Odra River estuary - Opis:
- The content of Cu, Zn, Pb, Co, Cd and Hg accumulated in water, mollusc shells and 15-cm layer of bottom sediments in Lake D1bie, Domi1?a and Roztoka Odrzanska is analysed. The metal concentrations range from 99.82 to 99.88% in bottom sediments, from 0.09 to 0.16% in water and from 0.01 to 0.04% in shells. There is some diversity in distribution of heavy metals in bottom sediments of the study areas due to diversity of heavy metal concentrations in the Odra River Estuary. The metal successions in mollusc shells of the three areas under consideration are identical: Zn > Cu > Pb > Cd > Hg. The distribution of metals in water and mollusc shells indicates greater concentrations of metals in molluscs. In particular, when considering the mass ratio, the water mass is greater than the mass of shells, varying from 3100 (Lake Dąbie) to 20000 (Domiąża). The content of metals in the shells ranges from 7.33% to 22.39% of their total amount in the analysed ecosystems.
