Abstract
The concentrations of Cr, Mn, Fe, Ni, Cu, Zn, Cd, Pb and As heavy metals and the heavy metal accumulation levels of these plants were determined in Betula pendula and Populus tremula trees, which are the characteristic trees of Nemrut Crater Lake, the second largest crater lake in the world, and the soil samples surrounding them. Heavy metals are considered to be one of the most dangerous and priority pollutants due to their high persistence and toxicity to plant and animal life in the environment. For this reason, the results obtained will contribute to the studies carried out to determine the uptake of heavy metal pollutants in the environment and the self-healing effort of the polluted environments by applying the phytoremediation method.
