佛山市南海区2019年春节燃放烟花爆竹PM_(2.5)源解析分析
|
摘要
结合环境空气自动监测站的PM_(2.5)监测数据,利用源解析的方法分析了2019年春节期间佛山市南海区燃放烟花爆竹所产生废气在PM_(2.5)中的占比及其成份。结果表明:(1)除夕夜燃放烟花爆竹会使PM_(2.5)浓度快速上升;(2)2019年春节期间烟花源平均占比为6.1%,年初一和年初二占比为10%,源谱中Al~+、Ba~+、Fe~+、K_2Cl~+、Mg~+等特征成分颗粒数浓度均出现大幅上升,其中含Al~+和含Fe~+颗粒在峰值时段的数浓度分别达到7014个/h和3317个/h。
Combined with PM_(2.5) monitoring data from the environmental air monitoring station, the contribution ratio of waste gas from fireworks to PM_(2.5) and its components in nanhai district of foshan city during the Spring Festival in 2019 were analyzed by using the source apportionment method. The results showed that:(1) burning of fireworks on New Year's eve would caused the PM_(2.5) concentration to rise rapidly;(2) during the Spring Festival in 2019, the average proportion of fireworks source was 6.1 %, and the proportion on the first and second day of the New Year was 10 %. The concentration of particles of characteristic components such as Al~+, Ba~+, Fe~+, K_2Cl~+, and Mg~+ in the source spectrum increased significantly. The concentration of Al~+ and Fe~+ particles at peak periods reached 7,014/h and3,317/h.
