BIOSIS COPYRIGHT: BIOL ABS. Most polycyclic aromatic hydrocarbons (PAHs) entering aquatic systems reside in sediments and in the storage lipids of the benthic biota. Massive amounts of PAHs reach estuarine systems and threaten their ecosystems. Copepods abound in the estuarine benthos, where they are an important component of food webs. The accumulation of sediment-associated (14C)fluoranthene was examined in adult females of two species of sediment-dwelling copepods, Schizopera knabeni and Coullana sp., collected from a Louisiana salt marsh. Accumulation was measured throughout a short- (24 h) and a long-term (10-day) exposure to concentrations in the sediment ranging from 0 to 1652 nmol (g dry wt.)-1. Fluoranthene apparent steady state body residue was reached very rapidly (12 h) at all concentrations for both species. Lipid and organic-carbon-normalized bioaccumulation factors (BSAFs) calculated at day 1 were 0.57-0.80 for S. knabeni and 0.35-0.71 for Coullana sp. Fluoranthene body burden
