Gas stoves, commonly used for cooking, have been found to significantly increase levels of the carcinogen benzene in the home. A recent study published in the journal Environmental Science & Technology measured benzene emissions from gas stoves and ovens for the first time. The concentrations of benzene were found to exceed the levels considered unsafe by the Environmental Protection Agency (EPA).
The research, conducted by Stanford University’s Doerr School of Sustainability, collected data from 87 homes in California and Colorado. It discovered that using a single gas burner on high or an oven set to 350 degrees Fahrenheit for 45 minutes resulted in kitchen benzene concentrations surpassing those found in secondhand smoke in approximately one-third of the cases measured. Furthermore, the toxic chemical slowly spread throughout the entire home, leading to elevated concentrations for several hours after cooking.
Benzene exposure can have serious health consequences, ranging from acute poisoning symptoms like drowsiness and dizziness to long-term effects such as anemia, weakened immune system, and cancers like leukemia. Notably, a 2018 review found a correlation between benzene exposure and an increased incidence of asthma in children.
The findings of this study add to a growing body of evidence surrounding the harmful effects of gas stoves. Previous studies have shown that gas stoves release pollutants like carbon monoxide and nitrogen dioxide, which contribute to an increased risk of childhood asthma. These alarming findings have sparked public discourse and political controversy, with some suggesting potential regulations on gas stoves. However, such proposals have faced opposition, with arguments about consumer choice and industry interests.
Despite the debate, experts emphasize the need to address the indoor air quality concerns associated with gas stoves. As Rob Jackson from Stanford Woods Institute for the Environment points out, “We would never willingly stand over the tailpipe of a car breathing in its pollution, but we do willingly stand over our stoves, breathing in pollution they emit.”
In an effort to mitigate pollution from gas stoves, the Department of Energy (DOE) has proposed increased energy efficiency standards. However, this has faced resistance, with House Republicans passing bills to counter potential regulations. Industry representatives argue against restrictions, claiming they limit consumer choice.
