Abstract: The total selenium and aqueous and exchangeable selenium was fluorometrically determined in two samples of crude rice;one had been fertilized with selenium and the other had not.The results showed that the selenium level of the former sample(total selenium is 0.075×10-6;aqueous and exchangeable selenium is 0.020×10-6 was higher than that of the latter(total selenium is 0.045×10-6; aqueous and exchangeable selenium is 0.010×10-6.

Key words: total selenium, aqueous and exchangeable selenium, crude rice, fluorescence method
