Using a mobile control station we have studied the air quality in 11 Siberian cities from Irkutsk to Novosibirsk in winter and summer periods. The results obtained show that modern industrial city in winter is not only an island of "heat" but also the island of pollutants. The concentrations of admixtures are much higher at the center of most cities than in their outskirts. An exception is ozone, which, evidently, dies in industrial emissions at the center and recovers on the periphery. In summer, the effect of local circulation substantially weakens, and the difference between parameters measured in the city center and on its periphery is not always observed.
