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, only 2. 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 high consumer(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.
