Definition - What does Ozone mean?
Ozone is a blue, pungent gas consisting of three molecules of oxygen. As such, it is less stable than oxygen (O2). It’s instability can lead to explosive decomposition. Ozone is a highly oxidative compound and as such, poses a risk of tissue damage to humans, animals and plants when it is present at concentrations exceeding 100ppb. Although Ozone at high altitudes in the atmosphere is beneficial to life on earth, it’s presence at lower altitudes can pose health risks.
