title: [Comparison of two methods in calculating the cumulative cadmium intake (CCI) from rice in the cadmium polluted area].
abstract: OBJECTIVE
  To explore a more accurate method for calculating the cumulative cadmium intake from rice.
  
  
  METHODS
  The cumulative cadmium intake from rice was calculated by using the age coefficient method and the curve equation of rice consumption, and the results were compared.
  
  
  RESULTS
  There was little difference between the two results in male and female group. But the equation calculation values was more closer to the actual values and it was similar between different gender. But the result calculated by the age coefficient method between different gender was significantly different.
  
  
  CONCLUSIONS
  In the area that rice is the main medium of dietary cadmium intake, there was little difference between the two methods. Using curve equation of rice consumption to calculate the cumulative cadmium intake from rice is more feasible.
