Abstract
The accumulation of heavy metals in soil at roadside has been studied by the analysis of top soil/dust samples. Concentration of the elements Co, Cr, Pb and Cd were measured on 39 top soil/dust samples collected from near the highways, industrial area and control site. The samples were analysed for Zn, Cu, Fe, Mn, Pb, Cd, Ni, and Cr by using atomic absorption spectrophotometer (AAS). The mean concentrations of Co, Cr, Pb and Cd were 0.390, 0.090, 2.195 and 0.094 mg kg-1, respectively. Data obtained from analysis, were statistically examined to know the distribution of metals in different highways and industrial area. The results showed that the topsoil/dust near the highway and industrial sites had significantly enrichment particularly Pb than control sites.
