In this study, the exposure to polychlorinated biphenyls (PCBs) through fish consumption was assessed in Türkiye. The concentrations of total 41 PCBs and six indicator (i6) PCBs ranged 4.5–45.7; 1.0–32.1 ngg−1 wet weight (ww) in 21 edible fish species supplied from Izmir markets in 2022 and i6 PCBs are less than the maximum value allowed by the EU and the Turkish Food Codex. Cultured seabass and sea bream have significantly higher PCB levels than wild-caught fish. The most prevalent PCB congeners in all samples were 6Cl PCBs, which were followed by 5Cl PCBs. High chlorinated congeners (chlorine > 5) accounted for 74–90% of the ∑PCBs. The majority of the total seven indicator (i7) PCBs accounted for PCB153 and 138. PCBs 206 and 209 were the most prevalent congeners among the total PCB levels in mussel samples. According to the United States of America’s Environmental Protection Agency’s (US EPA) recommended oral reference dose and the Agency for Toxic Substances and Disease Registry’s minimal risk level, consuming 20 g per day for a person of 21 fish species does not pose a health risk to human health. Based on 50th and 95th percentile PCBs concentrations, the hazard ratios for cancer were more than one, suggesting these PCB concentrations may cause a lifetime risk of cancer for consumers to more than one in a million.
