Impact of Coastal Sediments of the Northern Dvina River on Microplastics Inputs to the White and Barents Seas

The Northern Dvina River flowing into the White Sea may be one of main sources microplastic (MP) pollution in Arctic region. coastal sediments act as an intermediate link transport microplastics to areas and Barents Seas. µFT-IR Py-GC/MS methods were used determine that up 200 particles or 120 mg MP per kg could accumulate River. Coastal tend ABS PS plastic with a particle size around µm. accumulated (218 117 sediment year) are carried away by strong currents, especially during spring flooding, resulting obtained data play important role assessing region,
