摘要

摘要: 2007年9月进行了2007南黄海海洋环境调查，并采集各个调查站位的表层、中层、底层海水及表层沉积物。利用液-液萃取法对采集到的样品进行前处理，并用气相色谱-质谱法检测海水中的多环芳烃。结果显示，监测站位中表层海水中总多环芳烃的含量范围是15.76～233.39 ng/L，南黄海中部海水中多环芳烃的组成以2环的萘为优势组分；各种多环芳烃的含量与国际生物学组织或国家制定的评价水生生物暴露于水体的安全食用标准相比虽未超标，但个别组分如荧蒽的含量已达到生态毒理评价标准。

Abstract: Marine surface sediments and sea water samples from the surface, middle and bottom layers were collected from the South Yellow Sea of China. The samples were pretreated by liquidliquid extraction and the 16 polycyclic aromatic hydrocarbons (PAHs) in the samples were determined by gas chromatographymass spectrometry (GCMS). The results show that the range of total PAHs is 15.76～233.39 ng/L in surface water and PAHs in the water samples from central South Yellow Sea are dominated by naphthalene (2 rings). Content of PAHs compounds don′t exceed the safety guidelines proposed by International Biology Organization or governments, but the individual compound, such as fluoranthene content has reached ecotoxicological evaluation criteria.
