The fine dust fraction referred to as PM2.5 contains 50% of particles with a diameter of 2.5 µm, a higher proportion of smaller particles, and a lower proportion of larger particles. PM2.5 is a subset of PM10 - particles of this size can reach the alveoli in the lungs. They are maximally as large as bacteria and therefore cannot be seen with the naked eye.
