Microplastic addition has no detectable effect on ecosystem metabolism or diel dinitrogen flux in a large in‐lake mesocosm experiment under oligotrophic conditions

Limnology and Oceanography, Volume 71, Issue 5, May 2026.
Abstract Ecosystem metabolism (e.g., gross primary production [GPP], respiration [R], and net ecosystem production) integrates the activity of aerobic organisms and is an indicator of environmental change. Microplastics (i.e., particles 1–5 mm) are widespread in freshwater ecosystems and are colonized by biofilms and other organisms.

Suitability of river plastic monitoring methods for citizen science

Cambridge Prisms: Plastics
Rivers act as long-term plastic storage and a pathway for land-based plastic pollution into the ocean. Monitoring river plastic at a global scale remains challenging, with only limited large-scale and long-term monitoring efforts to date. Citizen science

Microplastic Detectability Investigation in Soils Using X‐Ray Microtomography

X-Ray Spectrometry, Volume 55, Issue 3, Page 387-398, May/June 2026.
ABSTRACT X‐ray microtomography (microCT) is a promising tool for investigating microplastic (MP) contamination in soils, offering non‐destructive 3D visualization and quantitative analysis of particles embedded in complex matrices. This study evaluated its applicability by mixing plastic fragments (PET, PEHD, PS, and PP) with humus‐rich and sandy soils

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, Volume 28, Issue 7, 8 April 2026.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Exploring the Transferability of Image‐Based Algorithms for River Plastic Detection: The Value of Small Mixed Data Sets

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Using large image data sets has been the conventional strategy to improve object detection, but it increases annotation effort and training cost and does not guarantee robust transfer to new sites. Here we quantify the value of a small, diverse training set for floating macroplastic detection by jointly evaluating performance, computational ...

Pollution to Solution: Understanding and Addressing Microplastic Contamination in the Environment

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT In general, plastic pollution results from the unintentional release of macroplastic materials into the environment as well as the deliberate production and usage of small plastic particles (micro‐ and nano‐sized plastic particles) in a variety of consumer products micro and nanoplastics in filtrate freshwater and marine environments because ...

No escape from microplastics: Contamination of reef manta ray feeding areas in a remote, protected archipelago

Conservation Science and Practice, Volume 8, Issue 3, March 2026.
We found microplastic contamination of the upper water column around the Chagos Archipelago, a remote, protected archipelago in the central Indian Ocean. Key aggregation areas for reef manta rays (Mobula alfredi) were contaminated, putting them at risk of microplastic ingestion.

Preferential deposition of macroplastic on floodplains

Cambridge Prisms: Plastics
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.

Same but Different: A Framework to Design and Compare Riverbank Plastic Monitoring Strategies

Frontiers in Water, 2020
Plastic pollution in rivers negatively impacts human livelihood and aquatic ecosystems. Monitoring data are crucial for a better understanding of sources, sinks and transport mechanisms of riverine macroplastics.
