    Abstract:
    OBJECTIVE: To investigate the cadmium pollution and safety in dietary of students in Jinzhou, and to provide scientific basis for rational diet. METHODS: The twelve kinds of foods were collected randomly. The contents of cadmium were determined by graphite furnace atomic absorption spectrometry (GFAAS). The intake level of cadmium in diet was calculated and evaluated by comparing to provisional tolerable monthly intake (PTMI) recommended by WHO/FAO and assessed safety of cadmium intakes in diet of students. RESULTS: The contents of cadmium in aquatic products and meats were 0.131 and 0.109 mg/kg respectively. The main sauces of cadmium were aquatic products, meats, vegetables and cereals, they were 34.08%, 24.02%, 17.32% and 17.32% of daily cadmium intakes respectively. The average intake and median intake were lower than PTMI, but percentile 97.5 was 12.4% of PTMI. CONCLUSION: The intakes of cadmium in diet of students were relative safety, but eating to much was also dangerous, so necessary to reduce intake.
