Answer:
Ozone
Explanation:
Ozone can cause damage to people's health as well as to the appearance of cars. Once inhaled, ozone can damage your lungs. Even if it is a small amount, it can still cause throat irritation, shortened breath, coughing, and other symptoms. It can even make current respiratory problems worse. I'm sorry to say I'm not all too sure about how it affects the appearance of cars, but I know for a fact that oxygen and air pollution cannot damage a cars' exterior.
Hope this helps ya :D
