Selenium concentrations in the liver, kidneys, and muscles in silver foxes (Vulpes vulpes).

Selenium concentrations in the liver, kidneys, and muscles of silver foxes living at a farm in West Pomerania, (northwestern Poland) were determined. The studies were performed on 243 tissue samples collected from 81 foxes. Selenium concentration was determined using the modified Watkinson’s spectrofluorometric method. The highest Se concentration was found in the kidneys, with a mean level of 0.587 µg/g of wet weight. In the liver, the mean level was 0.247 µg/g w.w. and in muscles 0.070 µg/g w.w.
