ClearQuality 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.
Occurrence, Distribution, and Extraction Methods of Microplastics in Marine Organisms
This review synthesizes global data on microplastic occurrence and distribution across marine organisms, comparing the advantages and limitations of different extraction and identification methods used in the field.
A critical view on microplastic quantification in aquatic organisms
Researchers critically reviewed the methods used to quantify microplastics in aquatic organisms including zooplankton, bivalves, and fish. The study highlights that no standardized methodology exists for measuring microplastic contamination in biota, which makes comparing results across studies difficult and underscores the need for consistent analytical protocols.

Marine mammals and microplastics: A systematic review and call for standardisation
Microplastics were found in the gastrointestinal tracts of marine mammals in all but one of 30 studies reviewed, with 0-88 particles per animal, and were detected in pinniped scat in 8 of 10 studies, though considerable methodological inconsistencies make cross-study comparisons difficult.
Sampling, Isolating and Identifying Microplastics Ingested by Fish and Invertebrates *
This methodological review critically evaluated sampling, isolation, and identification techniques for microplastics ingested by fish and invertebrates, identifying common sources of error including contamination during processing, particle loss, and misidentification — and recommending standardized protocols.

Quantifying ingested debris in marine megafauna: a review and recommendations for standardization
This review examined published methods for quantifying ingested plastic debris in marine megafauna — including whales, turtles, and sharks — and found wide variation in reporting practices. The authors propose standardized protocols for sample collection, processing, and data reporting to enable meaningful comparisons across species and regions.
Recovering microplastics from marine samples: A review of current practices
This review compared the published methods for separating and identifying microplastics from seawater, sediment, and marine organisms, assessing their efficiency, processing time, and potential to damage particles. It highlights the lack of standardized protocols as a major barrier to comparing results across studies.

Microplastics Monitoring in Marine Environment
This review summarises the need for standardised methods for microplastic sampling and analysis across seawater, beach sediment, seabed sediment, and marine organisms to enable consistent spatiotemporal comparisons of microplastic abundance in marine environments.
Microplastics’ Impact on the Environment and the Challenging Selection of Reliable Key Biomonitors
This review examines the challenges of using living organisms as reliable monitors for microplastic pollution in the environment. Different species accumulate microplastics at different rates depending on their habitat, feeding habits, and body size, making it hard to compare results across studies. Establishing standardized biomonitors is important for accurately tracking how much microplastic contamination is reaching wildlife and, ultimately, the human food supply.
Plastics in biota: technological readiness level of current methodologies
Researchers evaluated the scientific readiness of current laboratory methods for detecting and measuring plastic particles inside living organisms — from fish to insects — identifying which techniques are reproducible enough to be used in standardized environmental monitoring programs. Harmonizing these methods is critical for generating consistent, comparable data on how plastics accumulate across food webs.
