title: [Dietary intake and risk assessment of diisononyl phthalate (DINP) in Chinese population].
abstract: 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.
  
  
  CONCLUSIONS
  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.
