title: Are these liquids explosive? Forensic analysis of confiscated indoor fireworks.
abstract: Complete forensic analysis of several confiscated liquids and gels putatively used as firework components was achieved by combining Raman, FTIR spectroscopy, and scanning electron microscopy combined with energy-dispersive spectroscopy (SEM-EDS). The chemical composition of the liquids was consistent with their use as indoor fireworks. Alcohols (methanol and isopropyl alcohol) were used to solubilise compounds producing coloured flames. Boric acid, recently introduced in the list of Substances of Very High Concern (SVHC) for the REACH Regulation of the European Union, was found in one of the samples.
