The paper presents the results related to complex assessment of Kazan city air quality by chemical indicators and by photosynthetic activity inhibition level of blue spruce (Pícea pungens). It has been shown that on chemical indicators the air quality fluctuates from high to very high polluted level, and the greatest contribution to air pollution is made by dust, carbon oxide, nitrogen dioxide and formaldehyde. It has been shown that blue spruce’s (Pícea pungens) slowed-down fluorescence indexes are good indicators of atmospheric air pollution. A strong correlation has been revealed between the content of carbon oxide, nitrogen dioxide and dust in the air and the slowed-down fluorescence indexes.
