Isotopic Tracing of Thallium Contamination in Soils Affected by Emissions from Coal-Fired Power Plants

Popis výsledku v původním jazyce

Here, for the first time, we report the thallium (Tl) isotope record in moderately contaminated soils with contrasting land management (forest and meadow soils), which have been affected by emissions from coalfired power plants. Our findings clearly demonstrate that Tl of anthropogenic (high-temperature) origin with light isotope composition was deposited onto the studied soils, where heavier Tl (?205Tl ~ -1) naturally occurs. The results show a positive linear relationship (R2 = 0.71) between 1/Tl and the isotope record, as determined for all the soils and bedrocks, also indicative of binary Tl mixing between two dominant reservoirs. We also identified significant Tl isotope variations within the products from coal combustion and thermodesorption experiments with local Tl-rich coal pyrite. Bottom ash exhibited the heaviest Tl isotope composition (?205Tl ~ 0), followed by fly ash (?205Tl between -2.5 and -2.8) and volatile Tl fractions (?205Tl between -6.2 and -10.3), suggesting partial Tl isotope fr
