Investigation of PCB ve PAHsin Soil: Alikahya Region

Abstract

In this study, Polychlorinated Biphenyls (PCBs) andPolycyclic Aromatic Hydrocarbons (PAHs) were investigated in the soil samples taken from Alikahya, Kocaeli. For this purpose, Sampling was conducted in a circular area with a Radius of approximately 2,5 km at six points of which coordinates are determined before. There are residential places, industrial facilities, TEM highway, E-5 motorway and a waste incineration plant around the area. The soil samples were collected from north, south, east and west side of a waste incineration plant. Samples were taken from 5 to 30 cm depth within 1,25 km and 2,5 km Radius of incineration plant. PCB and PAH concentrations in the soil samples were determined by Gas Chromatography/Mass Spectrometry (GC/MS). The determined concentrations of these pollutants in the soil were compared with the limit values of Turkish Soil Contaminated Sites on Point Source Pollution Control and Regulation. Among the PCB derivatives, whose concentration shave exceeded the limit values of the regulation, were measured at North and east direction. Among PAH derivatives, concentrations of Benzo(a)anthracene and Benzo(a)pyrenemeasured at all directions, Benzo(k)flouranthene and Benzo(b)flouranthene measured at North and west and east directions, Dibenzo(a.h)anthracene measured at North and west directions and Indene(1,2,3-cd)pyrene measured at west directions are above the limit values.
