| 摘 要： | 针对暴雨对空气质量的影响的问题,结合葫芦岛市环境监测中心站2010年市区空气质量逐日监测资料与葫芦岛市气象局气象观测资料,采用空气污染指数和空气质量指数法,分析了葫芦岛市空气质量时间分布特征及其与暴雨的关系。结果表明,在影响葫芦岛市空气质量的主要3种污染物——二氧化硫(SO2)、二氧化氮(NO2)和可吸入颗粒物(PM10)中PM10为首要污染物;3种污染物变化趋势基本一致,都是夏季污染最轻,冬季污染最重,春秋两季居中;暴雨与污染物浓度变化有着密切的关系,4次暴雨过程所在日3种污染物浓度都较低,且在强降水过后第一天污染物浓度继续降低。

| Abstract: | Aiming at the problem of the impact of rainstorm on air quality,with the monitoring data of everyday air quality of Huludao Environmental Monitoring Center and Huludao Meteorological Bureau in 2010,the time distribution of the urban air quality and their relations with the rainstorm are studied by air pollution index and air quality index methods.Results indicate that the PM10 is the primary pollutant in those three matters(SO2,NO2 and PM10,which affect the urban air quality of Huludao).The change trends of the three pollutants are basically the same: summer pollution is the lightest;pollution in winter is the most;spring and autumn are in the middle.Rainstorm and pollutant concentrations have a close relationship,such as in the four days of rainstorm the concentrations of three pollutants are low,and in the first day after the rainstorm the concentrations continue to reduce. |
