Macroplastics in rivers: present knowledge, issues and challenges

Environmental Science: Processes & Impacts, 2021
The contextualization of macroplastics in a budget framework can help to improve our understanding of the physical processes determining macroplastic behaviour and impacts in rivers. Hence, better management practices can be adopted.

Macroplastics at sea around Antarctica

Marine Environmental Research, 2010
More so than at any previous time, there is a heightened awareness of the amount of plastic in the environment, it's spread to even remote localities and the multiple influences of this on organisms. In the austral summer of 2007/08 Greenpeace and British Antarctic Survey ships (MV Esperanza and RRS James Clark Ross respectively) conducted the first co-

From Micro‐ to Macroplasticity

Advanced Materials, 2006
Therefore, macroplasticity theories based on amechanism involving long-range dislocation motion cannotserve to predict micro-yielding. In terms of measured stress–strain behavior, the two regimes are poorly distinguished,especially when they are characterized by positive strain-hard-ening, i.e., an increase in strength when the microstructure ...

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.
