Bioaccumulation of polonium (210Po), uranium (234U, 238U) isotopes and trace metals in mosses from Sobieszewo Island, northern Poland
University of Gdańsk, Faculty of Chemistry, Sobieskiego 18, Gdańsk, POLAND
The objective of this study was determination of the polonium (210Po), uranium (234U and 238U) radionuclides and trace metals (Pb, Fe, Zn, Cu, Ni, Cd, Hg) concentrations in mosses samples from Sobieszewo Island near the phosphogypsum waste dump in Wiślinka (northern Poland). The obtained results revealed that the concentrations of 210Po, 234U, and 238U in the two analyzed kinds of mosses: Pleurozium schreberi and Dicranum scoparium were similar. Among the analyzed trace metals the highest concentration in mosses was recorded for iron, while the lowest for nickel, cadmium and mercury. The obtained studies showed that the sources of polonium and uranium isotopes, as well as trace metals in analyzed mosses are air city contaminations transported from Gdańsk and from existing in the vicinity the phosphogypsum waste heap in Wiślinka (near Gdańsk).
Key words: polonium / 210Po / uranium / 234U / 238U / trace metals / mosses / Sobieszewo Island / northern Poland
