Summary
Renovation activities release high levels of particulate matter and fungi, significantly degrading indoor air quality (IAQ). Strict controls are essential to prevent health issues and maintain safe environments.
Area of Science:
- Environmental Science
- Occupational Health
- Building Science
Background:
- Renovation projects can release significant amounts of airborne pollutants.
- Poor indoor air quality (IAQ) poses risks to occupants' health and comfort.
Purpose of the Study:
- To assess particulate matter and fungal contamination during building renovation.
- To evaluate the impact of renovation on indoor air quality (IAQ).
Main Methods:
- Air sampling and analysis for particulate matter concentration and composition (lead, sulfate, nitrate, chloride, ammonium).
- Fungal identification and enumeration in air and on suspended dust.
- Particle size distribution analysis.
Main Results:
- Suspended dust levels (6.1 mg m(-3)) greatly exceeded Egyptian indoor air limits (0.15 mg m(-3)).
- High concentrations of sulfate, chloride, and lead were detected in particulate matter.
- Common fungal genera like Aspergillus and Cladosporium were prevalent, with some species capable of deep lung penetration.
Conclusions:
- Renovation activities severely compromise indoor air quality (IAQ) through particulate matter and fungal release.
- Inadequate precautionary measures allow pollutants to spread to occupied areas, causing health problems.
- Careful planning and management of renovations are crucial to mitigate air quality degradation.
