Bacterial mineralization of [7-14C]benzo[a]pyrene (BaP) to 14CO2 was enhanced by the presence of nonaqueous phase liquids (NAPLs). Mineralization of BaP was affected differently by different NAPLs, and the mode of enhancement of mineralization by a NAPL most likely occurred by a combination of cometabolic and physical effects. Mineralization was enhanced to the greatest extent when BaP was dissolved in a high-boiling distillation product of diesel fuel.
