Abstract
OBJECTIVE: To estimate the dietary cadium intakes by different age-sex groups in China. METHODS: The cadium concentrations of food sample from 3rd Chinese total diet study were determined, and then combine these data with the food consumption by population of ten age-sex groups, The cadium intakes, and its distribution and dietary sources were obtained. RESULTS: It was found that the mean and median concentrations of cadium in all food samples were 0.046 and 0.006 mg/kg, respectively. The cadium contents in shellfish and liver were far higher than other food staffs. The cadium intakes by different age-sex groups were estimated to be 12.0 - 25.9 microg/day, ranged from 30.3% to 67.0% of PTWI. The individual dietary cadium intakes by 14% children in 2 - 7 years old group exceed PTWI. Cereals, vegetables and seafood were the main sources of cadium exposure, and contributed about 80% of total intakes. CONCLUSION: Although the dietary cadium intakes by different age-sex groups are all lower than PTWI, they are increased in the past decade. Moreover, in some provinces, the cadium burden of people is heavy.
