 According to WHO data, the concentration of ground-level ozone in the atmosphere should not exceed 100 mg/m3. However, in reality, the concentration of this gas in the atmosphere in a polluted environment exceeds 200 ug/m3. For a healthy person, the high concentration of ozone is actually imperceptible. The presence of  increased levels of ozone after lightning is already easily felt by humans due to its characteristic smell. Even higher levels (1000 mg/m3) are observed in the atmosphere in summer. Oxygen is transformed into ozone by the  interaction of nitrogen oxides and unburnt hydrocarbons emitted from automobiles under the influence of  sunlight. At this time, there is 1 mg of ozone in 1 m3 of photochemical smog. This phenomenon is called summer smog. The toxicity of ground-level ozone at this time is much higher than that of cyanic acid and carbon dioxide. It is  poisonous due to its high concentration and has a negative impact on human health. It was determined that in  Tbilisi, under certain meteorological conditions, the concentration of ozone (smog ozone) in the ground air can reach 200 mg/m3. The existence of such a concentration of ozone in the air can last for 17-18 hours, which can  cause great damage to the health of the population, in particular, the respiratory system is mainly affected: It has  been proven that such a large concentration of ozone acts on living organisms as an adequate factor of radiation  exposure. In the conditions of Iong-term observations and monitoring of clinical results, a certain correspondence between the level of ground-level ozone and the spread of infectious diseases, in particular,  respiratory diseases, was revealed.
