Özet

Polycyclic aromatic hydrocarbons (PAHs) contain two or more benzene rings and are categorized as general environmentally harmful pollutants. PAHs occur because of various combustion and pyrolysis processes with different environmental and anthropogenic sources. The Kizilirmak River is one of the major important water sources used for drinking water and irrigation purposes in Turkey. There are important industrial facilities around the river and PAH pollution is important in terms of environmental health. This study was carried out to determine the residues of PAHs in water and sediment samples according to month and to identify the pollution sources. Thus, water and sediment samples were collected from five different stations in the Kirikkale basin of the Kizilirmak River every 15 days for a year. In this way, 120 water and 120 sediment samples were collected over a year and analyzed in terms of 16 priority PAHs according to the Environmental Protection Agency. The monthly average of the water and sediment samples was calculated. Analyses were carried out with high-performance liquid chromatography based on solid phase extraction. GC-MS was used for confirmation. Acenaphthene, acenaphthylene, benzo [b] fluoranthene, benzo[a]pyrene, indeno[l ,2,3-cd]pyrene, and dibenzo[a,h]anthracene were not found in the water samples. The total PAH levels in water and sediment were detected in the range of 0.04 to 1.545 mu g/L and 43.15-386.115 mu g/kg, respectively. PAHs found in water and sediment samples had pyrogenic and petrogenic origin and pollution changed significantly between autumn and winter. As a result, precautions should be taken in terms of preventing environmental pollution.
