海洋中元素的迁移变化规律性及其理论的研究是海洋化学的一个主要任务。石桥雅义和东慎之介曾从宏观角度研究过此问题,认为溶于海水中元素的量主要由如下三个因素决定:(1)元素在地壳中的存在量;(2)元素通过河川进入海洋的难易程度;(3)元素进入海洋后沉积到海底比率的大小。这就是说,影响元素迁移的因素十分复杂,涉及到地球的形成和地壳的组成、岩石的风化作用、雨水的侵蚀溶解、元素的物理-化学特性、(介质)海水的pH与氧化-还原电位、无机和有机悬浮物对溶解元素的吸着作用,海洋生物的活动、以及洋底岩石圈的活动和大气圈的影响等等,直到目前,还只能说是初步了解,许
The regularity of the migration and variation of elements in the ocean and its theoretical study are one of the major tasks of ocean chemistry. Ishibashi Yasuyuki and Tohru Shinsuke once studied this problem from a macroscopical point of view. I think that the amount of elements dissolved in seawater is mainly determined by three factors as follows: (1) the amount of elements present in the earth’s crust; (2) The degree of difficulty of the ocean; and (3) the size of the elemental sediment to seabed ratio after entering the ocean. That is to say, the factors influencing the migration of elements are very complex, involving the formation of the earth and the composition of the crust, the weathering of rocks, the erosion and dissolution of rainwater, the physico-chemical properties of the elements, the pH of the (medium) seawater and the oxidation- reduction potential , The sorption of dissolved elements by inorganic and organic suspensions, the activity of marine organisms, the activity of the lithosphere on the ocean floor and the influence of the atmosphere, and so on, until now, it can only be said that the initial understanding
