英文摘要	用碱熔法处理样品,水沥取,用分光光度法测量了采集自福建省兴化湾、九龙江河口和东山湾3个海湾潮间带沉积物岩心的碘分布。兴化湾、九龙江河口和东山湾3岩心中的碘含量分别为2.5~43.7,17.3~39.6和11.3~29.1Mg/kg。3个沉积物岩心中的碘含量稍高于福建省的土壤的碘含量,与我国海域的沉积物碘含量在同一水平,但明显低于文献报道的开阔海域沉积物的碘含量。兴化湾和东山湾沉积物中的碘与有机碳含量有较好的相关性;在九龙江河口采集的岩心中的碘与有机物碳含量的相关性较差。推测海洋源的沉积物碘与有机碳含量相关性较好,而陆源沉积物的碘与有机碳含量相关性较差。; Three sediment cores are collected from the intertidal zone of the Xinhua Bay,the Jiulong Estuary and the Dongshan Bay of Fujian Province,southeastern China.The iodine contents in the sediment samples sliced by the three cores are measured by a spectrophotometric method after alkali fusion and leached with water.The results show that the iodine contents are between 2.5and 43.7mg/kg in the core from the Xinhua Bay,and 17.3and 39.6mg/kg in that from the Jiulong Estuary and 11.3and 29.1mg/kg in that from the Dongshan Bay respectively.The iodine contents in sediment samples of this study are higher than that of China's soils and at same level with those of China's Seas sediment.The iodine contents are well correlated with the organic carbon content in the sediments from the Xinhua Bay and the Dongshan Bay,respectively,where matter may mainly from the ocean.The correlation between iodine and organic carbon content is not well close in the sediments from the Jiulong Estuary,where the material is mainly terrigenous.It is shown that the correlation between iodine and organic carbon contents in the sediments from the ocean is well,but not close in that terrigenous fraction.; 国家自然科学基金资助项目“应用129I的海洋铁锰结壳年代学”(41073044)
