Abstract： Objective： To establish a method for the determination of polycyclic aromatic hydrocarbons content in barbecued foods by high performance liquid chromatography-fluorescence detection （HPLC-FLR） investigate the residue situation of polycyclic aromatic hydrocarbons in barbecue foods in Chaoyang city，Liaoning province. Method： Atotal of60 samples of barbecue food from mobile stals，outdoor self-griledand fixedbarbecue restaurants in Chaoyang city were colected.The contents of 15 kinds of polycyclic aromatic hydrocarbons were detected by HPLC-FLR method. Result： The linear relationship of 15 kinds of polycyclic aromatic hydrocarbons was good within 1ng⋅mL-1 to 100ng⋅mL-1 ，the correlation coefficient r was greater than O.999，and the recovery rate met the analytical requirements.The overall detection situation of15 kinds of polycyclic aromatic hydrocarbons in barbecue foods in Chaoyang city is not optimistic.Some of them exceeded the limits in the GB 2762—2022 and the European Union standard. Conclusion： The residues of polycyclic aromatic hydrocarbons in barbecued foods are serious.Relevant departments should formulate corresponding barbecue norms and strengthen the monitoring of outdoor barbecues.
