Finding F-0664

“During intensive monitoring periods, the 405 Monitor measured median 48-h average NO2, NO, and NOx concentrations of 6.0, 9.3, and 9.5 ppb in electric stove homes versus 16.0, 39.7, and 59.1 ppb in gas stove homes, representing reductions of 63%, 76%, and 84%, respectively (all p < 0.001).”

Structure

Factor: Nitrogen dioxide (NO₂)
Population: households
Setting: dwelling with an electric stove, US
Study design: comparison of households with electric stoves (electrification programme) and households cooking with natural gas or propane in the rural San Joaquin Valley, California: about one month of personal air monitor measurements and 48 hours with reference-grade instruments in each home, with CO2 above the cooking surface as a stove-use proxy (class 4)
Effect: median 6.0
Averaging time: median 48-hour average
