Objective To explore the overall level, distribution eharaeteristics, and differences in household fine particulate matter (PM) pollution caused by fuel burning in urban and rural areas in China. Methods The relevant articles published from 1991 to 2021 were retrieved and included in this study. The data including the average concentration of household PM and urban and rural areas were extracted, and the stoves and fuel types were reclassified. The average concentration of PM in different areas was calculated and analyzed by nonparametric test. Results The average household PM concentration in China was (178.81±249.91) μg/m. The mean household PM concentration was higher in rural areas than in urban areas [(206.08±279.40) μg/m vs. (110.63±131.16) μg/m ; Z=-5.45, P<0.001] and higher in northern areas than in southern areas [(224.27±300001.66) μg/m vs. (130.11±140.61) μg/m ; Z=-2.38, P=0.017].The north-south difference in household PM concentration was more significant in rural areas than in urban areas [(324.19±367.94) μg/m VS. (141.20±151.05) μg/m, x=-5.06, P<0.001]. The PM pollution level showed differences between urban and rural households using different fuel types (x=92.85, P<0.001), stove types (x = 74.42, P<0.001), and whether they were heating (Z = -4.43, P<0.001). Specifically, rural households mainly used solid fuels (manure, charcoal, coal) and traditional or improved stoves, while urban households mainly used clean fuels (gas) and clean stoves. The PM concentrations in heated households were higher than those in non-heated households in both rural and urban areas (Z=-4.43, P<0.001). Conclusions The household PM pollution caused by fuel combustion in China remains a high level. The PM concentration shows a significant difference between urban and rural households, and the PM pollution is more serious in rural households. The difference in the household PM concentration between urban and rural areas is more significant in northern China. PM pollution in the households using solid fuel, traditional stoves, and heating is serious, and thus targeted measures should be taken to control PM pollution in these households.
