摘要：

硝酸(HNO3)、亚硝酸(HNO2)和氨气(NH3)是大气中重要的含氮化合物,不仅影响大气的光化学氧化能力和酸碱性,还在大气氮沉降中有重要贡献.利用2012年5月4—13日在青岛采集的denuder大气样品,分析了其中HNO3、HNO2和NH3的浓度.青岛大气中HNO3、HNO2和NH3浓度分别为0.88～6.15μg·m-3、0.07～2.02μg·m-3和0.47～7.87μg·m-3,平均分别为2.06μg·m-3、0.92μg·m-3和3.03μg·m-3.大气中3种气体浓度的昼夜变化均无显著性差异.平行采集的样品分析结果显示:denuder涂层的差异对HNO3和NH3的观测结果影响较小,但对HNO2的影响较大,且高温天气易于造成HNO2更大的观测误差.青岛大气中HNO3浓度与温度呈正相关、与湿度呈负相关关系,高温低湿天气时样品中HNO3的浓度一般较高,而高湿或降雨天气时的浓度则较低.NH3浓度与风向呈显著相关关系,主要受局地一次排放源的影响,NH4NO3和NH4NO2分解对青岛大气中NH3的贡献小于23%.青岛大气样品中NH3的浓度在阵雨时以受土壤释放的影响为主,浓度较高;而连续降雨时则以受湿清除作用的影响为主,浓度较低.
