In recent research conducted by Stanford University, an alarming revelation has come to light regarding the presence of the carcinogenic compound benzene in households using gas stoves.
Benzene, linked to an increased risk of leukemia and other blood cell cancers, has been found to enter millions of homes through the use of gas cooking appliances.
The study suggests that even running a single burner on a gas stove at high heat or setting a gas oven to 350 degrees Fahrenheit can lead to indoor benzene levels exceeding those seen in secondhand smoke.
The research, published June 15 in Environmental Science & Technology, also underscores the persistent nature of benzene in the home environment, with the compound remaining in the air for hours after the gas stove has been used.
These findings shed light on the potential health risks associated with gas stove emissions and emphasize the need for increased awareness and the implementation of measures to mitigate exposure.
Senior study author Rob Jackson, the Michelle and Kevin Douglas Provost Professor and Professor of Earth Systems Science at the Stanford Doerr School of Sustainability, said, “Benzene forms in flames and other high-temperature environments, such as flares in oil fields and refineries.”

“We now know that benzene is also formed in the flames of gas stoves in our homes. Good ventilation helps reduce pollutant concentrations, but exhaust fans have often been ineffective in eliminating benzene exposure.”
A recent study has highlighted increased indoor concentrations of the carcinogenic compound benzene resulting from the use of gas stoves that exceed levels seen in passive smoking.
The research further revealed the potential spread of benzene to different rooms in homes, particularly noting concentrations in bedrooms that exceeded established health standards. In particular, home fume hoods have been found to be ineffective in reducing benzene levels, even when vented outdoors.
The study’s recommendations support the adoption of portable induction cooktops or electric cookware to minimize exposure to pollutants from gas stoves.
Financial incentives such as state and local rebates and federal tax credits are designed to help offset the cost of replacing gas appliances.
This groundbreaking research represents the first comprehensive analysis of benzene emissions during stove and oven use, revealing that gas burners emit significantly higher levels of benzene compared to electric stoves, while induction cooktops emit none.
The findings highlight the environmental and health risks associated with gas stoves and highlight the benefits of alternative cooking methods.
