The article is concerned with an assessment of patterns of lower atmosphere ozone concentrations (LOC) and the relevant meteorological factors, as well as the role of the latter as risk factors for the incidence of medical emergencies, using population of the city of Simferopol as an example. Throughout 2017, average daily LOC in the air substantially exceeded MAC; the seasonal pattern was characterized by two maximums, that is, during the spring and summer periods. The LOC dependence on temperature, humidity, and atmospheric air pressure proved to be statistically significant; its levels were found to be significantly higher with the northeasterly wind compared to the southwesterly (onshore wind). To assess the effects of LOC and other meteorological factors on population health, daily values were compared with the daily statistics on incidence of medical emergencies with respect to the respiratory and cardiovascular systems derived based on the number of emergency ambulance calls in Simferopol. The number of the ambulance calls was determined to be significantly dependent on LOC and the temperature and humidity of the atmospheric air for asthma attacks and acute coronary syndrome and on wind speed for arrhythmia.
