Our results showed that both ZnO and Fe NPs improved plant growth, and photosynthetic attributes by minimizing oxidative stress in lettuce plants through the stimulation of antioxidant enzyme activities.

The Fe NPs treatment (20 mgL<sup>-1</sup>) increased the dry weight of shoots and the roots and fresh weights of shoots and roots by 53%, 76%, 42%, and 70%, respectively. Application of both NPs reduced the oxidative stress caused by Cr, as evident by the findings of the current study, <i>i.e.,</i> at the ZnO NPs (100 mgL<sup>-1</sup>) and Fe NPs (20 mgL<sup>-1</sup>), the EL declined by 32% and 44%, respectively, in comparison with respective control plants.

Application of ZnO NPs at 100 mg L<sup>-1</sup> and Fe NPs at 20 mg L<sup>-1</sup>, improved the Zn and Fe contents in plant leaves by 86%, and 68%, respectively, as compared to the control plants. This showed that the exogenous application of these NPs helped in Zn and Fe fortification in plants.
