BIOINDICATION STUDIES IN CIS-BAIKAL. REPORT 2. FEATURES OF EPIPHYTIC LICHENS DISTRIBUTION IN INDUSTRIAL CITY
For the first time the paper presents the materials on the sensitivity of lichens to human impacts in the cities with highly developed industry. Usolie-Siberian (Irkutsk region) is the city with the high level of air pollution. The increased content of benzopyrene, formaldehyde, nitrogen dioxide and particulate matter is noted. The gardening "Lilacs"(9) is located 3 km from the site Khimprom.
