ClearThe legacy effect of microplastics on aquatic animals in the depuration phase: Kinetic characteristics and recovery potential
A meta-analysis of microplastic depuration studies across 68 kinetic curves from aquatic animals found that many species retain a fraction of ingested MPs even after prolonged exposure-free periods, with retention rates and recovery timelines varying by species and MP type. The findings highlight the legacy effects of microplastic exposure that persist after contamination ends.
Microplastic 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.
Microplastic accumulation, depuration dynamics and localization in environmental compartments: combination of experimental set ups and field studies
Researchers tracked microplastic accumulation and depuration in multiple environmental compartments and marine organisms using controlled microcosm experiments. The study found that particles distribute differently across sediment, water, and biota, and that biological depuration is incomplete within realistic timeframes.
Uptake and depuration kinetics of microplastics with different polymer types and particle sizes in Japanese medaka (Oryzias latipes)
Researchers studied the uptake and depuration kinetics of microplastics with different polymer types and sizes in Japanese medaka fish. They found that smaller particles accumulated more readily in fish tissues and were retained longer than larger ones, with particle distribution varying by organ. The study provides important quantitative data on how microplastic characteristics influence their accumulation and clearance in fish, which is relevant to understanding food chain transfer.
Microplastics in aquatic environments: Occurrence, accumulation, and biological effects
This review compiled evidence on microplastic occurrence, accumulation, and biological effects in global aquatic environments, covering uptake by organisms across trophic levels and the role of microplastics as vectors for persistent organic pollutants. The authors highlight concentration-dependent toxicity and the need for ecologically relevant exposure scenarios in laboratory studies.
Microplastics in aquatic environments: a review of recent advances
This review synthesizes recent advances in understanding microplastic contamination in aquatic environments, covering sources, distribution, and physical, chemical, and biological removal methods, and highlighting that no standardized cost-effective removal solution currently exists. The review emphasizes that microplastics cycle through natural and engineered systems, requiring whole-system approaches to avoid unintended recontamination.
A Global Perspective of Beginning to the End of the Microplastics in the Aquatic Environment
This comprehensive review examines microplastics in aquatic environments from initial release through environmental fate, biological uptake, and ecological effects, identifying key knowledge gaps in freshwater and marine ecosystems.
Microplastic evacuation in fish is particle size‐dependent
Microplastic retention time in fish was found to depend on particle size, with larger particles being evacuated more slowly than smaller ones, providing empirical data to interpret gut burden studies and better understand chronic exposure dynamics.
A critical viewpoint on current issues, limitations, and future research needs on micro- and nanoplastic studies: From the detection to the toxicological assessment.
This critical review examines the current methods for detecting and characterizing micro- and nanoplastics in various environmental samples, as well as reported toxic effects from in vivo and in vitro studies. The authors found that while substantial effort has been made to understand microplastic behavior, the scientific community is still far from a complete understanding of how these particles behave in biological systems. The review calls for improved standardized protocols and more studies focused on uptake kinetics, accumulation, and biodistribution.
Accumulation, depuration, and potential effects of environmentally representative microplastics towards Daphnia magna
Researchers created environmentally realistic microplastics by grinding common consumer products and tested their effects on Daphnia magna, a small freshwater organism widely used in toxicity studies. The organisms accumulated the microplastics and showed some ability to clear them over time, but the realistic microplastics caused different effects than the pristine laboratory plastics typically used in research. This suggests that many existing studies may underestimate the true environmental risk of microplastics.
Microplastics in Aquatic Ecosystems: A Review of Ecotoxicological Effects, Exposure Pathways and Trophic Transfer Risks
This review synthesises evidence on the ecotoxicological effects of microplastics in marine, freshwater, and estuarine environments, covering ingestion, bioaccumulation, trophic transfer, and physiological harms across aquatic fauna.

Trophic transfer of microplastics in aquatic ecosystems: Identifying critical research needs
This review analyzed the available literature on trophic transfer of microplastics in aquatic food webs, identifying key factors — particle size, shape, density, and organism feeding behavior — that determine whether microplastics pass through organisms or accumulate. The authors conclude that biomagnification of microplastics remains poorly understood and requires targeted research.
