To identify and registry the most important aeroallergens trapped at the aerobiology station in the city of Samborondon, Ecuador.
Pollen grains and fungal spore counts were performed according to the standardized technique with a Hirst-type collection equipment, Burkard spore trap for seven days, following the recommendations of the National Allergy Bureau (NAB) of the American Academy of Allergy Asthma and Immunology (AAAAI). The equipment was installed on the roof of the Universidad de Especialidades Espiritu Santo (UEES), 25 m above ground level, coordinates: 2°07 ́57 ́ ́S 79°52 ́06 ́ ́W, in the city of Samborondon. The sampling period was performed from November 2022 to April 2023.
We identified the following pollen families: Poaceae (258 grains/m3), Apocynaceae (Plumeria rubra pc) (214 grains/m3), Lamiaceae (180 grains/m3), Asteraceae Ambrosía spp.- (60 grains/m3), Chenopodiacea (27 grains/m3), Myrtaceae (17 grains/m3), Pinaceae (11 grains/m3), Betulaceae (7 grains/m3). Also identified fungical spores: Fuzariella spp./Leptosphaeria spp. (1899/m3), Cladosporium spp. (1407/m3), Nigrospora spp. (1183/m3), Dreschlera/Helmintosporum spp. (329/m3), Alternaria spp. (98/m3), Pithomyces spp. (79/m3), Curvularia spp. (48/m3), Stemphylium spp. (46/m3).
We reported the first study of aerobiology (capture and identification of environmental pollens and fungi) in the city of Samborondon. The inhabitants of this area are exposed to different aeroallergens with a predominance of Poaceaes pollen and Fuzzariella spp./Leptosphaeria spp. spores. The identified allergens should be part of the usual allergy studies. The results of this first preliminary study should be compared with information from the forthcoming years, which will help to identify variations in the concentration of seasonal aeroallergens, annual fluctuations, and extend the traps to other parts of the city.
识别并记录厄瓜多尔桑博龙东市空气生物学监测站捕获的最重要的空气过敏原。
根据标准化技术，使用赫斯特型采集设备（伯卡德孢子捕捉器）进行花粉粒和真菌孢子计数，为期七天，遵循美国过敏、哮喘与免疫学会（AAAAI）国家过敏局（NAB）的建议。该设备安装在圣灵大学（UEES）屋顶，离地面25米，坐标：南纬2°07′57″，西经79°52′06″，位于桑博龙东市。采样期为2022年11月至2023年4月。
我们识别出以下花粉科：禾本科（258粒/立方米）、夹竹桃科（红花鸡蛋花）（214粒/立方米）、唇形科（180粒/立方米）、菊科豚草属（60粒/立方米）、藜科（27粒/立方米）、桃金娘科（17粒/立方米）、松科（11粒/立方米）、桦木科（7粒/立方米）。还识别出真菌孢子：镰孢菌属/小球腔菌属（1899/立方米）、枝孢属（1407/立方米）黑孢属（1183/立方米）、德氏霉属/长蠕孢属（329/立方米）、链格孢属（98/立方米）、皮生霉属（79/立方米）、弯孢属（48/立方米）、匐柄霉属（46/立方米）。
我们报告了桑博龙东市的首项空气生物学研究（环境花粉和真菌的捕获与识别）。该地区居民暴露于不同的空气过敏原中，以禾本科花粉和镰孢菌属/小球腔菌属孢子为主。已识别的过敏原应成为常规过敏研究的一部分。这项初步研究的结果应与未来几年的信息进行比较，这将有助于识别季节性空气过敏原浓度的变化、年度波动情况，并将监测范围扩展至该市其他地区。
