The materials found in our homes, factories, and offices, while seeming ordinary and commonplace, can contribute to the degradation of an often overlooked environmental measure: Indoor Air Quality. Compounded by ever more stringent energy conservation measures which can limit the ventilation in these spaces, the air we breathe indoors can pose threats to us now undreamt of in the days of draftier buildings.
Sources can be external or internal, biological or chemical in nature. External chemical ones include industrial and construction sources; exhausts from heating, ventilation, and air conditioning (HVAC) equipment and autos; radon, and other soil gases; pesticides and fertilizers. External biological contaminants can come from standing water which promotes mold growth.
