TSU scientists discover the source of microplastic in snow and rain


TSU scientists were among the first in Russia to study the atmospheric transport of microplastic. Samples of rain and snow collected in Siberia demonstrated that the prevalent type of microplastic is synthetic fiber. It is the lightest kind and so gets transported more easily.

Microplastic transport studies is a global trend that began abroad just a couple of years ago. TSU Biological Institute scientists were the first in the Russian Federation to conduct regular studies. They have analyzed the speed and scale of atmospheric deposition of microplastic in different places of Siberia, including the Tomsk city perimeter. From November 2020 until May 2021, scientists collected all the deposition that fell in a specific spot for a month. After that, the scientists extracted microplastic from samples and counted and classified it.
