### Particulate matter (pm)

Measuring particulate matter involves quantifying the concentration of fine inhalable particles in the air, expressed as the count per cubic centimeter. This measurement is specific to the size of the particles with pm 1, pm 2.5, pm 4, and pm 10, representing diameters ranging from 0.3 to 1 um, 0.3 to 2.5 um, 0.3 to 4 um, and 0.3 to 10 um, respectively. Some common sources of PM10 include dust from roads, farms, dry riverbeds, construction sites, and mines.
