摘要
回顾全球所经历的主要汞污染事件,引述国外科研工作者对全球汞污染与汞排放的调查和研究成果,重点介绍金矿开采对环境的污染与危害,揭示造成亚马逊流域汞污染的深层根源。分析今后全球防止汞污染的主要措施:一是主要工业化国家将进一步研究和改善工业领域相关行业的工艺技术水平,趋向无汞产品和无汞工艺,以减少自身的汞污染与排放;其二,发达国家陆续立法禁止汞的自由贸易和出口。发达国家对汞的出口限制将促使发展中国家相关行业(特别是小金矿)采取汞的替代工艺,从而减少全球性汞污染与排放。
Reviewed the incidents of mercury pollution in the world, cited foreign researchers results about global mercury pollution and mercury emissions, this paper emphatically introduces the environmental pollution and harm of gold mining, highlights the Brazilian gold mining in the Amazon ecosystem pollution and harm. The main measures of preventing global mercury pollution in future are analyzed： First, the major industrialized countries will further improve the research and technology of related industries in industrial area, tend to mercuryfree products and mercury-free processes, to reduce their own emissions of mercury pollution, second, the developed countries have legislation against the freedom of mercury trade and export, which will enable the developing cotmtries related industries（ particularly small gold）to replace the mercury process, thereby reducing global mercury pollution emissions.
