Title: Health risk assessment of polychlorinated biphenyls (PCBs) in urban soils of Sofia
Keywords: Dioxin-like polychlorinated biphenyls (dl-PCBs);

Abstract: There is a lack of information regarding levels of polychlorinated biphenyls (PCBs) in soil samples from Bulgaria. This paper reports the concentrations of six indicator PCBs and six dioxin-like PCBs determined in 35 soil samples from urban areas of Sofia City, the capital of Bulgaria. TEQ values of dioxin-like PCBs were calculated also. The results show that the sums of concentration of indicator-PCBs were in the range 7.2-17.2 μg/kg. Small amounts of all dioxin-like PCBs also were found (1.1-5.1 μg/kg). High chlorinated indicator-PCBs: 138, 153 and 180 were the most abundant in the soil samples. Dioxin-like PCB 77 was in minor concentration (0.25 μg/kg) and dl-PCB 118 was predominant dioxin-like congener (0.68 μg/kg). TEQs of soil samples are in the range 0.006-0.08 μg/kg. The highest TEQ is found for PCB 126. All concentrations of PCBs determined in this study are below the maximum admissible concentration in soils according to the Bulgarian Legislation and TEQ concentrations met t
