Air Pollution

Nitrogen Dioxide

Nitrogen dioxide is common in outdoor pollution, but it can also be found in your house! It's a very harmful gas that can irritate your eyes and lungs. It can also make it easier to get infections in your lungs!
Nitrogen dioxide comes from gas stoves and ovens, water heaters, and fireplaces. It can build up in your house if you don't let enough of it leave through open windows or vents.
