“…The interactive migration model of external environmental factors, internal water characteristics, and the physical and chemical properties of microplastics can be constructed. Systematic research can be carried out on multiple factors and scales to have a more comprehensive understanding of the migration process of microplastics in the real environment and better supervise their ecological risks [126,169]. At the same time, large-scale data acquisition needs to be standardized before validating the migration model to increase the applicability of measurements.…”

Microplastics are widely present worldwide and are of great concern to scientists and governments due to their toxicity and ability to serve as carriers of other environmental pollutants. The abundance of microplastics in different water bodies varied significantly, mainly attributed to the initial emission concentration of pollutants and the migration ability of pollutants. The migration process of microplastics determines the abundance, fate, and bioavailability of microplastics in water. Previous studies have proved that the physicochemical properties of water bodies and the properties of microplastics themselves are important factors affecting their migration, but the change in external environmental conditions is also one of the main factors controlling the migration of microplastics. In this paper, we focus on the effects of meteorological factors (rainfall, light, and wind) on the distribution and migration of microplastics and conclude that the influence of meteorological factors on microplastics mainly affects the inflow abundance of microplastics, the physical and chemical properties of water, and the dynamics of water. At the same time, we briefly summarized the effects of aquatic organisms, water substrates, and water topography on microplastics. It is believed that aquatic organisms can affect the physical and chemical properties of microplastics through the physical adsorption and in vivo transmission of aquatic plants, through the feeding behavior, swimming, and metabolism of animals, and through the extracellular polymers formed by microorganisms, and can change their original environmental processes in water bodies. A full understanding of the influence and mechanism of external environmental factors on the migration of microplastics is of great theoretical significance for understanding the migration law of microplastics in water and comprehensively assessing the pollution load and safety risk of microplastics in water.

“…To solve single-use plastic waste equitably, countries should give full play to the effectiveness of the Basel convention and find room for improvement on this basis. The Basel Convention and its amendments stipulate that the state parties to the convention enjoy the right to treat marine plastic waste and the direct basis for the treatment of marine plastic waste [11] , which has a significant impact on the global prevention and control of marine plastic waste pollution. In terms of effectiveness, more member states should be encouraged to abide by their commitments and participate deeply.…”

Plastic has brought great convenience to people’s lives, but it has also brought severe environmental pollution to the world. It is almost impossible to break down entirely in nature, and plastic waste, whether in rivers, oceans, or on land, can persist in the environment for centuries. The problem of plastic waste disposal has caused worldwide concern. It is necessary to reduce the production of plastic products through global cooperation effectively. However, achieving this goal will also involve some unexpected issues, such as controlling the adverse economic impact of plastics, and the rationality and fairness of the distribution of responsibilities between different countries. This paper collects massive data and takes China as an example to study the impact of plastic output reduction on China’s Express industry and the plastics manufacturing industry using multivariate regression. This paper summarizes the positive and negative effects of plastic waste reduction. Given the distribution and management of national and regional plastic waste responsibilities, the global carbon emission rights distribution method is used for reference. The comprehensive index allocation method is used to deal with the problem of both fairness and efficiency relatively. What is more, based on the conclusions, this paper also provides suggestions for a global joint response to plastic waste.

“…The rapid increase in production and consumption of plastic materials has resulted in large amounts of plastic waste being released into the environment; of the 400 million tons of plastic waste that is generated worldwide, only 9% is recycled, 10.3389/feart.2024.1349865 while about 80% accumulates in landfills or remains mismanaged and may end up in the natural environment (Amobonye et al, 2021;OECD, 2022;Haque and Fan, 2023;Lamichhane et al, 2023). It is estimated that up to 14 million tons of plastic waste end up in the ocean annually, making up 50%-80% of all marine debris that accumulates globally, of which 70%-80% are from land-based sources such as rivers, stormwater runoff, wastewater discharges, or transport of land litter by wind (Jambeck et al, 2015;Chaturvedi et al, 2020;Watt et al, 2021).…”

Micro- and nanoplastics in freshwater ecosystems—interaction with and impact upon bacterivorous ciliates

The ubiquitous occurrence of microplastics and nanoplastics in aquatic environments is of major concern as these priority pollutants are readily ingested by a wide variety of aquatic organisms. Although quantitative data on the interaction of microplastics and even more so on nanoplastics in freshwater environments and their interaction with the aquatic food web are still limited, studies have nevertheless demonstrated that even micro- or nanosized plastic particles can be ingested by various members of the zooplankton functioning as primary consumers. Bacterivorous ciliates are crucial members of the microzooplankton. These fascinating microorganisms are critical components of microbial loops in freshwater environments and are essential links between different trophic levels within the aquatic food web. Ingestion of microscopic plastic particles affects the ciliate cell on a cellular and even on the molecular level. Physical and chemical characteristics such as size, density, and surface properties influence the stability, distribution, retention, transportation, and bioavailability of the microplastic particles for ingestion by ciliates. In turn, the environmental fate of microplastics and nanoplastics can affect their ecotoxicity via surface modifications, such as forming the so-called eco-corona. The consequences of the interaction of ciliates with microplastics and nanoplastics are the potential bioaccumulation of plastic particles through the food web and the possible interference of these emerging pollutants with controlling bacterial and possibly even viral abundance in freshwater environments. Due to the limited data available, studies elucidating the environmental bacterivorous ciliate-micro-/nanoplastics interaction are a priority research topic if we want to holistically assess the environmental fate and ecotoxicity of these pollutants.
