Duplicated flow-through exposure systems consisting of two diluters, operated simultaneously, were used to compare the bioconcentration of (14)C-di-n-hexylphthalate ((14)C-DHP) by Daphnia magna under single-species (modular) or multispecies (mixed) model formats proposed for use as microcosms to estimate bioconcentration. Triplicate exposures of Daphnia in each diluter system were made under conditions which provided the following possible sources of DHP: (1) water only fed (Daphnia in mixed model fed unlabled algae), (2) water only unfed, (3) water plus food (labled algae), and (4) food only.
