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 understand the content of dibutyl phthalate (DBP) in China’s major foodstuffs and to assess the level of DBP exposure and potential health risks of Chinese residents. Methods Based on the data of DBP content in 24 kinds of foods collected in 2011-2013 and the survey data of Chinese residents’ food consumption in 2002, the simple distribution assessment method was used to calculate the DBP dietary intake of Chinese residents and the effects of different foods on DBP intake Contribution rates, and compared with daily tolerable intake (TDI, 0.01 mg / kg BW) for risk characterization. Results The content of DBP in various foods ranged from 0.00 to 46.50 mg / kg with an average content of 0.11 mg / kg. The average dietary DBP intake of the whole population was 1.21 μg / kg BW, accounting for 12.08% of the total. The DBP intake of the whole population with high food consumption (P97.5) was 2.84 μg / kg BW, accounting for 28.42% of the TDI. The contribution rates of rice and instant noodles to DBP dietary intake were higher at 20.30% and 15.34% respectively. Conclusions Chinese residents have a lower health risk of dietary DBP intake and are at an acceptable level.
