Data represent 10³ particles cm⁻² of culture media.

Medians, 25th and 75th percentiles (in parentheses); K–W D Kruskal–Wallis test for the three fungal species. The post-hoc Wilcoxon rank sum test of differences between species for median numbers with A. fumigatus significantly higher than A. versicolor and P. chrysogenum. Significance level (p ≤ 0.017). S1: Single spores; Aggregates of 2 (S2), 3 (S3), 4 (S4) and ≥5 (S5) spores. SF: Submicronic fragments, LF1: 1–2 μm fragments, LF2: 2–3.5 μm fragments, and LF3: ≥ 3.5 μm fragments.
