Aerosol exposure system and time course in the mass deposition of aerosolized biocides: (a) Schematic representation and (b) photo of aerosol application. Aerosol exposure occurs in the middle of the chamber. The tissue inserts are housed in a tissue tray prefilled with culture media during exposure. (c) The time course in the mass deposition of aerosolized biocides. Data show mean mass deposited during exposure time (mean ± SD, n = 4). Biocides at other concentrations also showed similar trends (data not shown).
