Abstract:

Without a standard specimen, we analysed the heavy element content of 6 moss species in the King George Island of Antarctica by XRF. They are Andreaea regularis, Bryum muehlenbeckii, Drepanocladus uncinatus, Brachythecium subpilosum, Tortula saxiola and Ditrichum austro georgicum . We found that various plants absorbed varied heavy elements. Even if the same moss, there are the different elements in leaves and stems. Andreaea regularis is possessed of the fewest heavy element varieties in 6 species of bryophyte, but it absorbs Fe more powerfully. Owing to superior environment, we didn't find a lot of poisonous heavy metal elements in bryophyte of Antarctica.
