摘　　要：为了解空气中铅的来源,用质子微探针测量了上海市吴淞地区空气PM10环境监测样品,用微束质子激发单颗粒X射线能谱“指纹结合模式识别技术研究了该地区铅污染的来源.结果表明,该地区含铅颗粒物主要来源于钢铁工业(48%)、汽车尾气(25%)和土壤尘(7%).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%).
