The Atmosphere

The Ozone Layer

If ozone is good for us, why do we hear about ozone alerts and “bad ozone”

Ozone is great when it is high up in the atmosphere and doing its job of protecting us from radiation, but when it is down near ground level it is toxic to those who breathe it in. Car exhaust fumes and other sources of pollution include ozone, which is seen in smog. Ozone pollution can make people sick and damage crops. Small amounts of ozone are also produced by electrical storms (if you have ever performed electricity experiments in a high school or college laboratory, you might be familiar with the ozone smell produced by even small bolts of electricity).
