Smog is one type of polluted air, which is formed by the presence of particulate matter and gases in the air - they are capable of reacting with sunlight.
The most frequent smog gases are carbon dioxide, carbon monoxide, carbon dioxide, nitrogen oxides, volatile organic components, but also ozone.
The particles found in smog then may include smoke, dust, sand or pollen.
Always, however, very much depends on exactly where we live and what potential air pollution in our environment we have.
Generally, the smaller the particles, the greater the risk. Particles smaller than 10 microns is easily penetrate into the alveoli.
Why bothers ozone
Ground-level ozone is another major contributor to the overall irritant smog. Unfortunately, we have a lot in common with ozone in the high atmosphere, which protects us from UV rays. Ground-level ozone is formed by the reaction exhaust and industrial emissions with sunlight. And smog with high ozone is very irritating for asthma sufferers. Children and adults living in industrial areas or near highways or high speed roads are so burdened with the highest risk of asthma. It was even shown that during the Olympic Games in Atlanta in 1996, when she was stopped by a large portion of traffic, decreased content of ozone in the atmosphere by 28% and emergency room visits of children with asthma was reduced by as much as 42% compared to conventional normal.
