HOUSEHOLDS FUELS STRUCTURE AND EFFECT ON INDOOR AIR QUALITY IN WESTERN CHINA

Abstract:

Under the leadership of the Ministry of Agriculture (MOA), and the Ministry of Commerce (MOFCOM), China Association of Rural Energy Industry (CAREI) has been granted to implement the Sino-Dutch co-project named “Promotion of Rural Renewable Energy (RRE) in Western China” from 9 January 2003 to 31 December 2007. in this project renewable technologies and products were applied to farmers such as biogas digester, solar water heater and high-efficient biomass stoves, which improve the indoor air quality due to the energy structure was changed and the energy efficiency was increased greatly. In order to find proof for the contribution from renewable energy and to explore the relation between household fuel structure and indoor air quality in rural regions. The concentration of SO2, CO and PM2.5 in kitchens of 200 households randomly selected in 6 villages of western China were monitored during period before all the renewable technologies and products was applied and after those are applied and operated well. The data shown that The concentration of SO2, CO and PM2.5 were accessed the national standard greatly before the renewable technologies and products was applied, but decreased greatly, some are lower that the national standard after those were applied to the households. It indicated that the renewable energy will give great contribution for the indoor air quality improvement.
