Concentrations of heavy metals in the soil such as: (Pb, Cd, Zn and Cr), play a role in contamination of agricultural crops such as: wheat cultivation (Triticum aestivum L.). Roads in the Republic of Kosovo are congested with traffic, which over 55% are obsolete over 20 years. Agricultural land near roads in Kosovo is land where agricultural products are cultivated, especially wheat. This study aims to investigate the concentration of toxic metals in soil and wheat crops due to vehicle emissions. In this research are examined the physico-chemical factors that affect the mobility of metals in the soil of the research area as; pH, concentration of organic carbon and heavy metals such as: (Pb, Cd, Zn and Cr). Analytical research shows that the content of toxic metals decreases with increasing distance or distance along highways. Concentration of toxic metals near roads, lands planted with analyzed agricultural crop of corn, tests show that heavy metal deposits also depend on atmospheric conditions and emissions from vehicle traffic. When planning wheat harvest for food safety along highways, the concentration of heavy metals are some very high cases in relation to the distance (road / crop), agricultural.
