Abstract The content of Cd, Cr, Cu,

Abstract The content of Cd, Cr, Cu, Fe, Mn, Ni, Pb
and Zn was determined in commercially available black
and green tea from Sarajevo market. The concentrations
of metals in tea infusion and solutions prepared by
applying four digestion methods were determined by
using FAAS. The results show that the highest concen-
tration of total metals was obtained after acid digestion
in an autoclave. The concentration of metals soluble in
water obtained in tea infusion does not exceed maximum
allowed values provided by WHO (Guidelines for
drinking-water quality, World Health Organization,
Geneva, 2011). Among the investigated metals Mn was
the highest and ranged from 286 to 334 lgg-1
in tea
infusion of green and black tea, respectively, to 1,078
and 1,528 lgg-1
total content of Mn in green and black
tea, respectively. The concentration of heavy metals in
water extracts of tea was distinctly low in comparison
with the total content. The concentrations of Cd and Pb
were under the determination limit using FAAS. The
total content of all determined metals was higher in
black tea than in green tea.
