The coal–biomass briquette is an alternative fuel that replaces low-grade coal. It is expected that the use of coal–biomass briquettes will effectively reduce the indoor concentration of sulfur dioxide (SO2) emitted during raw coal combustion. In this study, indoor concentrations of SO2 emitted from combustion of either coal–biomass briquettes or low-grade coal in households in Nanchuan, which is in the rural area of Chongqing City, China, were measured. The acidic gases were collected using passive samplers, and the samplers were taken to the laboratory for extraction and measurement. The SO2 concentrations resulting from the use of coal–biomass briquettes were clearly reduced compared with those resulting from the use of low-grade coal. The concentrations of SO2 to which the inhabitants (housewives) of the houses were exposed were also measured, and were found to be less with coal–biomass briquettes. Although with coal–biomass briquettes exposure concentrations still exceeded the World Health Organization guideline for SO2 (125 μ g m−3), indoor air pollution and adverse effects on human health caused by SO2 could be decreased by substituting coal–biomass briquettes for low-grade coal as a domestic fuel.
