摘　　要：通过离子色谱离线螯合和ICP-MS对青岛市汇泉湾、太平湾、浮山湾采集的海水样品进行分析,得到了该海域表层海水中微量元素质量比的可靠数据,并对表层海水中微量元素的分布特征及其影响因素进行了探讨。将分析结果与国家海水标准进行比较表明,该海域海水中微量元素质量比符合国家一级海水标准。对该海域表层海水微量元素的分布特征的研究表明,近岸和远岸表层海水中微量元素的质量比差别很小,而不同于沿岸海区质量比高,离岸远处质量比较低的一般规律。其主要原因是该海域的人为污染程度小,再加上其特殊的海岸地形以及水动力条件,有利于溶解物质的扩散、迁移和稀释。An off-line chelation system combined with ion chromatography and ICP-MS was developed to make quantitative determination of trace elements in seawater. Accurate data of trace element concentrations in surface seawater at the site of the 2008 Olympic sailing games in Qingdao were obtained by using this method. The distribution features of these elements and the influencing factors were discussed. The trace element contents at this site were in accordance with the Chinese National Standard for the first grade seawater, indicating good seawater quality. The concentrations of most trace elements did not show any decreasing trend with increasing in the distance from the shore, because of the special coastal landform and the insignificant anthropogenic input in the area.
