A thunderstorm is a risk factor for severe respiratory allergy or asthma attacks in patients suffering from pollen/spore allergy. This study aimed to investigate the changes in the spectrum and quantity of pollen and fungal spores in the air of Bratislava during summer storms as well as the impact of selected environmental parameters on these changes. Pollen/spore samples were collected using a Burkard volumetric aerospore trap during summer 2016. To identify those types of pollen/spores that may harm human health during the storm episodes, we analysed how the concentration of individual bioparticles in the air changed during pre-storm/storm/post-storm periods. The effect of environmental variables on the concentration of selected pollen/spore types was evaluated through Spearman’s correlation analysis. The results of our study suggest that thunderstorm-related respiratory allergy symptoms in the study area may be caused by (1) spores of Myxomycetes, the airborne concentration of which increases due to an increase in wind speed during the pre-storm period; (2) ruptured pollen and Diatripaceae spores, the concentration of which increases due to increase in precipitation and relative air humidity, respectively, during the storm period; and (3) spores of Fusarium and Leptosphaeria, the concentration of which increases due to increase in precipitation and air temperature, respectively, during the post-storm period.

中欧布拉迪斯拉发的夏季风暴及其对空气中生物微粒的频谱和数量的影响。

雷暴是花粉/孢子过敏患者严重呼吸道过敏或哮喘发作的危险因素。这项研究旨在调查夏季暴风雨期间布拉迪斯拉发空气中花粉和真菌孢子的光谱和数量变化，以及选定的环境参数对这些变化的影响。在2016年夏季，使用Burkard体积式孢子捕获器收集了花粉/孢子样品。为确定在暴风雨期间可能危害人体健康的那些花粉/孢子类型，我们分析了暴风雨前空气中单个生物颗粒的浓度如何变化/暴风雨/暴风雨后时期。通过Spearman相关分析评估了环境变量对所选花粉/孢子浓度的影响。我们的研究结果表明，研究区域内与雷暴有关的呼吸道过敏症状可能是由（1）粘菌菌的孢子引起的，其空气中浓度由于暴风前期风速的增加而增加；（2）在暴风雨期间，花粉和杜鹃花科孢子破裂，其浓度分别由于降水和相对空气湿度的增加而增加；和（3）的孢子镰刀菌和隐球菌的浓度在暴风雨后分别由于降水和气温的升高而增加。
