Abstract:
Objective To evaluate the influence of gaseous combustion products of the natural gas (NG), liquefied petroleum gas (LPG) and coal on the indoor air quality. Methods The three kinds of domestic fuels were burned in the designed experimental rooms and the concentrations of SO2, NO2, CO and formaldehyde in the indoor air were determined according to the standard methods at the same time, the emission characteristics of SO2, NO2, CO in these fuels were analyzed also. Results The emission level of CO was the highest in the four combustion products of all three fuels. According to the average daily usage in general families in China, the emission of CO in the coal combustion was much higher than that in combustion of NG and LPG. The unit emission of CO of the coal for house use could reach 30 136 mg/kg, much higher than LPG(8 725 mg/kg)and NG(2 755 mg/kg). The unit emissions of NO2 of LPG combustion (42.69 mg/kg) was higher than the coal and NG (20.01 mg/kg, 11.87 mg/kg), so in the unventilated rooms it could still make the indoor air quality exceed Chinese indoor air quality standard limits. Conclusion Burn of NG or LPG in the kitchen could also cause indoor air pollution.
