The study includes the determination of the general background PCDD/F and dl-PCB levels in environmental (ambient air and soil) and food (meat, milk, egg, leafy vegetable, root vegetable and fruit samples) samples collected in four sampling sites in the vicinity of IZAYDAS WIP and its possible health risks. The local and meteorological conditions (prevailing wind direction, season, raining, and soil structure) were taken into account in the selection of sampling sites. The concentrations of PCDD/F and dl-PCB in ambient air ranged from 0.00841 to 0.05881 pg I-TEQ/m

. These results are quite low and it showed that there is no significant PCDD/F pollution in the vicinity of the plant. The results of PCDD/F and dl-PCB in eight soil samples (four in the range of 0–1.2 km, four in the range of 1.2–5 km) taken from the vicinity of IZAYDAS varied between 0.12681 and 0.4353 pg TEQ/g. The levels of PCDD/F and dl-PCBs measured in food samples were found to be significantly lower than both the limit values given by the Turkish Food Codex and the levels measured in the previous studies (between 2008 and 2009). In the health risk assessment, carcinogenic risk was calculated for PCDD/F and dl-PCBs made according to the exposure scenarios established for the study. The total intake values for the sum of PCDD/F and dl-PCB were found between 0.08 and 0.37 pg TEQ/kg.day for adults. These values are well below the limit value, which is considered as 2 pg WHO-TEQ/kg body weight.day. In this context, it was concluded that carcinogenic risk due to PCDD/F and dl-PCB intake is significantly low in the vicinity of the plant.
