Effects of Weathering on the Sorption Behavior and Toxicity of Polystyrene Microplastics in Multi-solute Systems

Organic Contaminants and Interactions with Micro- and Nano-Plastics in the Aqueous Environment: Review of Analytical Methods

“…The sorption affinity was increased with the increase of ionic strength. Study results suggest that particles exposed to weathering processes and the simultaneous presence of several organic trace compounds may affect the biological ecosystem in the natural environment [79]. This is in contrast to a study by Koelmans et al (2016) on microplastics and hydrophobic organic chemicals (HOCs).…”

“…The authors conclude that more HOCs accumulate in natural prey and, thus, the risks from microplastics are not increased [10]. Aged PS particles are shown to generally exhibit higher levels of oxygenated functionality with lower surface hydrophobicity than unaged particles, which also influences the sorption capacity [79]. Due to the UV aging of the particles, the surface becomes rougher.…”

“…These causes the plastic to break into smaller and smaller pieces and additives can be released. Induced aging of particles can be carried out for instance by Photo-Fenton oxidation, UV-irradiation, or microbial degradation [79,97].…”

Current Progress on Marine Microplastics Pollution Research: A Review on Pollution Occurrence, Detection, and Environmental Effects

“…Normally, the additives in plastics are relatively environmentally friendly, but it has to be noted that microplastics can absorb other more toxic pollutants in the environment [97,[135][136][137][138][139][140]. These chemicals can be desorbed at certain conditions, which may pose higher toxic risks to microalgae [141,142], which needs more investigation.…”

Enhanced sorption of the UV filter 4-methylbenzylidene camphor on aged PET microplastics from both experimental and theoretical perspectives

“…[18][19][20] 4-Methylbenzylidene camphor (4-MBC) is a commonly used organic UV lter added to plastic personal care products to reduce the harm of radiation to human skin. 21 Studies [22][23][24][25] also indicate that 4-MBC can be easily uptaken by microplastics because of its hydrophobicity, and microplastics thereby become a platform transporting this contaminant into aquatic environments. Several studies [26][27][28] have shown that 4-MBC can exert adverse effects on the reproduction and development of marine species at environmentally relevant concentrations.…”
