Every hour a person inhales 16 microplastic particles.

Physicists simulated the movement of microplastic particles through the upper respiratory tract of people. It turned out that every hour about 16 microparticles with a diameter of 1.6 to 5.5 microns settle in them. Plastic collects in the nasal cavities and oropharynx. Scientists believe that their model will help colleagues assess the impact of microplastics on the human body and develop methods for protecting people in polluted regions of the world.
