Particulate matter (PM) consists of airborne particles in solid or liquid form. The size of PM particles largely determines the extent of environmental and health damage caused. For this reason, PM is classified in different sizes: (1) Total Particulate Matter (TPM): Airborne particulate matter with an upper size limit of approximately 100 micro metre (µm) in aerodynamic equivalent diameter; (2) PM10: Particulate Matter <10 microns - airborne particulate matter with a mass median diameter less than ten µm; (3) PM2.5: Particulate Matter < 2.5 microns - airborne particulate matter with a mass median diameter less than 2.5 µm. Numerous studies have linked PM to aggravated cardiac and respiratory diseases such as asthma, bronchitis and emphysema and to various forms of heart disease. PM can also have adverse effects on vegetation and structures, and contributes to visibility deterioration and regional haze
