Tobacco is one of the most important crops grown in the Republic of Macedonia. This crop can easily accumulate certain metals in its leaves. High concentration of these metals affects the quality of tobacco products and can have a harmful effect on consumers’ health. The soil study was conducted on family farms in different parts of Macedonia. Analyses were made on pH, humus, total content of Pb, Cd, Ni and Cr in soils, as well as concentrations of these elements in the three primings of tobacco. Correlation coefficients between the total metal concentration in investigated parameters in tobacco and soils indicated the existence of strong relationship between the lower, middle and upper primings for each metal. Statistically significant dependence was found between Pb contents of the plant material (all three primings) and humus, clay and Cd, Cu, Zn and Ni content in the soil. All other obtained results showed that the Pb, Cd, Ni and Cr contents in soil had no influence upon their accumulation in tobacco leaves. Metal concentrations in tobacco plants and respective soils were below the permissible limits.
