Transport Pollution in India

Abstract

Road dusts contribute a large fraction of air pollution in urban environment of India. In the present work, contamination assessment of ions and elements i.e. F−, Cl−, , , , Na+, K+, Mg2+, Ca2+, As, Cr, Mn, Fe, Ni, Cu, Zn, Pb and Hg in the road dusts of the most industrialized area of central India: Raipur (capital, Chhattisgarh state) is described during year: 2008-2013. In year 2008, the mean content of the element i.e. F−, Cl−, , , , Na+, K+, Mg2+, Ca2+, As, Cr, Mn, Fe, Ni, Cu, Zn, Pb and Hgin the dust (n = 5) was found to be 292 ± 112, 5068 ± 2445, 927 ± 280, 3336 ± 1315, 155 ± 65, 4273 ± 1761, 1477 ± 626, 974 ± 243, 9809 ± 2370, 21.2 ± 2.4, 150 ± 30, 12,816 ± 12,522, 157,736 ± 61,542, 60 ± 7, 566 ± 608, 348 ± 154, 296 ± 163 and 0.10 ± 0.09 mg/kg, respectively. The enrichment, concentration variations and sources of the elements are discussed.
