Abstract


In the present work, lichen Xanthoria parietina is used as an accumulator of four heavy metals in the Setif region. The sampling of biological material is performed using a natural sensor, represented by a lichen species corticolous, X. parietina, from 16 stations located in proximities of 04 highways (RN 5, NR 9, RN 28 and RN 74). Samples were taken and four heavy metals (Cr, Zn, Cu and Ni) were selected for the analysis. The metal contents recorded in the various stations are very variable. The (Cr. Zn and Ni) are high in all the stations relative to normal levels; these stations are characterized by high traffic and / or an intense industrial activity. For the Cu contents, recorded for all stations, are low. These results show a tolerance of X. parietina the metal stress and therefore its efficiency to be used in biomonitoring programs of air quality.

Keywords: Heavy metals, Biomonitoring, Bioaccumulation, Xanthoria parietina, Setif, Algeria.
