This paper reviews vapor intrusion modeling studies published in the last decade (2010–2020). Compared to research carried out in the late 1990s and the early 2000s that was mainly focused on basic vapor transport phenomena and attenuation in the subsurface, the topics addressed in recent years focused on more complex scenarios, including the blocking effect of building footprint and surface pavements, soil and source heterogeneity, the role of capillary fringe, weather conditions such as rain, indoor–outdoor pressure differences, and temperature, building features, screening distances, and building pressure cycling. A brief description of these models and the main findings are reported in this paper. Generally, recent modeling works give more care about the influence of natural factors, which are relatively easy to be quantified and included in the model. Much less attention was given to factors involving human activities, such as preferential pathways, indoor environment structure, and background sources. The latter, however, may play a key role in determining the exposure to people of concern at sites contaminated by volatile contaminants. Thus, future modeling studies should be oriented to address these issues.

近期蒸汽入侵建模工作回顾

本文回顾了过去十年（2010-2020年）发布的蒸汽入侵建模研究。与1990年代末和2000年代初进行的研究主要集中于地下的基本蒸气传输现象和衰减相比，近年来解决的主题集中在更复杂的场景上，包括建筑足迹和地面路面的阻挡作用，土壤和源的非均质性，毛细条纹的作用，雨天等气候条件，室内外压力差以及温度，建筑物特征，筛分距离和建筑物压力循环。本文报告了这些模型的简要说明和主要发现。一般而言，最近的建模工作更加关注自然因素的影响，相对容易量化并包含在模型中。对涉及人类活动的因素的关注较少，例如优先通道，室内环境结构和背景来源。但是，后者可能在确定受挥发性污染物污染的场所暴露给关注人员方面起关键作用。因此，未来的建模研究应以解决这些问题为导向。
