Gas Stoves Could Leave Your Lungs Vulnerable to Nitrogen Dioxide

FRIDAY, May 3, 2024 (HealthDay News) -- People in homes with gas or propane stoves regularly breathe in unhealthy levels of nitrogen dioxide, a new study says.

Typical use of these stoves increases exposure to nitrogen dioxide (NO2) by an estimated 4 parts per billion, averaged over a year, researchers report.

That’s three-quarters of the way to the NO2 exposure level deemed unsafe in outdoor air by the World Health Organization, researchers noted.

“That’s excluding all outdoor sources combined, so it makes it much more likely you’re going to exceed the limit,” lead researcher Yannai Kashtan, a doctoral student in Earth system science at Stanford University, said in a news release.
