Methods Total mercury in food were measured by automatic mercury analyzer. There was no need of wet digestion or complex pretreatments of sample, and automatic direct injection. A total of 775 samples of 9 categories were randomly collected from Lhasa, Nyingchi, Lhoka, Shigatse and Ngari Prefectures. The total mercury levels in these samples were detected and analyzed. Results The contamination level of total mercury in food was low, and the unqualification rate of total mercury was only 2.06%, mainly caused by mercury pollution incident, the rest of the food was accord with national standard. The potential health risk from mercury exposure was low. Conclusion The contamination levels of total mercury in common food of Tibet Autonomous Region are generally low. The total mercury level in most food is under the limit requirements of national standards. However, food safety supervision for imported food should be further strengthened.
