在这项研究中,我们根据消耗或产出数据和排放因子,估算了1990年至2010年中国地区人为来源的大气Cd排放量。2010年,中国向大气排放的Cd约为2186吨,其中约77%来自有色金属冶炼,约14%来自燃煤。由于采用了节能和清洁生产技术,镉总排放量的时间变化有两个增长期(1990-2000年和2001-2010年)和一个较短的减少量(2000-2001年)。总体而言,由于经济的快速增长,大气镉的排放量从1990年的474亿吨增加到2010年的2186亿吨,而节能和清洁生产技术自2000年以来一直在使用。大气Cd排放的空间分布主要以有色金属冶炼和燃煤为主。湖南省和云南省因有色金属冶炼产量高而排放量高,山东省因煤炭消耗量高和有色金属产量适中而排放高。
In this study, we estimated atmospheric Cd emissions from anthropogenic sources in China from 1990 to 2010 on the basis of consumption or output data and emission factors. China emitted approximately 2186 t Cd to the atmosphere in 2010, with approximately 77% and 14% of the emissions arising from non-ferrous metal smelting and coal combustion, respectively. Temporal changes in the total Cd emissions were characterized by two periods of increase (1990–2000 and 2001–2010) and a short period of decrease (2000–2001) due to application of energy-saving and cleaner production technologies. Overall, atmospheric Cd emissions increased from 474 t in 1990 to 2186 t in 2010 due to rapid economic growth, whereas energy-saving and cleaner production technologies have been in use since 2000. Spatial distribution of the atmospheric Cd emissions was dominated primarily by non-ferrous metal smelting and coal combustion. Emissions are high in Hunan and Yunnan Provinces because of high production non-ferrous metal smelting and in Shandong Province because of high coal consumption and moderate non-ferrous metal production.
