摘要
Sea surface microlayer (SML) and sea water samples (SSW) collected in the Gerlache Inlet Sea (Antarctica) were analysed for n-alkanes and polycyclic aromatic hydrocarbons (PAHs). The SML is a potential enrichment site of hydrophobic organic compounds compared to the underlying water column. Total concentration ranges of n-alkanes and PAHs (dissolved and particulate) in subsurface water (-0.5 m depth) were 272-553 ng l(-1) (mean: 448 ng l(-1)) and 5.27-9.43 ng l(-1) (mean: 7.06 ng l(-1)), respectively. In the SML, the concentration ranges of n-alkanes and PAHs were 353-968 ng l(-1) (mean: 611 ng l(-1)) and 7.32-23.94 ng l(-1) (mean: 13.22 ng l(-1)), respectively. To evaluate possible PAH contamination sources, specific PAH ratios were calculated. The ratios reflected a predominant petrogenic input. A characterisation of surface active substances was also performed on SML and SSW samples, both by gas bubble extraction, and by dynamic surface tension measurements. Results showed a good correlation between n-alkanes, PAHs and refractory organic matter. (C) 2008 Elsevier B.V. All rights reserved.
