INDOOR AIR POLLUTION FROM FIREWOOD COMBUSTION IN TRADITIONAL HOUSES OF NEPAL

摘要

Indoor air pollution was investigated during the winter in traditional houses and personal samplers provided to their residents in the Dhading district of Nepal. Results show that the concentration on each floor varies with the position of the staircase. The maximum CO, CO2, SPM, NO2 and HCHO concentrations were 185.5 ppm, 2509ppm, 11.13 mg/m3, 84.7 ppb and 166.9 ppb, respectively in the indoor spaces. This pollution is higher than the standard. The concentrations of CO, CO2 and SPM are highly correlated to the area of the apertures in the kitchen.The iron stove proved highly effective in reducing the indoor air pollution of the investigated house and the residents' samplers.
