RUTHERFORD BACKSCATTERING AND X-RAY-FLUORESCENCE ANALYSIS OF SEDIMENTS

Sediments from Algiers bay were analysed by means of x-ray fluorescenc e (XRF) and by Rutherford backscattering spectrometry (RES), The RES a nalysis allowed the determination of the matrix composition of the sed iments, which was used for the XRF analysis. Quantitative analyses wit h the XRF and RES systems were performed by using an x-ray tube and a 3.75 MV Van de Graaff accelerator, respectively. The results give info rmation about the concentration levels of Mn, Cu, Zn and Pb in the sup erficial sediments (fine fraction) in the coastal zone. (C) 1997 by Jo hn Wiley & Sons Ltd.
