摘要:The main objective of this study was to assess the concentrations of some heavy metals of human health importance in the roadside dusts across three major locations in Monte Christo, Windhoek and compare the values with regulatory maximum permissible limits. Eighteen (18) samples of the roadside dusts (consisting of 6 each) were collected from both sides of the road at Hereford street, Fuel service station, and Traffic junction. The samples were digested using EPA method 3050B and analyzed for the heavy metals’ concentrations using Inductively Coupled Plasma-Optical Emission Spectrophotometer (ICP: Perkin Elmer Optima 7000 DV). The overall mean concentrations (mg/kg) of the heavy metals recorded across the sampling sites follow the order: Fe >Mn> Zn > Cu >Pb> Cr > Ni. Result of the analysis of variance between the mean concentrations of the heavy metals was statistically significant (Anova: single factor, p.
