PM = Particle Mass (μg/m³)(micrograms per cubic meter)

NC = Number Concentration (#/cm³)(count per cubic centimeter)

The World Health Organization recommends limiting particulate matter to the following values:

• Annual average PM10 20 µg/m³
• Annual average PM2.5 10 µg/m³ per year
• Daily average PM10 50 µg/m³ without permitted days on which exceeding is possible.
• Daily average PM2.5 25 µg/m³ without permitted days on which exceeding is possible
