Selenium was found in a high percentage of the urine specimens obtained from normal, healthy male adults who had no industrial or other obvious selenium exposure. This finding is in contrast to recent references on the subject. 2. The concentrations of selenium averaged from 4 to 5 γ per 100 cc. of urine, with a range of 0 to 15 γ. 3. The rate of urinary selenium excretion is relatively constant and is quite independent of the urinary volume, suggesting that selenium is treated by the kidney as a "non-threshold" substance similar to sulfates and creatinine. The mean rate was 2.2 γ per hour with relatively slight variability. 4. A dietary source of selenium was found in wheat products, with selenium values ranging from 26 to 39 γ per 100 grams dry weight, or 0.26 to 0.39 parts per million. 5. No harmful effects were observed which could be correlated with the absorption and excretion of such amounts of selenium as were demonstrated in this study.}, issn = {0022-3565}, URL = {https://jpet.aspetjournals.org/content/73/2/205}, eprint = {https://jpet.aspetjournals.org/content/73/2/205.full.pdf}, journal = {Journal of Pharmacology and Experimental Therapeutics} }
