摘　　要：采用菲咯嗪法对黄渤海沿岸部分地点2009年表层水样以及山东荣成湾内的天鹅湖、近岸和远海部分站点2009~2011年采集的表层水样进行了Fe含量的测定,此外还检测了天津、荣成及日照采集的地下水水样。结果显示渤海沿岸除河北秦皇岛东山浴场,营口、秦皇岛西浴场、天津、东营支脉河口和昌邑沿岸表层水样的Fe（Ⅲ）以及Fe（t）浓度明显高于山东省黄海沿岸,而黄渤海沿岸各水样中Fe（Ⅱ）浓度均较低且差异不明显。荣成湾近岸和远海以及其内的天鹅湖站点水样的Fe（Ⅱ）、Fe（Ⅲ）和Fe（t）浓度周年变化不明显,Fe（t）浓度总体上为天鹅湖〉近岸〉远海。地下水中Fe（Ⅲ）浓度高于Fe（Ⅱ）,但一些地下水中Fe（Ⅱ）浓度仍处于较高水平。The Fe concentration in surface waters along the coast of Yellow Sea and Bohai Sea were determined according to modified Viollier＇ s method. The surface water samples of Rongcheng bay including Swan lake from 2009 to 2011, and the coastal groundwater samples in Tianjin, Rongcheng and Rizhao were also measured. Results showed that the Fe（ Ⅲ 〉 and Fe（t） concentrations in most sampling sites along the coast of Bohai Sea were higher than those of Yellow Sea. In Rongcheng bay, no obvious annual variation trend of the Fe（ Ⅱ ）, Fe（ Ⅲ） and Fe（t） concentrations was found. The highest Ye （t） concentration appeared in Swan lake, and the lowest one appeared in offshore site. The Fe（ Ⅱ ） concentrations in some groundwater such as Tianjin and Rongcheng were at high level even though the Fe （ Ⅲ ） concentrations in the costal groundwater were all higher than Fe （ Ⅱ ） concentrations.
