Abstract :As metals and metal compounds have impact on human health, it is important to identify biomonitor plants that can be used to monitor their levels in environmental and biological samples. In this study, two different plants insert ignore into journalissuearticles values(Populus nigra and Cedrus libani); were used as bioindicators. This was evaluated by monitoring heavy metal pollution in Kırşehir province with these plant samples collected from the vicinity of casting factory insert ignore into journalissuearticles values(Casting factory station); and the region where there is no casting factory insert ignore into journalissuearticles values(Boztepe station);. Nickel insert ignore into journalissuearticles values(Ni);, lead insert ignore into journalissuearticles values(Pb);, and copper insert ignore into journalissuearticles values(Cu); levels were determined in the needle, leaves of plants, and soil samples where they grow using High Resolution- Continuum Source Flame Atomic Absorption Spectrometry insert ignore into journalissuearticles values(HR-CS FAAS);. The levels of Ni, Pb, and Cu in Populus nigra were determined to be in the range of 0.87 to 2.59 μg/g, 0.40 to 0.75 μg/g, and 2.27 to 9.66 μg/g, respectively. In analysis of Cedrus libani, metal levels were found the range of 0.44 to 1.12 μg/g for Ni, 0.84 to 3.18 μg/g for Pb and 2.16 to 4.60 μg/g for Cu. The levels of Ni in Populus nigra samples collected from the Casting factory station insert ignore into journalissuearticles values(CFS); insert ignore into journalissuearticles values(2.49±0.09 μg/g); increased compared to the samples collected from the Boztepe station 1.16±0.24 μg/g); insert ignore into journalissuearticles values(p 0.05);. The levels of Ni in Cedrus libani samples collected from the Boztepe station insert ignore into journalissuearticles values(1.03±0.18 μg/g); were higher than that in the samples collected from the CFS insert ignore into journalissuearticles values(0.66±0.24 μg/g); insert ignore into journalissuearticles values(p<0.05);. The levels of Pb in Cedrus libani were determined as 1.74±0.26 μg/g and 1.00±0.16 μg/g for the samples collected from the CFS and Boztepe stations, respectively insert ignore into journalissuearticles values(p<0.05);. The levels of Cu in Cedrus libani were determined as 4.27±0.26 μg/g and 2.87±0.75 μg/g for the samples collected from the CFS and Boztepe stations, respectively insert ignore into journalissuearticles values(p<0.05);. As a result, we suggest that Cedrus libani could be used as biomonitor plants for Pb and Cu and Populus nigra for Ni.
