Is gas stove cooking polluting your kitchen with PAHs more than electric?
Yes. Gas burners and biomass cookstoves throw off more polycyclic aromatic hydrocarbons than electric.
What's actually in it
Burning natural gas, propane, wood, or charcoal makes polycyclic aromatic hydrocarbons (PAHs), a family of compounds linked to cancer and asthma. Electric stoves and induction tops don't burn anything, so they make almost no PAHs themselves. Cooking the food still puts out some, but the burner adds nothing.
Gas stoves also leak unburned nitrogen dioxide and benzene into the kitchen.
What the research says
A 2026 study in Environ Pollut used cobwebs as natural air-pollution samplers in homes with different cooking energy sources. Homes burning gas, kerosene, or biomass had higher PAH loads than homes with electric stoves. The risk score was highest for homes that didn't use a vent hood.
Children and pregnant women are most sensitive to PAHs because of how they affect lung and brain development.
If you can replace, induction cooktops are the cleanest. If you can't, run a strong vent hood any time you cook. Open a window. Use the back burners. Avoid burning food and clean spilled grease before next use.
