摘要：

To identify the origin of PM10 (particulate matter with aerodynamic diameter equal to or less than 10 mum) in the atmosphere of Shanghai City, single PM10 particles from two environmental monitor locations and six pollution emitter sources were measured by scanning nuclear microprobe techniques. Every PM10 particle is characterized by its,micro-PIXE spectrum. The strategy of micro-PIXE spectra combined with the pattern recognition technique is applied to identify original sources of measured PM10 particles. The results of this investigation show that the most of the measured PM10 particles are derived from building construction sites, cement factories, vehicle exhaust, coal boilers and steel mills.
