The emission inventory and spatial distribution characteristics of anthropogenic ammonia in 2019 of Hebei Province
Based on the statistical data of the activity level of anthropogenic ammonia emission sources in 2019 of Hebei Province,the ammonia emission inventory of Hebei Province was established using the emission factor method.The spatial distribution characteristics of ammonia emissions and emission intensity were studied by ArcGIS software.The anthropogenic ammonia emissions in 2019 of Hebei Province were up to 767.52 kt,of which the agricultural sources ammonia accounted for 93.17%.This result is mainly attributed to the lack of effective treatment of fertilizers and manure agricultural.The breeding of livestock and poultry and the application of chemical fertilizer were main emission sources,accounting for 69.59%and 21.19%of the total ammonia emissions,respectively.Meat poultry had the highest contribution to NH3 with a sharing rate of 37.04%.For the non-agricultural sources,human and fuel combustion emissions had higher contributions with contribution rates of 2.03%and 2.28%,respectively.An average emission intensity in 2019 of Hebei Province was 4.10 t·km-2,of which Shijiazhuang had the highest ammonia emissions and emission intensity with averages of 116.73 kt and 8.03 t·km-2,respectively.The areas with higher ammonia emission and emission intensity mainly concentrated in the southern and central regions of Hebei Province.
