Table 1.

Ce concentration (µg kg⁻¹ dry weight) in roots, stems and leaves of H. lanatus and D. tenuifolia. Values are means ± standard deviation (SD). Between treatments means with the same letter are not significantly different at Tukey’s test (p ≤ 0.05). In mean comparison between species, ns is not significant at p ≤ 0.05, *, indicate significance at p ≤ 0.05.
