Steller sea lion (Eumetopias jubatus) tissue mercury concentrations increasingly above thresholds of concern occur in regions of Alaska where lack of population recovery is noted. Selenium–monomethylmercury interactions may mitigate toxicosis but may also result in functional selenium deficiency, im...
