Pure fuel stoves generally emit poisonous chemical substances into houses, even when the home equipment will not be in use. A examine revealed immediately in Environmental Science & Know-how discovered that, when researchers took samples from fuel stoves in California, practically all of them had been leaking dangerous ranges of benzene, which is thought to trigger most cancers in people. The quantity emitted from some stoves was as much as seven instances California’s really helpful secure publicity restrict.
Researchers with nonprofit coverage analysis institute PSE Wholesome Vitality took samples from 159 residential fuel stoves in 16 counties all through California. They took samples from stoves fed by three main fuel utilities within the state: San Diego Gasoline and Electrical, Pacific Gasoline and Electrical, and Southern California Gasoline Firm. They discovered benzene in 99% of the samples.
The extent of air pollution from the stoves assorted from pattern to pattern and from county to county, however Los Angeles had the very best degree of indoor pollution. North San Fernando and Santa Clarita Valley houses had benzene ranges 30 instances larger than the California common.
“Whereas these leaks are sometimes too small to odor, they’ll nonetheless impression air high quality and enhance human well being dangers in our houses,” mentioned lead creator Eric Lebel, senior scientist at PSE Wholesome Vitality, in a press launch. “We discovered that simply having a fuel range can create benzene concentrations within the kitchen akin to secondhand smoke.”
The researchers estimated that California stoves are leaking the identical quantity of benzene yearly as 60,000 light-duty gas-powered automobiles, in response to the examine. However these emissions “are presently not included in any statewide inventories,” the summary notes.

“Pure fuel leaks are a supply of hazardous air pollution which have largely been ignored,” Drew Michanowicz, PSE Wholesome Vitality senior scientist, mentioned in a press launch. “Insurance policies that section out fuel home equipment will not be solely good for our local weather, our examine exhibits that these insurance policies additionally present vital public well being advantages by enhancing indoor and outside air high quality.”
This examine comes a month after California’s Air Sources Board voted to section out the sale of pure fuel area and water heaters by 2030. The state has additionally voted to ban the sale of gas-powered autos by 2035 to decrease emissions. Numerous cities throughout the U.S. are additionally transferring to ban fuel hookups as half of a bigger technique to deal with local weather change and decrease air air pollution.
Different analysis has discovered comparable points with fuel stoves. As one author put it in 2020, “Gasoline Stoves Are the Scariest Factor within the Kitchen.” A examine earlier this 12 months discovered that fuel stoves, even when off, leak the greenhouse fuel methane into houses.
