Mass measurements of particles in the atmosphere are important for regulatory and scientific purposes. In nearly all of the countries, particulates ≤ 10 µm in aerodynamic size (PM10) are one of the most significant parameters of National Ambient Air Quality Standards (NAAQS). In India, as given in NAAQS, the PM10 regulatory limit is 60 µg m−3 which is based on the annual mean weight of samples (minimum...
Nowadays particle size and mass concentration measurements are the important parameter of the ambient air quality standards of several countries. The regulatory limits of mass concentration of particulate matter (PM) for the size classes of PM2.5 and PM10, i.e., particle sizes of less than or equal to 2.5 and 10 μm in aerodynamic diameter, respectively in air are defined on yearly and hourly time-weighted-average...
