Abstract
Abstract. This study investigated the effects of fireworks using aerosol optical depth (AOD) and aerosol optical properties (AOP) from Terra/Moderate Resolution Imaging Spectroradiometer (MODIS) and Sunphotometer, and PM (Particulate Matter) data were observed in Gwangju, South Korea and Shanghai, China. During the Lunar New Year period in 2014, the PM2.5 concentration by fireworks in Shanghai showed the highest concentration on the day of Lunar New Year, and air pollutants of long-range transport by fireworks were affected the increase of PM10 concentration and aerosol optical depth over the Korean peninsula). These results show that the effect of fireworks, which was recognized as a local air pollution problem, can be transported to the Korean peninsula from China. The results of this study can be very useful for monitoring the atmosphere by firework effect over the Korean Peninsula.
Highlights
Fireworks, which contain a large amount of heavy metals, increase air pollution. Berger et al, 1995 showed that Pb used an igniter to cause a flame explosion, Mn and Mn dioxide as fuel and oxidants for bright light, and Cr as a combustion rate catalyst for the propellant
Airborne pollutants caused by fireworks during the Chinese New Year period in China were transported over long distances and analyzed the PM data measured in Shanghai and Guangzhou, China
PM and satellite data in Shanghai, China where the pollutants are generated by fireworks every year and Gwangju, Korea area which is expected to be affected by the pollutants were used from January 28 to February 2, 2014 during the Lunar New Year
Summary
Fireworks, which contain a large amount of heavy metals, increase air pollution. Berger et al, 1995 showed that Pb used an igniter to cause a flame explosion, Mn and Mn dioxide as fuel and oxidants for bright light, and Cr as a combustion rate catalyst for the propellant. Fireworks, which contain a large amount of heavy metals, increase air pollution. Devara et al, 2015; Vyas and Saraswat, 2012 showed aerosol optical properties of fireworks and focused on regional atmospheric changes of pollutants from fireworks. It was not the spatial distribution of long-rage transported air pollutants In China, the New Year, which is January 1st of the lunar calendar, is called Lunar New Year. Airborne pollutants caused by fireworks during the Chinese New Year period in China were transported over long distances and analyzed the PM data measured in Shanghai and Guangzhou, China. The backward trajectory analysis was performed for a path of the long-ranged transport aerosol, and the satellite data was used to monitor the AOD (Aerosol Optical Depth) value
