Impact/Purpose:
Suspended and settled particles play an important role in indoor exposure to SVOCs. This paper describes a method for modeling the dynamic process of SVOC interactions with indoor particles. It is the first of its kind. Potential users include exposure modelers in OPPT, Regions, and NERL, as well as the research community outside EPA. It also supports the SHEDS-lite exposure models developed by NERL by serving as a front-end component. A Microsoft Windows-based computer program is being developed to implement this framework. This paper wraps up the development of the SVOC modeling framework, which is part of the FY-2013 deliverables for CSS 2.3, Task 2.3.1, Title (12): Simulation tools for modeling SVOC emissions and transport in buildings.
Description:
This paper describes a method for dynamic modeling of the interactions of semivolatile organic compounds (SVOCs) with airborne and settled particulate matter in the indoor environment. This method is fully compatible with the other components within the framework. Despite the uncertainties in some of the key parameters, the simulation results have revealed important information regarding the general behavior of SVOC-particle interactions and the role of particulate matter in human exposure to SVOCs.
