[Investigation of dietary intake of cadmium in certain polluted area of south in China].
OBJECTIVE
To investigate the situation of dietary intake of cadmium and provide evidence for Cd pollution prevention and control in the south area in China.


METHODS
Three types of local food sample, including cereals, vegetables, meat and eggs, were collected and detected for cadmium content. Dietary survey was carried out in the local resident in the same time.


RESULTS
140 food samples were collected from 54 households. 71.69% of rice were above the limitation of the cadmium content according the national standard. Dietary survey conducted in 262 residents showed that the main food was rice. Thus, cadmium intake from the rice was one of the major dietary sources in this area, and cadmium intake from rice was different from the age group. The average cadmium intake for one's lifetime was at least 4 g in this area.


CONCLUSIONS
Cadmium pollution prevention and control should be focused on the food chain from crops to the human being in this contaminated area.
