Abstract:
ncreases in tobacco smoking have been associated with health implications, because a
significant flux of heavy metals, among other toxins, reaches the lungs through smoking, hence
Ji:e need for research into the heavy metal content of cigarettes. In this study, the levels of trace
metals in tobacco cigarettes from samples of eight (8) cigarettes sold in Ethiopia were
determined. A wet digestion procedure involving a 0.5 g of oven dried cigarette sample was
digested using 5 mL of I lN03 and 2 ml. of H202 (30% wiv) at 200°C for 1 :30 h. Cadmium
(Cd), Lead (Pb), Zinc (Zn) and Copper (Cu) contents were determined in eight (8) brands or
cigarettes commonly avi~thle in Ethiopia by flame Atomic Absorption Spectroscopy (FAAS).
The concentration of trace metals in the cigarettes ranged: Cd, from 0.76 to 3.08 !Lg.ig, Pb, 2.12
to 7.13 ~1gig, Zn, 13.03 to 14.04 ~tg}g with, and Cu, 5.05 to 22.23 µgig. These elements were
present in all brands of cigarette and there is no significant difference among imported and
local htands of cigarette; except ill few cases of imported cigarettes which have higher Ievcl of
Cd. Zn anti Cu. As a result comparable results of trace metals are obtained in both imported
and F.thiopian
