Abstract
The lichensRhizoplaca melanophthalma, Cladonia convoluta, Cladonia pyxidata and the mossesGrimmia pulvinata, Hypnum cupressiforme were analyzed for Pb, Cr, Cd, Co, Ni, Mn, Cu, Zn and Fe using atomic absorption spectrophotometry over a wide area around a coal-fired power plant located in Yatagan. The results were compared with the 210Po concentrations previously measured in the same samples. Correlations between 210Po and trace elements for different moss and lichen species of the same localization and for different localizations for the same species were also studied. In general trace element concentrations do not show significant differences from site to site for all species except Mn in Hypnum cupressiforme and 210Po in Grimmia pulvinata. To discuss the 210Pb level and sources in indicator plants analyzed, also radium contents of surface soil at each sampling station was measured and compared with the average values for similar soil types in the literature.
