摘要

We assessed the levels and the composition of fungal particles including submicronic fragments and spores in indoor air of townhouse basements with mould problems. Fungal particles were detected using a novel immunodetection method with scanning electron microscope and the diversity of some selected mould species associated with damp buildings was assessed by qPCR. Preliminary results indicated dominance of fragments (62.8±44.1 ×10~3m~(-3) (71%)) including submicronic fragments (8.1 ±57.3 ×10~3m~(-3)) as compared to spores (18.1±8.6 ×10~3m~(-3) (29%)). Moreover, fewer fungal species associated with moisture damaged materials were detected in the outdoor (8 species) versus mouldy indoor (10 species). It is likely that the exposure to fungal aerosols in mouldy indoor is dominated by fragments. The indoor air was characterized by higher diversity of the selected mould species as compared to the outdoor air suggesting exposure to various fungal constituents.
