Abstract: The concentration of Pb and Cd is searched to 60 plants of Medicago sativa L. along Lipjan-Prizren highway in different distances from the road. While searching, it is used the plant growth on the ground. Based from the searching results, it is noticed that the concentration of Pb and Cd on three searched places has been higher in the locations near the road, except point three which the quantity of Cd has been higher in distance of 10 m far from the road. On all tested plants the highest biomass has been found to the plants which are located in distance of 10 m far from the road. On all three searched points, there are noticed negative correlations among the concentration of Pb, Cd and biomass.
