Abstract

This study was focused on metal contamination of the road side dusty soil along with environmental impacts in the Dhaka City of Bangladesh. The energy based dispersive X-ray fluorescence (EDXRF) methods was applied to investigate the target metal (Pb, Cr, Zn and Cu) concentration form samples. Most of the metal content was observed to be higher compare to the background values. A significant positive correlation was found among the pairs of element Pb/Zn, Pb/Cr, Pb/Cu, Zn/Cr and Cr/Cu, respectively. Results showed that anthropogenic input and upward trends of industrial growth identified as a main cause of environmental contamination. Long term exposure of public health to metals may expedite health risk of the city dwellers.
