The study of the lichenoflora of three urban territories (Donetsk, Shakhtarsk, Torez) with high anthropopression chosen by the index of average annual concentration of air pollutants yielded 28 species of lichens related to 16 genera, 9 families. The observed data on the spread of lichens adequately reflect the level of air pollution which is corroborated by instrumental investigation. Thus, it is advantageous to use lichens as biomarkers of pollution for anthropogenically transformed environments.
