Abstract Concentration factors (CF) of 54Mn for three aquatic species: green algae (Protococcoidal chlorella), Daphnia magna, and fathead minnows (Pimephales promelas) were determined following direct exposure to the isotope in solution. The maximum accumulation (CF = 911) in P. chlorella was reached at 48 hours of exposure; the maximum uptake (CF = 65) in Daphnia was reached at 8 hours of exposure; and the maximum accumulation (CF = 22.6) in fathead minnows was at 128 hours of exposure. The data indicate that 54Mn accumulation decreases with ascent up a theoretical aquatic food chain when water is the only source of contamination.
