Spatial Variations of Polycyclic Aromatic Hydrocarbon (PAH) Concentrations in the ReceivingWater Environment: The Nilüfer Creek
Abstract :
The objective of this study was to identify the spatial variations in PAH concentrations in the surface water samples, to determine the distribution of PAH species and their possible sources in the Nilüfer Creek which is one of the most important water resources in Bursa. Surface water samples taken from 6 different locations on the Nilüfer Creek were ultrasonically extracted and PAH content of the samples were measured by using a gas chromatography- mass spectrometry (GC-MS). Spatial total 12 (Σ12) PAH concentration profiles were in the range of 334-840 ng/L. The highest Σ12 PAH levels was measured as 840 ng/L in the sampling point (N2) located after East Wastewater Treatment Plant discharge. Gümüştepe recreation area (N1) was in the second order with regards to PAH levels. It was observed that only 3- and 4-ring species existed in the samples. 5- and 6-ring species were not detected. 3 ring species (Phe, Ant) constitute 93% of the Σ12 PAH content, 4 ring species (Fl, Pyr, BaA and Chr) constitute 7%. The diagnostic ratios of PAH species suggested that the pollution in the Nilüfer Creek is mostly pyrolytic.
