Abstract
Chinese Kang is one of the most important heating facilities at rural houses in China. The biomass materials such as wood and straw are the primary fuels, which release many pollutants. Inadequate ventilation prevents the pollutants from discharging out. In this study, we investigated the indoor air quality at rural houses in severe cold region of China. The pollutants including PM2.5, PM10, TVOC, CO2, CO, SO2, NOX, and NH3 were monitored and the subjective questionnaires on indoor air quality were administered simultaneously. The results shows that PM2.5, PM10, SO2, NOx, and CO2 were the main pollutants at rural houses, with the overproof rates of 97, 79, 99, 63, 71 %, respectively. Nevertheless, the occupants were satisfied with the indoor air quality even the indoor pollutants’ concentrations exceeded the limits specified in the indoor air quality standard. It had a strong correlation between the concentrations of PM10 and PM2.5, and PM2.5 also correlated well with the concentration of CO. It is found that the indoor air quality at rural houses improved greatly with the increasing outdoor temperature in March compared to December and January.
