The purpose of this study is to contribute to the knowledge about fungal spores in the atmosphere of the city of Salamanca (Middle West Spain), through the comparative study of Alternaria spore levels in two different sampling points within the same city. The study was done in terms of seasonal and hourly distribution and the possible influence of the main meteorological parameters on their atmospheric concentrations. The sampling was carried out from 17 February 2014 to 16 February 2016, both included, with two Hirst-type volumetric spore trap samplers, in two buildings in the city: one in a semi-urban environment, on the outskirts of the city, and the other in the city centre, 1.4 km apart. After the two years of sampling, the total annual values of Alternaria varied very little concerning the location of the samplers. The maximum values coincided in the two spore traps during 2014–2015 on the same day with similar amounts, whereas in 2015–2016 the difference was more noticeable both in date and amount. In the study of the seasonality of Alternaria's atmospheric distribution, there were no differences in the length of the main spore season nor the number of days with health risk levels (concentrations above 100 spores/m³). With regard to correlations, the analyses carried out between daily concentrations in both samplers obtained highly significant and positive results. The influence of meteorological parameters on spore levels, showed a positive effect of temperature and sunshine, as well as a negative one for humidity and rainfall.

本研究的目的是通过对同一城市内两个不同采样点的链格孢菌孢子水平的比较研究，为了解萨拉曼卡市（西班牙中西部）大气中的真菌孢子做出贡献。该研究是根据季节和小时分布以及主要气象参数对其大气浓度的可能影响进行的。采样时间为 2014 年 2 月 17 日至 2016 年 2 月 16 日，均包括两个 Hirst 型容积式孢子捕集器采样器，位于该市的两座建筑物中：一座位于城市郊区的半城市环境中，以及另一个在市中心，相距1.4公里。两年抽样后，交链格孢的年总价值采样器的位置变化很小。2014-2015 年两个孢子陷阱的最大值在同一天重合，数量相似，而在 2015-2016 年，日期和数量的差异更为明显。在对链格孢属大气分布季节性的研究中，主要孢子季节的长度和健康风险水平（浓度超过 100 个孢子/m ³）的天数没有差异。关于相关性，在两个采样器的每日浓度之间进行的分析获得了非常显着和积极的结果。气象参数对孢子水平的影响显示出温度和阳光的积极影响，以及湿度和降雨的消极影响。
