Determination of some nutrients of Gediz River as monthly and seasonal

Phosphate, nitrate, nitrite and amonium concentrations are determined in the water samples from Gediz River that also flows from Manisa city centre especially five stations. It was proved by graphics that phosphate, nitrate, nitrite and amonium concentrations changed according to stations and months. Also, pH, heat, and dissolved oxygen parameters were measured. According to the analysis results, the phosphate concentrations 0,002-0,214 mg/L, were found between these amounts and at all stations, monthly average phosphate concentration, 0,058 mg/L, were found. The nitrate concentrations 0,028-34,315 mg/L, were found between these amounts and at all stations, monthly average nitrate concentration, 10,39 mg/L, were found. The nitrite concentrations 0,015-0,704 mg/L, were found between these amounts and at all stations, monthly average nitrite concentration 0,184 mg/L, were found. The amonium concentrations 0,044-3,610 mg/L, were found between these amounts and at all stations, monthly average amonium concentration, 1,378 mg/L, were found. The obtained values from this research were compared with the results of the other studies.
