摘要：

The Van de Graaff Facility at IHEP is mainly used for PIXE research work especially on biologicial and environmental science. The sensitivities and the number of analyzed trace elements were improved greatly using special absorbers for bone and whole blood samples. Quite good results were obtained for different biomedical research work. Several methods for preparing samples of dispersed single aerosol particles used in Scanning Proton Microprobe (SPM) analysis were tested. The groups of different single aerosol particles from steel plant area were analyzed by means of SPM. The distributions of elemental contents in the group of single particles are mapped with three dimensional contour and the isometric. A new approach to study the group of different single aerosol particles for air pollution is developed in the present work.
