Аnnotation: An increase in the ozone content in surface air due to climatic changes and an increase in air pollution can lead to an increase in morbidity and mortality. The correlation of abnormally high surface concentrations of ozone in Moscow with morbidity and mortality in different age groups in the summer of 2010 was studied. For comparison, the correlation of moderate ozone concentrations with the frequency of cardiovascular diseases and mortality in a slightly urbanized area in the south of the Kirov region of the Russian Federation is presented. The relationship between high surface concentrations of ozone in Moscow and pneumonia in different age groups is shown. In the groups of men and women aged 31-60 years and older a statistically significant relationship was demonstrated. In the age groups of 15-30 years, there is no connection. Total mortality and mortality in a group over 70 years of age also showed a significant association with surface ozone concentrations, with older people being the most vulnerable. When the average daily maximum allowable concentration of ozone was exceeded for several days in the south of the Kirov region in a slightly urbanized area, the frequency of ambulance calls associated with cardiovascular diseases significantly increased, while the integral indicator of the SOMO35 ozone dose was 678 μg/m3⋅day. Abnormally high air temperatures at low concentrations of ozone and smoke from forest fires did not increase the number of ambulance calls. The validity of the domestic standard of average daily maximum allowable concentration for ozone of 30 μg/m3 was shown.
