In the current discourse, the environmental impact of natural gas ovens on the climate has garnered attention, particularly due to the passive leakage of methane, a potent greenhouse gas. While the implications for climate change are alarming, the repercussions on indoor air quality often escape homeowners' awareness. This blog delves into the lesser-known air quality issues stemming from the use of gas ovens.
NOX - A Silent Intruder
Nitrous Oxides, or NOX, pervasive air quality pollutants prevalent in smog, pose a silent threat. Formed during the combustion of hydrocarbon-based fuels, including natural gas containing methane and nitrogen, the stove flame's reaction can engender NOX. Studies indicate a staggering surge of 25–39% in indoor NOX levels attributable to gas stoves, underscoring the concealed peril within households.
Carbon Monoxide - The Covert Culprit
Complete combustion of natural gas results in benign carbon dioxide; however, incomplete combustion gives rise to the insidious carbon monoxide. Elevated levels of carbon monoxide, witnessing a surge of 21-30% with gas stove usage, pose a concealed hazard. Burner malfunctions leading to incomplete combustion coupled with inadequate ventilation or an absence of a stove exhaust system allow carbon monoxide to linger, accumulating to perilous concentrations.
Particulate Matter - The Airborne Intruders
Particulate Matter (PM), describing airborne solid or liquid particles, emerges as a subtle adversary. The EPA categorizes PM into PM2.5 and PM10, denoting particles of 2.5 microns or smaller and 10 microns or smaller, respectively. Cooking and combustion activities generate particles, evidenced by an observable spike in PM2.5 post-cooking during field observations. Mitigation strategies involve deploying exhaust hoods or HEPA air purifiers to counteract this airborne intrusion.
Strategies for Elevated Air Quality
Embracing the ethos that "the solution to pollution is dilution," homeowners can proactively enhance indoor air quality amid gas stove usage. Mechanical ventilation, such as an exhaust hood, proves instrumental in diminishing contaminants like particulate matter arising from culinary endeavors. Regular maintenance of gas-operated appliances serves as a bulwark against carbon monoxide risks emanating from malfunctioning stove burners. Should concerns persist, seeking the expertise of an indoor air quality consultant, such as Building Performance Solutions, becomes paramount for a comprehensive resolution.
