13/05/2002  The concentration and amount of Se‐enriched fertiliser can be varied to achieve an optimum concentration of Se in rice products. The authors suggest that these Se‐enriched rice products can contribute an increase in Se intake of 50–100 µg day −1 on average if their Se concentration is controlled in the region of 0.15–0.50 µg g −1 .

01/06/2002  Atomic fluorescence spectrophotometry was used to determine the selenium (Se) concentration in 30 rice products of different species from Southern China. The Se level ranged from 0.015 to 0.046 µg g−1. Considering the average daily individual consumption of rice products in Southern China, the average dietary intake of Se supplied by this source is only 6–18 µg day−1 for an adult.
