Gas Stoves and Nitrogen Dioxide

About

Nitrogen dioxide (NO2) is an odorless gas that can irritate your eyes, nose, and throat and cause shortness of breath. Indoor NO2 can come from using appliances that burn fuels such as gas, kerosene, and wood. In people with asthma, exposure to low levels of NO2 may cause increased bronchial reactivity and make young children more susceptible to respiratory infections. Long-term exposure to high levels of NO2 can lead to chronic bronchitis. Studies show a connection between breathing elevated short-term NO2concentrations, and increased visits to emergency departments and hospital admissions for respiratory issues, especially asthma.

Sources of Nitrogen Dioxide

The primary sources indoors are combustion processes, such as:


  • unvented combustion appliances, e.g. gas stoves
  • vented appliances with defective installations
  • welding
  • tobacco smoke
  • kerosene heaters.

Actions You Can Take

Make sure all fuel-burning appliances are properly installed, used, and maintained following all manufacturer's instructions. If possible, use fuel-burning appliances that are vented to the outside. 

  • Gas cooking stoves: Install and use an exhaust fan vented outdoors over gas stoves. Never use the stove to keep you warm or heat your house.
  • Unvented heaters: Use the proper fuel and keep the heater adjusted the right way. Open a window when you are using the heater.
  • Replace gas with induction stove: Learn about induction cooking from Center for Eco Technology and rebates available.

Steps You Can Take To Reduce Exposure

  • If you have an exhaust fan, use it every time you cook!
  • Cook on the back burner –
  • Your face will be further from the fumes. (if you have an exhaust fan, it will work better!)
  • Use the lowest heat necessary.
  • Use oils with a higher smoke point.
  • Refined safflower, sunflower, peanut, ghee and light olive oil are preferred to canola, vegetable oil, extra virgin olive oil or butter.
  • Open the window while cooking if weather permits
  • UNLESS the window faces a busy street.
  • Consider getting an air purifier.   Check out the factsheets from the California Regional Asthma Management and Prevention Programs on Air Cleaners for Asthma Programs  [En Espanol]
  • Use small electronic appliances instead of the gas stove: Microwaves, toaster ovens, crock pots, and rice cookers are good options. Air fryers are not recommended.  
  • Incense vs Candles: Incense emits more dangerous chemicals than candles so if needed, use candles instead of incense as air freshener (HOWEVER: it is always better to use other natural air fresheners such as boiling fresh citrus with cinnamon and water to reduce the amount of harmful chemicals in the air!)
