TLDR
In this paper, a 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.Abstract:
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.read more
