Use of the Fourier IR spectroscopy for the study of chemical composition changes of Potentilla erecta (L.) Raeusch. under the influence of anthropogenic factors

Making use of IR spectroscopy a study is made of the chemical composition of Potentilla erecta (L.) Raeusch. rhizomes collected in the background and polluted zones of the heat and power plant-3 of Tver at different distances from the pollution source. An increase of the intensity of some IR absorption bands depending on the pollution rate was found to be present in the spectra of P. erecta rhizomes. The results of IR spectroscopy demonstrate the existence of sulphur dioxide in the air emissions of the plant-3 being the main atmosphere pollutant in Tver.
