Abstract:
Objective To investigate the pollution levels of six indicator polychlorinated biphenyls (PCBs) in animal-derived foods in Hebei Province. Methods A total of 96 food samples (including beltfish, snakehead, egg, pork liver, pork and beef meat) were collected from Hebei Province in 2019. The contents of six indicator PCBs (PCB 28, PCB 52, PCB 101, PCB 138, PCB 153 and PCB180) in different food samples were determined using isotope dilution-high resolution gas chromatography-high resolution mass spectrometry (HRGC-HRMS). Results The contents of indicative PCBs in fish samples ranged from 0.12 to 0.32 ngg-1 fresh weight, while the content of PCBs in other samples ranged from 0.11 to 1.10 ng g-1 fat. PCB 138 and PCB 153 were the main compounds detected in fish samples, while PCB 28 and PCB 52 were the main compounds detected in other samples. The average estimated daily dietary intake of PCBs for residents in Hebei Province was 0.14 ng kg-1·bw-1·d-1, and the highest contribution rate was beltfish (61.52%). Conclusion The pollution levels of indicator PCBs in animal-derived foods in Hebei Province are relatively low, and the residents has lower health risks through dietary intake of indicator PCBs.
