摘要
2017年春节期间,根据湖南省城市环境空气自动监测系统数据资料,全面分析了燃放烟花爆竹对湖南省空气质量的影响。结果表明:烟花爆竹的集中燃放会在短时间内造成严重的大气污染,14个城市在集中燃放日(大年初一)全部出现空气质量超标现象;燃放烟花爆竹对PM_(10)和PM2.5影响最为显著,其次是SO_2和CO,NO_2和O_3受影响程度相对最小。集中燃放烟花爆竹所引起的PM_(2.5)和PM_(10)浓度增幅较大,尤其是PM_(2.5)。气象条件也是影响春节期间空气质量的重要因素。
The impacts of setting off fireworks to air quality of Hunan Province were analyzed by using the data of air automatic monitoring system. The result showed that the fireworks resulted in severe air pollution in a short time. Air qualities of 14 cities all exceed the standard on the New Year’s Day. Setting off fireworks had a significant impact on PM10 and PM2.5,followed by SO2 and CO,and minimum effect on NO2 and O3 relatively. The hourly average concentration increases of PM10 and PM2.5 all could be influenced by setting of firecrackers,especially PM2.5. Weather conditions were also the key factors affecting the air quality during the Spring Festival.
