Geological Survey of Finland (GTK) has investigated sulphur concentrations of peat in Finland since 1975. Research results based on peat sulphur data collected between 1975 and 2004 have been published by GTK in 2009 (Herranen, 2009). The present article additionally draws on new data collected in the Kruunupyy area between 2007 and 2010. The total number of samples is 38 344, which makes the data internationally significant. The mean sulphur concentration of peat in Finland was found to be 0.24%. The highest sulphur concentrations were usually found in samples taken from the basal peat layer. However, high sulphur concentrations were found also in the middle of the peat stratum and in the samples near the surface. The average sulphur concentration of the basal peat was 0.36% and of the surface peat 0.19%.
