Analysis of thallium accumulation and speciation in S. alba leaves. a Total Tl concentration (solid line with full squares) and the contribution of Tl(III), expressed as a % of total Tl content, (dashed line with full circles) in leaves of white mustard grown in control and 100 (H100), 500 (H500, healthy green leaves; G500 and Y500, green and yellow parts of the affected leaves) and 1,000 μg L−1 of Tl. Values are medians from three to four replicates and whiskers show the range of the data. Values denoted by the same letter did not differ significantly at p = 0.05. b An example of SEC ICP MS chromatogram of white mustard leaf extract (H500). Mobile phase: 100 mM ammonium acetate with 5 mM DTPA, pH 6.2; flow rate 0.75 mL min−1; detected isotope: 205Tl
