Özet
The Gediz River is of great importance for agriculture in the region as well as its delta being an extensive wetland, qualified as an Important Bird Area by the WWF. Besides this, the delta has been protected as a Ramsar site since 1998. On the other hand it has been reported that the river is heavily polluted by agricultural, domestic and industrial discharges. In this preliminary investigation the deposition of some heavy metals (As, Pb, Cd, Ni, Cu, Co and Cr) in sediments of the delta was analyzed to estimate the effect of pollution. According to the results, it can be concluded that there is no pollution risk for As, Cu, Cd, Co, Ni and Pb. However, a high Cr content (2565.5 ppm maximum) was detected especially at station 2 and 3, where the wastewater of the leather industry was discharged into the channel connected to station 2, even though the plant has a treatment system.
