The identification of a model organism for investigations of fine dust deposits on moss leaflets was presented. An optical method with SEM enabled the quantitative detection of fine dust particles in two orders of magnitude. Selection criteria were developed with which further moss species can be identified in order to quantify the number of fine dust particles on moss surfaces using the presented method. Among the five moss species examined, B. rutabulum had proven to be the most suitable model organism for the method presented here. The number of fine dust particles on the moss surface of B. rutabulum was documented during 4 weeks of cultivation in the laboratory using SEM images and a counting method. The fine dust particles were recorded in the order of 10 μm–0.3 μm, divided into two size classes and counted. Under laboratory conditions, the number of particles of the fine fraction 2.4 μm–0.3 μm decreased significantly.

介绍了用于研究苔藓传单上的细尘沉积物的模式生物的鉴定。使用 SEM 的光学方法可以定量检测两个数量级的细尘颗粒。制定了选择标准，通过该标准可以识别更多的苔藓物种，以便使用所提出的方法量化苔藓表面上细尘粒的数量。在检查的五种苔藓中，B. rutabulum已被证明是最适合此处介绍的方法的模式生物。B. rutabulum苔藓表面的细尘粒数使用 SEM 图像和计数方法在实验室培养 4 周期间记录。细粉尘颗粒按 10 μm-0.3 μm 的数量级记录，分为两个大小等级并计数。在实验室条件下，2.4 μm-0.3 μm 的细小部分的颗粒数量显着减少。
