RIFM Is Testing New Software

June 7, 2012

An alternative method for assessing inhalation exposure.

The Research Institute for Fragrance Materials, Inc. (RIFM) is beta testing its innovative 2-Box Indoor Air Dispersion Model software, an alternative method for assessing inhalation exposure to fragrance materials. RIFM 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 at www.rifm.org.

The 2-Box Indoor Air Dispersion Model is a computational, indoor environment, air exposure model that characterizes the movement of a single chemical 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, which will be available soon, according to RIFM.
