Arsenic concentration of food from Guangzhou city in China was determined by hydride generation atomic fluorescent spectrometry. A wide range of arsenic concentration (0.0178 - 0.2226 mgkg-1) was found among the various food. The arsenic concentration of animal foods was obvious higher than that of plant foods, particularly organ meat, aquatic productions, rice and pork were main resources of arsenic. The obvious different daily arsenic dietary intake in different residents was reported: high income groups (95.39 µgd-1)>middle income groups (90.53 µgd-1) > low income groups (86.62 µgd-1), the daily arsenic dietary intake of the elder was 59.70 µgd-1, the child was 40.23 ugd"1, university man was 96.30 µgd-1, the worker was 89.05 µgd-1, the standard man was 94.46 µgd-1. Rice, vegetable and animal foods were the major contributor to dietary intake. The daily arsenic dietary intake of resident was safety in Guangzhou. [ABSTRACT FROM AUTHOR]
