| 摘 要： | 通过 3个航次对厦门西港表层海水中 16种优先监控的PAHs的污染状况进行不同季节的连续调查 .结果表明 :表层海水中PAHs的含量与组成具有明显的时间差异 .在 4月和 10月的PAHs含量较 7月高 ;PAHs的组成在 4月以 2环的萘为优势组分 ,在 7月以 3环的苊烯为优势组分 ,10月以 4环的为优势组分 .分析 3个航次的调查结果发现 :厦门西港表层海水中的PAHs主要来源于石油类物质的输入 .厦门西港表层海水中各种PAHs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 ,但个别组分如蒽、苯并 a]芘的含量已达到生态毒理评价标准 . |

| Abstract: | An investigation on levels of polycyclic aromatic hydrocarbons (PAHs) in surface water of Xiamen Harbor has been conducted on spring, summer and autumn cruises in 2001 and at six locations. The results showed that the concentration and composition of PAHs in the surface water were variable. The pollution levels of PAHs in April and October were higher than that in July concentrations of total. PAHs in the surface water were mainly dominated by naphthalene (2 rings) in April, acenaphthene (3 rings) in July and chrysene (4 rings) in the October. The concentrations of anthracene and benzo(a)pyrene in surface water was higher than the toxicity guidelines. The origin of PAH pollution in surface water of Xiamen Harbor was mostly petrogenic. |
