| 中文摘要: |
| 通过将上海虹桥机场2016年大气污染物监测数据与该市国控站点数据对比分析，结果表明：机场附近首要污染物为NO2和PM2.5，随着污染级别加重，PM2.5成为首要污染物的频次增加。虹桥机场NO2浓度均值在各季节均高于各国控站点，日变化呈“双峰双谷”特征，峰值出现时间较其他站点早1 h。冬季PM2.5浓度高于国控站点，其他三季相当。冬季PM2.5日变化具有明显的“双峰”特征，上午峰值出现时间较其他站点早一两小时，夏季不明显。O3日变化表现为上午其生成速率和NO2的消耗速率都要高于其他站点。 |
| 英文摘要: |
| The characteristics of air pollutants in Shanghai Hongqiao airport were analyzed by comparing the atmospheric pollutant monitoring data from the airport in 2016 with the data from the national monitoring stations in the city. The results showed that the main air pollutants in Hongqiao airport were NO2 and PM2.5. As the pollution level increased, the frequency of PM2.5 being the primary pollutant also increased. The mean of NO2 at Hongqiao airport was significantly higher than that from other monitoring stations in each season. The diurnal variation of NO2 had the characteristic of “double peaks and double valleys”. The peak time of NO2 appeared in the airport site was about 1 hour earlier than that from other sites. The concentration of PM2.5 in winter was significantly higher than that in other stations, but in other seasons, they were rather the same. The diurnal variation of PM2.5 had “double peaks” feature in winter, and the peak time appeared in the morning was 1 or 2 hours earlier than that in other stations. This situation didnt occurre in summer. The daily variation of O3 showed that its generation rate and NO2 consumption rate were both higher than that in other sites in the morning. |
