Multielement Contamination of Land in the Margin of Highways

The spatial distribution of potentially toxic elements in land near a heavily loaded highway the West Attica region (Greece) is discussed. This study aimed to investigate extent soil contamination with trace on margin highways. concentration thirty-five topsoil, car ash, and road sediment bulk samples was determined. Statistical analysis applied for evaluating geochemical dispersion examined elements. Geo-accumulation index estimated. Elements content were compared criteria screening values established by literature. As, Cu, Mn, Ni, P, Pb, Zn topsoil appeared be influenced traffic emissions. It found that engine exhaust, tyre wear, brake lining contribute Ba, recorded sample moderately contaminated extremely Zn. Comparison revealed Al, B, Cd, Co, Cr, Fe, Sb, V, pose potential risk plants.
