Abstract

Heavy metal concentrations play an important role in affecting the health of people by an overall activation of the haemostatic system upon chronic/acute exposure of these contaminants present in air. Present study was conducted with an objective to estimate metal concentration in the street dust of Delhi. 14 different sites were selected for the study which included industrial, commercial, bus terminals and other areas. Inductively Coupled Plasma-Optical Emission Spectrometer analysis showed that Al had the highest concentration while Cd had the lowest. Pb concentration was recorded to be high in the present study sites, but relatively low as compared to those cited in previous literatures due to an early phase-out of leaded gasoline.  Industrial areas reported high concentrations of Cr & Fe, Cu &Zn, and Al &Ca. Besides anthropogenic activities, natural sources do account for heavy pollution of metals in the street dusts of Delhi (Ca and Fe), which are present in its loosely bound soil. Anthropogenic sources are major contributors to the trace metal pollution in Delhi. Residential-cum-commercial area had lowest concentration for all the metals studied. Correlation coefficient analysis indicated that industrial activities are the source of Cd, Ni & Cu, and Pb, Mn, Zn and V. Fe, Mn, Ni, V, Al are a result of dust re-suspension from traffic related sources.
