Notes :    (1) Locations: Rosenthal and Stewart -- laboratory; Adams et al. -- White Oak Lake at Oak Ridge, Tennessee (USA)
    (2) Data from Rosenthal and Stewart are recalculated (original data in dpm/mL and dpm/g). All bound tritium data are on a dry weight basis.
    (3) R 1 and R 2 are the bioaccumulation factors obtained by dividing the numbers in the indicated columns (Roman numerals separated by the slash). Column V entries in parentheses are as originally reported by Adams et al., which correct for specimen density.
    (4) Data for Gambusia affinis are for the whole animal.
    (5) Food chain relations from Adam's et al. data are undetermined. None of the listed animals species is known to consume any of the listed plant species. Physa heterostropha , epiphytic on macrophytes, eats algae. Algae of genus Cladophora are not usually desirable food for invertebrates and fishes. Dragonflies ( i.e. , Plathemis lydia ), consume smaller invertebrates rather than plants.
    (6) References: adapted from Tables II and III ( Blaylock and Frank 1979), with recalculation of bioaccumulation factors. See note 3.
