However, closer to the ground, it causes damage to the lung tissues. Tailpipes, smokestacks, and other sources, greatly contribute to the rise of Ozone levels in especially the troposphere.
Impact on Human Health

The groups, who are among the worst affected ones of Ozone pollution, are young children and adolescents, the elderly people, those working outdoors, and those with either lung or heart conditions. Exposure to ozone definitely reduces the lifespan of a person, causes short or long term respiratory problems and weakens our cardiovascular system.

This means that the amount of Ozone that is being released into the atmosphere is being reduced, and the checks installed by the government had worked well.
