摘要
多环芳烃（PAHs）在环境中的污染越来越受到重视。文章采集海口湾7个代表性点位表层水样,分析其中16种多环芳烃（PAHs）的含量,探讨其可能的来源。结果表明：海口湾表层水体中总PAHs平均值为33.6 ng/L,变化范围为12.3~108 ng/L,PAHs的组成以2～4环为主。分析荧蒽/芘的比值表明,海口湾水体中的多环芳烃主要来源于石油污染。
Contamination with polycyclic aromatic hydrocarbons（PAHs）in environment attracts more concerns.The surface seawater samples at 7 sites were collected in Haikou Bay.The concentrations of 16 individual PAHs were analyzed and possible sources were discussed.Results showed that average concentration of PAHs was 33.6 ng/L and varied from 12.3 to 108ng/L.Individual composition of PAHs was characterized by 2~4 rings in samples.The ratios of（Fl/Py）showed that PHAs of seawater in Haikou Bay were from the contamination of oils.
