Biomonitoring of indicator species of lichen by EPR spectroscopy

EPR spectroscopy is beginning to occupy a key position in the field of quality control environment. The analysis of the number of paramagnetic centers in the thallus of indicator species of lichen (in a tolerant and sensitive species) was carried out. The number of paramagnetic centers in the lichen thallus was found to depend on the intensity of human impact on habitats of the species studied and their taxonomic affiliation. Possible mechanisms of resistance to atmospheric pollution for tolerant species of lichens were discussed.
