Abstract In Italy, aerobiological monitoring is usually carried out by the regional agencies for environmental protection (ARPA [Agenzia Regionale per la Protezione Ambientale]) using volumetric samplers. Another widespread method for the study of airborne pollen is the analysis of moss cushions, generally used to relate pollen rain to flora and vegetation. In this study, we compare the data coming from these two pollen monitoring methods: volumetric samplers and moss cushions. The study was carried out in the city of Florence (Italy) and took into consideration two different spans of time. The two pollen monitoring methods show quantitative and qualitative differences. The main discrepancy seems to be the direct consequence of the different preservation time of the grains in the moss cushions depending on the features of the pollen grains. The study also provides an estimate of the period of pollen accumulation and preservation in moss cushions, which turned out to be more than five years. The two sampling methods furnish complementary information; volumetric samplers especially suited for aerobiological studies and moss cushions for environmental and palaeobotanical research.

比较苔藓垫和体积采样器的花粉数据：佛罗伦萨市的研究（意大利）

摘要 在意大利，空气生物监测通常由区域环境保护机构 (ARPA [Agenzia Regionale per la Protezione Ambientale]) 使用容积采样器进行。研究空气传播花粉的另一种普遍方法是苔垫分析，通常用于将花粉雨与植物群和植被联系起来。在这项研究中，我们比较了来自这两种花粉监测方法的数据：体积采样器和苔藓垫。该研究在佛罗伦萨市（意大利）进行，并考虑了两个不同的时间跨度。两种花粉监测方法显示出定量和定性的差异。主要的差异似乎是根据花粉粒的特征，苔藓垫中的谷物保存时间不同的直接结果。该研究还提供了对花粉在苔藓垫中积累和保存的时间的估计，结果证明该时间超过五年。这两种抽样方法提供了补充信息；体积采样器特别适用于空气生物学研究和用于环境和古植物学研究的苔藓垫。
