Impact/Purpose:
The research was under CSS program. This SVOC research will help to characterize human exposure, develop and refine source-to-exposure-to-dose models, and develop strategies that enlighten risk assessments and policy decisions to minimize exposures of SVOCs and protect human health.
Description:
Semi-volatile organic compounds (SVOCs) have low emissions over a long period of time due to their low vapor pressure. Understanding the transport mechanisms of SVOCs between sources, air, house dust, and interior surfaces in the residential environment will help to characterize human exposure, develop and refine source-to-exposure-to-dose models, and develop strategies that enlighten risk assessments and policy decisions to minimize exposures and protect human health. To characterize the sink effect of SVOCs in the indoor environment, small chamber tests are often conducted. However, the adsorption of SVOCs by the chamber walls is significant. To overcome this experimental difficulty, a new chamber designed to measure the SVOC concentrations in the outlet air of the chamber and in the sink materials was fabricated and tested in the study.
