An example of an integrated approach to assess air pollution threats to cultural heritage in a semi-confined environment is presented in this work, where the monitoring campaign carried out at the Michelozzo's Courtyard (in Palazzo Vecchio, Florence, Italy) is used as a case study. A wide research project was carried out, with the main aim of obtaining the first quantitative data on air quality and microclimate conditions inside the Courtyard, and, if possible, identifying the main causes of degradation and suggesting appropriate conservation strategies. The investigation adopted a holistic approach involving thermographic measurements on the wall paintings, microclimatic analysis, gaseous pollutant monitoring, atmospheric particles characterisation and dry deposition compositional analysis. Attention was focused on the wall painting depicting the city of Hall because of its anomalous and critical conservation conditions, which are visible at a glance, due to the contrast between a wide darker zone around the central subject of the painting and external lighter areas.
本工作提出了一种综合方法的范例，用于评估半封闭环境中空气污染对文化遗产的威胁，其中在米开罗佐庭院（意大利佛罗伦萨的旧宫）进行的监测活动被用作案例研究。进行了广泛的研究项目，主要目的是获得庭院内空气质量和小气候条件的第一批定量数据，并在可能的情况下确定退化的主要原因，并提出适当的保护策略。该调查采用了一种整体方法，包括对壁画进行热成像测量、微气候分析、气态污染物监测、大气颗粒特征分析和干沉降成分分析。由于壁画中央主题周围有一个宽大的较暗区域和外部较亮区域之间的对比，使得壁画描绘的城市哈尔的异常和关键保护条件一目了然，因此研究重点放在了该壁画上。
