Determination of Particulate Matter Emission Factors of Common Pyrotechnic Articles

The measurement of particulate matter (TSP, PM10, and PM2.5) emitted by pyrotechnic articles is described. For this purpose, for entertainment purposes category F2 (i. e. consumer fireworks according to European legislation) are examined exemplarily. aim was determine reliable emission factors (EF). Different types were used obtain a more representative database. Commonly analytical methods, like impactor technology, accompanied scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy better insight into the nature emissions. Specific determined each article. In absence activity rates, an average specific factor can be assess inventories. investigated 253 g PM10 per kg net explosive content (NEC) 200 PM2.5 NEC. highest found battery shot tubes, lowest fountain-like Furthermore, hypothesis assessed whether it makes difference data based on mixtures or articles. It demonstrated that combustion generates higher amount than mixtures.
