13.3.4 Onobrychis degenii Dörfler and Knautia
caroli- rechingeri Micev.
After statistical process of the analyzed results for plant specimens of the endemic
plant species Onobrychis degenii Dörfler and Knautia caroli-rechingeri Micev. and
the corresponding soil samples, the data of the 27 analyzed elements from different
parts of the plant (root, stem, leaf, and flower) are obtained (Bačeva et al. 2018b). In
Table 13.8 data for the content of As, Sb, and Tl are presented. Plant species
Onobrychis degenii and Knautia caroli-rechingeri were taken in the Crven Dol area
or a hydrothermal-modified rock area, where the mineralization of As and Tl was
predominant.
The content of As in the root of O. degenii was 114 mg kg
−1
and for K. carolirechingeri was 354 mg kg
−1
. The content of As in the aboveground parts of the plant
O. degenii was 4.03 mg kg
−1
in the leaf and 3.49 mg kg
−1
in the flower. For K. carolirechingeri, the content of As in the leaf was 3.78 mg kg
−1
(Table 13.8). The content
of Tl in the root of these plants was also high, ranging from 86.7 mg kg
−1
in the roots
of O. degenii to 216 mg kg
−1
in the roots of K. caroli-rechingeri (Table 13.8). For
the other parts of the plants (stem, leaf, and flower), the content of Tl in O. degenii
was 6.3 mg kg
−1
, 6.8 mg kg
−1
, and 6.19 mg kg
−1
, respectively, while for the K. carolirechingeri the content of Tl in the stem, leaf, and flower was higher: 26.3 mg kg
−1
and 10.4 mg kg
−1
, respectively (Table 13.8). The content of Sb was significantly
lower in different parts of the plants compared to the content of As and Tl
(Table 13.8). The reason for this is due to the low content of Sb in the part of Crven
