Gas Stoves Pollute Homes With Benzene, Which Is Linked To Cancer 26

Researchers at Stanford University found that among the pollutants emitted from gas stoves is benzene, which is linked to cancer. "Levels of benzene can reach higher than those found in secondhand tobacco smoke and the benzene pollution can spread throughout a home," reports NPR. From the report: Stanford scientists measured benzene from gas stoves in 87 California and Colorado homes in 2022 for the paper published in the journal Environmental Science and Technology. They found both natural gas and propane stoves "emitted detectable and repeatable levels of benzene that in some homes raised indoor benzene concentrations above well-established health benchmarks." The risks of benzene have long been known. The Centers for Disease Control and Prevention says the chemical is linked to leukemia and other blood cell cancers.
"Benzene forms in flames and other high-temperature environments, such as the flares found in oil fields and refineries. We now know that benzene also forms in the flames of gas stoves in our homes," said Rob Jackson in a statement. He's the study's senior author and a Stanford professor of earth sciences. With one burner on high or the oven at 350 degrees, the researchers found benzene levels in a house can be worse than average levels for second-hand tobacco smoke. And they found the toxin doesn't just stay in the kitchen, it can migrate to other places, such as bedrooms. "Good ventilation helps reduce pollutant concentrations, but we found that exhaust fans were often ineffective at eliminating benzene exposure," Jackson said. He says this is the first paper to analyze benzene emissions when a stove or oven is in use.
Researchers also tested whether cooking food - pan-frying salmon or bacon - emits benzene but found all the pollution came from the gas and not the food. That's important because the gas industry often deflects concern about pollution from its fuel, to breathing problems that can be triggered by cooking fumes. There are no studies out there that say cooking with gas will make someone sick. This is all about increasing risks for certain illnesses.
