摘要：The aim of this study is investigated the levels of lead pollution in Peltigera praetextata (Sommerf.) Zopf. lichen species hanged all the way 40 km highway situated between Giresun and Ordu provinces. The samples were hanged to total 8 stations situated 100 meter inside from the road and the roadside with 10 km distances. In each station, the lichen samples were collected at the end of 45 days. The amounts of lead (Pb) in the samples were determined with Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES). ·The results showed that there were statistically significant differences in the amounts of lead measured in all the stations when compared with the control group (P<0,05). Besides, lead pollution in the samples collected from the stations situated nearby of the Giresun and Ordu provinces is higher according to the other stations. These results showed that P. praetextata species will be used as a biological indicator to determine of lead pollution.
