INTRODUCTION The effect of sink effect of volatile organic compounds in indoor air concentration modeling is necessary from former studies. There are several studies on sink effect of volatile organic compounds. However all of those studies only discuss on short term such as a few hours to a couple of days. The life of buildings or residences last for years, but there is no study concerning these period when figuring indoor air concentration modeling. The purpose of this study is to propose a protocol of modeling for a long-term indoor air concentration.METHODS The sink effect of 4 kinds of volatile organic compounds was examined. The specimen for building materials was a MDF board preserved in a controlled condition for 1 year. Also the effect of active carbon as an absorber was examined.RESULTS The results as follows were found through this study ;Sink effect is affective to the temperature and exposed concentration.An indoor air concentration model concerning on sink effect was proposed.The relation between the mass of adsorbent and the quantity of sink effect were in an exponential relation, however there was a point when of an adsorption equilibrium.

引言从以往的研究来看，挥发性有机物汇效应在室内空气浓度模拟中的作用是必要的。关于挥发性有机物的汇效应，目前已有一些研究。然而，所有这些研究都只讨论了短期，如几个小时到几天。建筑物或住宅的使用寿命通常长达数年，但在室内空气浓度建模时，还没有考虑这段时间的研究。本研究的目的是提出一个长期的室内空气中挥发性有机化合物浓度的模拟协议。建筑材料的样本是在受控条件下保存1年的纸板。结果研究发现：“汇效应”与温度和暴露浓度有关，提出了考虑“汇效应”的室内空气浓度模型，吸附剂质量与“汇效应”量呈指数关系，但存在吸附平衡点。
