Study: Cooking on gas stove more dangerous than you think

A recent study has uncovered alarming findings: cooking on a gas stove can release up to 100 times more harmful particles than emissions from a car exhaust pipe. Researchers at Purdue University discovered that gas stoves emit nano-sized particles, posing a heightened risk of asthma and other respiratory ailments for individuals exposed to them.

Purdue University researchers discovered that gas stoves emit nano-sized particles, increasing the risk of asthma and respiratory illnesses.

Associate professor Brandon Boor from Purdue’s Lyles School of Civil Engineering explained to Southwest News Service that these particles are so minuscule they’re invisible to the naked eye, unlike typical dust particles.


The study revealed that these nano-cluster aerosol particles persistently spread throughout the house from the gas stove. Despite some particles settling on surfaces, the experiments indicated that between 10 billion and 1 trillion particles could enter a person’s airways and lungs while the stove is in use.

To mitigate exposure, the researchers advocate for families to use exhaust fans while cooking, redirecting particles away from the lungs. Dr. Boor suggested that kitchen hoods with automatic activation could be a practical solution since many people forget to turn on exhaust fans.


Looking ahead, the researchers emphasize the importance of reducing exposure to indoor air pollutants and considering nano-cluster aerosol as a distinct category of air pollutant.
