Atmospheric PM10 were measured for 12 months at 18 sites along a 2500聽km profile across northern China. Annual mean PM10 concentrations in urban, rural village, and rural field sites were 180聽卤聽171, 182聽卤聽154, and 128聽卤聽89聽渭g/m3, respectively. The similarities in PM10 concentrations between urban and rural village sites suggest聽that strong localized emissions and severe contamination in rural residential areas are derived from solid fuels combustion in households. High PM10 concentrations in Wuwei and Taiyuan were caused by either sandstorms or industrial activities. Relatively low PM10 concentrations were observed in coastal areas of Dalian and Yantai. Particulate air pollution was much higher in winter and spring than in summer and fall. Multiple regression analysis indicates that 35% of the total variance can be attributed to sandstorms, precipitation and residential energy consumption. Over 40% of the measurements in both urban and rural village areas exceeded the national ambient air quality standard.
