Abstract: Emission rate of bis (2-ethylhexyl) phthalate, DEHP, a SVOC (Semi Volatile Organic Compounds), contained in poly vinyl chloride (PVC) sheet as a plasticizer, was measured with passive gas flux sampling method. A gas sampler made of glass petri dish attached with a glass filter was placed on the surface of the PVS sheet for a given sampling time, and the component captured onto the glass filter was analyzed. The sampling temperature was 25℃ and 50℃, and the DEHP contents were changed in the range of 0.16% to 32.3%. The saturation concentration of DEHP at the surface of the PVC, C*, was determined based on the experimental results and the emission model considering the time lag before reaching the steady-state diffusion. The observed saturation concentration was in proportional to the DEHP content in the PVC sheet. The saturation concentration would give essential information for evaluating the personal exposures to DEHP.
