When the blue flame fires up on a fuel range, there’s greater than warmth coming off the burner. Researchers at Stanford College discovered that among the many pollution emitted from stoves is benzene, which is linked to most cancers.
Ranges of benzene can attain increased than these present in secondhand tobacco smoke and the benzene air pollution can unfold all through a house, in keeping with the analysis.
The findings add to a rising physique of scientific proof displaying that emissions inside the residence are extra dangerous than fuel range homeowners have been led to imagine. And it comes as stoves have been dragged into the nation’s ongoing tradition wars.
What researchers discovered
Stanford scientists measured benzene from fuel stoves in 87 California and Colorado properties in 2022 for the paper printed within the journal Environmental Science and Know-how. They discovered each pure fuel and propane stoves “emitted detectable and repeatable ranges of benzene that in some properties raised indoor benzene concentrations above well-established well being benchmarks.”
Stanford researchers in Bakersfield, Ca. function a benzene analyzer at the back of an electrical car. They used an EV as a result of air pollution from fuel exhaust incorporates benzene, which may alter outcomes.

The dangers of benzene have lengthy been identified. The Facilities for Illness Management and Prevention says the chemical is linked to leukemia and different blood cell cancers.
“Benzene types in flames and different high-temperature environments, such because the flares present in oil fields and refineries. We now know that benzene additionally types within the flames of fuel stoves in our properties,” stated Rob Jackson in an announcement. He is the examine’s senior writer and a Stanford professor of earth sciences.
With one burner on excessive or the oven at 350 levels, the researchers discovered benzene ranges in a home will be worse than common ranges for second-hand tobacco smoke. And so they discovered the toxin does not simply keep within the kitchen, it will possibly migrate to different locations, similar to bedrooms.
“Good air flow helps cut back pollutant concentrations, however we discovered that exhaust followers have been typically ineffective at eliminating benzene publicity,” Jackson stated. He says that is the primary paper to investigate benzene emissions when a range or oven is in use.
Researchers additionally examined whether or not cooking meals – pan-frying salmon or bacon – emits benzene however discovered all of the air pollution got here from the fuel and never the meals. That is vital as a result of the fuel business typically deflects concern about air pollution from its gasoline, to respiration issues that may be triggered by cooking fumes.
There aren’t any research on the market that say cooking with fuel will make somebody sick. That is all about rising dangers for sure sicknesses.
The fuel business responds
The American Gasoline Affiliation, which represents pure fuel utilities, routinely casts doubt over scientific analysis displaying that burning pure fuel in properties will be unhealthy. Final 12 months the highly effective commerce group criticized a peer-reviewed examine displaying fuel stoves leak benzene even when they’re turned off. The AGA provided comparable criticism of a 2022 evaluation, which confirmed 12.7% of childhood bronchial asthma instances within the U.S. will be attributed to fuel range use in properties.
The AGA stated in an e mail that its nonetheless evaluating the examine. The Nationwide Propane Gasoline Affiliation, in an announcement to NPR, tried to forged doubt on the peer-reviewed analysis. The NPGA stated the Stanford paper “fails to investigate real-world environments,” and suggests when cooking with fuel “air high quality will be managed by means of quite a few measures, together with air flow choices similar to vary hoods or exhaust followers.”
Medical specialists are beginning to take stands in opposition to cooking with fuel. Nitrogen dioxide emissions have been the most important concern, as a result of they will set off respiratory ailments, like bronchial asthma. The American Public Well being Affiliation has labeled fuel cooking stoves “a public well being concern,” and the American Medical Affiliation warns that cooking with fuel will increase the chance of childhood bronchial asthma.
Gasoline stoves additionally emerged as a tradition battle subject earlier this 12 months after Commissioner Richard Trumka, Jr., of the Shopper Product Security Fee (CPSC), steered that the federal government may contemplate stricter regulation of latest fuel stoves.
Lawmakers within the Republican-controlled U.S. Home of Representatives lately launched and handed two items of laws aimed toward limiting new rules on fuel stoves. One, known as the “Save Our Gasoline Stoves Act” would block the Division of Vitality from implementing proposed vitality effectivity requirements for ranges. One other known as the “Gasoline Range Safety and Freedom Act” would prohibit the CPSC from banning or additional regulating the sale of fuel stoves. It is unlikely both of the payments will turn out to be legislation with Democrats controlling the U.S. Senate and White Home.
What are you able to do about fuel range air pollution?
Gasoline utilities have lengthy researched how fuel stoves pollute indoor air and even developed new types of burners that use much less fuel and emit much less nitrogen dioxide. However producers do not use them, saying they’re costlier, more durable to scrub and customers aren’t demanding them.
However when you’re apprehensive about air pollution from cooking with a fuel range, there are some issues you are able to do. The obvious is to cease cooking with fuel and change to electrical.
There are campaigns underway to encourage individuals to try this, each for well being and local weather causes. The principle ingredient in pure fuel is methane, which leaks into the ambiance all alongside the fuel provide chain and is a potent greenhouse fuel.
Gasoline stoves emit air pollution into your own home and they’re linked to a manufacturing and provide system that leaks the highly effective greenhouse fuel methane throughout drilling, fracking, processing and transport.

Changing a range is dear, although, and there are cheaper interim options. You should buy a conveyable induction cooktop, Shopper Experiences has recommendation right here. There are different plug-in home equipment, similar to toaster ovens, that may cut back the period of time crucial to make use of a fuel range.
And when the time comes to switch your range, there at the moment are authorities subsidies out there by means of the climate-focused Inflation Discount Act handed final 12 months. The nonprofit group Rewiring America has a information right here.
