Gas stoves: A hidden health hazard more harmful than smoking
We are well aware of the negative effects of smoking, both active and passive. However, it turns out there are things we use regularly that might be more harmful. Professor Rob Jackson from Stanford University decided to remove the gas stove from his home due to its harmfulness.
Under Professor Jackson's leadership, the research team discovered that gas stoves emit large amounts of benzene. The results of the study, published in the journal Environmental Science & Technology, suggest that stoves may pose more health risks than cigarette smoke.
Individuals exposed to long-term benzene levels may face an increased risk of developing leukemia and other blood cancers. Although benzene is present in cigarette smoke, its concentration in the air from gas stoves can be higher than that from passive smoking.
Professor Jackson responds to his research findings
I didn’t expect to see pollutant concentrations breach health benchmarks in bedrooms within an hour of gas stove use, and stay there for hours after the stove is turned off - explained Prof. Jackson in a press interview, justifying his decision to remove the gas stove.
This decision followed pollution measurement tests in his home.
Benzene is produced during combustion, so not only smokers or people near fires are at risk, but also those breathing polluted urban air. Research conducted in 87 homes across California and Colorado showed that in about 30% of cases, the use of gas stoves resulted in higher benzene concentrations than those inhaled by passive smokers.
Gas stoves can pose a significant threat
Data published in June 2023 indicates that the benzene issue is not confined to the kitchen, as this gas spreads throughout the house, even reaching the bedrooms. With inadequate ventilation, benzene levels can remain high even after the stove is turned off.
Jackson’s research does not suggest that the age or condition of the appliance significantly affects benzene emissions. The crucial factor was adequate ventilation, but not all range hoods are effective enough. Some devices, rather than expelling the gas, cause it to recirculate.
The findings of Prof. Jackson's team may support those advocating for the removal of gas installations in buildings, particularly since electric induction cooktops do not emit benzene. Previous studies suggest that gas stoves may be responsible for 13% of children's asthma cases in the USA.
On the other hand, it is essential to consider the operational costs and the purchase of induction cooktops over gas stoves, as well as the risks of depending on a single energy source. Power outages could mean no cooking options, an issue not faced with a gas stove.
