Abstract

The results of a study of the accumulation of microplastics in the caught alluvium of the river. Volga near the city of Tver. There were significant soil samples within the city, upstream and downstream of the river. Sample processing was carried out according to the modified method of the US Atmospheric and Oceanic Administration (NOAA). Microplastic particles are found in all samples, limiting the number of coverages in the inclusion area for the production and increase in the amount of plastic. It was found that films, granules and fragments of plastic particles ranging in size from 1 to 2.5 mm along the largest axis predominate in all selected samples.
