Anthropogenic Atmospheric Mercury Emissions Inventory And Analysis In China

According to the atmospheric mercury in natural ecology and people’s life of all kinds of species have no distance, restrictive hazard severity, it can be defined as a strong influence of pollutants. With the development of economy, anthropogenic atmospheric mercury has become the current atmosphere to the country of one of the high degree of cleanliness hazard pollutants. Due to the international human activities on the record of the release of atmospheric mercury project has not been implemented, so the atmospheric mercury the research of the origin and trajectory of pollutants even in the international scientific community is still a science difficult problem. For the above situation, in order to more effectively to severe atmospheric mercury pollution situation in a timely manner of coping strategies, our country should quickly implement for human activities of atmospheric mercury release specific situation to explore.The purpose of this paper is analysis and integration to our country industry sector and data records of each year. Make depth analysis of China’s true national situation and reality, draw lessons from the international forefront of science and technology of test conclusion, to build China’s release of atmospheric mercury source specific human activity system and Chinese for the source of atmospheric mercury emissions list, and make it meet the classification of the specific conditions of the statistics of pollutant source and build system.The results show that our country in 2012 caused by human activities is recorded in the atmospheric mercury emissions.The five provinces with the highest emission amount were Henan, Inner Mongolia,Shandong,Guizhou,Yunnan, the sum of its emissions accounted for 36.14% of the national total emission. Qinghai,Hainan and Beijing were the province of the lowest emission amount, they all below 3tons.And in which coal combustion emission 351.68 tons, oil combustion emission 19.34 tons, non-ferrous metal smelting emission 94.01 tons, cement production emission 37.24 tons,iron and steel production emission 35.42 tons and waste incinerators emission 7.31 tons.The total amount mercury was 545 tons.According to the paper indicates that the regional differences shows : mercury emissions from anthropogenic sources is largest in the Mid-south China region was 154.42 tons, is 1.1 ~ 5.2 times of the other regional emissions, contribution rate is as high as 28%.In addition to Northeast and Northwest emissions were 38.15 tons and 29.83 tons. North and Southwest China emissions were 98.15 tons and80.92 tons.The east China region emissions were 143.56 t,just below the Mid-south China region.
