Facts on Pollutants:
Ground-level Ozone (O3)
Ozone is a pale blue gas and has a sweetish odour. Ozone is a strong oxidant, thus making it very reactive and capable of combining with many organic compounds in cells and tissues, as well as with rubber and other materials. Ozone is found in the lower atmosphere (ground-level ozone – also a main component of photochemical smog) and higher up in the stratosphere (stratospheric ozone). Whereas ground-level ozone is bad for your health, stratospheric ozone protects us from ultraviolet radiation. Therefore, ground-level ozone should be minimized, and the natural occurrence of stratospheric ozone should be protected.
