THE POTENTIAL SOURCES OF POLLUTION AFFECTING THE WATER QUALITY OF LAKE IZNIK

摘要

This study aimed to examine Lake Iznik, one of the most significant water resources of the SouthMarmara Region, and the anthropogenic pollution types affecting the drainage basin and their possible effects.Lake Iznik, a water resource that is quite significant because of its geographical position, is polluted not only withthe point and non-point sources of pollution around it, but also with the pollutants spread via highways which arelinear pollutants. The fertilization and disinfection of agricultural lands are considered to be one of the mostsignificant factors changing the trophic level of the lake. Biological diversity of the lake is examined in manystudies, while the studies on water quality are limited. The decrease in the type and amount of the productions ofthe lake indicates to the increasing destruction of the ecological balance as a result of the water pollution.
