Abstract
Peat and moss material for this study was derived from 10 mires. The green portion of S. fuscum (Schimp.) Klinggr. usually had lower contents of Pb than dead moss a few years old. This observation suggests that the moss is not actively taking up Pb from the organic substrate. In peat profiles studied, a distinct enrichment horizon of Pb was found at a depth of 20-50 cm which demonstrates that some leaching from surface moss has taken place. However, the rate of leaching seems to be low, because the regional pattern of lead in Sphagnum remains clear. In dead S. fuscum covered by a thin layer of Mylia anomala (Hook.) Gray, 2 maxima of Pb were present: one at surface 0-2 cm and another deeper in the peat.This publication has 0 references indexed in Scilit:
