   Annual growth rings of Picea abies L., were investigated as a potential archive of past atmospheric Pb pollution. One- to five-year annual wood increments were analyzed for Pb concentrations and 206Pb/207Pb ratios at Jezeri (JEZ), Uhlirska (UHL) and Na Lizu (LIZ), three sites in the Czech Republic, differing in atmospheric Pb loads. Distinct Pb concentration maxima at the two heavily polluted sites (JEZ and UHL) coincided with historical Pb emissions known from inventories of industrial production. No Pb concentration maxima were found at one site, LIZ, situated in a national park 150 km from major pollution sources. Spruce tree rings from JEZ, located just 5 km from coal-burning power stations, contained a large proportion of coal-derived Pb with maximum found indepndently by laser-ablation multi-collector ICP-MS, and single-collector sector-field ICP MS analyses. Annual growth rings of P. abies in Central Europe faithfully recorded historical changes in atmospheric Pb depositions.
