The mean concentrations of Cd, Co, Cr, Cu, Ni, Pb and Zn in Hypnum cupressiforme from southern Sweden are larger in the south-west than in the north-east. The difference is highly significant for Pb, Cu and No. The concentration of Pb and Cd in Hylocomium splendens is more than ten times larger in south-western Sweden than in northern Norway and also for other heavy metals (except Mn) the differences are considerable. No differences between northern and southern scandinavia in the concentrations of Ca, K and Mg have been measured. Heavy metal concentrations of Sphagnum magellanicum in ombrotrophic bogland sites coincides well with the concentrations of Hylocomium splendens from woodland sites of the same area. The deposition of heavy metals/hectare/year has been calculated. The only probable explanation of the measured gradients is that the deposition of heavy metals, originating from human activity is much greater over southern scandinavia, particularly south-western Sweden, than over northern Scandinavia. The regional basic concentrations reported in this article reflect the fall-out from an atmospheric pool to which both neighbouring and remote sources contribute.Read More
