From: Mercury and selenium in fish of Fountain Creek, Colorado (USA): possible sources and implications
Concentrations of selenium (µg/kg, ppb, ww) in ovarian, skin, muscle and livers of individual fish from 11 sites are shown. Noteworthy at site MC-1 there are data for a creek chub and white sucker and at site LF-4, data from a stone roller and a white sucker; all other data shown by the bars were single fish at each of the other sites. We did not find gravid fish at all sites
