Particle deposition indoors: a review

Area of Science:

• Environmental Health Sciences
• Indoor Air Quality
• Aerosol Science

Background:

• Increasing concern over human health effects of indoor particle exposure.
• Particle deposition indoors is beneficial as it prevents inhalation unless resuspended.
• Limited research on indoor particle deposition compared to deposition in small tubes.

Purpose of the Study:

• To provide an up-to-date review of experimental and modeling studies on indoor particle deposition.
• To summarize experimental studies on particle deposition in non-industrial indoor environments.
• To discuss mechanisms, experimental techniques, and modeling of indoor particle deposition.

Main Methods:

• Review of experimental studies on particle deposition in small chambers and real houses.
• Discussion of experimental techniques including particle generation, labeling, and detection.
• Inclusion of modeling aspects, specifically particle eddy diffusivity.

Main Results:

• Detailed experimental measurements from real house studies are presented.
• A survey of aerosol deposition experiments in various indoor settings is provided.
• Mechanisms of particle deposition relevant to indoor environments are outlined.

Conclusions:

• Particle deposition indoors is a critical factor for microcontamination control and human health.
• Further research is needed to bridge the gap between experimental findings and modeling efforts.
• This review serves as a comprehensive resource for understanding indoor particle deposition.
