2018年春节期间燃放烟花爆竹对常州市PM_(2.5)的影响研究

Impact of PM_(2.5) in Changzhou City During Spring Festival Period of 2018

为了解2018春节期间烟花爆竹燃放对常州市PM_(2.5)中的影响,分析了常州市6个国控站点的大气在线监测数据。结果表明:春节期间烟花爆竹的燃放会直接增加常州市空气中PM_(2.5)的浓度,由于PM_(2.5)中组分SO_4^(2-)、K^+和Cl^-等浓度的增加,从而造成PM_(2.5)的短时污染过程。

To understand the impact of fireworks on the PM 2.5 in Changzhou during the Spring Festival period of 2018, this paper analyzes the data of the differences of six national control stations in Changzhou. The results show that the fireworks and firecrackers during the Spring Festival will directly increase the concentration of PM 2.5 .And the concentration of components such as SO4^ 2-, K^+ and Cl^- in PM 2.5 will increase, which will cause the short-term pollution process of PM 2.5 .
