“…In addition to the extensive applied Lagrangian particle-tracking oceanic models summarized in ref. 127 , some other particle-tracking models have also been applied to microplastic transport simulations in coastal and estuarine regions, for instance the three-dimensional hydrodynamic and suspended sediment transport model (HYDROTAM-3D) 129 , Track Marine Plastic Debris (TrackMPD) 130 , the Delft3D-Water Quality Particle tracking module (D-WAQ PART) 131 and the ichthyoplankton dynamics tracker (Ichthyop) 132 . Unlike the Lagrangian approach, Eulerian models simulate microplastics as passive tracers in terms of their mass or volume concentrations, which are advected by the velocity fields and diffused by the parameterized turbulence 133 .…”

An estimated 19-23 million metric tons (MT) of land-based mismanaged plastic waste entered aquatic ecosystems in 2016 1 . More than 90% of mismanaged plastic waste is expected to be transported via watersheds (>100 km 2 ), suggesting that rivers are major pathways for plastics to the ocean 2 . Indeed, the estimated annual riverine plastic load into the global ocean is 0.8 to 2.7 million MT (ref. 3 ), as much as 50% of land-based plastic emissions (4.8-12.7 million MT) 4 . In the environment, natural fragmentation processes 5 break plastic waste into smaller pieces (<5 mm) of various sizes, shapes, colors and chemical composition 6 , collectively termed microplastics. As the environmental plastic load rises in the coming decades 7 , exposure of aquatic organisms to microplastics and associated chemicals will increase.Estuaries, which lie at the intersection of rivers and sea, accumulate pollutants including riverine plastic debris [8][9][10][11] . A notable accumulation hotspot is related to the formation of density fronts in estuarine system, where two distinct water masses interact and form sharp density transitions 12,13 . Estuarine fronts

Plastic pollution in aquatic ecosystems has been identified as a growing global water pollution threat that is negatively impacting water quality and, as a result, affecting the health of humans, aquatic animals, and wildlife. Therefore, it presents a global environmental catastrophe that requires immediate attention. Plastics in water (in their different forms, macro-, meso-, micro-, and nanoplastics) are contaminants of emerging concerns that have since evolved to be a global environmental threat. Despite increasing levels of pollution in aquatic ecosystems, there are insufficient monitoring data to evaluate the extent of the catastrophe. Traditional methods of monitoring plastics in water are constrained by high sampling costs, intensive labor, and limited temporal and spatial coverage, which results in limited monitoring data. Thus, insufficient monitoring data limit our understanding of the true quantities and persistence of plastic particles in aquatic ecosystems, as well as the extent to which they impact the aquatic environment. There is increasing availability of free big geospatial data (amounting to petabytes/day) from satellite sensors for potentially monitoring plastics. This provides a possible solution to these challenges by minimizing the fieldwork required and therefore reducing the costs and sampling time. The study purpose of this review is to analyze advances in emerging technology such as the use of satellite sensors to monitor the occurrence of macro- and microplastics in freshwater, ultimately aimed at creating new operational monitoring solutions. This review: (1) examines the literature to identify trends, accomplishments, and limitations of using satellite data to monitor plastics in water; (2) identifies and compares traditional, and machine and deep learning satellite image classification methods for monitoring plastics in water; and (3) identifies research gaps and summarizes future perspectives and recommendations to improve monitoring methods.

：Microplastics are ubiquitous in various environmental media on a global scale, and can adsorb co-existing pollutants, especially organic pollutants, thus changing the environmental behavior and toxicity of pollutants; they can also promote the migration of pollutants in different media through adsorption/desorption. Influencing factors and mechanisms of adsorption between microplastics and organic pollutants are necessary information for a comprehensive assessment of the environmental risks of microplastics and organic pollutants. Due to the complexity of composition, structure and surface characteristics of microplastics and the diversity of co-existing organic pollutants, the interaction between them is very complex. Based on a review of the relevant literatures in recent years, the authors systematically summarized the current status of occurrence and migration of microplastic in environmental media, the influencing factors of microplastic adsorption of organic pollutants and their interaction mechanisms, with a view to providing useful references for the in-depth understanding of the environmental behavior and ecological risks of microplastics.
