Ozone Information
Naturally occurring ozone in the upper atmosphere protects the earth from the sun's harmful rays. Ground-level ozone is an irritant that damages lung tissue and aggravates respiratory disease. The pollutant is formed when heat and sunlight mix with Volatile Organic Compounds (VOCs) and nitrogen oxides (NOx) in the lower atmosphere. Ozone can trigger a variety of health problems. Those most susceptible to ozone include children, the elderly and individuals with pre-existing respiratory problems. Even healthy young adults may experience respiratory problems when exposed to low levels of ozone.
