RIFM Launches 2-Box Indoor Air Dispersion Model Beta Test
RIFM's innovative 2-Box Indoor Air Dispersion Model software, an alternative method for assessing inhalation exposure to fragrance materials is available from the RIFM Database. Database subscribers can download the model for individual use by selecting “Tools and Models” from the RIFM Database home page and then selecting the model for download. The RIFM Database can be accessed from the Database section of the RIFM Science area on this web site.
The 2-Box Indoor Air Dispersion Model is a computational, indoor environment, air exposure model that characterizes the movement of a single material inside two connected, enclosed rooms. The model allows the user to determine air concentrations, over time, to assess potential inhalation exposure for different air care products under defined conditions of consumer use. The 2-Box Air Dispersion Model has been instrumental to the Systemic Quantitative Risk Assessment (QRA) Task Force for the inhalation aspect of their analysis of exposure from dermal, oral, and inhalation routes, and for aggregate exposure.
The 2-Box Indoor Air Dispersion Model software functions independently but can be used in conjunction with the Multiple Path Particle Deposition (MPPD) Model. The MPPD Model will calculate material deposition in the upper and lower respiratory tract. Dr. Madhuri Singal, Manager, Respiratory Science at RIFM said, “We are proud to unveil the RIFM 2-Box Air Dispersion Model. A milestone for the Respiratory Science Program, this computational model is a great alternative risk assessment tool that will provide useful information for everyday inhalation exposure calculations. It is an important complement to the MPPD Model.”
Please send your feedback on the 2-Box Indoor Air Dispersion Model to Danielle Vitale, Respiratory Specialist, dvitale@rifm.org. It will help RIFM to refine and further enhance the software.
