Benzene: The Toxic Chemical in Both Gas Stoves & Cigarette Smoke - CleanTechnica

A 2023 study published in Environmental Science and Technology revealed that gas stoves emit benzene, a known carcinogen, at levels often exceeding those found in secondhand cigarette smoke. Benzene, recognized as a cancer-causing chemical by the IARC and EPA, can linger indoors for hours after cooking with gas stoves, posing significant health risks. In contrast, induction stoves produce no detectable benzene, and electric coil stoves emit minimal amounts. The study compared air quality in homes using gas versus electric stoves across California and Colorado, highlighting the dangers of indoor natural gas combustion. Further research from Stanford University in 2025 emphasized the heightened cancer risk for children exposed to benzene from gas stoves, especially in poorly ventilated homes. Benzene accumulates not only in kitchens but also spreads to bedrooms and living areas, increasing lifetime cancer risk nearly twofold for children. To mitigate exposure, experts recommend switching to electric or induction stoves, ensuring proper ventilation by opening windows during cooking
