Wąsowicz, W: Selenium concentration in human urine. Acta physiol, pol., 1989, 40 (5-6): 558-563. In this work we have determined selenium concentration in urine in two groups of healthy subjects. Selenium content in the younger group, aged 11-15 years (n = 41), was 13.7 ± 6.5 µɡ/ɡ⁻¹ creatinine. In the older group, aged 17-97 years (n = 62), slighty but statistically significant lower selenium concentration in urine (11.4 ± 4.9 µɡ/ɡ Ct, p<0.05) was found. We have also shown a significant difference in the excretion of the element between the group of boys and men (p < 0.05). Concentration of selenium excreted in urine in tiie population of healthy people (11-97 years, n = 103) is 12.3 ± 5.4 µɡ Se/ɡ Ct.
