As demonstrated in vitro studies, polystyrene nanoplastics (PSNPs) are effectively internalized by various cells. All known mechanisms of PSNP internalization involve the initial step their interaction with cell membrane, highlighting importance understanding such interactions at molecular level. Here we consider effects PSNPs obtained from disposable food packaging on zwitterionic lipid membranes, used as a model system for protein-free membranes. We combined microscopic imaging and unbiased atomistic dynamics (MD) to investigate behavior surface inside membrane. Our results show that hydrated have high negative charge when dispersed an aqueous media. The penetration PS nanoparticles into bilayer requires removal water molecules nanoparticle-membrane interface, which is effective barrier entry its hydrophobic region. Overcoming this energy slightly inserting nanoparticle polar region membrane leads rapid center coating molecules. do not disaggregate after penetrating affects structure bilayer. In addition, our MD simulations small-molecule additives (e.g., unreacted monomers) present can be released membranes if they located close surface. outcomes study important passive uptake

Plastic materials are increasingly present in our lives. It is estimated that more than 360 million tonnes of plastics produced annually worldwide. Particularly, single-use represent an important segment plastic production. In this context, contamination, and consequently microplastic release, has become a growing concern for aquatic ecosystems. study, we investigated the effects exposure to polyethylene terephthalate (PET) microplastics (<32 μm) on Chironomus sancticaroli larvae. The larvae were exposed different concentrations PET particles (0 (control group), 500, 5,000 particles.kg −1 dry sediment) 10 days. Our results demonstrated C. displayed their digestive tracts, ingestion increased with increasing concentrations. tract can reduce energy obtained by feeding and, consequently, impair development. adult emergence rate significant decrease observed at highest concentration compared control group.

Acrylonitrile-butadiene-styrene (ABS) is a thermoplastic copolymer commonly used in the electronics, automotive, and construction industries. In aquatic environment, formation of microplastics from larger-sized plastic waste occurs naturally, induced by physical, chemical, biological processes that promote aging these particles. Here, we investigated interactions between freshwater amphipod Hyalella azteca ABS (10–20 μm) (pristine after accelerated aging) over 7 days exposure. At end exposure period, evaluated ability H. to fragment particles, as well changes its oxidative stress biomarkers (SOD, CAT, MDA, GST) result promoted significant fragmentation The ratio this biofragmentation was more pronounced pristine Despite absence mortality exposed organisms, alterations were observed. results demonstrate aged and, consequent susceptibility organisms effects microplastic
