Gediz Nehri Aşağı Gediz Havzası`ndan Alınan Su ve Sediment Örneklerinde Bazı Kirlilik Parametrelerinin İncelenmesi

Abstract

The River Gediz, is the second greatest river of Aegean Region, is under threat o f pollution caused by institutions o f region, domestic waste, agricultural chemicals and artificial fertilizers. All kinds o f substances which are above standardized limit values for water can make pollution. These pollutant levels could determine water usage aims. Heavy metals in trace level are the most hazardous o f these matters. In our study, the physical and chemical parameters o f water and the level o f heavy metal concentration in water and sediment samples are analyzed in five different stations o f Gediz River. The average level of some parameters are; BOD: 67.7 mg/L, COD: 88.7 mg/L, pH: 7.6, turbidity: 440 mg/L SiO2 . In water samples, the metals in high level are; Pb: 27.0±%0.8 ug/L at N if River, Cr: 48.9±%0.9 ug/L at Muradiye Bridge, Cd: 12.1±%0.6 |Ug/L at Istanbul Bridge, Cu: 90.2±%0.4 ug/L at Muradiye Bridge, Ni: 309.8±%0.7 ug/L, Fe: 914.1±%0.3 /Ug/L, Zn: 208.3±%0.5 ug/L in Karagay The quality of water is at the level of four, according to Water Pollution Control Regulations. The sediment and soil samples taken from different station were also compared. It is seen that, the organic matter which is accumulated at the bottom o f the river, increase the concentration of the metals.
