摘要
In this study, different chemical plutonium fractions (dissolved in water, connected to carbonates, connected to oxides, complexed with organic matter, mineral acids soluble and the rest) in sediments from the Vistula River estuary, the Gdansk Basin and the Bornholm Deep were determined. The distribution of Pu239+240 in analysed sediments samples was not uniform but dependent on its chemical form, depth and the sediment geomorphology. The highest amount of plutonium exists in middle parts of sediments and comes from the global atmospheric fallout from nuclear tests in 1958-1961. According to all analysed fractions, the biggest amount of Pu239+240 was in the mobile form, connected to carbonate fractions from the Vistula River estuary, the Gulf of Gdansk and the Bornholm Deep sediments.
