Вестник Томского государственного университета. Биология № 52. С. 130-139Abstract: This preliminary study investigated the abundance of microplastic particles in gastrointestinal tracts of the dace (Leuciscus leuciscus L.) from the Tom River, a large tributary of the Ob River in West Siberia. A total of 13 dace specimens of 2+ to 4+ years of age were studied. Microplastic particles extracted from fish guts were counted and classified by shapes and sizes. In average 204 ± 28.7 items of microplastics were detected for one dace specimen. Microplastic particles were categorized as fragments of irregular shape (70%), spheres (16%), films (7%) and fibers (7%), with size ranging from <0.15 to 2.00 mm. The vast majority of detected microplastic particles (almost 80%) were less than 0.15 mm by their largest dimension. These data provide the first evidence of microplastics in fish from the Ob River system.
