Resumo(s)
While active microbial air sampling (e.g., MAS-100 impaction) is the regulatory gold standard for indoor air quality, its reliance on short-term, equipment-intensive sampling limits its scope. This study evaluates the complementary role of passive sampling, such as settled dust (SD), which integrates microbial deposition over time. We compared both methods within school classrooms (N=10) in a winter sampling campaign using culture-dependent methods for fungal and bacterial contamination. Although the active method provided load snapshots, SD allows a broader spectrum of microbial contamination and reflects cumulative exposure. Our results demonstrate that SD is not merely a low-cost alternative but a complement to active sampling. The reliance on active methods in current frameworks overlooks critical long-term exposure data. Consequently, passive sampling represents a complementary tool that could enhance future regulatory monitoring frameworks. Its consideration would contribute to a more comprehensive and practical approach to managing infection risks in indoor settings, such as schools.
