Lichens are efficient accumulators of chemical elements which are taken up from substrate solutions, deposited aerosols, water vapour and rain. Their thalli particularly those with.soredia or .isidia provide an effective surface for uptake (Seaward, 1992). Recent studies suggest that there is global contamination of air, water and soil by trace metals (Nriagu and Pacyna, 1988). Several workers have suggested a possible role of lichens in pollution monitoring and biogeochemical studies (Tuominen and Jaakkola, 1973; Garty, 1993). The present study will provide a comparative account of metal content of different lichen thalli growing on different ecological habitats, in and around the Maitri Staion of the Schirmacher Oasis, East Antarctica.
