[(sup14)C]naphthalene and phenanthrene were oxidized to (sup14)CO(inf2) without a detectable lag under strict anaerobic conditions in sediments from San Diego Bay, San Diego, Calif., that were heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) but not in less contaminated sediments. Sulfate reduction was necessary for PAH oxidation. These results suggest that the self-purification capacity of PAH-contaminated sulfate-reducing environments may be greater than previously recognized.
[(sup14)C]萘和菲在加利福尼亚州圣地亚哥湾圣地亚哥的沉积物中,在严格的厌氧条件下被氧化为(sup14)CO(inf2),没有可检测到的滞后,这些沉积物受到多环芳烃(PAHs)的严重污染,但在污染较轻的沉积物中则没有。硫酸盐还原是 PAH 氧化的必要条件。这些结果表明,受 PAH 污染的硫酸盐还原环境的自净能力可能比以前认识到的更大。
