Museums, historical buildings mainly located in urban centers, may be seriously affected by pollution and other critical urban atmospheric conditions. In addition to museums, there are many other different cultural heritage indoor environments each having different characteristics, mainly depending on the type of preserved materials that are sensitive to pollution and urban conditions. In this contribution we report an investigation of the indoor air quality and some considerations about the conservation of historical artifacts located inside the Historical Museum of Bersaglieri in Rome. Specifically, we show the feasibility in the exhibition rooms of a microclimatic characterization to evaluate the air quality, a critical issue for many of the artifacts exposed in confined spaces. The work we carried out is the monitoring of the behavior of temperature and relative humidity and the presence of airborne pollutants inside the museum halls. Taking into account the regulations in force that control and protect the Italian museums, these measurements have been carried out by using a customized and flexible system based on low-cost multi-parameter sensors allowing the monitoring of several environmental parameters. In spite of the limitation of this preliminary test study, on the basis of the results and according to the different preserved materials, a set of indications, criteria and tools have been provided to the museum managers to implement an effective "conservative strategy".

室内微气候调查和颗粒物检测：以罗马Bersaglieri历史博物馆为例

博物馆，主要位于城市中心的历史建筑可能会受到污染和其他重要城市大气条件的严重影响。除博物馆外，还有许多其他不同的文化遗产室内环境，每个环境都有不同的特征，主要取决于对污染和城市条件敏感的保存材料的类型。在此贡献中，我们报告了对室内空气质量的调查以及对位于Bersaglieri历史博物馆内的历史文物的保护的一些注意事项在罗马。具体来说，我们在展厅展示了微气候特征评估空气质量的可行性，这是暴露于密闭空间中许多文物的关键问题。我们执行的工作是监视博物馆大厅内温度和相对湿度的行为以及空气中污染物的存在。考虑到控制和保护意大利博物馆的现行法规，这些测量是通过使用基于低成本多参数传感器的定制且灵活的系统来进行的，从而可以监控多个环境参数。尽管该初步测试研究存在局限性，但根据结果并根据保存的不同材料，得出了一系列适应症，
