Gas Range/Oven Emissions Impact Analysis: Appendix. Final Report July 1985-December 1987

摘要

Ten older homes in Wisconsin were selected to participate in the pilot project to determine if field measurements of NO2 and CO on gas ranges vary significantly from those reported in the literature, and if use of both vented and unvented gas appliances can be apportioned to determine separate impacts. Continuous NO2 and CO measurements were taken in several locations within each home during two measurement periods. Homeowners also kept detailed diaries of gas appliance use. The results indicate that the gas oven was frequently implicated in the small group of case study homes as a source of peak hourly average NO2 concentrations; NO2 emission rates were as much as a factor of two greater than those previously reported. The study also found that routine service adjustments on the ten range set resulted in statistically significant decreases in CO and NO2 emission rates following servicing. This finding implies that some servicing of the gas range may be desirable and have an impact on indoor levels of NO2 and CO.
