a-f SEC-ICP-MS electropherogram of ¹¹²Cd⁺, ⁶⁶Zn⁺, and ⁶⁴Cu⁺ intensity in A. halleri extracts from roots [control plants (a), plants treated with 45 μM Cd (b), plants treated with 225 μM Cd (c)], and shoots [control plants (d), plants treated with 45 μM Cd (e), plants treated with 225 μM Cd (f)]. The signal from ¹¹²Cd⁺ is designated by the solid line; the signal from ⁶⁶Zn⁺ is designated by the dashed line, and the signal from ⁶⁴Cu⁺ is designated by the dotted line
