In homes where gas stoves are used, air concentrations of nitrogen dioxide, a hazardous chemical compound, often exceed levels recommended by the World Health Organization. This finding has been reported by Daily Mail and echoed by other observers who track indoor air quality.
Gas stoves are common in many countries, including France, Spain, Italy, the Netherlands, Romania, and Slovakia. They are favored for convenience and cost savings. However, Dutch researchers have shown that using a gas stove raises the concentration of nitrogen dioxide in indoor air. The chemical formula for this pollutant is NO2.
Researchers from the Netherlands Organization for Applied Scientific Research observed that NO2 levels rise with longer stove use. They also noted that typical exhaust ventilation systems may struggle to remove these compounds effectively, possibly due to improper operation or installation.
Nitrogen dioxide is a potent oxidizing agent and is toxic even at low concentrations. It can irritate the mucous membranes of the respiratory tract, and exposure may contribute to inflammatory airway diseases such as asthma. Individuals with existing breathing problems may experience worsened symptoms.
British experts who were not part of the Dutch study cautioned that awareness of the dangers may be low among gas stove users. They suggested that manufacturers add clear labeling about potential air pollution. Health professionals recommend using gas stoves only when there is robust ventilation or, alternatively, switching to all-electric cooking options to reduce exposure.

Additionally, practical steps can help manage indoor NO2 risks, such as using exhaust hoods that vent outdoors, keeping doors to other rooms closed while cooking, and ensuring regular maintenance of ventilation systems. Homeowners and renters are encouraged to monitor air quality and consider upgrading to electric stoves when feasible to minimize indoor pollutant exposure.

Recent reviews emphasize that improving kitchen ventilation, selecting energy-efficient and well-vented appliances, and adopting cooking practices that minimize emissions can collectively reduce NO2 exposure in homes. By combining education, labeling, and practical improvements, households can lower the health risks associated with gas stove use. (attribution: recent public health summaries)
Overall, the evidence points to a clear link between gas cooking and elevated indoor NO2 levels, with potential health implications for residents, especially children and those with respiratory conditions. Stakeholders including researchers, manufacturers, and health authorities advocate for heightened awareness, better labeling, and broader adoption of ventilation best practices.
