Trapped microplastics within vertical redeposited sediment: Experimental study simulating lake and channeled river systems during resuspension events

Researchers simulated sediment resuspension events to study how microplastics of different densities, sizes, and shapes become trapped within redeposited sediment layers, finding that particle properties strongly influence vertical redistribution patterns in lake and river systems.

Extraction of microplastics from sediment matrices: Experimental comparative analysis

Extraction efficiencies of four methods for separating microplastics from sediment matrices were experimentally compared using spiked samples, finding that density separation with saturated NaCl was adequate for most polymer types but underperformed for high-density polymers, and that no single method achieved complete recovery across all particle sizes and shapes.

Reactivity of selected model microplastics with ozone

Researchers conducted the first laboratory study on the reactivity of model microplastics — PEEK, PTFE, LDPE, and PET — with atmospheric ozone, finding that ozone alters the surface chemistry of these plastics in ways that could affect their environmental fate and potential to carry other pollutants.

A Streamlined Protocol for Comprehensive Anthropogenic Particles and Microplastic Characterization in Canal Sediments: From Concentrations to Environmental Drivers

Scalable Production of Multifunctional Bio‐Based Polyamide 11/Graphene Nanocomposites by Melt Extrusion Processes Via Masterbatch Approach

Researchers developed a scalable process to make bio-based polyamide 11 plastic reinforced with graphene, improving its electrical conductivity and mechanical strength by up to 56%. This is a materials engineering study on new polymer composites, not directly related to microplastic environmental impacts.

Polymorphic microsatellite markers demonstrate hybridization and interspecific gene flow between lumbricid earthworm species, Eisenia andrei and E. fetida

This study used microsatellite genetic markers to examine hybridisation between two closely related composting earthworm species, Eisenia andrei and E. fetida, finding significant interspecific gene flow. While focused on genetics, these species are commonly used as model organisms in microplastic soil toxicity testing.

Assessing the real concentrations of microplastic and their actual effects on marine biota

This conference paper assesses the real concentrations of microplastics in marine environments and examines their actual effects on marine organisms, reviewing discrepancies between laboratory exposure studies and field-realistic conditions.

Prospective study on macroplastics and microplastics in dredging sediments

This conference presentation examines microplastics and macroplastics found in river dredging sediments, assessing contamination levels and implications for sediment management. The study is presented at an international audience and contributes to understanding how plastic pollution accumulates in river sediments subject to dredging activities.
