Air is a very essential part for the existence of humans and other living organisms. To know the quantum of atmospheric dust fall and theirmineral andmorphological characteristics, dust sampleswere collected at monthly intervals from three different sites (commercial, residential, and control) of the Jharia coal mining area, India. Sampleswere analysed for heavymetals, minerals, andmorphological features by ICP-AES, XRD, and SEMrespectively. The yearly average dust fall was higher for the commercial site (15.5 t/km2/month) than the residential site (10.7 t/km2/month) of Jharia coal mining area. The dust deposition rate was highest during summer (March–June), followed by winter (October–February) and lowest in the monsoon season (July–September). The elemental fall was higher for Zn followed by Pb N Sr N Cu N V N Cr N Ni N Co. The major minerals in dusts from Jharia mining area were quartz, kaolinite, pyrite, albite, and magnesiohornblende. The SEM-EDS analysis showed the dust in commercial sites has contributions from coal, and soil. In the residential site, soot particles fromdomestic coal burning; and in control site, soot particles frombiomass burningwere observed in SEM. Overall the intensity of dust pollution is more in the commercial sites of the coal mining area.
