Air Quality Awareness Week - Monday


Today we highlight two types of air pollution: ozone and particle pollution.

 

These are two common pollutants found in many parts of the country.

 

Ozone is a colorless and odorless gas. It is the same gas that is found in the ozone layer, high in the earth’s stratosphere, where it protects us from the sun’s ultraviolet energy.  But at ground level where we live, ozone pollution is unhealthy to breathe.

 

Particle pollution, or airborne particle pollution, consists of microscopic particles in the air.  Depending on where you live, it can be a problem in the winter and/or summer. Like ozone, particle pollution is not healthy to breathe.  Particle pollution comes from fires, wood stoves and tailpipes. But it also forms in the atmosphere from pollution from power plants, industries, cars, trucks and construction equipment, meaning people across the country can be exposed. The particles also contribute to haze which blurs the view in many cities and national parks.
