Indoor Air Quality (IAQ)
Indoor Air Quality (IAQ): Acceptable IAQ is air in which there are no known contaminants at harmful concentrations as determined by cognizant authorities & with which a substantial majority (80 percent or more) of the people exposed do not express dissatisfaction.
Indicator
Indicator: a number or ratio (a value on a scale of measurement) derived from a series of observed facts; can reveal relative changes as a function of time, a signal for attracting attention, (chemistry) a substance that changes color to indicate the presence of some ion or substance; can be used to indicate the completion of a chemical reaction or (in medicine) to test for a particular reaction.
