The article deals with hygienic evaluation of Ust-Kamenogorsk ambient air pollution with nitrogen dioxide, carbon dioxide, phenol and suspended solids. Ambient air samples were taken in 36 points over 3 days at 6 am, noon, 6 and 9 pm (local time) during warm season (August) and cold season (December). According to the results obtained, the authors divided Ust-Kamenogorsk territory into 2 areas, based on IAP4 (index of air pollution): conditionally dirty area--over 7; conditionally clean area--under 7. Findings are high pollution with suspended solids, nitrogen dioxide, sulphur dioxide and phenol over all territory of the city. But "conditionally dirty" area demonstrated the highest level of ambient air pollution.
