首届湖南“旅发会”焰火燃放对空气质量的影响分析

Analysis of the Impact of Fireworks on the Environmental Air Quality in the First Hunan"Tourism Development Conference"

在分析环境空气自动监测站的24小时连续自动数据监测数据的基础上,研判得出首届湖南“旅发会”焰火燃放对张家界市环境空气质量产生影响,导致市电业局空气自动站PM_(10)、PM_(2.5)、NO_(2)浓度短时急剧升高,其中PM_(10)、PM_(2.5)浓度在焰火燃放1 h达到峰值,随后浓度逐渐下降,NO_(2)浓度则在焰火燃放2 h后达到峰值,随后下降。充分反映焰火燃放对环境空气质量的影响范围和程度主要取决于烟花质量优劣、燃放区域布局、燃放时段控制以及气象因素影响。对于大气污染防治精细化管理提供科学指引,也为其他城市举行活动控制大气污染提供参考。

Based on the analysis of the 24-hour continuous automatic data monitoring data of the ambient air automatic monitoring station,this paper concludes that the fireworks display had an impact on the ambient air quality of Zhangjiajie City during the first Hunan“Tourism Development Conference”,which led to a sharp rise in the concentration of PM_(10),PM_(2.5)and NO_(2)in the air automatic monitoring station of the Municipal Electric Power Bureau for a short time.The concentration of PM_(10)and PM_(2.5)reached a peak after the fireworks display for 1h,and then the concentration gradually decreased.The concentration of NO_(2)reached its peak after 2 hours of fireworks,and then decreased slowly.The scope and extent of the impact of fireworks on the ambient air quality are fully reflected mainly by the quality of fireworks,the layout of fireworks,the control of fireworks time and the impact of meteorological factors.It provides scientific guidance for the refined management of air pollution prevention and control,and also provides reference for other cities to hold activities to control air pollution.
