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。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＆gt;surface＆gt;bottom. According to the characteristic of PAHs, it suggested that the PAHs in the South Sea mainly come from petroleum and its products.
