“…Combined exposure to PS MPs and Cu 2+ led to oxidative damage and inflammation in fish tissues and embryos, but the combination of Cd 2+ and MPs had few toxic effects [ 146 ]. In mammalian systems, while free ions mainly pass through plasma membranes via ion channels or passive distributions and react with cytoplastic proteins [ 147 ], metal ions in the corona are internalized into lysosomes by endocytosis and interact with lysosomal proteins [ 148 ]. The persistent feature of M/NPs restricted the elimination of metal ions from the organism [ 149 ], resulting in prolonged bioavailability.…”

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.

“…Te pore-flling process depends on the polymer structure, particularly its pore diameter, and also on the molecular size of the pollutant/chemical. During the poreflling process, the contaminants enter the polymer matrix and get trapped in the small pores of microplastics, and pollutants with lower molecular weight are found to move easily through the polymer matrix with larger pores [47,48]. Laboratory and feld studies show that MPs can adsorb chemicals ranging from 1 to 10,000 ng/g [49].…”

Plastic pollution is not at all a novel matter to the scientific as well as the public community. However, the knowledge of the general public when it comes to microplastic pollution is still in its infancy. The major sources of these tiny plastic particles in the aquatic environment are laundry, abrasion of household plastics, cosmetics, personal care products, tyre wear, food wrappings, and so on. However, the public is not much aware that they are part of these major emission sources and how much they are contributing to it. Also, the vast majority of research conducted to date on plastic pollution in all size fractions has focused more on marine ecosystems than freshwater ecosystems. Hence, people are more associated with freshwater ecosystems than marine ecosystems; it should be given additional importance.Rather than the effect on aquatic organisms through ingestion and other ways, the ecological risks posed by micro and nanoplastics as vectors for chemical contaminants and their accumulation through trophic transfer are more serious and of utmost importance. Aquatic life or aquatic ecosystem is already affected by a multitude of environmental stressors, and now microplastics and nanoplastics may represent a significant additional risk to food security. Micro and nanoplastics have already invaded our diet in various ways. Even if it does not show any immediate effect on human health, long-term exposure may pose a serious threat to the human population. Hence, identifying the possible sources and reducing exposure to these sources is of utmost importance.

“…It is noteworthy that contaminants can desorb from or remain attached to NPs after bioaccumulation. The increased uptake of pollutants by plants was attributed to increased bioavailability of NPs and coexisting pollutants, resulting plant cell membrane damage, leading to increased uptake of pollutant‐bound NPs and subsequent NPs desorption (Maity et al, 2021). In contrast, the reduced uptake of pollutants by plants is attributed to the adsorption of co‐occurring pollutants to the surface of NPs, thus reducing bioavailability (Davranche et al, 2019).…”

Nanoplastics (NPs) are accumulating in the soil environment at a rapid rate, which may cause serious consequences for ecosystems and human health. However, environmental behaviour and toxicity of NPs in the soil-plant system remain poorly understood. This review summarizes current studies on NP-plant interactions to unravel uptake mechanisms and phytotoxicity of NPs. NPs could be taken up by plant roots and transported upwards through the xylem to all organs of the plant, even to the edible parts such as the grain, thereby threatening human health.The interaction of NPs with plants affects plant transport of water and nutrients.Besides, it induces significant oxidative stress leading to inhibition of physiological and biochemical activities such as photosynthesis, and thus adversely affects plant growth and development. In addition, the co-transport of NPs with other soil pollutants may induce the combined toxic effects. This study also discussed the potential mechanism of NP-plant interactions based on previous experience with engineered nanomaterials. Finally, a comprehensive assessment of the key challenges in each area was presented, and future perspectives are offered.
