Data on species composition and background concentrations of some elements in moss samples from Livingston Island (Antarctica)

摘要

During an expedition on Livingston Island at the end of 2001, 17 moss species were collected. Together with those collected in 1998/1999 23 moss species have been found so far around the Bulgarian Base Station. For the purposes of the biomonitoring, samples of Sanionia georgico-uncinata were collected from 8 sample plots. The concentrations of P, K, Ca, S, Na, Mg, Mn, Fe, Al, Zn, Cu, Pb, Cd, Co, Ni, Cr, As, and Se were analyzed using ICP-AES. The mean concentrations of Mn, Fc, Co, Ni, Cd and Pb accumulated in Sanionia nncinala used in a previous study were in the ranges of these metals found for S. georgico-uncinata in this study, whereas Zn was very close to the minimum value, and content of Cu (19 mg/kg) was 2-fold higher than the maximum value ofS. georgico-uncinata. Using the current results for background concentrations of heavy metals and toxic elements in Europe it could be assumed mat the region around the Bulgarian Base is not heavily polluted.
