Abstract :A study was carried out to identify Cd, Pb and Zn concentrations which exist in the roots and stems of Astragalus pycnocephalus Fischer and Verbascum euphraticum L. plants which grow in the Görgü Pb-Zn mining area. A total of 60 samples were collected, 30 samples from plants and 30 samples from the soils where the plants grow. When the anaytical results gained are statistically examined, according to correlation coeffi cients graphic between the soil and plant, fi nding positive correlation between (A. Pycnocephalus) soil-root (Cd, r =0.77), soil-stem (Cd, r =0.86) and soil-stem (Pb, r =0.77) could mean that these could be indicator plants and can be used for remediation of the soils polluted by Cd and Pb metals. It is observed that the metallic concentration times values of the plants in this study taken from polluted areas compared to the plants taken from unpolluted areas, are quite high in total 44 samples. Transition factor is >1 in some sample locations and range between 0.13 and 2.07. Enrichment coeffi cients is>1 for the location of V11 (Cd, root/soil). A. Pycnocephalus and V. Euphraticum, in some locations, according to transition factor, enrichment coeffi cients, times values and element concentrations could be identifi ed as accumulator/hyperaccumulator for Cd, Pb and Zn elements..
