Cumulative 14CO2 recovered from incubations with [14C]-naphthalene (NAP), phenanthrene (PHE), anthracene (ANT), fluoranthene (FLU), pyrene (PYR), or benz[a]anthracene (BaA) by surface (0–4 cm) sediment cores 4571-2 (solid bar) and 4567-24 (open bar) during incubation at 21°C for 12 days, as compared to acid-killed controls. Bars are the averages and SD from triplicate incubations. *values for cumulative 14CO2 recovered were equal or below that of the respective control incubations.
