| contents | Environmental applications of PIXE at the Institute of Physics, UNAM A. Mireles H. Zolezzi-Ruiz C. Solís E. Andrade Física, Astronomía y Matemáticas PIXE Mexico biomonitors Trace elements heavy metal pollution The particle induced X-ray emission technique (PIXE), developed by Johansson and colleagues in Lund, Sweden, in the 70s has been usedsince then in a high number of studies requiring detection and quantification of trace elements at high sensitivity (better than 1 mg/kg).PIXE is grouped among the nuclear analytical techniques because the samples are bombarded with particles (protons generally) acceleratedin an accelerator. When protons interact with matter an X-Ray spectrum is produced by the deexcitation of atoms in the sample. Fromthis spectrum the elements contained in the sample as well as their concentrations can be determined. In this work we describe the PIXEtechnique and several applications in the environmental field developed at the Institute of Physics of the National Autonomous University ofMexico (IFUNAM). These practical applications include field studies for analyses of suspended particles in air using tree leaves, irrigationwater quality based on heavy metal analyses, and analyses of trace elements in plants cultivated in waste water irrigated soil. 2007 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57066308 https://www.redalyc.org/journal/570/57066308/ https://www.redalyc.org/journal/570/57066308/html/ https://www.redalyc.org/journal/570/57066308/57066308.epub https://www.redalyc.org/journal/570/57066308/movil en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
