Pollen and fungal spores (aerospora) are major atmospheric bioaerosols for pollen allergy sufferers. Aerospora types and concentration vary seasonally, depending upon the flowering period and meteorological factors which are variable in different geographical regions. The aim of this study was to analyze a two-year record of aerospora from two locations (Epe and Ojo) in Lagos (Nigeria), from May 2014 to April 2016. Aerospora were monitored with a modified Tauber sampler. The residual solution was harvested monthly throughout the duration of the study and acetolyzed, and microscopic slides were prepared. Aerospora were analyzed with light and scanning electron microscopy (SEM). SEM studies were applied to reach a higher level of pollen identification. A plant enumeration was carried out in the surroundings of the sampling sites. The aerobiological study revealed seasonal distribution patterns of various aerospora. The highest total pollen counts for 2014–2015 and 2015–2016 were recorded in April–July for both sites while minima occurred in January–December. Pollen of Poaceae, Euphorbiaceae, Convolvulaceae, Cyperaceae was dominant. Other taxa include Borreria sp., Elaeis guineensis, Amaranthus sp., Tridax procumbens. Fungal spores showed a high recovery for the months April–August for Epe in 2014–2015 and 2015–2016. In Ojo, fungal spores were high in July–August for 2014–2015 and in April–August for 2015–2016. Common fungal spores include those of Alternaria, Nigrospora, and Curvularia. The relationship between the aerospora spectra and the vegetation at the study locations was qualitatively investigated. There is a need to further test the allergenicity of pollen of common plants in Nigeria to inform pollen-hypersensitive individuals.

花粉和真菌孢子（气孢）是花粉过敏患者的主要大气生物气溶胶。气孢菌种类和浓度随季节变化，取决于开花期和不同地理区域的气象因素。本研究的目的是分析 2014 年 5 月至 2016 年 4 月拉各斯（尼日利亚）两个地点（Epe 和 Ojo）的两年气孢菌记录。使用改良的 Tauber 采样器监测气孢菌。在整个研究期间每月收集残留溶液并进行乙酰水解，并制备显微载玻片。用光和扫描电子显微镜（SEM）分析气孢菌。应用扫描电镜研究以达到更高水平的花粉鉴定。在采样点周围进行了植物清点。空气生物学研究揭示了各种气孢菌的季节性分布模式。2014-2015年和2015-2016年两个站点的花粉总数最高，分别记录在4月至7月，而1月至12月则最低。禾本科、大戟科、旋花科、莎草科的花粉占优势。其他分类群包括Borreria sp., Elaeis guineensis , Amaranthus sp., Tridax procumbens。真菌孢子在 2014-2015 年和 2015-2016 年 4 月至 8 月期间对 Epe 显示出较高的恢复率。在 Ojo，2014-2015 年的 7-8 月和 2015-2016 年的 4-8 月真菌孢子很高。常见的真菌孢子包括链格孢属、黑孢属和弯孢属的孢子。定性研究了气孢菌谱与研究地点植被之间的关系。需要进一步测试尼日利亚常见植物花粉的致敏性，以告知花粉过敏个体。
