Science Advances report also finds people of color and low-income residents in US disproportionately affected

Using a gas stove increases nitrogen dioxide exposure to levels that exceed public health recommendations, a new study shows. The report, published Friday in Science Advances, found that people of color and low-income residents in the US were disproportionately affected.

Indoor gas and propane appliances raise average concentrations of the harmful pollutant, also known as NO2, to 75% of the World Health Organization’s standard for indoor and outdoor exposure.

That means even if a person avoids exposure to nitrogen dioxide from traffic exhaust, power plants, or other sources, by cooking with a gas stove they will have already breathed in three-quarters of what is considered a safe limit.

“When you’re using a gas stove, you are burning fossil fuel directly in the home,” said Yannai Kashtan, lead author of the study and a PhD candidate at Stanford University. “Ventilation does help but it’s an imperfect solution and ultimately the best way is to reduce pollution at the source.”

    Nitrogen dioxide irritates the airways and can exacerbate respiratory illnesses such as asthma. The Stanford study estimates that chronic stove-based nitrogen dioxide exposure is linked to at least 50,000 cases of pediatric asthma in the United States each year. The research, which measured NO2 in more than 100 homes before, during, and after gas stove use, found that pollution migrates to bedrooms within an hour of the stove turning on, and stays above dangerous levels for hours after use.

    The results also highlight the unequal racial and socioeconomic burden of exposure. The study found that American Indians and Alaska Natives are exposed to 60% more NO2 from gas and propane stoves than the national average. Black and Latino or Hispanic households breathe in 20% more NO2 from their stoves.

    People in households making less than $10,000 a year are breathing NO2 at rates more than twice that of people in households making over $150,000.

    “People in poorer communities are more at risk because their outdoor air is bad and and in many ways their indoor air is worse,” said Jackson. Low-income communities and communities of color are more likely to live near highways, ports, industrial sites and other polluting zones.

    “There’s an underlying assumption that people are only using their stove or oven to cook and to prepare meals,” said Diana Hernandez, sociologist at Columbia University who was not involved in the Stanford study. A recent survey conducted by Hernandez and her team found that over 20% of New Yorkers used stoves or ovens to heat their homes.

    Gas stoves also emit methane, a potent greenhouse gas, and cities across the US are adopting building electrification measures that would phase out gas stoves in new homes.
