaminants interactions using kinetic and isothermal models. Furthermore, insights into future areas of research gaps have been highlighted.

：Microplastics are ubiquitous in various environmental media on a global scale, and can adsorb co-existing pollutants, especially organic pollutants, thus changing the environmental behavior and toxicity of pollutants; they can also promote the migration of pollutants in different media through adsorption/desorption. Influencing factors and mechanisms of adsorption between microplastics and organic pollutants are necessary information for a comprehensive assessment of the environmental risks of microplastics and organic pollutants. Due to the complexity of composition, structure and surface characteristics of microplastics and the diversity of co-existing organic pollutants, the interaction between them is very complex. Based on a review of the relevant literatures in recent years, the authors systematically summarized the current status of occurrence and migration of microplastic in environmental media, the influencing factors of microplastic adsorption of organic pollutants and their interaction mechanisms, with a view to providing useful references for the in-depth understanding of the environmental behavior and ecological risks of microplastics.
