Özet

Suspended sediment particles collected from 33 sampling points at a site located close to industrial and geological areas in Gediz river, western Turkey were analysed for 15 elements (Ca, Ti, Mn, Zn, Rb, Sr, Y, Zr, Ba, La, Ce, Ra, U, Th and K-40) by Energy Dispersive X-ray Fluorescence Spectroscopy (XRF), Gamma Spectroscopy (GS), and Collector Chamber Method (CCM). Both varimax and oblimin factor rotations were applied to the data, but varimax rotated factor analysis was used for source identification of suspended sediments. Three factors were extracted from the suspended data, which account for about 70% of the total data variance. These factors are interpreted as economy, mine and radioactivity/mine/agriculture.
