What is ozone?Ozone is a very harmful gas that causes breathing problems. This gas is especially dangerous for children, the elderly and people already suffering from respiratory diseases. This gas damages the lungs, increases asthma attacks and can lead to hospitalization. Ozone gas is not released directly, but is formed due to pollution from vehicles, power plants, factories, etc. Therefore, the amount of ozone is observed in one hour or eight hours a day. But other types of pollution, such as small particles, are observed for the entire 24 hours. Ozone pollution also spreads from one city to another.
