Abstract

Building materials, as a source of contaminant, such as volatile organic compounds (VOCs), and a sink of those pollutants, can significantly affect indoor air quality (IAQ). Physical models have been developed to predict volatile organic compound emissions from building materials. These results are helpful in adopting strategies to control the pollutant source. Therefore, experimental methods have been established for measuring input parameters to these models, such as diffusion coefficient (D), partition coefficients (K). However, currently available data of diffusion and partition coefficients are limited. Moreover, the effects caused by the physicochemical properties of VOC are not completely observed. Hence, it is requisite that a comprehensive investigation on the relationship between diffusion and partition coefficients, and the physicochemical properties of VOC be conducted. The twin chamber method was chosen in this research. The effects caused by physicochemical properties of VOC, such as molecular weight, vapor pressure, boiling point, and polarity, were investigated.
