Description

İznik Lake, located in the Marmara Region of Türkiye, holds significant ecological, historical, and socio-economic importance. Therefore, preservation of İznik Lake is vital for maintaining ecological balance, cultural heritage, and economic stability in the region. Despite the mentioned importances, İznik Lake is subject to significant pollution from surrounding anthropogenic activities. This study undertook a comparative hydrochemical assessment of the water quality in the west (WC-İL) and east (EC-İL) coasts of İznik Lake. During the winter season of 2025, water samples were collected and analyzed for 11 limnological parameters: Electrical Conductivity (EC), Total Dissolved Solids (TDS), salinity, Dissolved Oxygen (DO), O2 saturation, pH, turbidity, Suspended Solids (SS), nitrite nitrogen (NO2-N), orthophosphate phosphorus (PO4-P), and Chemical Oxygen Demand (COD). The findings indicated that the water of WC-İL exhibited a more alkaline character than EC-İL. Although the salinity parameter data of coasts were quite close to each other, the organic pollution parameter data were much higher in EC-İL than in WC-İL. Also, NO2-N and PO4-P values in water of EC-İL were 1.5 – 2 times higher than in water of WC-İL, respectively.
