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/m3, but the average concentrations after burning were 741 μg/m3 for PM2.5 and 810 μg/m3 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.
Highlights
Air pollution and its human health effects are of great concern to the general public
Several epidemiological studies have shown that an increase in airborne particulate matter (PM) is associated with respiratory symptoms, lung cancer, cardiovascular diseases and mortality (Ackermann-Liebrich et al 1997; Pope et al 2002; Du, Xu, Chu, Guo, & Wang, 2016)
suspended particulate matter (SPM) is defined as particles that pass through a size-selective inlet with a 100% efficiency cut-off at 10 μm aerodynamic diameter
Summary
Air pollution and its human health effects are of great concern to the general public. The problem of airborne particulate matter (PM) has received much recent attention. PM with a size of less than about 10 μm can settle in the bronchi and other parts of the lungs. These particles contain toxic heavy metals and hazardous organic pollutants (Bi, Sheng, Peng, Chen, & Fu, 2005; Vasilakos et al 2007). Several epidemiological studies have shown that an increase in airborne PM is associated with respiratory symptoms, lung cancer, cardiovascular diseases and mortality (Ackermann-Liebrich et al 1997; Pope et al 2002; Du, Xu, Chu, Guo, & Wang, 2016). International Agency for Research on Cancer (IARC) designates PM a Group 1 carcinogen (IARC, 2016)
