Linking macroplastic deposition to riverbank characteristics

2023
Rivers transport, and store a large share of the global plastic pollution. Riverbanks are one of the river compartments where macroplastic litter is deposited and retained. Different factors influence macroplastic deposition on riverbanks. Retention related factors such as riverbank features, and supply related factors, such as hydrometeorology or land-

Rising and settling velocities of macroplastic foils

2022
<p>Plastics accumulate in the environment due to inadequate waste management, and the durability of the material. A better understanding of fundamental plastic behaviour in the aquatic environment is essential to estimate transport and accumulation, which can be used for monitoring, prevention and reduction strategies.

Endless journey of macroplastics in rivers

2020
Rivers are supposed to be the main pathways of plastics from lands into the Ocean (Lebreton et al., 2017; Schmidt et al., 2017). However, there is still a huge lack of knowledge on how riverine litter, including macroplastics, is transferred into the Ocean. Quantitative measurements of macroplastic emissions in rivers even suggest that a small fraction

Soil denitrification stimulated by macroplastics in maize cultivation

Journal of Hazardous Materials
Macroplastics (plastic debris > 2 cm) represent an understudied but increasingly prevalent pollutant in agricultural soils, where they may disrupt nitrogen (N) cycling through physical interference with soil structure, altered microbial communities, and changes in nutrient dynamics.

Riverine Macroplastics and How to Find Them

2020
<p>Macroplastic (>0.5 cm) pollution in aquatic environments is an emerging environmental risk, as it negatively impacts ecosystems, endangers aquatic species, and causes economic damage. Rivers are known to play a crucial role in transporting land-based plastic waste into the world’s oceans.

Temporal stability of macroplastic on Dutch riverbanks

Is the distribution of macroplastic along rivers stable over time? Rivers transport and accumulate macroplastic litter, and large amounts of macroplastic are deposited on riverbanks. It seems there are factors and variables linked to macroplastic deposition at a specific location, e.g. riparian vegetation or population density.

Detached groynes impact on macroplastic transport

Experiments in laboratory channel were conducted in order to investigate the behavior of macroplastic particles in form of cut polypropylene cups flowing through a channel with groynes on one side. In the first scenario groynes were attached to the flume’s wall.
