摘要
根据收集的南通市各类人为氨排放源的活动水平数据,采用合理的估算方法和排放因子,估算了2009年南通市的人为源大气氨排放量。结果表明,2009年南通市人为源大气氨排放量为60.02 kt,其中,畜禽源和氮肥使用是两个最大排放源,氨排放量分别为31.54 kt和23.43 kt,分别占南通市大气氨排放总量的52.5%和39.0%。畜禽源中生猪是NH3排放最大贡献源,占畜禽源排放总量的46.4%,其次是家禽,其贡献率为36.4%。南通市氨平均排放强度为6.59 t.km-2.a-1。
The ammonia emissions of Nantong in 2009 are estimated based on the activity data and emission factors of various ammonia sources. Results show that the anthropogenic ammonia emissions in Nantong reached 60. 02 kt in 2009. The animal hus- bandry and application of nitrogenous fertilizer were the two largest contributors of ammonia emissions in Nantong, emitting 31.54 kt and 23.43 kt, respectively which represents 52. 5% and 39.0% of the total ammonia emissions. The pig was the largest con- tributor among the livestock sources, accounting for 46.4% of the livestock emissions, followed by fowl with 36. 4% The average ammonia emission intensity in Nantong reached 6. 59 t ·km-2 . a m 2009.
