Particulate matter (PM)

Particulate Matter (PM) is a complex mixture of extremely small solids and liquid droplets. “It may include components such as acids (such as nitrates and sulfates), organic chemicals, metals, and soil or dust particles.” Their properties are often categorized according to their aerodynamic diameter in micrometers.

• Total Suspended Particulate Matter (TSP) Particles with aerodynamic diameters 20-50 micrometers in diameter
• Coarse Particles (PM10) Particles with aerodynamic...
