青岛市售畜禽肉类中邻苯二甲酸酯的检测与健康风险评估

Detection and risk assessment of phthalic acid esters in marketed livestock and poultry meat in Qingdao

以青岛市售的畜禽肉类农产品为研究对象，采用超声萃取-气相色谱法测定了畜禽生肉和熟肉样品中6种邻苯二甲酸酯（PAEs）的含量，采用非化学致癌物风险评价模型进行了健康风险评估。结果表明，畜禽肉中PAEs检出率在10％～90％，畜禽肉中∑_6PAEs含量在2mg·kg-1以下的所占比例较高；生、熟肉中∑_6PAEs平均含量分别为1．44mg·kg-1和3．67mg·kg-1，不同种类的生肉中∑_6PAE8含量没有显著性差异，熟鱼肉和熟猪肉的含量较高；相同种类的生熟肉相比，熟肉中∑_6PAEs的含量高于生肉；不同种类畜禽肉中PAEs组成存在一定差异，总体上邻苯二甲酸二（2-乙基己基）酯（DEHP）、邻苯二甲酸二甲酯（DMP）和邻苯二甲酸二正辛酯（DNOP）所占比例较高；畜肉和鱼肉类的总风险高于禽肉类，风险主要来自于DEHP；相同种类的生肉和熟肉相比，熟肉中PAEs风险明显高于生肉，但总体上青岛市售畜禽肉类中PAEs的健康风险未超出国际推荐的标准，无健康风险。

The contents of 6 kinds of phthalic acid esters（PAEs） in marketed livestock and poultry meat in Qingdao were detected with ultrasonic solvent extraction and gas chromatography. Health risk assessment for PAEs in livestock and poultry meat was made by non-chemical carcinogen health risk assessment model. Results showed that the detection rate of PAEs in livestock and poultry meat was in the range of 10%~90% and the ratio of the total of PAEs（∑_6PAEs） contents below 2mg·kg-1 was high. The average content of ∑_6PAEs in raw meat and cooked meat was 1.44mg·kg-1 and 3.67mg· kg-1, respectively. There was no significant difference in ∑_6PAEs content between different types of raw meat,and ∑_6PAEs was higher in fish and pork meat among cooked meat. The PAEs composition in types of livestock and poultry meat was different,and in general,the ratio of di （2-ethylhexyl） phthalate （DEHP）, dimethyl phthalate （DMP） and di- n-octyl phthalate （DnOP） was high. The risk value of PAEs in livestock and fish meat was higher than that in poultry meat,mainly coming from DEHP. Compared with raw meat,the risk value of PAEs in cooked meat was higher. However,the health risk assessment value of PAEs in marketed livestock and poultry meat in Qingdao was below the international recommended standards, indicating no health risk.
