Gas and propane stoves linked to 50k cases of childhood asthma, study finds
Stanford researchers measured real-world exposures to nitrogen dioxide from gas stoves in home kitchens across the U.S.
The new study, which researchers at Stanford University published in the journal Science Advances, suggests that the average yearly exposure to nitrogen dioxide from gas and propane stoves in U.S. homes may be close to the World Health Organization’s limit. That yielded an overall estimate of annual exposure to nitrogen dioxide, which the researchers then used to calculate the approximate number of new asthma cases that would be expected as a result, based on past studies. “We found that poor people breathe dirtier air outdoors and — if they own a gas stove — indoors, too,” said Rob Jackson, a co-author of the study and a professor of Earth science at Stanford.
