According to the research the species of lichens such as Parmelia sulcata, Parmeliopsis ambigua, Phiscia stellaris, Xanthoria parietina are founded on example of small town. Values of clear air index correlated with the average content of sulphur dioxide in the air. These measurement points correspond to residential areas and regions of the objects of food industry. Two zones zero projective coverage are selected. These most polluted zones corresponded to the location of the metallurgical industry and heat electropower station. The roof production and abrasive industry do not show a significant increase in the concentration of sulfur dioxide in the contiguous territory. By method lichen indication on example of small city two zones lichen deserts (sulfur dioxide concentration greater than 0.3 mg/m3) and one area of critical pollution (sulfur dioxide concentration of 0.1 -0.3 mg/m3) were founded. The largest area of air pollution allegedly linked to the activities of plants. Thus metallurgical industry and heat electropower station can be called major air pollutants in small towns.
