Özet:

 In our work we were interested in the toxicity of fluorine on the various parameters of stress: chlorophyll, proteins, and antioxidant system in the lichen Xanthoria parietina L. Th. Fr., and for this purpose, lichen thalli were treated by sodium fluoride NaF at concentrations of 0, 0.5, 1.0, 5.0 and 10.0 mM, for time scale 0, 24, 48 and 96 h. The analysis results obtained revealed that all the parameters evaluated showed significant variations compared to those of the controls. From the analysis results obtained, it was noted that chlorophyll a Ca, chlorophyll b Cb and total chlorophyll Cab decreased correlating with exposure times to NaF r  -0.785, p  0.001; r  -0.955, p  0.001; r  -0.899, p  0.001, respectively, with a significant increase of Cab ratio p  0.00572 showing that Cb was more affected than Ca. However, hydrogen peroxide H2O2 increased r  0.949, p  0.001. In correlation with NaF concentrations, Glutathione GSH increased r  0.969, p  0.001, while proteins decreased r  -0.872, p  0.001. Furthermore, results showed that catalase activity CAT increased correlating with increasing exposure time of X. parietina to increasing concentrations of NaF. Long-term exposure 48 h -96 h caused a significant decrease in GSH content p  0.02 followed by total destruction at time 96 h.
