of the analysis of As, Sb, and Tl in different plant parts (roots, stems, leaves, and
flowers) of Thymus endemic species that grow in the Allchar mining area, BAF and
BTF were calculated (Table 13.10).
For As and Sb in this endemic species, BAF was insignificant. For Tl, BAF was
7.5, which was significantly higher. BTF for Tl in samples of Thymus was 0.89,
which was smaller than the BAF. Data in Table 13.10 show that BAF for the Tl was
significantly higher than that for As, showing that T. alsarensis was capable to accumulate high amounts of Tl than As and Sb.
The calculated values for BAF and BTF for the contents of As, Sb, and Tl in various parts of the plant (root, stem, and leaf) of Centaurea leucomalla are presented in
Table 13.11. It was obvious that the BAF values for As and Sb were insignificant,
while this factor for Tl was the highest (BAF = 0.46). This indicates that the endemic
Centaurea leucomalla from Allchar accumulates thallium much more intensively than
