ABSTRACT
The heavy metals Cd, Pb, Zn, Ni and Mo were determined in 27 samples of medicinal herbs taken from
various places in Bielsko Biała and the neighbouring area. Samples were digested by the wet method in
a microwave oven. Flame AAS and differential pulse polarography (anodic and stripping voltammetry) were
used for determination of these metals. Oriental tobacco (CTA-ATL-1) as the certified reference material
was applied for calibration and validation of analytical procedures.
