摘　　要：目的了解我国主要食品中邻苯二甲酸二丁酯（DBP）的含量,评估我国居民经膳食暴露于DBP的水平以及潜在的健康风险。方法利用2011—2013年收集的24类食品中的DBP含量数据以及2002年中国居民食物消费量调查数据,采用简单分布评估方法,计算我国居民DBP膳食摄入水平,以及不同食物对DBP摄入的贡献率,并与每日可耐受摄入量（TDI,0.01 mg/kg BW）比较,进行风险特征描述。结果各种食品中DBP的含量范围为0.00-46.50 mg/kg,平均含量为0.11 mg/kg,全人群的膳食DBP平均摄入量为1.21μg/kg BW,占TDI的12.08%。全人群高食物消费量人群（P97.5）的DBP摄入量为2.84μg/kg BW,占TDI的28.42%。大米、方便面对DBP膳食摄入的贡献率较高,分别为20.30%和15.34%。结论中国居民膳食DBP摄入的健康风险较低,处于可接受水平。Objective To investigate dibutyl phthalate（ DBP） concentration level in food,assess the dietary exposure of DBP among Chinese population and its potential health risks. Methods Using simple distribution method to estimate DBP dietary exposure in Chinese population,DBP concentration level of 24 food categories was collected during 2011 to2013 and the consumption data were taken from China National Nutrition and Health Survey in 2002. Subsequently,the risk was characterized by calculating the exposure and comparing with the tolerable daily intake（ TDI,0. 01 mg / kg BW） of DBP. Results DBP concentration level in foods was in the range of not detected to 46. 50 mg / kg,and the mean was 0. 11 mg / kg. The mean dietary intake of DBP in general population was 1. 21 μg / kg BW,accounting for 12. 08% of TDI. The dietary intake of DBP high-consuming populations was 2. 84 μg / kg BW,accounting for 28. 42% of TDI. The major food contributors to DBP were rice（ 20. 30%） and instant noodles（ 15. 34%） for the general population. Conclusion This results suggested that the DBP exposure in Chinese population was considerably lower than the TDI and the health risk caused by DBP at this intake level was quite low.
