Unfortunately, little information is available on the 'normal' air and water load of Aspergillus spores and their seasonal changes. We describe the air and water load of Aspergillus spores across the province of Madrid (Spain). We collected samples of air and water (332 samples of air and 148 of water) from selected points and taps (urban and rural environment) in summer, autumn, winter and spring. Temperature, wind speed and humidity at each point were obtained. We collected a total of 369 Aspergillus spp. isolates: 200 A. fumigatus, 94 A. niger, 40 A. flavus, 16 A. nidulans, two A. terreus, and 17 Aspergillus spp. We always found more isolates in the urban environment than in the rural environment (P=0.11). This was also true of A. fumigatus (P=0.014). The autumn collection yielded more isolates than that of the other seasons. The level of conidia in air varied from 0 to 85 c.f.u./m3: 6.4 c.f.u./m3 in summer, 12 in autumn, 2.5 in winter and 1.3 in spring. Changes in atmospheric parameters influenced the levels in air. None of the water samples were positive. Counts of Aspergillus spp. spores were always under 85 c.f.u./m3. Public water does not seem to contain Aspergillus spores.
遗憾的是，关于曲霉孢子的“正常”空气和水负载及其季节变化的信息很少。我们描述了西班牙马德里省曲霉孢子的空气和水负载情况。我们在夏季、秋季、冬季和春季从选定的地点和水龙头（城市和农村环境）采集了空气和水样（332份空气样本和148份水样）。获取了每个地点的温度、风速和湿度。我们共分离出369株曲霉属菌株：200株烟曲霉、94株黑曲霉、40株黄曲霉、16株构巢曲霉、2株土曲霉和17株其他曲霉属菌株。我们发现城市环境中的分离株总是比农村环境中的多（P = 0.11）。烟曲霉也是如此（P = 0.014）。秋季采集的分离株比其他季节的多。空气中分生孢子的水平在0至85 c.f.u./m³之间变化：夏季为6.4 c.f.u./m³，秋季为12 c.f.u./m³，冬季为2.5 c.f.u./m³，春季为1.3 c.f.u./m³。大气参数的变化影响了空气中的水平。所有水样均为阴性。曲霉属孢子计数始终低于85 c.f.u./m³。公共用水似乎不含曲霉孢子。
