Abstract As an emerging pollutant in the life cycle of plastic products, micro/nanoplastics (M/NPs) are increasingly being released into natural environment. Substantial concerns have been raised regarding environmental and health impacts M/NPs. Although diverse M/NPs detected environment, most them display two similar features, i.e.,high surface area strong binding affinity, which enable extensive interactions between surrounding substances. This results formation coronas, including eco-coronas bio-coronas, on different media. In real exposure scenarios, corona is inevitable often displays variable complex structures. The coronas found to impact transportation, uptake, distribution, biotransformation toxicity particulates. Different from conventional toxins, packages rather than bare particles more dangerous. We, therefore, recommend seriously consideration role safety assessments. review summarizes recent progress eco–coronas bio-coronas M/NPs, further discusses analytical methods interpret structures, highlights provides future perspectives.

Nano/microplastic (NP/MP) pollution is a growing concern for the water environment. Wastewater treatment plants (WWTPs) are considered major recipients of MP before discharging into local waterbodies. MPs enter WWTPs mainly from synthetic fibers through washing activities and personal care products. To control prevent NP/MP pollution, it essential to have comprehensive understanding their characteristics, fragmentation mechanisms, effectiveness current processes used in removal. Therefore, objectives this study (i) understand detailed mapping WWTP, (ii) mechanisms NP, (iii) investigate removal efficiency by existing WWTP. This found that fiber dominant shape MP, polyethylene, polypropylene, polyethylene terephthalate, polystyrene polymer type wastewater samples. Crack propagation mechanical breakdown due shear forces induced facilities (e.g., pumping, mixing, bubbling) could be causes NP generation Conventional ineffective complete MPs. Although these capable removing ∼95% MPs, they tend accumulate sludge. Thus, significant number may still released environment on daily basis. suggested using DAF process primary unit can an effective strategy initial stage goes secondary tertiary stage.

The production and disposal of plastics have become significant concerns for the sustainability planet. During past 75 years, around 80% plastic waste has either ended up in landfills or been released into environment. Plastic debris environment breaks down smaller particles through fragmentation, weathering, other disintegration processes, generating microplastics (plastic ≤ 5 mm size). Although marine aquatic ecosystems primary focus microplastic pollution research, a growing body evidence suggests that terrestrial are equally at risk. Microplastic contamination reported various environments from several sources such as mulch, pharmaceuticals cosmetics, tire abrasions (tire wear particles), textiles industries (microfibers), sewage sludge, dumping. Recent studies suggest soil sink pollutants is often contaminated with mixture organic inorganic pollutants. This gradually caused adverse impacts on health fertility by affecting pH, porosity, water-holding capacity, microbial enzymatic activities. Microplastics can interact co-existing adsorbing contaminants onto their surfaces intermolecular forces, including electrostatic, hydrophobic, non-covalent, partition effects, van der Waals microporous filling mechanisms. subsequently delays degradation process existing contaminants, thereby ecological activities ecosystem.
