Abstract
Maps of the absolute deposition of heavy metals have been produced on basis of the moss surveys carried
out in the Nordic Countries in 1995. These maps give a much higher resolution than those maps that can be
constructed on the basis of the precipitation monitoring. Calibration factors for the transformation of relative to
absolute values have been developed by plotting concentrations in moss against wet deposition values for the same
site determined from precipitation analysis. The precipitation data used in the project were provided from the
EMEP/CCC database.
