Ozone, or smog, is caused by pollution from cars, trucks, power plants, and other industrial sources. It damages lungs and triggers asthma attacks, among other health impacts.

You may have heard of “good” ozone high in our atmosphere, which acts as a protective layer against the sun’s radiation. But ozone is a strong respiratory irritant, so at ground levels ozone is harmful to breathe and can negatively affect your health.

Smog levels in the air climb during hot, sunny days, but high smog concentrations have also been measured in winter months in parts of Wyoming and Colorado where there are high emissions of VOCs and NOx associated with oil and gas development. Smog can travel great distances carried by the wind.
