Abstract

The present study examines the emission levels of particulate matters (PM) from sparkling fireworks and to know the emission characteristics of PM. Particulate matter <2.5 microns (PM2.5) and suspended particulate matter (SPM) were determined while burning six brands of sparkling fireworks. The average PM concentrations before burning were levels of 10 μg/m 3 , but the average concentrations after burning were 741 μg/m 3 for PM2.5 and 810 μg/m 3 for SPM. The mean ratio of the concentrations of PM2.5 and SPM after burning in all of the sparkling fireworks was 0.890. The emissions per firework ranged from 6.5 mg to 151 mg for PM2.5, and from 7.1 mg to 160 mg for SPM. The means of the emissions per combustible amount of the firework ranged from 0.017 to 0.066 mg/mg for PM2.5, and from 0.018 to 0.071 mg/mg for SPM. The influences of the burning time, burning rate and combustible amount of the fireworks on the PM emissions were investigated. As a result, PM2.5 and SPM emissions tend to increase with the burning rates. This suggests that the burning rate of firework have an influence on the PM emissions.
从闪闪发光的烟花空气中的微粒物质
本研究通过对烟花燃放过程中颗粒物(PM)排放水平的检测,了解PM的排放特征。在燃烧6种品牌的烟花时,测量了<2.5微米(PM2.5)的颗粒物和悬浮颗粒物(SPM)。燃烧前PM的平均浓度为10 μg/ m3,燃烧后PM的平均浓度为741 μg/ m3, SPM的平均浓度为810 μg/ m3。所有烟花燃烧后PM2.5浓度与SPM浓度的平均比值为0.890。每个烟花的PM2.5排放量从6.5毫克到151毫克不等,SPM排放量从7.1毫克到160毫克不等。烟花每可燃量的排放平均值PM2.5为0.017 ~ 0.066 mg/mg, SPM为0.018 ~ 0.071 mg/mg。研究了烟花燃烧时间、燃烧速率和可燃量对PM排放的影响。PM2.5和SPM排放量随燃烧速率的增加而增加。这表明烟花的燃烧速度对PM的排放有影响。
