“…254,255 MP mitigation approaches are classified depending on their removal characteristics, including filtration and separation, capture and surface attachment, and degradation. 256 Biodegradable plastics are an appropriate solution to this global concern because they decompose into carbon dioxide and water in 20−45 days in the presence of enough oxygen, microorganisms, and humidity. 257 Several strategies have been developed to program the lifetime of degradable polyethylene, including the incorporation of weak sites such as carbonyl groups or double bonds into the hydrocarbon backbone or side chains during polymerization.…”

“…Only MPs smaller than 20 μm can enter organs, and MPs in the range of 10 μm could access all organs and cross cell membranes, the blood-brain barrier, and enter the placenta. The potential effects of MPs on human health may be due to their size, shape, chemical composition, concentration, or microbial biofilm growth. , MP mitigation approaches are classified depending on their removal characteristics, including filtration and separation, capture and surface attachment, and degradation .

Polyolefins play a crucial role in the polymer industry because of their low-cost monomers and well-established production processes. Recent years have witnessed tremendous progress in direct and tandem copolymerization strategies that provide an opportunity of developing polyolefins bearing polar groups with distinctive architectures and properties. In this perspective, we first highlight new routes for the proficient synthesis of tailor-made functional polyolefins and briefly discuss their designing tactics. Then, we attempt to categorize these, recently appeared in the literature, innovative functional polyolefins on the basis of their applications. The prospected future applications of polar olefin copolymers include biomedical materials, catalysts, energy storage devices, and conductive polymers, which open up new arenas and paradigms for academic research and industrial products development. Critical issues concerning intelligent functional polyolefins and green chemistry are discussed, too.

Coronas of micro/nano plastics: a key determinant in their risk assessments

et al. 2022

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

“…Under this context, Wastewater Treatment Plants (WWTPs) have been identified as one of the main dominant sources of MPs in freshwater [7]. The MPs found in wastewaters consist for example of microbeads added in peeling lotions and toothpastes and synthetic fibers from textile and clothing [4]. In general terms, studies have indicated that wastewater treatments plants remove the majority of MPs, achieving removal efficiencies of 98-99% [8,9].…”
