An integrated inventory of atmospheric antimony (Sb) emissions from anthropogenic activities in China is compiled for the years 2005-2009. Emissions are estimated for all major anthropogenic sources for the first time. We estimate that the national emissions of antimony are 818 metric tons (t) in 2009, with the largest contribution from coal combustion at 61.8% of the total, while 26.7% of Sb is emitted from nonferrous metals smelting. Emissions are heaviest in Guizhou province, mainly due to small-scale combustion of high-Sb coal without emission control devices, and in Hunan province, where extensive smelting occurs. Furthermore, Sb emissions from 2188 large point sources and area sources are distributed within latitude/longitude-based grids with a resolution of 30 min × 30 min where Sb emissions are largely concentrated in highly populated and industrialized southwestern China, the east central region, and coastal areas. The uncertainties in our bottom-up inventory are quantified as -11% to 40% by Monte Carlo simulation. We recommend continuous field testing of coal combustors and smelters in China to improve the accuracy of these estimates.
本文编制了 2005-2009 年中国人为活动大气锑排放综合清单。这是首次对所有主要人为源的锑排放进行估算。我们估计，2009 年全国锑排放量为 818 公吨，其中最大的贡献来自煤炭燃烧，占总量的 61.8%，而 26.7%的锑则来自有色金属冶炼。贵州省的排放量最大，主要是由于没有排放控制装置的小规模燃烧高锑煤所致，而湖南省则广泛存在冶炼活动。此外，2188 个大型点源和区域源的锑排放量分布在基于经纬度的网格中，分辨率为 30 分钟×30 分钟，锑排放量主要集中在中国人口密集和工业化程度较高的西南部、中东部地区和沿海地区。通过蒙特卡罗模拟，我们将本底清单的不确定性量化为-11%至 40%。我们建议在中国持续对燃煤炉和冶炼厂进行实地测试，以提高这些估算的准确性。
