Toxicity of Superparamagnetic Iron Oxide Nanoparticles on Green Alga Chlorella vulgaris
Figure 8
Change of different photosynthetic-based fluorescence parameters for algal cells of Chlorella vulgaris exposed during 72 h to different concentrations of SPION-1 (Fe3O4), SPION-2 (Co0.2Zn0.8Fe2O4), and SPION-3 (Co0.5Zn0.5Fe2O4). Maximal PSII quantum yield: ; ratio between the number of active PSII reaction centers and light harvesting Chl antenna size: ABS/RC; relative variable fluorescence yield at transient: ; performance index of PSII photochemical activity: P.I.
