## Abstract

When analyzing personal exposure to indoor pollutants, mathematical estimates are often used. An important question is the effect that the spatial distribution of pollutant transport has on personal exposure. Indoor concentrations of pollutants, such as ozone, are controlled by transport and uptake at indoor surfaces. To estimate indoor exposures, the average flux to indoor surfaces may not be sufficient. Instead an accurate assessment of the spatial distribution of surface uptake may be necessary. Therefore, the research proposed is to measure and evaluate the spatial distribution of mass transfer to indoor surfaces, under controlled ventilations conditions, in a room sized chamber. Once the experimental data is collected we can then ask if the average mass transfer coefficient is appropriate in estimating indoor pollutant concentrations or is the spatial distribution of mass transfer needed.
