The Mobility and bioavailability of thallium from natural and antropogenic origin.
MILLER, Zbyněk
The aims of this study were to precisely describe information about Tl behaviour in soils especially mobility and bioavailability and at given locality to provide analyses of fungi samples to prove found information. This research continues in early findings concerning Tl geochemical position at the locality of Kluky, Czech Republic where an anomaly in Tl concentration in soil is. From the results in can be concluded that Tl is at given locality distributed unevenly and the Tl concentration in almost all the fungi samples was below the detection limit of analytical method used (inductively coupled plasma mass spectrometry, ICP-MS) with the only exception of Macrolepiota procera, Russula claroflava Grove, Hygrophoropsis aurantiaca, Lycoperdon perlatum. In these fungi samples the found bioconcentration factor, BCF (ratio of Tl concentration in fungi and soil) was relatively higher compared to other plant samples at the locality. Therefore the consumption of the fungi from studied locality can not be recommended.
