Abstract: Proton induced X-ray emission (PIXE) has been used to measure trace elements in sediments of Orontes River. Measurements were carried out using a 2MeV proton beam produced from of the 3MV tandem accelerator. Sediment samples were collected from 11 sites covering the important potential pollution sources at the river. The accuracy of the experimental procedure was verified using a certified sediment reference material (IAEA-SL1) and was found to be less than 10%. The results have shown that Pb and As were within the natural levels. In contrast, high concentrations of other elements like Cr, Cu, Ni and Zn have been found at different sites and explained by local human and industrial activities. [Copyright &y& Elsevier]
