Cooperative Research on Geochemistry of the Klang River Estuary, Malaysia

这项提议要求继续提供经费，为期24年。 几个月后，布鲁斯W.纳尔逊，教授 弗吉尼亚大学环境科学系， 易卜拉欣，环境科学系，Pertanian大学 马来西亚雪兰莪州巴生河的地球化学 河口，开始在NSF授权号INT 8411319。 他们的研究将 为热带河口系统提供了新的信息， 控制河口中元素行为的过程。 这项研究将包括对二氧化硅和微量元素的行为的研究。 淡水-盐水混合带中的金属。 以前的研究 结果表明，有限范围的污染物集中在 河口的沉积物 将尝试确定是否 这些污染物很容易进入食物链， 海洋，是海洋污染的主要因素。 吸附作用 和解吸的二氧化硅作为一个功能的盐度在混合区 还将研究向海洋的运输。 美国和马来西亚 合作者是备受尊敬的科学家，他们过去的合作 已出版了一些出版物。 该项目与 发展中国家科学计划的目标， 旨在提高美国科学家与 工程师和发展中国家的同行， 交流科学信息、思想、技能和技术， 通过在互利问题上的合作。

This proposal requests funds for continuation, for a period of 24 months, the cooperative research by Dr. Bruce W. Nelson, Professor of Environmental Sciences, University of Virginia, and Dr. Zelina Ibrahim, Department of Environmental Sciences, Universiti Pertanian Malaysia, Selangor, Malaysia, on the geochemistry of the Klang River estuary, begun under NSF Grant No. INT8411319. Their study will provide new kinds of information on a tropical estuarine system and the processes that govern element behavior in estuaries. The research will include a study of the behavior of silica and trace metals in the freshwater-saltwater mixing zone. Previous research results show that a limited range of pollutants is concentrated in the sediments of the estuary. An attempt will be made to determine if these pollutants are easily incorporated into the food chain, reach the sea, and are factors in marine pollution. The role of adsorption and desorption of silica as a function of salinity in the mixing zone and transport to the sea also will be studied. The U.S. and Malaysian collaborators are highly respected scientists whose past collaboration has resulted in a number of publications. This project is relevant to the objectives of the Science in Developing Countries Program which seeks to increase the level of cooperation between U.S. scientists and engineers and their counterparts in developing countries through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit.
