Summer is in full swing and so is the heat. When temperature reach the 90s, ground-level ozone pollution is likely elevated, too.
Good up high, bad nearby
Ozone can be found in two locations – in the Earth’s upper atmosphere where it protects us from UV radiation and at ground-level on the Earth’s surface.
When ozone is found at ground-level it is a harmful air pollutant that is a key component in smog. Ozone is a harmful air pollutant that affects the respiratory system. Exposure to elevated levels of ozone pollution can cause respiratory problems and aggravate asthma in children. Even healthy adults can experience a 15-20% reduction in lung function from prolonged exposure to low levels of ground-level ozone pollution.
