本文件审查了目前对全球汞排放的了解情况，并提出了一份关于2000年全球人为汞向大气排放的新清单。向全球大气排放的最大汞来自化石燃料的燃烧，主要是公用事业、工业和住宅锅炉中的煤炭。多达三分之二的总排放量的ca。2000年，全世界所有人为汞排放源中有2 190吨来自化石燃料的燃烧。燃煤产生的汞排放量比燃油产生的汞排放量高出一到两个数量级，具体情况视国家而定。2000年，各种工业生产过程占全球人为汞排放量的30%。这一来源类别的排放主要来自使用汞技术的黄金生产。2000年，亚洲国家占全球人为汞排放量的54%，其次是非洲（18%）和欧洲，包括俄罗斯的欧洲部分（11%）。中国是人类活动汞排放量最高的10个国家之首。中国汞排放量超过600吨，占全球汞排放量的28%。预计到2020年，全球人为源汞排放量的未来变化应在当前估计值的+/- 20%范围内，但应非常谨慎地对待这一评估。这些地图在一份配套文件（威尔逊等人，2005.全球人为汞大气排放的空间分布。大气环境，在这个问题上）。(c)2006爱思唯尔有限公司保留所有权利。
The paper reviews the current state of knowledge regarding global emissions of mercury and presents a new inventory of global emissions of mercury to the atmosphere from anthropogenic sources for the year 2000. The largest emissions of Hg to the global atmosphere occur from combustion of fossil fuels, mainly coal in utility, industrial, and residential boilers. As much as two-thirds of the total emission of ca. 2190 ton of Hg emitted from all anthropogenic sources worldwide in 2000 came from combustion of fossil fuels. Emissions of Hg from coal combustion are between one and two orders of magnitude higher than emissions from oil combustion, depending on the country. Various industrial processes account for additional 30% of Hg emissions from anthropogenic sources worldwide in 2000. Major contribution to emissions from this source category comes from gold production using Hg technology. The Asian countries contributed about 54% to the global Hg emission from anthropogenic sources in 2000, followed by Africa (18%) and Europe, including the European part of Russia (11%). China heads the list of the 10 countries with highest Hg emissions from anthropogenic activities. With more than 600 ton of Hg, China contributes about 28% to the global emissions of mercury. \It is expected that future changes of Hg emissions from anthropogenic sources worldwide until the year 2020 should be within +/- 20% of the current estimates, although this assessment should be treated with great caution.Emission estimates for various continents presented in this paper were used to prepare global emission maps. These maps are presented in a companion paper (Wilson et al., 2005. Spatial distribution of global anthropogenic mercury atmospheric emissions. Atmospheric Environment, in this issue).
