There are presented results of the analysis of a risk to public health of cities of Samara and Novokuibyshevsk. We assessed the content of harmful substances in the air at fixed stations located within the city boundaries on a well-ventilated area. The risk to health is calculated in accordance with the R 2.1.10.1920-04. During the period 2014-2015 we fixed the impurity concentration in excess of the average daily maximal permissible concentrations of carcinogens of the first and second classes of danger (benzo[a]pyrene and formaldehyde), as well as ammonia, which has a general toxic effect. The average concentration of phenol and formaldehyde within the territory of the city of Novokuibyshevsk were in the range of the average daily maximal permissible concentrations. Within the city of Samara in the air annual average concentrations of formaldehyde, only slightly exceeding the daily maximal permissible concentrations value of 1.39 in 2015 were registered. The total cancer risk to public health in the city of Samara as a whole for the period 2014-2015 amounted to 2.77·10-4, the total hazard index - 18.35. For the health of the population of the city of Novokuibyshevsk the level of total cancer risk is equal to 1.37·10-4, the total hazard index - 14.64. Hexavalent chromium, formaldehyde and benzene seem to be main pollutants that form the total level of carcinogenic risk to public health in the cities of Samara and Novokuibyshevsk. Copper (I place ranking), contained in large quantities in the emissions of non-ferrous metallurgy is the priority chemical, forming the total index of the risk of developing non-carcinogenic effects in the population of the city of Samara and Novokuibyshevsk. Petrochemicals are related with the values of the total cancer risk and total hazard index unacceptable for public health in cities of Samara and Novokuibyshevsk and require planned measures aimed at improving the environment in the near future.
