Atmospheric total suspended particulate (TSP) was passively sampled by means of deployed horizontal and vertical filters in various rooms of four Belgian cultural heritage buildings, installed with various heating/ventilation systems. Soiling/blackening and deposition of inorganic, water-soluble aerosol components were considered. The extent of soiling was determined by means of two independent methods: (1) in terms of the covering rate of the samplers by optical reflection microscopy and (2) the reduction in lightness of the samplers using the CIE Lab* color space by spectrophotometry. A fairly good correlation was found between both methods. The inorganic composition of the deposited water-soluble TSP was quantified by means of ion chromatography. Compared to controlled environments, uncontrolled environments showed increased water-soluble aerosol content of the total deposited mass. Higher chloride deposition was observed on horizontal surfaces, compared to vertical surfaces.
大气总悬浮颗粒物（TSP）通过在比利时四座文化遗产建筑的不同房间中部署的水平和垂直过滤器被动采集，这些建筑配备了各种加热/通风系统。考虑了污染/黑化和无机水溶性气溶胶成分的沉积。污染程度通过两种独立的方法来确定：（1）通过光学反射显微镜来评估采样器的覆盖率；（2）通过分光光度法使用 CIE Lab*颜色空间来评估采样器的明度降低。这两种方法之间存在相当好的相关性。通过离子色谱法对沉积的水溶性 TSP 的无机成分进行了定量分析。与受控环境相比，非控制环境中总沉积质量的水溶性气溶胶含量更高。与垂直表面相比，在水平表面观察到更高的氯化物沉积。
