尽管众所周知，建筑材料的吸附可能会显著改变污染物扩散的动力学，并且在某些情况下可能会完全主导污染物扩散，但很少有室内空气品质模型成功地将吸附效应纳入考虑范围。需要模型来解释不同类型建筑材料在不同环境参数下的吸附机制。此外，吸附可能会对室内挥发性有机物的传输、个人暴露、通风策略和建筑能耗产生重大影响。本研究项目的最终目标是获得一个有用、可靠且可能简单的建筑材料VOC吸附模型，该模型可用于室内空气品质设计。鉴于已经进行了大量调查，并在文献中公布了相应的结果，项目第一阶段的目标如下: 1） 进行文献综述；2） 获得可靠的实验数据，用于模拟不同环境条件下的吸附，如温度、相对湿度和空气流速；3） 评估室内空气品质设计中现有吸附模型的适用性，并建议是否有必要进行后续研究。主要研究人员:张建生，加拿大国家研究委员会主持:1999年4月至2001年7月，赞助:TC 4.10，室内环境建模，TC 2.3，气体空气污染物和气体污染物去除设备

Although it is well recognized that sorption by building materials has the potential to significantly alter the dynamics of contaminant dispersal and may, in some cases, completely dominate it, very few IAQ models have successfully incorporated the sorption effect into consideration. Models are needed which can to account for the sorption mechanisms of different types of building materials under different environmental parameters. In addition, sorption may have significant impact on the transport of VOCs indoors, personal exposures, ventilation strategy, and energy consumption in buildings. The ultimate objective of this research project is to obtain a useful, reliable, and possibly simple VOC sorption model for building materials that can be used for IAQ design. Given the fact that a considerable number of investigations have been conducted and the corresponding results have been published in the literature, Phase I of the project is aimed at the following:1) Conduct a literature review;2) Obtain reliable experimental data for modeling sorption under different environmental conditions, such as temperature, relative humidity, and air velocity;3) Evaluate the applicability of existing sorption models for IAQ design and recommend whether a subsequent phase of research is necessary.Principal Investigator: J.S.
