Summary
Abstract: Total concentrations of major and trace elements were determined in samples of
the epilithic lichen Umbilicaria decussata from 24 ice-free areas in coastal
Victoria Land (Antarctica) during 1991 - 2001. Overall average concentrations
of trace elements except Cd were the lowest ever reported for lichens of the
genus Umbilicaria. Specifically, the mean level of Pb in lichen ... View entire text

Quality A composite sample of U. decussata thalli was collected from boulders and rock
outcrops in 24 hours. In each site, a sample of surface soil was collected. In
the laboratory of Baia Terra Nova station, the lichen and soil samples were
dried at 40 degrees C for 36 hrs. The lichens were then sorted to remove
extraneous materials and dead or senescent ... View entire text
