Understanding Indoor Air Pollution: Impact, Causes, and Solutions

This lecture provides an insightful overview of indoor air pollution, its significant health impacts, and various pollutants of concern. Students will learn about ventilation's critical role in maintaining indoor air quality and explore the challenges posed by both residential and workplace environments. Topics include common pollutants like radon, VOCs, and mold, as well as regulatory measures by OSHA for workplace safety. By examining local and global contexts, we highlight the importance of creating healthier indoor spaces and the technologies available for air pollution control.
