| 摘 要： | 对采集大连湾附近海域的沉积物中多环芳烃（PAHs)进行了定性和定量分析，并探讨了其在沉积物中的分布特征。大连湾表层沉积物中PAHs含量的变化范围为32．70－3558．88ng/g，平均值1152．08ng/g。大连湾表层沉积物中PAHs以油类污染为主。其含量分布，大连港附近海域最高，东北部靠近大连湾煤码头航道测站次之，由西北和东北向南逐步递减，呈现出明显的两点污染源特征。

| Abstract: | The paper presents the study of PAHs in surface sediment samples collected from Dalian Bay and nearby sea area. Concentrations of PAHs are quantitatively measured and distributing characteristics of these compounds in the area are discussed. The range of PAHs concentrations in the sediments is 32.70-3558.88ng/g,the mean concentration is 1152.08ng/g.It is main for PAHs in surface sediment to be contaminated.The PAH content in the sea area is highest near Dalian harbor, and takes second place in samples collected from the monitoring station near the northeast of Dlian Coal Wharf,and decreases gradually from northwest and northeast to south,showing the characteristics of two pointsource pollutiong. |
