摘　　要：目的检测武汉市动物性食品中双酚A(BPA)含量,调查当地居民膳食中动物性食品的结构,计算其双酚A的暴露量,评估当地居民经该途径暴露双酚A的健康风险。方法随机选取该市常见的13种动物性食品,共78份。用液质检测仪检测样品中的BPA含量。随机选取本市180户居民,共计338人作为膳食调查对象,采用3 d24 h膳食调查法,统计其动物性食品的人均摄入量。结合当前BPA的参考剂量评估经该途径暴露BPA的风险水平。结果 BPA在动物性食品中检出范围为0.0～11.7 ng/g。该市居民人均动物性食品的摄入量为277.48 g/d,日均暴露水平(ADI)为11.38 ng/kg bw/day,远低于国际参考标准。结论 BPA在武汉市场上所售的大多数动物性食品中均有微量检出,但经动物性食品暴露的BPA水平,尚不会对居民的健康产生不利影响。Objective To determine the level of bisphenol A （BPA） in animal source foods in Wuhan urban area,investigate dietary pattern,calculate the BPA exposure level via animal source foods, and assess the health risk of exposure to BPA from animal source foods among local residents. Methods 78 samples containing 13 kinds of animal food were ran- domly selected, and the concentration of BPA was determined by LC-MS. 338 people from 180 families were randomly cho- sen. What they ate in recent three days was reviewed, and the amount of animal source foods intake per capita was analyzed. The average BPA exposure was assessed through the concentration of BPA in the investigated samples and dietary data, and the BPA exposure risk level of the local residents were assessed via animal source foods intake. Results the concentration of BPA in animal source foods was between 0. 0 to 11.7 ng/g. The intake of animal source foods was 277.48 g.d-1 per capita in dietary survey data analysis. The average daily intake （ADI） of BPA was 11.38 ng/kg bw/day, which was obviously lower than the international limited dose （50 μg/kg/d）. Conclusions Only micro-amount BPA in the majority of animal source foods in Wuhan could be detected,therefore,this would not affect adversely to the health of the local residents.
