中国居民邻苯二甲酸二异壬酯膳食摄入水平及其风险评估

Dietary intake and risk assessment of diisononyl phthalate( DINP)in Chinese population

目的掌握我国主要食品中的邻苯二甲酸二异壬酯（DINP）含量水平,评估我国居民DINP膳食摄入水平及其潜在健康风险。方法利用2011—2013年检测的25类食品的含量数据及2002年中国居民营养与健康状况调查数据,采用简单分布评估方法,对我国不同性别-年龄组人群DINP摄入水平及其潜在风险进行评估。结果各类食品DINP的平均含量为0.24 mg/kg,最大值为9.55 mg/kg。我国全人群膳食DINP的平均每日摄入量为4.39μg/kg BW,仅占TDI的2.93%。不同性别-年龄组人群以2-6岁儿童每日摄入量最高,平均为8.91μg/kg BW,占TDI的5.94%,其次为7-12岁年龄组儿童,平均为6.53μg/kg BW,占TDI的4.35%;全人群中高食物量消费人群的DINP每日摄入量（P97.5）为8.35μg/kg BW,占TDI的5.57%,各性别-年龄组人群高食物量消费人群的DINP每日摄入量范围为5.44-13.84μg/kg BW,均低于TDI。结论我国人群DINP膳食摄入的健康风险总体处于可接受水平,健康风险较低。

Objective To study DINP concentration level in the main food,evaluate DINP dietary intake level in Chinese population and its potential health risks. Methods Based on the deterministic assessment model,using concentration level of 25 kinds of food in 2011- 2013 and Chinese national nutrition and health survey data in 2002,to calculate dietary intake of DINP in Chinese population. Results The average DINP concentration level in 24 kinds of foods was 0. 24 mg / kg,and the maximum value was 9. 55 mg / kg. In whole population,average dietary intake of DINP was 4. 39 μg / kg bw per day,only2. 93% of TDI. The dietary intake of DINP in children aged 2 to 6 years old was highest,with an average of 8. 91 μg / kg bw per day,5. 94% of the TDI. The dietary intake of DINP in children aged 7 to 12 years old was lower than 2 to 6 years old children,with an average of 6. 53 μg / kg bw per day,4. 35% of TDI. The dietary intake of DINP in highconsumer（ P97. 5） in all population was 8. 35 μg / kg bw per day,5. 57% of the TDI. The range of dietary intake of DINP in high consumer（ P97. 5） in each group（ grouping by gender and age） was from 13. 84 to 5. 44 μg / kg bw per day,which were all lower than the TDI. Conclusion The dietary intake of DINP in different populations is considerably below the TDI and any health risk that would be expected to occur at this intake level is negligible.
