Comprehensive Guidance and Case Studies to Improve Indoor Air Quality

Bridging theory with real-world application, Indoor Aerosol Dynamics offers a comprehensive and systematic introduction to the behavior of airborne particles in indoor environments, delivering clear guidance and practical tools on a range of topics from fundamental mechanics to health impacts and engineering controls.

Readers will find information on indoor aerosol emission, movement, transformation, and removal, more specifically on indoor PM2.5, PM10, bioaerosols, pathogenic aerosols, secondary organic aerosols, aerosol generation, spatial transport, exposure, respiratory health, CFD simulation, multi-zone model, aerosol sampling and measurement, ventilation, filtration, disinfection, microbial inactivation, etc., enabling them to mitigate respiratory exposure and control infectious disease transmission. The book supports the development of elaborate measurement, sampling, monitoring, ventilation, filtration, and disinfection strategies, making it vital for applications in environmental health and engineering, building science, and public hygiene.

Discover information on: - Aerosol sources, transport modeling, exposure assessment, and infection transmission, with a focus on practical relevance
- Indoor aerosol behavior, including non-biological aerosols and bioaerosols, from emission and transport to health impacts and control strategies
- Health impacts of indoor aerosols from diverse sources—cooking, smoking, cleaning, lavatory use, and intrusion of outdoor aerosols
- Airborne infectious disease transmission including pathogenic aerosol shedding, exposure, symptoms, and risk evaluation
- Real-world case studies, data, problem sets, and other instructor materials for teaching and self-study

Essential for professionals working in the fields of public health, indoor air quality, ventilation, and indoor environmental systems, this book is also valuable for policy makers and regulators, and students in related programs of study.
