Air pollutants cause negative effects on humans, wildlife and buildings. To control and reduce the impact of air pollutants, their transfer from sources to receptors needs to be known. This transfer includes transport within the atmospheric boundary layer, chemical transformation reactions and phase-transfer processes from gases to particles.

The air quality of both indoor and outdoor environments impacts the human health. Air pollution has been correlated to excess mortality and led to numerous air quality standards. This lecture covers indoor air pollutants, design of building air handling system, fundamentals of human respiratory system, toxicity and health impact of air pollutants, and personal protection.
