Lichens and mosses as biomonitors of trace elements in a geothermal area (Mt.Amiata, central Italy)

The effectiveness of epiphytic lichens (Parmelia sulcata) and epigeic mosses (Hypnum cupressiforme) as passive monitors of trace elements released by geothermal power plants was evaluated in the Mt. Amiata area (central Italy). The results showed that despite concentrations of most elements (Al, As, Fe, Hg, Pb, Sb, Zn) being higher in lichens than in mosses, both organisms can be used as effective biomonitors of elements of geothermal concern (As, Hg, Sb). © ADAC / Elsevier, Paris
