In this study, heavy
metals such as Zn, Cr, Cd, Pb, Ni, Fe and Cu were investigated in Verbascum
insulare Boiss. & Heldr. (Scrophulariaceae) as well as in soil grown by
using ICP-OES. The aim of this study was
to examine the potential of biomonitors for heavy metal polluted areas. The
plant and soil samples were collected from their natural habitat at different
locations in 2017. In the whole plant, Cr among all heavy metals was found to
be at the highest level of 140,55 mg/kg, followed by Pb 63,70 mg/kg and Fe
57,30 mg/kg, while the other metals were at low concentration in V. insulare
Boiss. & Heldr. The obtained data were compared with the respective values
recommended by the polish standards. Our findings were tested with one-way
ANOVA Duncan tests for high significance levels of P<0.01. We found the
plants to be reliable biomonitors for remediation methods. The present study
showed that heavy metals such as Zn, Cr, Cd, Pb, Ni, Fe and Cu were found in
the three locations, and the overall levels of metals were in the order of
Aşkale (L3) > Çat (L2) > Palandöken Mountain (L1). V. insulare might be
suitable for remediation of Cr-, Pb- and Fe-contaminated soils. This plant can
be used as a bioindicator and a biomonitor for polluted heavy metals.
