摘要
燃煤大气排放汞是主要的人为大气汞污染源。1995年中国燃煤大气排放汞计算总量为213.8t,约占当年全球大气排放汞总量4000t的5%。从1978~1995年,中国燃煤消耗总量增加了4倍,燃煤大气汞排放总量以每年5%的速度递增。据此计算2000年在中国燃煤大气汞排放总量可达到273t。控制和解决燃煤大气汞排放量,已经成中国在经济快速发展的同时所面临的一个重要的环境问题。
Mercury emissions from the coal smoke is the main source of anthropogenic discharge and mercury pollution in atmosphere. The calculated total amount of mercury emissions of China in 1995 is approximately 213.8 tonnes, which accounts for c. 5% of estimated total global discharge of 4000 tonnes in the same period. From 1978 to 1995, total coal consumption increased fourfold. Based on these data it is estimated that the mercury emissions will increase at a rate of 5% a year, and the predicted emissions will be 273 tonnes in China in 2000. Controlling and solving mercury emissions from coal combustion are among the most important environmental tasks facing China.
