Abstract

We have measured emission rates(ER) of DEHP from the PVC wallpaper using Micro chamber method when changing the environmental factors (Direction of a test sample, time and supplied gas type, test temperature). As a result, it was found that ER of DEHP is influenced by direction of a test sample and significant increased with the rise of test temperature. Additionally, we studied on the measurement of compounds other than DEHP, such as pesticides or phosphoric acid ester using Micro chamber method. The study conclusion indicated that it is possible to measure ER of pesticides or phosphoric acid ester from building materials.
