| 摘 要： | 为研究青奥会期间不同天气条件下水溶性离子粒径分布特征,使用β射线测尘仪、安德森9级采样器和IC型离子色谱分析仪对南京2014-08-06~2014-09-04的PM_(2.5)、水溶性离子进行观测分析.将观测期间划分为晴天、雨天和阴天这3种天气类型.PM_(2.5)在不同天气条件下的平均浓度为晴天阴天雨天.PM_(1.1)、PM_(1.1~2.1)和PM_(2.1~10)中水溶性离子的浓度均是晴天阴天雨天,且降雨过程对细粒子的去除作用更为明显.Ca~(2+)和Mg~(2+)谱分布类似,呈双峰分布,降雨对SO_4~(2-)和NH_4~+在0.65~1.1μm清除作用较强.不同天气条件下NO_3~-/SO_4~(2-)比值均小于1,雨天和阴天时的NO-3/SO_4~(2-)值高于晴天.3种天气条件下SOR和NOR的值均大于0.1,SO_2和NO_2发生不同程度的二次转化,大气中存在更多的二次颗粒物.
