TL;DR: No effect of exercise was found on muscle or liver enzymes, although exercise resulted in depressed glutathione reductase (GR) and glucose-6-phosphate dehydrogenase (G6PD) activities in erythrocytes immediately after exercise.
Abstract: Experiments were conducted to determine the effects of exercise on rat glutathione peroxidase system enzymes and lipid peroxidation among animals supplemented and unsupplemented with selenium (Se) and vitamin E (E). Liver, muscle and blood were taken before, immediately after and 24 hours after exercising to exhaustion by swimming. No effect of exercise was found on muscle or liver enzymes, although exercise resulted in depressed glutathione reductase (GR) and glucose-6-phosphate dehydrogenase (G6PD) activities in erythrocytes immediately after exercise. Dietary Se supplementation did result in increased hepatic muscle and erythrocyte glutathione peroxidase activity, and decreased hepatic GR, G6PD and "malic enzyme" activities. Thiobarbituric acid reactive substances, and indicator of lipid peroxidation, increased in liver and muscle subsequent to exercise. This increase was reduced in liver, but not eliminated, by dietary E supplementation. The increase was not affected by dietary E in muscle, nor by dietary Se in either tissue.

TL;DR: In this paper, MGO composites have favorable removal capability of both selenite and selenate in water with important potential practical applications in removing selenium from wastewater.

TL;DR: The geochemistry of selenium is largely controlled by that of iron, with which Se is closely affiliated in both oxidizing and reducing environments as mentioned in this paper, and Se oxyanions, HSeO−3 and SeO2−3, are strongly adsorbed by hydrated surfaces of ferric oxides over the pH range 2-8; above pH8 adsorption decreases to complete desorption at pH 11.
