Abstract [en]

The surface sediments in the central Bothnian Bay are contaminated with antropogenic Pb. Preindustrial sources of the Pb pollution are anthropogenic atmospheric Pb, where the main Pb source is combustion of gasoline, and ore from the Laisvall mine which is processed in the smelter Rönnskärsverken. Because the Pb isotope composition of these possible sources are known, an attempt was made to trace the origin of the antropogenic Pb by studying the Pb isotope composition of sediments. The results show unequivocally that Laisvall Pb is not the source of the pollution. The enrichment of Pb in surface sediments is caused by atmospheric deposition of Pb additives from gasoline. Lead emitted from Rönnskärsverken is deposited relatively close to the smelter, and has not reached central Bothnian Bay in traceable amounts.
