Isolation of microplastics in biota-rich seawater samples and marine organisms
Researchers developed and tested methods for extracting microplastics from seawater samples rich in biological material and from the tissues of marine organisms. They found that enzymatic digestion was the most effective and least destructive approach for isolating microplastics from biological samples, outperforming acid and alkaline treatments. The study provides improved laboratory protocols that will help scientists more accurately measure microplastic contamination in marine environments and wildlife.

A review on methods for extracting and quantifying microplastic in biological tissues
This review evaluates the methods scientists use to extract and identify microplastics from biological tissues like fish, shellfish, and animal organs. Researchers found that different extraction approaches (using acids, bases, or enzymes) yield different results, and many studies report finding plastics at sizes that may be too large to have actually crossed biological barriers. The study calls for more standardized and biologically plausible methods to improve the reliability of tissue contamination research.
Microplastic Extraction from Marine Vertebrate Digestive Tracts, Regurgitates and Scats: A Protocol for Researchers from All Experience Levels
This paper presents a standardized protocol for extracting and identifying microplastics from the digestive systems of marine vertebrates (mammals, birds, turtles, and fish). Having consistent, accessible methods is essential for generating comparable data on how much plastic wildlife across different species and regions are ingesting.
