Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
Summary
This study compared microplastic contamination across commercially relevant seafood species commonly consumed in the European market, characterizing both the morphological and chemical properties of particles found in edible tissue. Results showed widespread but variable contamination across species, with polymer types and particle abundance differing by species and tissue type.
The pollution of the environment with plastics and derived secondary parts, microplastic, is a growing concern worldwidefor animal, human and environmental health. Analysis of occurrence and characterization of the morphological and chemical characteristics of microplastics (MP) in commercially relevant species and their edible parts (flesh or muscle) are prerequisites for food risk assessment. Despite accumulated evidence of MP contamination in different food products, it is very challenging to compare data on the same species from different studies due to the lack of standardized methods. Hence, the aim of our study was to compare MP contamination of edible parts of commercial mussels, clams and shrimps samples collected from geographically distinct markets (South Korea, Belgium, Serbia, and Croatia), thus minimizing methodological variations. Samples (individual animal) have been subjected to an alkaline/enzymatic/oxidative digestion yielding ≥ 99.8 Also see: https://micro2024.sciencesconf.org/558446/document
