摘　　要：文章综述了中国2010-2020年气态亚硝酸(HONO)外场观测结果,按城市、城郊、乡村、其他等分析了HONO不同季节和地区浓度差异及原因。外场观测集中于京津冀地区、华东、华南等地。北京、石家庄、上海等地在观测期间发生了严重雾霾等污染事件,HONO浓度较高,其他城市测量结果相当。HONO平均浓度冬春季节高于夏秋季节,可能是冬春季容易发生雾霾污染,导致污染物浓度较高;城市地区高于城郊和乡村地区。高海拔地区、西北地区、室内HONO的观测研究较少,仍需大量研究。The achievements of field observations of gaseous nitrite from 2010 to 2020 in China were summarized, and the variation of HONO concentration in different seasons and regions, namely, urban, suburban and rural areas was analyzed,the cause of the variation was studied as well. The field observation were mainly carried out in Beijing-Tianjin-Hebei region, East China and South China. During the period of observation severe smog incidents took place in Beijing,Shijiazhuang and Shanghai, causing higher concentration of HONO being monitored. The mean concentrations of HONO in winter and spring were higher than in summer and autumn because the smog pollution more likely occured in winter and spring;on the other hand, HONO concentration was higher in urban areas than in suburban and rural areas. However,much more observation studies about HONO are yet expected in high-altitude and northwest areas, as well as in indoor environment, etc.
