For several years intensive research has been carried out with the aim of developing a database of the types and amounts of pollutants released from indoor materials to the indoor environment. The paper discusses in detail basic problems and challenges encountered when estimating the emissions of chemical compounds released from of indoor materials. Factors affecting the validity of data obtained by using two different types of analytical devices operating in a dynamic mode (the ex-situ methods) or passive mode (the in-situ methods) for collecting the analytes samples from the gaseous phase were discussed. The main advantages and important limitations of specific analytical devices and aspects of the morphology of the studied indoor material that may influence the type and amount of chemical compounds released into the air were also highlighted. Attention has also been drawn to challenges encountered when developing candidate reference materials dedicated for measuring emissions from indoor matrices.

与估算室内材料中有机化合物排放量相关的问题和挑战

多年来，已经进行了深入的研究，目的是建立一个从室内材料释放到室内环境的污染物的类型和数量的数据库。本文详细讨论了估算室内材料释放的化学化合物排放时遇到的基本问题和挑战。讨论了影响通过使用两种不同类型的分析设备以动态模式（异位方法）或被动模式（原位方法）操作从气相收集分析物样品而获得的数据的有效性的因素。还着重指出了特定分析设备的主要优点和重要局限以及所研究室内材料的形态方面可能会影响释放到空气中的化合物的类型和数量的方面。
