“…Due to higher settling tendency of bigger particles of dust fallout fraction near emission sources on a regional scale, researchers have made classification of its reception pattern as ambient-outdoor, streetoutdoor and indoors dust fallout (Dubey and Pervez, 2008;Quraishi and Pandey, 1993;Sharma and Pervez, 2004;Gadkari and Pervez, 2007).…”

Abstract. The components and quantities of atmospheric dust fallout have been reported to be the pollution indicator of large urban areas. The multiplicity and complexity of sources of atmospheric dusts in urban regions has put forward the need of source apportionment of these sources indicating their contribution to specific environmental receptor. The study presented here is focused on investigation of source contribution estimates of Arsenic in urban dust fallout in an urban-industrial area, Raipur, India. Source-receptor based representative sampling plan using longitudinal study design has been adopted. Six sampling sites have been identified on the basis of land use for development plan of anthropogenic activities and factors related to the transportation and dispersion pattern of atmospheric dusts. Source apportionment has been done using Chemical Mass Balance (CMB 8). Good fit parameters and relative source contribution has been analyzed and documented. Dominance of coal fired industries sources on arsenic levels measured at selected ambient residential receptors compared to line sources has been observed. Road-traffic has shown highest contribution of dust at indoor houses and out door-street automobile exhaust has shows highest contribution for arsenic. The results of CMB output and regression data of source-receptor dust matrices have shown comparable pattern.

“…RPM (PM 5 )/PM 10 ratio has been evaluated to be in the range of 0.36-0.62 (Gadkari and Pervez, 2007). Plant workers have shown 1.5 to 2.5 times higher RPMHg levels compared to Category 2 and 20-30 times higher than Category 3.…”

“…Personal respirable fine particulates (RPM) have shown significant potential to major pathways of atmospheric pollutants in human exposure assessment around industrial areas (Gadkari and Pervez, 2007). The human exposure routes of mercury has been found as: inhalation, consumption of water, consumption of fish, beef, cow's milk, poultry, chicken eggs, pork, lamb, green plants and ingestion of soil (Warner et al, 2008;Kathryn, 2005 andRoser MartiCid, 2008).…”

“…In case of industrial combustion processes, stack emitted bag filter house dust samples were re-suspended tocollectPM 2.5 fractions using standard procedures reported elsewhere (Chow et al, 2004;Gadkari and Pervez, 2007). In case of open burning sources related to household fuel burning (RSFS, RKS, RLPGS), outdoor municipal waste burning practices (MSWB), arcwelding workshops (EAW) and brick kilns (BKP), PM 2.5 was sampled from smoke plume.…”

A study has been performed to develop PM 2.5 (particles with aerodynamic diameters ≤ 2.5) chemically speciated source profiles of different industrial and domestic burning practices in India. A total of fifty-five PM 2.5 samples have been collected in emissions resulting from (1) industrial furnaces, (2) household fuels, (3) municipal solid waste burning, and (4) welding workshop burning practices, and categorized for eleven subtypes of sources. The collected samples were subjected to chemical analysis for twenty-one elemental (Al, As, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Mg, Mn, Mo, Na, Ni, Pb, S, Sb, Se, V, Zn), nine ionic (Na + , K + , Mg 2+ , Ca 2+ , NH 4 + , Cl -, F -, NO 3 -, SO 4 2-), OC, and EC source indicator species using atomic absorption spectrometry, ion chromatography and carbon analysis (thermal/optical transmittance method), respectively. The carbonaceous fraction was most abundant in household fuel burning emissions (47.6 ± 7.45% to 65.92 ± 13.13%). The ionic/elemental ratios of major inorganic constituents (Ca 2+ /Ca, Mg 2+ /Mg and Na + /Na) have been identified to describe the PM 2.5 emissions from combustion or re-suspension dusts during industrial activities. Brick Kiln processes (BKP) have been identified as the major emitter of the highest number of toxic species (Cd, Co, Mo, Sb and V), followed by steel rerolling mills (Hg and Pb) and steel processing industries (As, Ni). The source marker calculations also confirmed that K + , Mn, and As are good markers for biomass burning, metallurgical industrial emission, and coal burning, respectively, similar to the findings in previous studies.
