ClearMicroplastic accumulation, depuration dynamics and localization in environmental compartments: combination of experimental set ups and field studies
Researchers used microcosm experiments to track microplastic accumulation, depuration, and tissue localization in marine organisms under environmentally relevant conditions. The study found that organisms can accumulate and partially depurate microplastics, with particle retention varying by tissue type and particle size.
Understanding the influence of biota in the transfer of different sized microplastics between environmental compartments of marine ecosystem
This study investigated how marine micro- and macro-biota influence the transport of microplastics between environmental compartments such as water, sediment, and organisms, finding that biological interactions substantially alter the distribution of particles beyond what hydrodynamics alone would predict.
The fate of microplastic in marine sedimentary environments: A review and synthesis
A systematic review of 80 papers on microplastics in marine sediments found median concentrations varied widely by sediment environment, with fibers dominating many locations, and showed that sediment grain size and organic carbon content influence microplastic accumulation.
Beyond the exposure phase: Microplastic depuration and experimental implications
This review systematically analyzed studies of microplastic depuration in aquatic organisms, focusing on how long plastic particles are retained after exposure ends. The authors found that depuration kinetics vary by species, particle size, and polymer type, and that current studies inadequately characterize post-exposure clearance.
Microplastics spatiotemporal distribution and variability in marine habitats along the North-Western Mediterranean coastal waters.
Researchers assessed microplastic spatiotemporal distribution across multiple Mediterranean marine habitat types including water surface, sediment, and biota, revealing significant variability by location and season. The multi-compartment approach showed that no single habitat type captures the full extent of microplastic contamination.

The fate of plastic litter within estuarine compartments: An overview of current knowledge for the transboundary issue to guide future assessments
Researchers reviewed global knowledge on plastic fate within estuaries and found plastic concentrations reaching thousands of items per cubic meter in water and sediment, while identifying major methodological gaps — particularly that microfibers are consistently undersampled and that studies rarely account for ecological trophic gradients or the physicochemical dynamics driving plastic distribution and bioavailability.
Dispersion, accumulation and the ultimate fate of microplastics in deep-marine environments: A review and future directions
This review synthesized existing knowledge on microplastic distribution in deep-marine environments, integrating process-based sedimentological transport models with field data to outline how microplastics disperse, accumulate, and become buried in seafloor sediments, and identifying key gaps for future research.
Modelling the sedimentation of macro-, micro- and nanoplastics in the ocean from surface to sediment
Researchers modeled the sedimentation of macro-, micro-, and nanoplastics from the ocean surface to the seafloor, finding that biofouling and particle aggregation dramatically accelerate sinking rates and that most plastics eventually reach benthic environments.
Distinct microplastic patterns in the sediment and biota of an urban stream
Researchers found distinct microplastic contamination patterns between sediments and aquatic biota in an urban stream, with sediments accumulating more particles while biota showed selective uptake based on particle size and shape, highlighting the complex dynamics of microplastic distribution in urban freshwater systems.
Sediment matters as a route of microplastic exposure: A call for more research on the benthic compartment
Researchers conducted a systematic review highlighting that most microplastic studies focus on pelagic species in water-only exposures, despite evidence that sediment acts as a major sink for marine microplastics. The study calls for more research on sediment as an important exposure pathway for benthic invertebrates, recommending ecologically relevant concentrations and durations in future experiments.
