| Abstract: | In order to understand the origin of lead in air, proton microprobe was used to measure PM10 environmental monitoring samples of Wusong district, Shanghai City, and lead pollution origin of this district was studied with micro-PIXE spectrum fingerprint combined with pattern recognition technique. The main origins of the leadcontaining particles were metallurgic industry (48%), vehicle exhaust (25%) and soil dust (7%). |
