Özet

Thalli of the lichens Pseudevernia furfuracea, Usnea longissima, Lobaria pulmonaria, and Peltigera praetextata were taken from unpolluted areas and transplanted to a downtown site in Erzurum, Turkey. Heavy metals copper (Cu), chromium (Cr), zinc (Zn), lead (Pb), nickel (Ni), and iron (Fe) were measured after an 8 month exposure period. Changes in the heavy metal concentrations were observed during the exposure period in lichen species and in both locations. Heavy metal concentrations were significantly higher in Peltigera praetextata than the other species at the location nearest to the junction crossroads. Peltigera praetextata may be considered a good indicator. These results can be attributed to the effect of atmospheric pollutants on the transplanted lichens.
