Potentially harmful and toxic gases, and aerosols, were measured as well as sound pressures. Aerosols were measured with a Differential Mobility Analyzer (DMA) as well as a Laser Particle Counter. The focus was on particles with diameters between 11 nm and 20 µm. A transportable Fourier Transform Infrared (FTIR) spectroscopy detector registered the concentrations of emitted reaction gases, simultaneously. During the outdoor firework display, peak particle concentrations of >550000 particles cm-3, equivalent to a mass concentration of approximately 3.95 mg m-3, were detected, revealing a concentration maximum at approximately 175 nm particle diameter. The time-averaged particle mass concentration did not exceed 1.58 mg m-3 over 15 minutes. Due to the large distances (110 m) to the firing points, no significant harmful or toxic gas concentrations were measured during the entire firework display. In contrast, concentrations of sulphur dioxide (SO2) rose after an indoor firework display in a large event hall. On two days, more than 23000 particles cm-3 (which equates to a mass concentration of approximately 0.41 mg m-3) were detected when the hall ventilation was turned off, and more than 11000 particles cm-3 (which equates to a mass concentration of approximately 1.18 mg m-3) when the hall ventilation was activated. Concentration maxima appeared at approximately 300 nm particle diameter. The time-averaged particle concentrations in this case did not exceed 0.56 mg m-3 (over 15 minutes).

During these events, possibly harmful and toxic aerosol emissions were measured. Aerosols in the size range from 30 to 450 nm were detected. The maxima in the observed particle size distribution were between 80 and 175 nm, and the highest value determined was ~1.3 · 106 particles per cm³, while the highest mass concentration was approximately 1.8 mg m–3. The time-averaged particle mass concentration did, however, not exceed 0.7 mg m–3 (over 15 min).
