| studies on bioremediation of polycyclic aromatic hydrocarbon-contaminated sediments: bioavailability, biodegradability, and toxicity issues. | the widespread contamination by polycyclic aromatic hydrocarbons (pahs) has created a need for cost-effective bioremediation processes. this research studied a chronically pah-contaminated estuarine sediment from the east river (er; ny, usa) characterized by high concentrations of pahs (approximately 4-190 ppm), sulfide, and metals and a marine sediment from new york/ new jersey harbor (ny/njh; usa) with only trace quantities of pahs (0.1-0.6 ppm). the focus was to examine the relationship betwe ... | 2003 | 12627632 |
