Content of glutathione (a) and L-ascorbic acid (b) in oakleaf lettuce seedlings affected by Ag, Au and Pt nanoparticles applied to the leaves in different concentrations as aqueous colloidal solutions. Control plants were sprayed with deionized water. *Denotes significant differences (p ≤ 0.05) between particular nanometal and unexposed control, means for concentration of given nanometal with no letters are not significantly different at p ≤ 0.05, comparisons were performed by Fisher’s LSD test. Bars represent standard deviations (± SD)
