Determination of Nitrite, Nitrate, Phosphate and Fluoride Quantities in Water and Sediment of Eğirdir Lake, Turkey

Abstract

In this study that was carried out between February 2011 and January 2012, sedimentation of nitrite (NO2-), nitrate (NO3-), phosphate (PO43-), fluoride(F-) in water and sediment samples of 4 different stations of Egirdir Lake and their seasonal changes were examined. During the study, ions in water and sediment that collected from 4 different stations and in seasonal periods were measured by Ion Chromatography (IC) device. Egirdir Lake’s water temprature was determined as 7.2-26.7 0C and pH range as 7.58-8.54. As a result of ion analysis of water nitrite and phosphate were not detected in any season. While fluoride was detected in all seasons and all stations, nitrate was measured in different seasons and stations. It was detected that the most accumulated anion in water was fluoride. According to our findings of sediment, nitrite was not detected in any season. While nitrate and fluoride were detected in all seasons and all stations, phosphate was measured in different seasons and stations. It was determined that the most accumulated anion in sediment was nitrate. Egirdir Lake water is ranking in I. quality water class in terms of studied parameters
