Temporal stability of riverbank macroplastic

Abstract Macroplastic pollution (>0.5 cm) is prevalent on riverbanks and floodplains globally. Macroplastic can reach riverbanks via various pathways. These pathways include direct littering, overland transport by wind or surface runoff, or transport and deposition by the river.

Riverbank macrolitter in the Dutch Rhine–Meuse delta

Environmental Research Letters, 2020
Anthropogenic litter in aquatic ecosystems negatively impacts ecosystems, species and economic activities. Rivers play a key role in transporting land-based waste towards the ocean.

Generating Tagged Micro‐ and Nanoparticles of Poly(ethylene furanoate) and Poly(ethylene terephthalate) as Reference Materials

Macromolecular Rapid Communications, Volume 47, Issue 4, 20 February 2026.
We successfully developed poly(ethylene terephthalate) (PET) and poly(ethylene furanoate) (PEF) nanoparticles and microparticles, covalently tagged with Alexa Fluor 633 or Alexa Fluor 647, using both mechanical and solvent‐based approaches. The particles displaying hydrodynamic diameters between 200 and 700 nm, exhibited long‐term colloidal stability ...

Riverine macroplastic monitoring in Myanmar: sources and pollution dynamics in the Bago River

Microplastics and Nanoplastics
Global plastic pollution has been highlighted as an important environmental issue that requires urgent attention. Macroplastics, plastic items >2.5 cm, contribute the majority to global plastic pollution by mass and are the easiest to manage or remove ...

A Shape‐Based Model for Drag and Terminal Velocity of Non‐Spherical Plastic Particles

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Plastic pollution in rivers is governed by how individual particles move among the bed, the water column, and the free surface, processes that depend primarily on drag and terminal velocity. Although plastic particles span a much wider range of shapes than natural sediments, many existing drag and terminal‐velocity formulations still rely on ...

Riverine plastic emission from Jakarta into the ocean

Environmental Research Letters, 2019
Plastic pollution in aquatic environments is an increasing global risk. In recent years, marine plastic pollution has been studied to a great extent, and it has been hypothesized that land-based plastics are its main source.

Tracing macroplastics redistribution and fragmentation by tillage translocation

Journal of Hazardous Materials
Soil is polluted with plastic waste from macro to submicron level. Our understanding of macroplastics (> 5 mm) occurrence and behavior has remained comparatively elusive, mainly due to a lack of a tracing mechanism. This study set up a methodology to trace macroplastic displacement, which combined magnetic iron oxide-tagged soil and macroplastic pieces

The shapes and sizes of macroplastics and other litter in rivers

Environmental Science & Technology
Limited data exists on physical and geometric properties of river litter. To resolve this, we reveal the physical-structural relationships of river litter, using two of the most comprehensive datasets generated to date. First, we dissect the properties of river litter using a detailed dataset of over 14,000 riverbank items, for which their dimensions ...

Preferential deposition of macroplastic on floodplains

Abstract Floods have a large impact on the mobilization, distribution, and retention of plastic in rivers. During floods plastic transport in rivers increases, due to flushing of additional material into the river and (re-)mobilization of macroplastic previously deposited on floodplains and buried in the riverbed.

Diet and Feeding Behavior of the South Polar Skuas Stercorarius maccormicki in the Haswell Islands, East Antarctica

Birds
The diet and feeding behavior of South Polar Skuas (Stercorarius maccormicki) are well studied within the species’ breeding range but are poorly understood on the Haswell Islands. The aim of this study was to determine how South Polar Skuas use available
