Baseline concentrations of elements in the Antarctic macrolichen Umbilicaria decussata
Entry ID:
Antar_Macrolichen_Umbilicaria
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 ...  Geographic Coverage

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 ...
