Lost in transportation - macroplastic retention in rivers

Rivers are dynamic systems disrupted by numerous physical structures such as dams, locks, bridges, and reservoirs. These discontinuities hinder hydrological connectivity and lead to the retention of water-borne materials. While such retention is well-documented for sediment, nutrients, and large wood, its role in macroplastic transport has only ...

Quantifying Sources, Sinks and Mitigation of Macroplastic and Other River Debris: A Trash Balance Model

Earth's Future
Mismanaged consumer plastics and other waste that enters a river system, known as riverine debris, is a pervasive problem in urban rivers with consequences for ecosystem health and human livelihood. A better understanding of the loading pathways, fluxes,

Model Prediction of Macroplastic Distributions in European Marine Basins: Comparison with Beach and Floating Macroplastic Observations and Estimation of Model Accuracy

Oceans
Accumulation of plastic litter in the marine environment is a pressing global concern. To study this issue, we use the Blue2 Modelling Framework (Blue2MF), an integrated modelling tool developed by the Joint Research Centre (JRC) of the European ...

Plastic pollution and water hyacinths consistently co-occur in the lower Saigon river

Environmental Research: Water
Plastic pollution is an emerging entity threatening freshwater and marine ecosystems. Rivers play an important role in the transport and retention of plastic between land and sea.

Does macroplastic really concern the fisherman? - An insight into the Norwegian fishing industry's macroplastic management today and in the future

How does macroplastics actually concern the fisherman? That is the question that this qualitative research of the fishing industry along the Norwegian coast aims to answer by interviewing Norwegian fishermen as well as observing their methods for macroplastic pollution mitigation.

A transport and accumulation model for macroplastics in rivers

ABSTRACT: We present a novel model that simulates macroplastic transport and retention in rivers, and which explicitly considers plastic accumulation in floodplains. The modelling ap-proach is based on a simplified representation of flow distributions between river channel and floodplains in non-uniform compound channels.

The Circularity Assessment Protocol in Cities to Reduce Plastic Pollution

Community Science
The circular economy has been promoted as a solution to plastic pollution, but cities and communities bear the brunt of plastic pollution. The Circularity Assessment Protocol (CAP) is a systems method of collaborative and open data collection for ...
