Description
Due to their lentic and enclosed nature, lakes are more susceptible to organic pollution and eutrophication. İznik Lake, which is an ideal place for various recreational activities such as fishing, swimming and water sports, is the largest natural stagnant water ecosystem in the Marmara Region and has a rich biodiversity. Despite its natural beauty and importances, İznik Lake is exposed to organic pollution from surrounding agricultural activities, industrial discharges, domestic wastewater, and agricultural chemicals. This study evaluated and compared the eutrophication threat for the west (WC) and east (EC) coasts of the İznik Lake by means of some modified biodegradable contamination indices (MBCI) using Turkish Standards. For this purpose, nutrient pollution index (NPI), organic pollution index (OPI) and eutrophication index (EI) were selected as the organic pollution risk assessment indicators. Water samples were collected in the winter season of 2025 and measured for 4 limnological parameters (DO, COD, NO2-N and PO4-P) that are used to calculate the MBCIs. The results revealed that although the WC exhibits a lower potential eutrophication risk compared to EC, the water of both WC and EC were highly polluted and had an eutrophic character.
