根据我国的实际情况讨论了各种氨排放源的排放因子,计算了各种氨源的贡献,以动物的贡献最大,占52%。1993年我国氨的排放量为12Mt,排放量最大的是河南、山东和四川,排放密度最大的是上海。在北京、广西、广东、湖南、江西和山东测定了大气氨的浓度,北京大气氨浓度有明显的季节变化,春季平均为16μg/m3,夏季最高为41μg/m3,冬季只有32μg/m3。一般夜间氨的浓度高于白天。测定了氨的垂直分布,并计算了氨浓度的标高。
Based on the actual situation in our country, the emission factors of various ammonia sources were discussed. The contribution of various ammonia sources was calculated. The contribution of animals was the largest, accounting for 52%. In 1993, China’s ammonia emissions were 12 Mt. The largest emissions were from Henan, Shandong and Sichuan. The largest emission density was Shanghai. Atmospheric ammonia concentration was measured in Beijing, Guangxi, Guangdong, Hunan, Jiangxi and Shandong. Atmospheric ammonia concentration in Beijing showed significant seasonal changes with an average of 16 μg / m3 in spring, 41 μg / m3 in summer and only 3.2 μg / m3 in winter . The general concentration of ammonia at night is higher than during the daytime. The vertical distribution of ammonia was measured and the level of ammonia concentration was calculated.
