Abstract |
Consumer fireworks are a heterogeneous group of pyrotechnic items widely used by citizens around the world. There is a wide number of forensic cases related to consumer fireworks that requires knowing their chemical composition and variety of designs to conduct accurate and comprehensive analyses. In this research paper, a selection of six consumer firework types (firecracker, rocket, pyrotechnic fountain, pyrotechnic battery, sparkler and smoke bomb) is physically described and their anionic compositions are determined. Pre-blast (fuses and charges) samples and post-blast residues of the different consumer fireworks were analyzed by CE in order to determine their anionic composition. Different types of chemical compositions in fuses and pyrotechnic charges were determined, although they were not related to any type of item. Additionally, several discrepancies were found between the analytical results and the declared item compositions. Regarding post-blast residues, a huge variety of anions were identified and attributed to some unconsumed starting materials and different chemical reactions occurring during combustion.
