With the number of vehicles increasing, the analysis of highway roadside soils for contamination by heavy metals becomes expedient. This article deals with contamination by heavy metals of the roadsides of the Vilnius–Kaunas–Klaipėda (A1), Vilnius–Panevėžys (A2), Vilnius–Varėna–Grodno (A4), Vilnius–Utena (A14) and Vilnius–Prienai–Marijampolė (A16) highways. The analysis covers six heavy metals – nickel (Ni), copper (Cu), chromium (Cr), lead (Pb), zinc (Zn), and manganese (Mn), – the contaminants most often emitted by vehicles. The results have shown the maximum permissible concentrations (MPC) of the heavy metals in question to be not exceeded in any of the samples, but the concentrations of some heavy metals in the highway roadsides exceeded the background concentrations 1.3 to 6.7 times.
