摘要
采用气相色谱/质谱对大连湾表层沉积物中11种甾醇进行了监测,探讨了大连湾17个站位的表层沉积物中甾醇的分布特征。结果表明,大连湾17个站位的表层沉积物中11种甾醇的含量范围为1.627×10-6～34.617×10-6;甾醇分布呈现出近岸区高于离岸海区,近排污口区高于远排污口区的态势;甾醇种类主要为C27甾醇和C29甾醇;其来源主要是大量生活污水的输入。
11 sterols in the surface sediment samples in Dalian Bay were determined by GC/ MS,and the distribution characteristics at 17 stations in this area were discussed.The results show that the total concentration range was（0~6.833）×10-6,the sterols range was（1.627~34.617）×10-6.The distribution appeared that the concentration of total sterols around the sewage outfall was higher than that far away from the outfall.The main kinds of sterols were C27 sterols and C29 sterols and the source of sterols was a large number of domestic sewage.
