The spray model is a higher tiered model within ConsExpo that describes the exposure to formed non-volatile aerosols. The spray model is an important model since the number of consumer spray products on the market is increasing. Key features of the spray model are the possibility to assume a cloud volume, inclusion of gravitational setting of aerosols, inclusion of particle size distributions and mass generation rates for a number of consumer spray products based on experiments, and the oral exposure following spraying.
New defaults have been derived for the spray model. The nwe defaults replace the old values, which are mentioned in the fact sheets.
