Ozone depletion

Ozone depletion

Ozone depletion. O 3 very pale bluish gas very powerful oxidising agent pungent smelling odor absorbs UV light detection : [O 3 ] in a sample of air can be measured using UV spectroscopy; the more UV is absorbed the higher [O 3 ] in upper stratosphere; 15 to 45 km. Ozone depletion.
