ABSTRACT: The road dusts (RD) are fugitive in nature causing potential health
hazards to people living in highways. They are generated from different sources
on the roads and being a valuable archive of environmental information. In the
present work, contamination assessment of 18 heavy metals and ions in road
dusts of the country are described. Techniques i.e. ion selective, ion chromatography and atomic absorption
spectrophotometers were used for analysis of the ions and metals. The content
of F-, Cl-, , , , Na+, K+, Mg2+, Ca2+,
As, Cr, Mn, Fe, Ni, Cu, Zn, Pb and Hg in the road dusts was ranged from 75 - 895, 276 -
12718, 48 - 1423, 243 - 10,580, 11 - 539, 290 - 46,484, 110 - 7716, 84 - 1771,
595 - 15,955, 24 -
42, 164 - 526, 1711 - 5218, 63,850 - 144,835, 47 - 62, 81 - 720, 166 - 450, 92 -
295 and 0.05 - 0.12 mg/kg with mean value of 224 ± 43, 3734 ± 895, 592
± 895, 2859 ± 662, 143 ± 29, 4826 ± 2049, 1565 ± 411, 837 ± 121, 8545 ± 1288,
31 ± 4, 246 ± 82, 3002 ± 851, 91,331 ± 18,587, 54 ± 4, 206 ± 145, 241 ± 64, 171
± 42 and 0.08 ± 0.02 mg/kg, respectively (at 95% probability). The enrichment,
variation, correlation and sources of the contaminants are discussed.
