Abstract:

The city of Karsak Deresi, which is located within the border of the island of Bursa and between the Isnik Lake and Gemlik Bay, is the most water-transporting stream of the Gemlik district. The Karsak Deresi, which provides the discharge of the İznik Lake, is exposed to the sources of pollution in the İznik Lake and its pool and is thrown into the Gemlik Bay with many contaminants in its content. In addition to the fossil waters of the southern part of Orhangazi as well as the waste waters of industrial organizations and private companies in the region are transferred through the Karsak Deresi to the Gemlik Bay and significantly create a problem of pollution. In this study, data from seasonal water samples from 10 different points selected in the Karsak Deresi for pollution monitoring in 2013 and 2014 were examined. The seasonal average of parameters such as pH, temperature, dissolved oxygen, chemical oxygen need, ammoniac nitrate, nitrate nitrate, nitrate nitrate, aluminum, baker, iron, manganese, nickel, zinc, bor, balloon and chromium analyzed in the examples, the water pollution control regulation (SKKY) has been tried to identify the potential of pollution transferred to the Gulf by assessing according to the quality criteria according to the Classes of Inland Water Resources (SKKY).
