2017年成都市春节期间烟花爆竹对空气质量的影响

The Impact of Fireworks on Air Quality During the Spring Festival in Chengdu of 2017

利用空气监测数据分析了2017年成都市春节期间在烟花爆竹燃放时段空气污染物的浓度变化过程及对空气质量的影响,发现烟花爆竹的燃放会导致大气中二氧化硫和颗粒物浓度急剧攀升,使环境空气质量在短时间内迅速变差。通过对比《成都市烟花爆竹燃放管理规定》实施前后春节期间的空气质量情况,发现2017年春节空气质量持续好转。

This study analyzed the variation of air pollutant concentrations of air pollutants and the impact on air quality in Chengdu during the Spring Festival while the fireworks and crackers set off in 2017. The results showed that fireworks will lead to a sharp increase of sulfur dioxide and particulate matter concentrations in the atmosphere,so that the ambient air quality became bad in a short time. By comparing the air quality of the Spring Festival before and after the implementation of the provisions of the regulations on the management of fireworks and firecrackers in Chengdu,found out that the air quality of Spring Festival in 2017 continued to be better.
