Objective To determine the metal contents of lichen species from East Black Sea region of Turkey for investigation of trace metal pollution sourced traffic. Methods The levels of copper, cadmium, lead, zinc, manganese, iron, chromium, nickel, cobalt, palladium in lichen samples collected from East Black Sea region of Turkey were determined by flame and graphite furnace atomic absorption spectrometry after microwave digestion method. The accuracy of the method was corrected by standard ieference material (NIST SRM IAEA-336 Lichen). Results The contents of investigated trace metals in lichen samples were-7.19-22.4 mu g/g for copper, 0.10-0.64 mu g/g for cadmium, 4.03-44.6 mu g/g for lead, 14.5-41.8 mu g/g for zinc, 25.8-208 mu g/g for manganese, 331-436 mu g/g for iron, 1.20-3.01 mu g/g for chromium, 1.48-3.90 mu g/g for nickel, 0.20-3.55 mu g/g for cobalt, 0.11-0.64 mu g/g for palladium. The results were compared with the literature values. Conclusion Some lichen species such as Xanthoparmelia conspersa, Xanthoria calcicola, Peltigera membranacea, and Physcia adscendens are accumulated trace metals at a high ratio.
