摘要

为研究烟花爆竹燃放对南昌市PM

2.5

的影响

2018年3月2—5日针对南昌市PM

2.5

质量浓度的变化趋势进行分析

同时结合单颗粒气溶胶飞行时间质谱仪对烟花爆竹燃放释放的颗粒物的质谱特征

对元宵节前后烟花爆竹源在PM

2.5

中的占比进行了评估。结果表明

3月2日夜间至3月3日凌晨时段的PM

2.5

质量浓度升高与烟花爆竹燃放有关;烟花爆竹源颗粒物占所有颗粒数的11.5%

3月3日日均占比最高为13.7%;烟花特征离子中

数浓度上升了约4.4倍

数浓度上升了约16.9倍

数浓度上升了约3.9倍;此外K

数浓度上升了约24.4倍。

Abstract

In order to study the impact of fireworks and firecrackers on PM

2.5

in Nanchang city

the trend of PM

2.5

mass concentration in Nanchang city was analyzed from March 2nd to 5th

2018

and the mass spectrometric characteristics of fireworks and firecrackers by using single particle aerosol time-of-flight mass spectrometer was used to were evaluate the proportion of fireworks and firecrackers in PM

2.5

before and after the Lantern Festival. The results showed that the increase of PM

2.5

mass concentration from the night of March 2nd to the early morning of M

arch 3rd may be related to the fireworks and firecrackers; the fireworks and firecracker source particles account for 11.5% of all the particles

and the daily average was 13.7% on March 3 which was the highest; in the characteristic ions of fireworks

the concentration of Al+increased by about 4.4 times

the concentration of Ba+increased by about 16.9 times

the concentration of Mg+ increased by about 3.9 times

and the concentration of K

increased by about 24.4 times.
