对青岛浴场表层海水中正构烷烃和多环芳烃组成、分布及来源进行分析。分别在第一海水浴场(以下简称一浴)、第二海洋浴场(以下简称二浴)、黄岛金沙滩海水浴场和五四广场4个站位采集表层海水,经萃取、浓缩后用气质联用法(GC-MS)进行测定。结果表明,各站位海水中正构烷烃谱图均为双峰型,主峰碳和奇偶优势各不相同,正构烷烃(∑n-alk)含量为1.14-25.47μg/L；多环芳烃(∑PAHs)含量为201.01-314.30 ng/L,以二、三环的萘、苊、二氢苊、芴、菲、荧蒽为优势组分；一浴、二浴和五四广场海水正构烷烃以石油、化石燃料的不完全燃烧等人类活动输入为主,金沙滩海水正构烷烃以硅藻、细菌等浮游生物的输入为主；一浴、二浴和金沙滩海水多环芳烃主要来源于石油污染和化石燃料燃烧的混合源,五四广场海水多环芳烃主要来自石油源；正构烷烃特征比值 CPI,OEP,Pr/Ph 均指示四种海水受到石油污染。
對青島浴場錶層海水中正構烷烴和多環芳烴組成、分佈及來源進行分析。分彆在第一海水浴場(以下簡稱一浴)、第二海洋浴場(以下簡稱二浴)、黃島金沙灘海水浴場和五四廣場4箇站位採集錶層海水,經萃取、濃縮後用氣質聯用法(GC-MS)進行測定。結果錶明,各站位海水中正構烷烴譜圖均為雙峰型,主峰碳和奇偶優勢各不相同,正構烷烴(∑n-alk)含量為1.14-25.47μg/L；多環芳烴(∑PAHs)含量為201.01-314.30 ng/L,以二、三環的萘、苊、二氫苊、芴、菲、熒蒽為優勢組分；一浴、二浴和五四廣場海水正構烷烴以石油、化石燃料的不完全燃燒等人類活動輸入為主,金沙灘海水正構烷烴以硅藻、細菌等浮遊生物的輸入為主；一浴、二浴和金沙灘海水多環芳烴主要來源于石油汙染和化石燃料燃燒的混閤源,五四廣場海水多環芳烴主要來自石油源；正構烷烴特徵比值 CPI,OEP,Pr/Ph 均指示四種海水受到石油汙染。

The compositions and sources of n-alkanes and polycyclic aromatic hydrocarbons (PAHs)in the surface seawater samples collected from 4 sites in Qingdao offshore (the First Beach,the Second Beach,Golden Beach and the May Fourth Square)were analyzed by gas chromatography-mass spec-trometry method (GC-MS).The results showed that the concentrations of ∑n-alk were between 1.14 and 25.47μg/L.The n-alkanes in all four sites’seawater showed bimodal patterns,but the dominant peak and parity advantage were different.The concentrations of ∑PAHs changed between 201.01 and 314.30μg/L.Naphthalene with two or three benzene rings,acenaphthene,acenaphthene,fluorene, phenanthrene,and fluoranthene were the dominant components.N-ankanes in the First Beach,the Sec-ond Beach,and the May Fourth Square mainly came from anthropogenic incomplete combustions of crude oil and fossil fuel,while N-alkanes in Golden Beach came from plankton such as diatoms and bac-teria.PAHs in seawater samples of the First Beach,the Second Beach,and Golden Beach were all mainly from petroleum pollution and fossil fuel combustions,while PAHs in the May Fourth Square were mainly from petroleum pollutions.Diagnostic ratios (CP,OEP and Pr/Ph)showed that all the four sites’seawater surfers from petroleum pollution.
