Toxic Effects of Nickel Oxide Bulk and Nanoparticles on the Aquatic Plant Lemna gibba L.

Figure 3

Fast Chl fluorescence OJIP transients exhibited when L. gibba plants were exposed to 0, 1, 10, 100, and 1000 mg/L of NiO-Bulk or NiO-NPs suspensions (). The symbols used are O, J, I, and P representing, respectively, the fluorescence intensities at 50 μs, 2 ms, 30 ms, and 200 ms.
