The aim of this paper is to draw attention the direct source primary microplastics (MPs) that have been entirely neglected so far, namely by providing qualitative studies fishing ground baits with glitters. Among many microplastic sources already detected in and angling gear reported literature, glitters synthetic pastry are only (produced < 5 mm; P-MPs), MPs placed directly into freshwater, during sports competitions individual leisure activities, were far not discussed. Dozens different fishbait products available on market containing funded represent, from material point view, three classes studied further. Fourier-transform infrared (FTIR), ATR-FTIR Raman spectroscopy combined scanning electron microscopy an energy-dispersive detector (SEM/EDS) enabled characterization their composition morphology. Glitters composite structures internal core several chemical layers symmetrically both sides. polymer origin particles, polyethylene terephthalate (PET) core, was confirmed as being essential condition classify them P-MPs. One should focus fact those designed purposely be particularly attractive ingested fishes, thus efficiently introduced trophic chain all persistent consequences, including contribution plastisphere. preliminary results environmental stability obtained accelerated ageing test discuss possible long-term ecological implications durable saltwater (both natural used for weathering chamber) seabed sediments. performed marine environments, oceans final destination most freshwater MPs. Finally, suggestions future enlarge knowledge about issue provided.
