Organic carbon, and major and trace elements reside in labile low-molecular form in the ground ice of permafrost peatlands: a case study of colloids in peat ice of Western Siberia

The low molecular weight fraction of peat porewater is enriched in DOC, anions, oxyanions, alkalis and some trace metals. An increase in the active layer depth can liberate a large amount of labile metals and nutrients from the peat.
