The content of copper, lead, cadmium, zinc, manganese and iron was determined in our investigations of tobacco grown in the region of Prilep. Tobacco samples were burned according to the method of wet burning with nitric and perchloric acid and measurements were made on atomic absorption spectrometer VARIAN SPECTRA AAA. The content of investigated elements in tobacco ranged as follows: Cu 2.413 - 47.806 mg/kg; Pb 2.5 -14.13 mg/kg, Cd 0.007 - 1.37 mg/kg; Zn 14.253 - 63.482 mg/kg, Mn 31.21-571.15 mg/kg; Fe 318.72 - 2532.01 mg/kg.Based on the investigations, it can be stated that heavy metals content in tobacco raw produced in the region of Prilep, with small exceptions, is ranging in referent limits for this crop. According to the results obtained, tobacco grown in this region is ecologically pure and safe both for domestic consumption and for exports.
