Anhui Province is the most important energy production base for eastern China. Many large pithead coal-fired power plants are being operated in the coal-rich Huainan and Huaibei coalfields in northern Anhui. To assess the environmental risks of local coal-fired power plants, a complete atmospheric emission inventory of F, As, Se, Cd, Sb, Hg, Pb, and U from coal-fired power plants in Anhui was compiled by a simple mass-balance-based method. The results indicated that the atmospheric emissions of F, As, Se, Cd, Sb, Hg, Pb, and U in 2017 from the Anhui coal-fired power plants were 578 t, 2.01 t, 15.3 t, 0.57 t, 0.18 t, 2.80 t, 23.7 t, and 0.099 t, respectively. The emission factor is the major contributor to the uncertainties in this inventory. With increasing energy demand by the more developed eastern China region, the atmospheric emissions of volatile hazardous elements will continue to increase in the near future.
安徽省是中国东部最重要的能源生产基地。在安徽省北部富产煤炭的淮南和淮北煤田，许多大型坑口燃煤电厂正在运营。为了评估当地燃煤电厂的环境风险，采用简单的基于质量平衡的方法，编制了一份来自安徽省燃煤电厂的完整大气排放清单，列出了 F、As、Se、Cd、Sb、Hg、Pb 和 U 等元素的排放情况。结果表明，2017 年安徽省燃煤电厂 F、As、Se、Cd、Sb、Hg、Pb 和 U 的大气排放量分别为 578 吨、2.01 吨、15.3 吨、0.57 吨、0.18 吨、2.80 吨、23.7 吨和 0.099 吨。排放因子是该清单不确定性的主要来源。随着中国东部地区能源需求的增加，在不久的将来，挥发性有害元素的大气排放量将继续增加。
