A new method combining the scanning nuclear microprobe (SNM) with the pattern recognition of artificial neural network (ANN) was studied for the source identification and apportionment of aerosol particles. A technique of preparing of single aerosol particle sample was developed. A multi-station and multi-parameter data system for SNM was set up. A ANN program package was used for the source identification and apportionment of aerosol particles based on the Micro-PIXE spectra. The new method was preliminarily applied to the PM10 aerosol particles in the atmosphere of Shanghai city.
