Distribution of sulphur and trace elements in peat. [Literature survey with some additional sulphur analyses]

Abstract

A survey on the literature and contemporary research was made on peat sulphur and trace element studies. Marked variance between different peatlands and peat types has been noted. The available information is still inadequate for generalizations or statistical analysis mainly due to methodological variations and temporal and spatial variations in results. At the moment, the criteria applied in peatland inventories and evaluations are inadequate with respect to peat quality determinations. To some extent the quality of fuel peat should be determined in a mire inventory prior to peatland utilization. The areas over sulphide clay and some sulphate depositions may considerably increase the peat sulphur content. A proposal has been made to include the sulphur content monitoring in the cases where it exceeds 0.3 per cent. The trace elements may also bring about an increase in peat emissions if the deepest peat layers or polluted layers are burnt. The most important elements in this respect are Al, Fe, Mn, Pb, Zn, V, Ni, Hg, Cu, Cr, as well as As and U. The first ten because of the relatively high concentrations and last two because of pollution or toxocity and ore deposit factors. The peat hydrogen ion concentration has a positive  More>>

The peat hydrogen ion concentration has a positive correlation with copper and vanadium. The correlation is positive with the cobalt and nickel contents when the pH is low, and negative at a higher pH. A general peat type correlation shows maximum trace element contents in basal Carex peats with subsoil effects. The peat ash content and the Ti, Pb, V, Cr, Ni and S contents have positive correlations.}
