Effect of ammonium nitrate on indicator lichens studied by means of FTIR spectroscopy

Several kinds of indicator lichens undergone to interaction with ammonium nitrate (NH4NO3) have been studied by means of FTIR spectroscopy. It has been established that three types of compounds - alkylnitrate (R-O-NO2), ammonium salts (R-COONH4) and amines (R-NH2) are formed in lichens under the influence of this substance. Their qualitative estimation and investigation of morphological changes in the lichens allow us to define the sensitivity of the studied species to NH4NO3 treatment.
