Abstract
In order to make a tentative recommendation for the maximum acceptable daily intake of selenium, relevant data were compiled from the available literature. Normal daily intake of selenium from foods was estimated as about 100 mug, half of which comes from fish and shellfish (in an average adult Japanese). Intake of selenium from other sources was negligible. The amount of selenium excreted in the urine was found to be compatible with the estimated value of the daily oral intake. The range of the margin of safety was then estimated as 10 to 200 times the normal level on the basis of human and animal toxicity data. The variation of dietary selenium intake in the general population is discussed, leading to the conclusion that the consumers of large amounts of fish may ingest as much as 500 mug daily. Consequently, a value of 500 mug is proposed as the tentative maximum acceptable daily intake of selenium for the protection of human health.
