Acid rain in Asia 总被引:3,自引:0,他引:3
Acid rain has been an issue of great concern in North America and Europe during the past several decades. However, due to the passage of a number of recent regulations, most notably the Clean Air Act in the United States in 1990, there is an emerging perception that the problem in these Western nations is nearing solution. The situation in the developing world, particularly in Asia, is much bleaker. Given the policies of many Asian nations to achieve levels of development comparable with the industrialized world—which necessitate a significant expansion of energy consumption (most derived from indigenous coal reserves)—the potential for the formation of, and damage from, acid deposition in these developing countries is very high. This article delineates and assesses the emissions patterns, meteorology, physical geology, and biological and cultural resources present in various Asian nations. Based on this analysis and the risk factors to acidification, it is concluded that a number of areas in Asia are currently vulnerable to acid rain. These regions include Japan, North and South Korea, southern China, and the mountainous portions of Southeast Asia and southwestern India. Furthermore, with accelerated development (and its attendant increase in energy use and production of emissions of acid deposition precursors) in many nations of Asia, it is likely that other regions will also be affected by acidification in the near future. Based on the results of this overview, it is clear that acid deposition has significant potential to impact the Asian region. However, empirical evidence is urgently needed to confirm this and to provide early warning of increases in the magnitude and spread of acid deposition and its effects throughout this part of the world. 相似文献

F. B. Pyatt 《The Environmentalist》1987,7(3):197-200
Summary This article presents data on acid precipitation in various sites in Norway and Sweden during the period of the latter part of July, until mid August 1986. Areas appearing particularly vulnerable are highlighted and some implications are discussed. Data from two widely separated glaciers are also presented.Dr. Brian Pyatt is the Section Leader and Principal Lecturer in Ecology in the Department of Life Sciences at Trent Polytechnic, Nottingham. His primary research interests lie in the areas of environmental pollution and the ecology of near-Arctic areas. 相似文献
