Abstract: Selenium contents in various fruits from the Guangzhou city, Guangdong province, were determined after acid digestion by hydride generation atomic fluorescent spectrometry. All fruits were sampled from supermarkets and terminal markets. Accuracy was assured with standard reference material (GBW08551) and recovery rate in experiments. A wide range of selenium content (1.09～13.3μg/kg) is found among the various fruits, and the mean selenium content in fruit is 4.97μg/kg. The selenium content of various fruit groups is in the order: tropic fruit (6.03±2.59μg/kg)>berry (5.53±0.87μg/kg)>kernal fruit (5.18±0.33μg/kg)>drupe fruit (4.78±0.97μg/kg)>orange fruit (3.92±0.50μg/kg)>melons (3.43±0.94μg/kg).
