This study was conducted to determine the heavy metals of Cd, Mn, Ni, Zn, Pb, Cu, and Cr in two naturally grown plants
(Hippophae rhamnoides L. and Pyrus elaeagnifolia Pall.) and on the roadside soil. The samples in this study were collected
from the European route e80 highway in Türkiye. Average concentrations of metals in surface soil samples were: Cd, 0.47;
Mn, 656.18; Ni, 96.68; Zn, 171.90; Pb, 33.42; Cu, 45.82; and Cr, 95.60 ppm. Pollution levels were estimated based on soil
pollution index (PI) and geoaccumulation index (Igeo). The general trends of soil pollution index (PI) and geoaccumulation
index (Igeo) were Cu>Pb>Cd>Cr>Ni>Mn>Zn. Additionally, transfer factors (TF) were calculated to evaluate the feasibility of plant species for phytoremediation purposes. The leaf part of H. rhamnoides (Seabuckthorn) has the highest TF
for Cu among plant parts. Finally, in this study, the highest transfer factors were determined as Cu and Zn in Seabuckthorn;
P. elaeagnifolia (Wild Pear) these are heavy metals Cu and Cd. In particular, it is thought that employing plant leaves as a
monitoring technique may be helpful in keeping track of changes in Cu, Cd, and Zn concentrations in situations along highways. In particular, it is thought that employing plant leaves as a monitoring technique may be helpful in keeping track of
changes in Cu, Cd, and Zn concentrations in situations along highways. The fndings of this study can be further interpreted
to assess the risks that may arise from exposure to heavy metals at the edge of highways.
