"Particulates, also known under the name of particulate matter (PM), are fine particles or soot. Particulate matter is frequently classified according to its size, i.e. PM10, PM2.5 and PM0.1 for particulates with an aerodynamic diameter D smaller than, respectively, 10 µm, 2.5 µm and 0.1 µm. PM represent an hazard for human health. Very coarse particles (D > 10 µm) are generally filtered in the no ...
