Particulate Matter (PM) Concentration

The particulate matter (PM) concentration in the air is calculated by dividing the mass of the particulates by the volume of air. In this formula, PM represents the concentration of particulate matter, mass is the total mass of the particulate matter in micrograms (µg), and volume is the volume of air through which the particulate matter is dispersed, in cubic meters (m³). This computation is critical in environmental science, air quality studies, and health assessments where PM concentrations impact respiratory health.
