This investigation surveyed Cadmium (Cd) content of Iranian
rice (oryza saliva) which is predominant rice culture
in north of Iran. A total of 60 samples were collected from
Ghaemshahr region in Mazandaran province (North of Iran).
The samples were collected in during harvesting of rice in
field. The first step, grains of raw rice were digested by
acid digestion method and then were analyzed for Cadmium by
atomic absorption spectrometer. To assess the daily intake
of Cd by rice, from daily consumption of rice was
calculated. The results showed that average concentration of
Cd in rice was 0.40± 0.16µg/g dry wt and ranged from 0.12 to
0.83 µg/g dry wt. The Cd content in the rice samples was
found to be upper the FAO/WHO Guidelines. Also average
weekly intake of Cd from rice was 7.7μg/kg body weight/week
that it was approximately 10% more than to the maximum
weekly intake recommended by WHO/FAO.
Key words:
Rice, Cadmium, Iran, intake, Oryza Sativa. |
