During 2019, within the JDS4 expedition, for the first time, research was conducted that included the detection, quantification and categorization of microplastic particles present in the biota of freshwater ecosystems. The research was conducted along 2040 km of the Danube and larger tributaries, from Germany to the Black Sea. The allochthonous species Corbicula fluminea (Muller, 1774) was used as a model organism for the analysis of microplastic particles. A total of 216 individuals from 23 localities were collected. The collected particles were photographed, measured, counted and classified into one of the 5 main categories of microplastics: fibers, hard plastics, nylon, rubber or other, ranging in size from 0.02 to 4.67 mm. A total of 1998 microplastic particles were collected with an average of 9.25 particles per organism or 26.4 particles of g-1 wet shell body weight. Based on microFTIR spectroscopy analysis, the particles were characterized as polycarbonate, polyethylene terephthalate (PET), polypropylene-polyethylene copolymer, nylon (polyamide-PA) and cellophane, with a predominance of PET, which is used to produce plastic bottles. The study of JDS4 microplastics in biota provided the first information on plastic particles present in biota, which indicates an plastic pollution along the Danube River.
