ClearMicroplastic in freshwater ecosystem: bioaccumulation, trophic transfer, and biomagnification
This review synthesizes evidence on microplastic bioaccumulation and trophic transfer in freshwater ecosystems, finding that while ingestion by freshwater organisms is well-documented, biomagnification through food chains remains poorly understood and requires further investigation.
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.
Worldwide contamination of fish with microplastics: A brief global overview
A literature review from March 2019 to March 2020 synthesized worldwide data on microplastic contamination in fish, finding that a median of 60% of fish from 198 species across 24 countries contained microplastics in their organs. Carnivorous species ingested more microplastics than herbivores, consistent with trophic transfer and bioaccumulation through food webs.
Microplastic in tissue of marine organisms
This review summarizes microplastic detection across various marine organism tissues, cataloging accumulation in fish, invertebrates, and marine mammals and highlighting that ingestion and trophic transfer are widespread across marine food webs.
Microplastics in aquatic organisms: Improving understanding and identifying research directions for the next decade
This meta-analysis reviews a decade of research on microplastic ingestion by aquatic organisms, from tiny plankton to large fish. It identifies major knowledge gaps, including the long-term health effects of ingestion and what happens as microplastics move up the food chain toward human consumers.
Global distribution characteristics and ecological risk assessment of microplastics in aquatic organisms based on meta-analysis
This meta-analysis assessed the global distribution of microplastics in aquatic organisms across multiple trophic levels, finding that biological characteristics like body size and feeding strategy significantly influence microplastic ingestion rates. The study provides a framework for ecological risk assessment and proposes strategies to reduce microplastic input into water bodies.
Occurrence and characterization of microplastic content in the digestive system of riverine fishes
Researchers found microplastics in 93.8% of riverine fish examined, with polystyrene, polyethylene, and nylon being the most common polymer types concentrated near urban and industrial areas, and small particles (0.025-1 mm) predominating across species.
Quality Criteria for the Analysis of Microplastic in Biota Samples: A Critical Review
Ten quality criteria were applied to review recent microplastic ingestion studies in aquatic biota, finding wide variation in methodological rigor including inadequate sample sizes, poor contamination controls, and inconsistent polymer identification methods. The authors propose a standardized quality assessment framework to improve comparability of microplastic ingestion data across studies.
Microplasts in Freshwater Fish – Problems and Challenges
This review examines microplastic contamination of freshwater fish, covering ingestion evidence from over 150 species, the mechanisms of accumulation in gastrointestinal and other tissues, potential health impacts, and challenges in standardizing quantification methodologies.
Addressing the current fettle of bioaccumulation of microplastics on the subsequent perspective of the aquatic ecosystem and health implications of commercial species: a review
This review examined the global evidence for microplastic bioaccumulation in aquatic animals and the downstream risks to ecosystem health and food security. The authors highlight how ingestion of plastic-contaminated prey transfers microplastics up the food chain.
Do Larger Microplastics Biomagnify in the Digestive Tracts of Coastal Marine Animals?
Researchers collected coastal marine animals across multiple trophic levels using beach seining, snorkeling, and SCUBA diving, then used stable isotope analysis to examine whether larger microplastics biomagnify in digestive tracts with increasing trophic position, finding limited evidence for systematic biomagnification of larger particles.
Microplastics in aquatic food chain : sources, measurement, occurrence and potential health risks
This review examines the sources, measurement methods, occurrence, and potential health risks of microplastics throughout aquatic food chains, finding that while microplastics are ubiquitous in fish, shellfish, and other aquatic food sources, the data needed for a comprehensive human dietary exposure and risk assessment are not yet available. Researchers identify standardization of detection methods as a critical prerequisite for meaningful risk evaluation.
Comprehensive systematic review and meta-analysis of microplastic prevalence and abundance in freshwater fish species: the effect of fish species habitat, feeding behavior, and Fulton’s condition factor
A meta-analysis of freshwater fish across 42 studies found an average of 2.35 microplastic items per individual, with 80% of research focused on the gastrointestinal tract and 58% on river environments. Contrary to expectations, microplastic ingestion correlated with fish body physiology (size and weight) rather than feeding behavior or habitat, suggesting physical characteristics determine uptake more than ecological niche.
The Challenge of Microplastics in Aquatic Ecosystem: A Review of Current Consensus and Future Trends of the Effect on the Fish
This review synthesizes research on how microplastics affect aquatic ecosystems, covering ingestion by marine animals, trophic transfer up the food chain, and the chemicals that microplastics carry. The findings highlight that microplastic contamination is now widespread enough to threaten marine biodiversity and food security for populations that rely on seafood.
A central role for fecal matter in the transport of microplastics: An updated analysis of new findings and persisting questions
This review examines the central role of fecal matter in transporting microplastics through ecosystems, analyzing how organisms ingest and excrete microplastics and the implications for environmental fate and human exposure monitoring.
Microplastic profusion in food and drinking water: are microplastics becoming a macroproblem?
This review examined the prevalence of microplastics in food and drinking water, assessing trophic transfer along the food web and evaluating whether microplastic contamination in human dietary sources constitutes a growing public health concern.
Micro-Nano Plastics in Aquatic Environments: Associated Health Impacts and Mitigation Strategies
This review examines how micro- and nanoplastics in aquatic environments are biologically transferred up the food chain, covering the factors that influence particle bioavailability, accumulation in organisms, and trophic transfer — with implications for both aquatic ecosystem health and human dietary exposure.
What are the global patterns of microplastic ingestion by fish? A scientometric review
This review summarizes global research on microplastic ingestion by fish and finds that contamination is widespread across aquatic ecosystems, with fibers and fragments being the most commonly ingested shapes. The study highlights that fish higher on the food chain tend to accumulate more microplastics, which matters for human health since many of these species are commonly consumed as seafood.
Microplastic: A Silent Contaminant in Aquatic Ecosystems and Its Ecological Consequences
This review examines microplastics as a pervasive but underappreciated contaminant in aquatic ecosystems, synthesizing evidence on their sources, distribution, uptake pathways in aquatic organisms, and broader ecological consequences for freshwater and marine food webs.
Micro(nano)plastics in the fish gastrointestinal tract: A mini review and relevance to One Health perspective
Researchers reviewed how microplastics and nanoplastics accumulate in fish digestive systems and enter the broader food web, highlighting that the fish gut acts as a critical pathway for these particles — and the chemicals stuck to them — to travel from the environment into the human food supply.
