The SEM images of (A) leaf sample from control plants, (C) plants treated with TiO2 NPs at 75 mg L−1, and (E) plants exposed to 150 mg L−1 in no Cd-polluted soil. (G) SEM micrograph of leaf sample from plants treated with TiO2 NPs at 150 mg L−1 in a Cd-polluted soil (20 g/l). The presence of TiO2 NPs in leaf tissues was further confirmed by the EDX spectrum at 4.5 keV (B, D, F and H). OSt: open stomata, CSt: closed stomata, Tr: trichome. Accumulation of TiO2 NPs around stomata and trichomes were shown by arrows.
