Impact/Purpose:
This presentation presents research on development of a small chamber SVOC test method to measure SVOC(Organophosphate flame retardants)sorption parameters.
Description:
The transport mechanisms of semivolatile organic compounds (SVOCs) between sources, air,house dust, and interior surfaces in the residential environment needs to be better understood in order to more accurately estimate indoor SVOC exposure and develop risk management strategies that protect human health. This study describes a new design to improve an existing small chamber testing method used to characterize the sink effect of SVOCs on materials. The sink effect of organophosphorus flame retardants on the stainless steel chamber is also reported. The data are used to evaluate the applicability of the Langmuir sorption model for SVOCs. This chamber method could be used to estimate the material/air partition coefficientsand solid-phase diffusion coefficients of SVOCs for sink materials in the future.
