Macroplastic fragmentation in rivers

Environment International, 2023
The process of macroplastic (>0.5 cm) fragmentation results in the production of smaller plastic particles, which threaten biota and human health and are difficult to remove from the environment.

Crowd-Based Observations of Riverine Macroplastic Pollution [PDF]

Frontiers in Earth Science, 2020
Macroplastic pollution (> 0.5 cm) negatively impacts aquatic life and threatens human livelihood on land, in oceans and river systems. Reliable information on the origin, fate and pathways of plastic in river systems is required to optimize prevention,

Macroplastic accumulation across different surface covers, a case study of two South African rivers [PDF]

Scientific Reports
Plastic pollution in freshwater ecosystems is an escalating global concern, yet riverine macroplastic pollution and dynamics remain poorly understood in Southern Africa. This study investigated macroplastic accumulation across different surface covers in

RiSID: River Surface Image Dataset for Instance Segmentation of Floating Macroplastic Debriszenodo [PDF]

Data in Brief
Rivers constitute a major pathway of macroplastic debris, which has the potential to have adverse impacts on marine ecosystems and oceans. It is essential to develop image-based technology for quantifying macroplastic debris floating on river surfaces ...

Quantification of macroplastic litter in fallow greenhouse farmlands: case study in southeastern hungary [PDF]

Environmental Sciences Europe, 2023
Background Plastic greenhouse farming has become widespread worldwide because of its contributions to various agricultural production. However, it also generates plastic waste in large quantities and pollutes farmlands.

Field experiment confirms high macroplastic trapping efficiency of wood jams in a mountain river channel [PDF]

Scientific Reports
Identifying macroplastic deposition hotspots in rivers is essential for planning cleanup efforts and assessing the risks to aquatic life and the aesthetic value of river landscapes.

Macroplastic distribution patterns and accumulation in an urbanised Austral subtropical river system [PDF]

Scientific Reports
Plastic products have resulted in enormous pollution in many ecosystem types and regions worldwide. The problem is particularly prominent within aquatic environments, where multiple anthropogenic sources (i.e., agriculture, urbanisation, industries ...

Harmful algae and pathogens on plastics in three mediterranean coastal lagoons [PDF]

Heliyon, 2023
Plastic is now a pervasive pollutant in all marine ecosystems. The microplastics and macroplastic debris were studied in three French Mediterranean coastal lagoons (Prevost, Biguglia and Diana lagoons), displaying different environmental characteristics.

First attempt to measure macroplastic fragmentation in rivers

Environment International
Direct field measurements of macroplastic fragmentation during its transport in rivers are currently unavailable, and there is no established method to perform them.

Wind- and rain-driven macroplastic mobilization and transport on land [PDF]

Scientific Reports
Wind and rain are considered main drivers for mobilization and transport of macroplastics on land, yet there is a lack of empirical data that quantifies this. We present lab experiment results on land-based macroplastic mobilization and transport.
