Research of the Microplastic Content in the Floodplain Alluvium of the Upper Volga
Summary
Researchers examined microplastic accumulation in floodplain alluvium of the upper Volga River near the city of Tver, collecting soil samples from within the city and both upstream and downstream using a modified NOAA extraction protocol. Microplastic particles were detected in all samples, with films, granules, and fragments in the 1-2.5 mm size range predominating, and higher concentrations found within the urban area.
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.

Research of the Microplastic Content in the Floodplain Alluvium of the Upper Volga
Researchers collected and analyzed soil samples from floodplain alluvium along the Upper Volga River near Tver, Russia, using a modified NOAA protocol to detect and characterize microplastic accumulation. Microplastic particles were found in all samples, with the highest concentrations near plastic production and processing enterprises, and films, granules, and fragments in the 1-2.5mm size range predominating.
Microplastic Abundance In Volga River: Results Of A Pilot Study In Summer 2020
Researchers conducted the first comprehensive survey of microplastic pollution along the entire Volga River in summer 2020, finding an average concentration of 0.90 items/m3 with microplastics present in all 34 samples and maximum concentrations near urban centers.
Microplastic in soils: Method development and application to Swiss floodplain soils
This Swiss study developed methods for extracting and analyzing microplastics from floodplain soils, finding plastic particles in all samples taken from Swiss riverine environments. The research is among the first to demonstrate widespread microplastic contamination in terrestrial floodplain soils in Europe.
Microplastic Concentrations in Some Rivers and Reservoirs in Southern Russia
Researchers assessed microplastic concentrations in major rivers and reservoirs of southern Russia — including the Lower Don, Lower Volga, Seversky Donets, and Tsimlyansk Reservoir — using multiple sampling methods across several years. Concentrations ranged from 12.3 to 94.32 particles/m3 in more recent surveys, with the highest accumulation observed in anthropogenically impacted areas, tributaries, and near hydraulic structures, and transparent polyethylene and PET fibers being the most common particle type.
Deposition and in-situ translocation of microplastics in floodplain soils
A study of microplastic deposition and in-situ vertical translocation in floodplain soils found that flooding events deposit microplastics from river water onto floodplain surfaces, and that subsequent rainfall and bioturbation can move particles downward through the soil profile.
