初级生物气溶胶颗粒（PBAP），包括细菌、孢子和花粉，对于生物圈中生物和疾病的传播至关重要，大量研究表明它们可能对大气过程（包括云和降水的形成）很重要。然而，PBAP 的大气丰度和大小分布在很大程度上是未知的。在德国美因茨的一个城郊地区，我们使用紫外线空气动力粒径分析仪 (UV-APS) 来测量荧光生物气溶胶颗粒 (FBAP)，它提供了可行的生物气溶胶颗粒的估计值，并且可以被视为 PBAP 实际丰度的近似下限。非生物气溶胶成分的荧光可能会影响细颗粒物的测量结果（
Primary Biological Aerosol Particles (PBAPs), including bacteria, spores and pollen, are essential for the spread of organisms and disease in the biosphere, and numerous studies have suggested that they may be important for atmospheric processes, including the formation of clouds and precipitation. The atmospheric abundance and size distribution of PBAPs, however, are largely unknown. At a semi-urban site in Mainz, Germany we used an Ultraviolet Aerodynamic Particle Sizer (UV-APS) to measure Fluorescent Biological Aerosol Particles (FBAPs), which provide an estimate of viable bioaerosol particles and can be regarded as an approximate lower limit for the actual abundance of PBAPs. Fluorescence of non-biological aerosol components are likely to influence the measurement results obtained for fine particles (
