ClearNondestructive Extraction and Identification of Microplastics from Freshwater Sport Fish Stomachs
Researchers developed a nondestructive protocol for extracting and identifying microplastics from freshwater sport fish stomachs containing large amounts of biological material, enabling more accurate counts without damaging the plastics. This method improvement helps ensure that ingested microplastics in fish are not missed or damaged during laboratory processing.
Protocol for extraction and analysis of microplastics in freshwater, sediment, and fish samples
Researchers developed a standardized protocol for extracting and identifying microplastics from freshwater, sediment, and fish digestive system samples, combining chemical digestion, density separation, vacuum filtration, and Raman spectroscopy to enable reliable, reproducible analysis across aquatic sample types.

Methods of digestion, isolation and identification of microplastics present in the fish gut content
This study evaluated four digestion methods for isolating microplastics from fish gut contents, finding that a combination of nitric acid and hydrofluoric acid was most effective while preserving particle structure. Microplastic particles were found in the digestive tracts of all analyzed fish from Croatian freshwater and marine ecosystems, highlighting the widespread contamination of aquatic food sources.
Improved methodology for microplastic extraction from gastrointestinal tracts of fat fish species
Researchers improved microplastic extraction from fatty fish tissues by adding a small amount of the surfactant Tween-20 to potassium hydroxide digestion protocols, which disrupts the soap layer that forms during fat digestion and significantly increases microplastic recovery rates.
Food preference determines the best suitable digestion protocol for analysing microplastic ingestion by fish
Different fish species with different diets require different chemical digestion methods for accurately extracting and identifying microplastics from their digestive tracts. Choosing the right protocol for each species is essential for avoiding underestimation of microplastic ingestion, which affects the accuracy of food safety assessments.

A new one-step laboratory method was developed to efficiently digest and extract microplastics from mussel and fish tissue samples. Standardized extraction methods are critical for making microplastic studies comparable across different labs and species.
Feasibility Study on Biomonitoring of Microplastics in Fish Gastrointestinal Tracts
This feasibility study assessed using fish gastrointestinal tracts as biomonitors for environmental microplastic contamination, evaluating sampling protocols, species selection, and analytical methods to establish standardized biomonitoring frameworks for marine plastic pollution.
Hyperspectral Imaging Based Method for Rapid Detection of Microplastics in the Intestinal Tracts of Fish
Researchers developed a hyperspectral imaging-based method to directly detect and identify microplastics in fish intestinal tracts without requiring tissue digestion or particle extraction, enabling faster and less reagent-intensive analysis compared to conventional Raman or FTIR approaches.
Effective and easy to use extraction method shows low numbers of microplastics in offshore planktivorous fish from the northern Baltic Sea
Microplastics were found at low levels in planktivorous fish from the northern Baltic Sea using a validated alkaline digestion extraction method. The study demonstrates an efficient, validated protocol for detecting microplastics in fish and provides baseline contamination data for Baltic marine food webs.
A new digestion approach for the extraction of microplastics from gastrointestinal tracts (GITs) of the common dolphinfish (Coryphaena hippurus) from the western Mediterranean Sea
Researchers developed a novel combined KOH and nitric acid digestion protocol for extracting microplastics from the gastrointestinal tracts of marine fish, and validated it on common dolphinfish from the western Mediterranean Sea. The method improved detection of small MPs, with 65.5% of dolphinfish containing meso- and microplastic fragments and sheets predominantly composed of polyethylene, polypropylene, and polystyrene.

Researchers developed a faster method for extracting microplastics from fish tissues using a combination of detergents and potassium hydroxide, completing digestion of 100-gram samples within 16 to 24 hours — far quicker than existing multi-day protocols. The technique reliably recovered six common plastic types down to 60-80 micrometers in fatty fish like mackerel and salmon, making routine food safety monitoring more practical.
