TLDR
The effects of an accelerated UV-aging procedure on polystyrene microplastics, which are used in products such as skin cleaners and foams, are investigated and it is shown that aging led to significant surface oxidation and minor localized microcrack formation.About:

Sorption behavior and mechanism of hydrophilic organic chemicals to virgin and aged microplastics in freshwater and seawater.
TL;DR: The sorption kinetics and isotherms models indicated that the sorption capacity of aged microplastic is higher than that of pristine microplastics, and their physical interactions, including partitioning, electrostatic interactions, and intermolecular hydrogen bonding, were the dominant mechanism.

New Insights into the Aging Behavior of Microplastics Accelerated by Advanced Oxidation Processes
TL;DR: This study investigated the alteration properties of polystyrene and high-density polyethylene microplastics by heat-activated K2S2O8 and Fenton treatments to improve the understanding of their long-term natural aging in aquatic environments and indicated that the O/C ratio was an alternative parameter to the carbonyl index (CI) to quantitatively describe the surface alteration properties.

Toxicity of Microplastics and Nanoplastics in Mammalian Systems
TL;DR: The prevailing data suggest that micro- and nanoplastic accumulation in mammalian and human tissues would likely have negative, yet unclear long-term consequences, and there is a need for cellular and systemic toxicity due to micro-and nanoplastics to be better illuminated, and the underlying mechanisms defined by further work.
Journal ArticleDOI
Effect of weathering on environmental behavior of microplastics: Properties, sorption and potential risks.
TL;DR: The review reveals the change in physicochemical properties of MPs and the release of additives and MP-derived intermediates during weathering processes and the interaction mechanisms of pristine and weathered MPs with pollutants are summarized.
Journal ArticleDOI
Adsorption behavior of organic pollutants and metals on micro/nanoplastics in the aquatic environment.
TL;DR: This review summarizes the effects of environmental factors on the properties and sorption behavior of microplastics, presents a further discussion on the fate ofmicroplastics adsorption on contaminants, and critically discusses the mechanism of sorption behaviors between micro/nanoplastics and normal contaminants.

Microplastics as contaminants in the marine environment: a review.
TL;DR: Ingestion of microplastics has been demonstrated in a range of marine organisms, a process which may facilitate the transfer of chemical additives or hydrophobic waterborne pollutants to biota.

Principles of QSAR models validation: internal and external
TL;DR: Evidence is presented that only models that have been validated externally, after their internal validation, can be considered reliable and applicable for both external prediction and regulatory purposes.

Plastic Resin Pellets as a Transport Medium for Toxic Chemicals in the Marine Environment

TL;DR: Field adsorption experiments using PP virgin pellets demonstrated significant and steady increase in PCBs and DDE concentrations throughout the six-day experiment, indicating that the source of PCBs, DDE, and nonylphenols is ambient seawater and that adsor adaptation to pellet surfaces is the mechanism of enrichment.
