For millions of Americans, staying indoors offers little protection from dangerous air pollution, according to a new Stanford University-led study. The paper, published Dec. 2 in PNAS Nexus, reveals that gas and propane stoves expose people to substantial amounts of nitrogen dioxide, a pollutant linked to health problems that include asthma, obstructive pulmonary disease, preterm birth, diabetes, and lung cancer. Replacing gas stoves with electric reduces nitrogen dioxide exposure by over a quarter on average across the U.S. and by half for the heaviest stove users, according to the findings. Previous studies have measured nitrogen dioxide pollution from gas stoves, but this is the first study to measure exposure to nitrogen dioxide outdoors and indoors nationally.
