Toxicokinetics of Fluoranthene to the Amphipod, Leptocheirus plumulosus, in Water-only and Sediment Exposures

摘要

The ability of the equilibrium partitioning (EqP) and critical body residue (CBR) approaches to predict the toxicity of the polycyclic aromatic hydro- carbon, fluoranthene, to a standard sediment toxicity test organism, the amphi- pod Leptocheirus plumulosus was examined in a series of water-only and sediment exposures. Concentrations of fluoranthene in water that resulted in 50/100 mortality (10-d LC_50) were 39.2 (35.1-43.8, 95/100 C.I.) and 39.2 (34.1- 45.1, 95/100 C.I.) μg|liter in replicate tests.
