WebPM10 Particles. PM10 Particles are often called coarse particles. They range in size from 2.5 to 10 microns. These particles can irritate the eyes and throat. People with respiratory issues like COPD, Asthma and allergies can experience heightened symptoms when they are exposed to these sized particle. WebWe present the to date most detailed size distribution of SARS-CoV-2 RNA containing aerosol particles from the exhaled air that we collected from one person with COVID-19 on the day of symptom onset and the three following days. SARS-CoV-2 RNA was found in seven of the eight aerosol particle size fractions, from 0.34 to >8.1 µm ( Figure 2 (a) ).
