The ability of transplanted lichen Pseudevernia furfuracea to biomonitor specific airborne pollutants (heavy metals and polycyclic aromatic hydrocarbons-PAHs) was investigated at five stations with different traffic densities in Viterbo, Italy. Exposed lichen showed high levels of all analysed pollutants; greatest values were for Zn (147-252 μg/g dw), Pb (24.9-34.6 μg/g dw), fluoranthene (37-107 ng/g dw), pyrene (23-124 ng/g dw). Comparison between contaminants concentration in lichens before and after exposure showed "accumulation" or "severe accumulation" rates in more than 90% of each substance. Besides, Pseudevernia furfuracea accumulated airborne PAHs in a manner that was proportional to traffic density. © 2009 Springer Science+Business Media, LLC.

Abstract
The ability of transplanted lichen Pseudevernia furfuracea to biomonitor specific airborne pollutants (heavy metals and polycyclic aromatic hydrocarbons-PAHs) was investigated at five stations with different traffic densities in Viterbo, Italy. Exposed lichen showed high levels of all analysed pollutants; greatest values were for Zn (147-252 μg/g dw), Pb (24.9-34.6 μg/g dw), fluoranthene (37-107 ng/g dw), pyrene (23-124 ng/g dw). Comparison between contaminants concentration in lichens before and after exposure showed "accumulation" or "severe accumulation" rates in more than 90% of each substance. Besides, Pseudevernia furfuracea accumulated airborne PAHs in a manner that was proportional to traffic density. © 2009 Springer Science+Business Media, LLC.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
