“…With the plastic flux p [items min −1 ] for each segment i, the total counted plastic items C [items] in section i, and the measurement duration T [min] at section i. The total plastic flux over the entire river width P is expressed in items hour −1 , the most commonly used unit (e.g., Castro-Jiménez et al, 2019;van Calcar and van Emmerik, 2019;Schirinzi et al, 2020). Plastic flux in downstream direction is noted as positive, and plastic flux in upstream direction is noted as negative.…”

“…In combination with extensive coastal zone and short distance between population and river systems, the Philippines is assumed to have the highest national plastic emissions from rivers into the ocean (Meijer et al, 2019). Rivers traversing densely populated urban areas, such as the Philippines' capital Metropolitan Manila, are expected to export high amounts of plastic waste from land into the ocean (van Emmerik et al, 2019b;Schirinzi et al, 2020). The Pasig, Tullahan and Meycauayan rivers, three of the main rivers flowing through Metropolitan Manila, all feature in the model-based global top five of the most plastic emitting rivers (Meijer et al, 2019).…”

“…Recently, van Calcar and van Emmerik (2019) demonstrated that the magnitude, temporal variation, and typical composition of riverine macroplastics varies greatly between rivers. Available long-term observations studies revealed that many rivers exhibit a strong seasonality in macroplastic transport (Castro-Jiménez et al, 2019;van Emmerik et al, 2019b;Schirinzi et al, 2020). Composition of plastics is important to identify potential waste sources (consumers or industry), and transport mechanisms from land into river systems (natural or anthropogenic).…”

“…The temporal dynamics of the plastic load is less well understood, as most observational studies are single instance measurements or measurements over a very short period of time 12 . The rst observational studies over longer periods have hinted at a strong link between discharge and the amount of plastic in the river [14][15][16] . This naturally leads to the question about the importance of extreme discharge events.…”

Riverine plastic pollution is of global concern due to its negative impact on ecosystem health and human livelihood. Recent studies show a strong link between river discharge and plastic transport, but the role of floods is still unresolved. We combined high resolution mismanaged plastic waste data and river flood extents with increasing return periods to estimate flood-driven plastic mobilisation, aggregated at administration unit, country and global scale. We show that 10-year return period floods already tenfold the global plastic mobilisation potential compared to non-flood conditions. In the worst affected regions, plastic mobilisation increases up to five orders of magnitude. Our results suggest a high inter-annual variability in plastic mobilisation, previously ignored by global plastic transport models. Flood defences reduce plastic mobilisation substantially, but regions vulnerable to flooding often coincide with high plastic mobilisation potential during floods. Consequentially, clean-up and mitigation measures and flood risk management are inherently interdependent and need to be managed holistically.

The Way of Macroplastic through the Environment

et al. 2020

With the focus on microplastic in current research, macroplastic is often not further considered. Thus, this review paper is the first to analyse the entry paths, accumulation zones, and sinks of macroplastic in the aquatic, terrestrial, and atmospheric environment by presenting transport paths and concentrations in the environment as well as related risks. This is done by applying the Source–Pathway–Receptor model on macroplastic in the environment. Based on this model, the life cycle of macroplastic is structurally described, and knowledge gaps are identified. Hence, current research aspects on macroplastic as well as a sound delimitation between macro- and microplastic that can be applied to future research are indicated. The results can be used as basic information for further research and show a qualitative assessment of the impact of macroplastic that ends up in the environment and accumulates there. Furthermore, the applied model allows for the first time a quantitative and structured approach to macroplastic in the environment.
