花粉颗粒通过各种途径进入室内区域，对室内空气质量和人体健康产生负面影响。因此，对室内和室外花粉浓度进行测量，并研究影响室内外花粉浓度（I/O）比值的因素具有重要意义。在这里，我们回顾了花粉研究的最新进展，重点是对I/O比和影响因素的实验研究，并提出了进一步研究的途径。通过对108篇文献的检索，总结了花粉采样器的发展、基本原理、优缺点，并对影响花粉采样器I/O比的因素进行了归纳。结果表明，花粉类型、通风条件、室内观赏植物和人类活动等对I/O比值有显著影响，其变化范围主要在0 ~ 0.5之间。I/O比值在0.5 ~ 1及以上的花粉主要分布在15-30 μm的花粉中。垂直于主导室外风向打开的窗户和较大的窗户开口面积也增加了I/O比。室外花粉可以附着在人体表面，并通过人类活动进入房间，增加I/O比。本研究结果将有助于其他研究人员了解花粉I/O比的研究现状，并希望为未来的研究方向提供建议。
Pollen particles enter indoor areas through various routes, negatively affecting indoor air quality and human health. Therefore, it is important to measure the indoor and outdoor concentrations of pollen and to study the factors influencing the indoor/outdoor pollen concentration (I/O) ratio. Here, we review recent developments in pollen research, focusing on experimental studies on the I/O ratio and contributing factors, and suggest avenues for further research. Based on a literature search of 108 publications, the development, basic principles, advantages, and disadvantages of pollen samplers are summarized, and factors influencing the I/O ratio are summarized. The results showed that pollen type, ventilation, indoor ornamental plants, and human activities significantly affected the value of the I/O ratio, which mainly ranged from 0 to 0.5. Values of I/O ratio of 0.5–1 and higher were mainly found in studies with pollen diameters ranging from 15–30 μm. A window that opened perpendicular to the dominant outdoor wind direction and a larger window opening area also increased the I/O ratio. Outdoor pollen can adhere to human surfaces and enter a room through human activity, increasing the I/O ratio. The results of this study will help other researchers to understand the state of research on pollen I/O ratios and hopefully provide suggestions for future research directions.
