Pathways, Processes and Driving Forces Chimney Effect (Stack Effect) Process whereby warmer air rises in buildings to upper levels and is replaced in the lower portion of the building by outdoor air drawn through a variety of openings, such as windows doors or cracks in the foundation or walls Botkin and Keller Environmental Science 5e

Sick Building Syndrome A condition associated with an indoor environment that appears to be unhealthy The symptoms people report cannot be traced to any one particular cause Botkin and Keller Environmental Science 5e

Environmental Tobacco Smoke Secondhand smoke 2 sources Smoke exhaled by smokers Smoke emitted from burning tobacco The most hazardous indoor pollutant Botkin and Keller Environmental Science 5e

Environmental Science 5e Radon Gas Radon Naturally occurring radioactive gas Colorless, odorless, tasteless Only identified through proper testing Health hazard when leaked into homes Exposure is associated with lung cancer Botkin and Keller Environmental Science 5e
