concentration selenium optimal - jasperwegman.nl
The objective is the determination of the conditions operating optimal to determine the concentration of the selenium dissolved in the human blood. An electroanalytical method has been developed for the determination of selenium in whole blood by differential pulse cathodic stripping voltammetry (DPASV) on a hanging mercury drop electrode (HMDE).
Optimal synthesis conditions and characterization …
Selenium nanoparticles (SeNPs) was synthesized by a simple, environmentally benign SeO 2-reduction process in Trichoderma sp. WL-Go culture broth and followed by filtration to obtain culture broth supernatant which was then characterized. The optimal conditions for the SeNPs synthesis were pH 8, inoculation time of SeO 2 at 24 h and SeO 2 concentration of 2 mM.

Selenium in biology - Wikipedia
In fish and other wildlife, low levels of selenium cause deficiency while high levels cause toxicity. For example, in salmon, the optimal concentration of selenium in the fish tissue (whole body) is about 1 microgram selenium per gram of tissue (dry weight).

Defining the Optimal Selenium Dose for Prostate …
21-12-2009 · Dogs with moderate selenium status had toenail selenium concentration in the range of .67–.92 ppm. The cut-point of .92 ppm (equivalent to 137 μg/L in plasma) was selected because it represents the toenail selenium concentration that is equivalent to one standard deviation above the mean plasma selenium level of U.S. men (Kafai and Ganji 2003).
Selenium - Wikipedia
In fish and other wildlife, selenium is necessary for life, but toxic in high doses. For salmon, the optimal concentration of selenium is about 1 microgram selenium per gram of whole body weight. Much below that level, young salmon die from deficiency; much above, they die from toxic excess.

SUBJECTS AND METHODS. A randomized, double-blind, placebo-controlled trial was undertaken by using a parallel design in adults (n = 119) with a suboptimal selenium status, defined as a low (<110 ng/mL) plasma selenium concentration.Apparently healthy volunteers aged 50–64 y from Norfolk, United Kingdom, were randomly assigned to 1 of 6 groups.
