Under natural conditions fish concentrate selenium (Se) in visceral tissues, attaining concentration factors (tissue Se/water Se) of 590-35,000. Food chain bioaccumulation is an important route of Se exposure for fishes, and organic forms may be more readily concentrated than inorganic forms. Fish concentrate Se in liver, kidney, and heart under laboratory conditions. High Se concentrations in bluegills (Lepomis macrochirus) are associated with decreased reproduction in Se-enriched reservoirs, and Se appears to concentrate in the ovaries of these fish. Furthermore, Se may be a teratogenic agent causing abnormalities in bluegill larvae, and high Se concentrations in the ovaries of female bluegills may be responsible for these abnormalities. Therefore, the authors proposed to compare the accumulation of (75) Se in gonads with its accumulation in other tissues and organs to assess the deposition of Se in bluegills.
