“…Between March 2018 and April 2019, 418 Microlax were recorded as stranded litter on the river banks. They were always found together with other plastic debris such as expanded polystyrene, cotton swabs, lollipop sticks, syringes and other unidentified plastic fragments that are common on riverbanks in the Seine estuary (Tramoy et al, 2019). Among the 418…”

“…Consequently, rivers, and estuaries in particular, may function as a "microplastic factory" resulting from the fragmentation of macroplastics after weeks to years of transport/deposit cycles on riverbanks. Although, there is still a lack of evidence linking the concentration in microplastics in water and the fragmentation of macroplastics, unidentified fragments of plastics are one of the main contributors of the plastic pollution on riverbanks in the Seine estuary (Tramoy et al, 2019).…”

Rivers are a major pathway for plastics between lands and the ocean. At the land-ocean interface, estuaries make the transfer dynamic of plastics complex and nonlinear. That is why very little is known about this dynamic. In this respect, a specific marker (i.e. Microlax packaging) showing date-prints was systematically investigated in different riverbanks of the Seine estuary to identify the share of "old" and "recent" litter transiting through the estuary toward the ocean. Up to 70% of Microlax were "old" plastic items probably related to the meandering dynamic of the river over large time and space scales, and hydrodynamic conditions (tides) at smaller scales. This contributes together to increase the residence time of plastics into the estuary up to decades with almost endless transport, deposit and remobilization cycles. Consequently, the Seine estuary may function as a "microplastic factory" resulting from the fragmentation of macroplastics into microplastics well before they reach the ocean.

“…First, unlike van der Wal et al (2015), this method does not require large equipment such as cranes, boats and sampling equipment. Instead, plastic statistic can be gathered using infrastructure that is already in place such as the Shoreliner, or by gathering samples at natural collection zones such as riverbanks, weirs and sluices (Tramoy et al, 2019a). Because of this, the rapid assessment method can be applied using less resources.…”

<p>Most marine litter pollution is assumed to originate from land-based sources, entering the marine environment through rivers. To better understand and quantify the risk that plastic pollution poses on aquatic ecosystems, and to develop effective prevention and mitigation methods, a better understanding of riverine plastic transport is needed. To achieve this, quantification of riverine plastic transport is crucial. Here, we demonstrate how established methods can be combined to provide a rapid and cost-effective characterization and quantification of floating macroplastic transport in the River Rhine We combine visual observations with passive sampling to arrive at a first-order estimate of macroplastic transport, both in number (10 - 75 items per hour) and mass per unit of time (1.3 &#8211; 9.7 kg per day). Additionally, our assessment gives insight in the most abundant macroplastic polymer types the downstream reach of the River Rhine. Furthermore, we explore the spatial and temporal variation of plastic transport within the river, and discuss the benefits and drawbacks of current sampling methods. Finally, we present an outlook for future monitoring of major rivers, including several suggestions on how to expand the rapid assessment presented in this paper.</p>

“…One of the first studies to quantify plastic pollution in river systems was done by Williams and Simmons (), who counted the number of plastic items along the Cynon river (UK). Several other studies only reported the amount of collected samples, as the main interested was often to analyze the polymer type of item class (Morritt et al, 2014; Tramoy, Colasse, Gasperi, & Tassin, ). Most studies focusing on riverbank plastics reported their results in items or mass per unit of surface area, with a maximum density of 400 items/m 2 measured in the Adour river, France (Bruge et al, ).…”

Plastic pollution in aquatic ecosystems is an emerging environmental risk, as it may negatively impacts ecology, endangers aquatic species, and causes economic damage. Rivers are known to play a crucial role in transporting land‐based plastic waste to the world's oceans, but riverine ecosystems are also directly affected by plastic pollution. To better quantify global plastic pollution transport and to effectively reduce sources and risks, a thorough understanding of origin, transport, fate, and effects of riverine plastic debris is crucial. In this overview paper, we discuss the current scientific state on plastic debris in rivers and evaluate existing knowledge gaps. We present a brief background of plastics, polymer types typically found in rivers, and the risk posed to aquatic ecosystems. Additionally, we elaborate on the origin and fate of riverine plastics, including processes and factors influencing plastic debris transport and its spatiotemporal variation. We present an overview of monitoring and modeling efforts to characterize riverine plastic transport, and give examples of typical values from around the world. Finally, we present an outlook to riverine plastic research. With this paper, we aim to present an inclusive and comprehensive overview of riverine plastic debris research to date and suggest multiple ways forward for future research.
