Thallium stable isotope fractionation in white mustard: Implications for metal transfers and incorporation in plants

Popis výsledku v původním jazyce

We studied thallium Tl isotope fractionation in white mustard grown hydroponically at different Tl doses. Thallium isotope signatures in plants indicated preferential incorporation of the light 203Tl isotope during Tl uptake from the nutrient solution. Negative isotope fractionation was even more pronounced in dependence on how much the available Tl pool decreased. This finding corresponds to the concept of isotope overprinting related to a high contamination level in the growing media solution or soil. Regarding Tl translocation in plants, we observed a large Tl isotope shift with an enrichment in the heavy 205Tl isotope in the shoots relative to the roots in treatments with low moderate solution Tl concentrations, with the corresponding fractionation factors, respectively. This finding is probably a consequence of specific plant reactions of Tl replacing K in its cycle. The formation of the S coordinated Tl I complexes, potentially affecting both Tl accumulation and Tl isotope fractionation
