A one-year survey of mold growth inside twelve homes
Annals of Allergy
|January 1, 1976
Abstract:
A survey was performed of the mold flora in the air and on the surfaces inside twelve homes throughout four seasons. There were significant variations of the mold flora in homes associated with the outdoor spore count, various rooms, carpeting, central air-conditioning and pets. We conclude that homes may be a source of perennial mold exposure.
Insights
Indoor mold exposure can occur year-round. Mold levels inside homes vary based on outdoor spore counts, room type, carpeting, air conditioning, and pets.
Area of Science:
- Environmental microbiology
- Indoor air quality
- Mycology
Background:
- Indoor environments harbor diverse microbial communities.
- Understanding mold (fungal) presence is crucial for public health.
- Seasonal and environmental factors influence indoor mold dynamics.
Purpose of the Study:
- To survey the mold flora in indoor air and on surfaces.
- To investigate variations in mold presence across seasons and home environments.
- To identify factors associated with indoor mold prevalence.
Main Methods:
- Conducted a year-round survey of mold flora in twelve homes.
- Collected air and surface samples across different seasons.
- Analyzed mold populations in relation to environmental factors.
Main Results:
- Significant variations in mold flora were observed within homes.
- Mold levels correlated with outdoor spore counts.
- Factors such as room type, carpeting, central air-conditioning, and pets influenced mold distribution.
Conclusions:
- Homes can serve as a consistent source of mold exposure.
- Indoor mold exposure may be perennial, not just seasonal.
- Environmental and domestic factors significantly shape indoor fungal communities.
