Abstract
In this study, the heavy metal pollution caused by vehicle traffic was investigated in the leaves of Verbascum sinuatum L.(Scrophulariaceae) collected from the Blacksea coast ranging between Samsun, Ordu, Giresun, Trabzon, Rize and Hopa. Sample collection procedure was made in 23 stations in the related route. Heavy metal concentrations in the leaf samples of each station were determined with Perkin Emler Optic Emission Spectrometry (ICP-OES). Heavy metal concentration in samples was showed an order as Lead (Pb) > Zinc (Zn) > Chromium (Cr) > Nickel (Ni) > Copper (Cu) > Cadmium (Cd). The results of this study showed that the heavy metal accumulation in samples increased with an increase in traffic and V. sinuatum used as a biological indicator of this accumulation.
