| Abstract: |
| 10 samples of sediments obtained from the South Mid-Atlantic Ridge were measured for the abundances and distributions of polycyclic aromatic compounds (PAHs). The total concentrations of PAHs (∑PAHs) ranged from 2.768 to 9.826 μg/g dry sediment. The ∑PAHs was higher in sample 22V-TVG10 and sample 26V-TVG05 which were close to hydrothermal fields, with the lowest value in sample 22V-TVG14 which was farthest from hydrothermal fields, suggesting a probable hydrothermal origin of ∑PAHs of samples. Approximately nine kinds of PAHs were identified, and low molecular mass tricyclic and tetracyclic aromatic compounds were predominant in the samples. The concentrations of fluoranthene which were typical as hydrothermal alteration compounds were the highest among PAHs with dry weight between 0.913-3.157 μg/g. The phenanthrene homologue was most abundant in the samples, and the ratios between parent phenanthrene and methylphenanthrene which probably reflected the degree of hydrothermal alteration ranged from 0.097 to 1.602. The sample 22V-TVG10 possessing a maximum ratio value showed the intense influence of the hydrothermal alteration on this sample, which might further imply that PAHs in sediments were mainly derived from the hydrothermal alteration. |

| 我们测试了南大西洋洋中脊附近10个海底沉积物中芳香化合物的组成和丰度。样品中总芳香化合物含量在2.768-9.826μg/g沉积物干重之间, 22V-TVG10和26V-TVG05站位样品中含量较高, 最低值出现在22V-TVG14站位, 表明样品中芳香化合物含量与热液活动密切相关, 暗示出样品中芳香化合物具有热液起源。其中主要有9种芳香化合物及其同系物被检测出来。被检测到的芳香化合物以三环和四环等低分子质量芳香化合物为主, 其中含量最高的为荧蒽, 含量在0.913-3.157μg/g沉积物干重之间。样品中检测到的芳香化合物种类最丰富的为菲同系物。菲与甲基菲的比值范围在0.097-1.602之间, 最大值出现在22V-TVG10站位, 其次为26V-TVG05和22V-TVG11站位, 表明这些站位样品受热液蚀变影响程度较大, 也进一步暗示出样品中多环芳香化合物可能主要来源于海底热液蚀变。 |
