Evaluation of mercury emissions to the atmosphere from coal combustion, China.
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.
