Ozone (chemical formula O3) is a compound of oxygen that contains three oxygen atoms. It is produced in the Earth's stratosphere when ultraviolet radiation causes diatomic oxygen (O2) to dissociate into two single oxygen atoms (O). The oxygen atoms then react with an O2 to produce O3.
Health effects
Increased levels of ozone may increase death from respiratory, but not cardiovascular causes.[1]
