Seasonal dynamics of bacterial and fungal contamination in mechanical ventilation systems of a renovated university building

Puntos clave

• Bacterial and fungal contamination levels fluctuate with the seasons, indicating environmental impacts.
• In the study, fungal contamination peaked at 45% during spring and summer months, while bacterial levels reached 30%.
• Assessment across three different seasons highlights the need for regular maintenance in ventilation systems.
• Findings emphasize the importance of monitoring mechanical systems to mitigate contamination risks in indoor environments.
