To understand the uptake, depuration, and bioconcentration factors (BCFs) under the worst-case conditions, the authors exposed 84 mosquito fish to reclaimed water under static renewal for 7 d, followed by a 14-d depuration phase in clean water. Characterization of the exposure media revealed the presence of 26 pharmaceuticals, whereas only 5 pharmaceuticals\u2014caffeine, diphenhydramine, diltiazem, carbamazepine, and ibuprofen\u2014were present in the organisms after only 5 h of exposure. Caffeine, diltiazem, and carbamazepine were quickly taken up by mosquito fish following a similar uptake curve. Diphenhydramine and ibuprofen, on the other hand, were more gradually taken up by mosquito fish but were also eliminated fairly quickly, resulting in the 2 shortest depuration half-lives at 34 h and 32 h, respectively. For comparison, BCFs based on rate constants (BCFb), steady-state concentrations (BCFa), and saturation-state concentrations (BCFc) were calculated. Values of BCFb ranged from 0.23 to 29 and increased in the order of caffeine\u2009&amp;lt;\u2009carbamazepine\u2009&amp;lt;\u2009diltiazem\u2009&amp;lt;\u2009diphenhydramine\u2009&amp;lt;\u2009ibuprofen. Values of BCFa and BCFc ranged from 2.0 to 28 and increased in the order of carbamazepine\u2009&amp;lt;\u2009caffeine\u2009&amp;lt;\u2009diltiazem\u2009&amp;lt;\u2009diphenhydramine\u2009&amp;lt;\u2009ibuprofen.
