%X Single aerosol particles in Shanghai air in winter 2004 were analyzed by proton microprobe.The micro-PIXE coupled with a pattern recognition technique was applied to identify the sources of single lead-containing particles.Seven source types were identified.They were automobile exhaust,metallurgical industry,coal combustion,soil dust,diesel exhaust,motorcycle exhaust and cement dust.The lead pollution in Shanghai air was derived mainly from the metallurgical industry and coal combustion after phasing out leaded gasoline in 1997.
