The largest mean concentrations were <br />in kidney tissues, followed by livers, eggs, axial muscle tissues, and stomach <br />tissues (fig. 17). Sager and Cofield (1984) reported a similar pattern of <br />selenium concentrations in four fish species; in order of decreasing selenium <br />concentrations, these were: liver, female reproductive tissue, axial muscles, <br />and male reproductive tissue. <br /> <br />Aquatic invertebrate samples from Sweitzer Lake had selenium concentra- <br />tions of 26.7 and 29.8 ~g/g dry weight. The algae sample collected from <br />Sweitzer Lake had a selenium concentration of 12.8 ~g/g dry weight (table 23), <br />which is in the range of concentrations reported for algae collected at <br /> <br />53 <br />
