| Abstract: | Laser ablation ICP-MS analysis of tree rings provides a rapid and sensitive method for investigating element concentrations and fluctuations in trees along time profiles. Time profiles obtained from pine and birch trees from a strongly polluted area in northwest Russia and a slightly polluted area at the Norwegian-Russian border show that single trees behave rather individualistically in terms of heavy metal contents as observed in the yearly growth rings. The obtained profiles can not be linked to the pollution history of the area. No correlation between pollution levels of the soils and observed metal content in tree rings can be established.
