1农业氨减排对大气PM_(2.5)污染治理日趋重要显示文摘在新冠肺炎疫情期间,中国采取的管制封锁措施大幅减少了交通和工业排放,但农业排放没有受到影响,甚至有所增加.通过全国大气氨浓度地面监测、实时连续观测和卫星观测等手段,我们发现,新冠肺炎疫情管制措施实施期间中国大气氨浓度大范围显著增加,上升幅度在农村地区最为明显(增加22%),在城市和偏远地区变化不明显;而且,管控期间大气氨浓度上升幅度与2015~2019年相同月份相比更大.基于大气化学模式模拟发现,中国北方大气氨浓度上升主要是由农业氨排放增加所致.随着未来我国二氧化硫和氮氧化物等酸性气体排放控制的强化,农业氨排放的协同减排对于进一步削减大气PM污染、提升空气质量尤为重要.进一步分析表明,疫情期间50%农业氨排放可有效抵消氨浓度上升造成的二次无机气溶胶的形成.许稳 赵园红 温章 常运华 潘月鹏 孙业乐 马昕 沙志鹏 李紫玥 康嘉慧 刘磊 唐傲寒 王锴 张颖 郭怡鑫 张霖 盛立芳 张秀明 谷保静 宋宇 Martin Van Damme Lieven Clarisse Pierre-Francois Coheur Jeffrey L.Collett Jr Keith Goulding 张福锁 贺克斌 刘学军 2022Science Bulletin2022,67,17:2
