Pollution Situation and Health Risk Assessment of Polycyclic Aromatic Hydrocarbons in Barbecue

The content of 15 kinds of PAHs in 45 batches of barbecue was determined by HPLC method,the composition characteristics and toxicity distribution of PAHs in barbecue were analyzed,and the risk of eating barbecue frequency for lifelong cancer in social population was evaluated quantitatively. The results showed that,the composition characteristics and toxicity distribution of 15 kinds of PAHs in barbecue were indicated,the PAHs content was mainly two ring,three ring and four-ring aromatic hydrocarbons(87%),while in toxicity distribution,the main carcinogenic risk substances were heavy PAHs,with the highest toxicity content of PAHs in five rings(81%). Health risk assessment showed that there was a proportional relationship between the risk of cancer(ILCR)and the intake of barbecue frequency(EF)in the social population(ILCR=3.07692×10^-7 EF),high and frequent intake of barbecue would bring a certain risk of cancer,and low frequency intake of barbecue foods,such as three to four times a year,barbecue food caused by the risk of cancer could be ignored.
