Ozone in the Stratosphere

  • Ozone in the boundary layer causes adverse health effects
  • Ozone in the stratosphere, however, in necessary for our survival
    • absorbs UV radiation before it reaches the ground
    • maximum concentrations of about 12 ppm are at about 25 km AGL

Anticipated health effects due to ozone layer depletion:

  • increase in skin cancer cases
  • increase in eye cataracts and sun burns
  • suppression of the human immune system
  • an adverse impact on crops and animals due to increased UV radiation reaching the ground
  • reduction in the growth of ocean phytoplankton
  • cooling of the stratosphere that could alter stratospheric wind patterns, possibly affecting the production (and destruction) of ozone.
