调查了解沿岸河口区痕量金属浓度及形态变化,是研究河口水化学及河口环境化学的重要课题,对进一步了解微量元素在海洋中的循环过程更有重要意义,关于锌等四种痕量金属在海洋中的存在形态及其研究,国外已有不少报道,随着环境科学的不断发展,研究我国海湾及河口海区的痕量金属存在形态和转移机理,是当前普遍重视的课题。由于河口环 Investigation of trace concentrations and morphological changes in coastal estuarine areas is an important issue for the study of chemical chemistry in the estuary and environmental chemistry in estuaries. It is of great significance to further understand the cyclic processes of trace elements in the oceans. For the four trace metals, such as zinc, There are many reports in foreign countries. With the continuous development of environmental science, studying the existing forms and transfer mechanisms of trace metals in the gulf and estuarine areas of our country is a topic of universal importance at present. Due to estuary ring
