Field measurement of winter air quality of the typical rural building in southwest of Shandong Province

For investigating the winter air quality of the typical rural building in southwest of Shandong province, concentrations of particles (PM1.0), gaseous pollutants (CO and CO2) in the main room and courtyard were measured. Concentrations of contaminants in both rooms appeared consistent trend, with peak values in the three periods of mealtimes. Contaminants in the main rooms mainly derived from the courtyard, as well as contribution of occupants' activity. Using stove to warm the main room produced substantive gaseous contaminants, especially higher concentration of CO when stove was quenching. Comparing biomass and fossil fuel, the former produced more particles, while the latter made more gaseous pollutants. In addition, setting off fireworks seriously contaminated air quality of rural buildings, and concentrations of contaminants depended on the patterns of fireworks.
