摘要:
利用气相色谱-质谱联用(GC-MS)技术, 对2012 年10 月采自南中国34 个站位的表层、500 m 层、底层海水中的16 种多环芳烃(16PAHs)进行了检测分析。结果显示: 南中国海海水中16PAHs 的含量相对于其他类似广阔水域较低, 分布特征大致呈现500 m 层＞表层＞底层。经特征PAHs 组分分析判定南中国海海水中PAHs 主要来源于石油及其产品。

Distribution and origin of polycyclic aromatic hydrocarbons in the sea water of the South Sea
Abstract:
The sea water samples collected from the sea surface water, the 500 m depth water and the bottom water, respectively at the 34 survey stations in the South Sea in December 2012 were detected and analyzed by GC/MS. The results showed that the content of 16 PAHs in the South Sea was not higher compared to other similar broad waters and the distribution was roughly 500 m depth layer>surface>bottom. According to the characteristic of PAHs, it suggested that the PAHs in the South Sea mainly come from petroleum and its products.
