Investigations of economic importance of C, H, O and other micro (N, P, K, Ca, Mg, S) and
macro elements (B, Cl, Cu, Fe, Mn, Mo, Zn) revealed that the elements C, H and O constitute 90% of dry
matter and the other elements, which are easily movable, significantly affect the quality of tobacco leaves.
The contents of these elements and heavy metals vary in various parts of tobacco plant (leaf, root, stalk).
Leaves, stalks and roots of varieties P 12-2/1, P 112-2/1, P 146-3/2 and P 23 were dried at 750C and content
of the elements (K, Ca, Mg, Mn, Fe, Cu, Zn, Cd, Pb) was assessed on Atomic absorption spectrophotometer
(AAS Varian 220). The aim of this work was to study the content of biogenic elements and heavy metals in
some varieties of Prilep tobacco, especially in the leaf, with reference to their usability in cigarette
manufacture. It could be seen from the results that the contents of biogenic elements and heavy metals
differs, depending on the parts of the plant and on tobacco variety. The content of Cd ranges from 0.00005
mg/g in roots to 0.172 mg/g dry matter in leaves and the content of Pb from 0.05 mg/g in roots to 0.148 mg/g
dry matter in leaves.
