Indoor air quality (IAQ) is the air quality within buildings and structures.Poor indoor air quality due to indoor air pollution is known to affect the health, comfort, and well-being of building occupants.
Since the release of the initial 1989 study, titled A study of interior landscape plants for indoor air pollution abatement: An Interim Report, [6] further research has been done including a 1993 paper [7] and 1996 book [8] by B. C. Wolverton, the primary researcher on the original NASA study, that listed additional plants and focused on the removal of specific chemicals.

Air pollution is the presence of substances in the atmosphere that are harmful to humans and other living beings, or cause damage to the environment. Air pollution can be chemical, physical or biological. [1]
Various definitions of pollution exist, which may or may not recognize certain types, such as noise pollution or greenhouse gases.The United States Environmental Protection Administration defines pollution as "Any substances in water, soil, or air that degrade the natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard.
The greenhouse effect occurs when greenhouse gases in a planet's atmosphere insulate the planet from losing heat to space, raising its surface temperature. Surface heating can happen from an internal heat source (as in the case of Jupiter) or come from an external source, such as its host star.
The density of air or atmospheric density, denoted ρ, [1] is the mass per unit volume of Earth's atmosphere.Air density, like air pressure, decreases with increasing altitude.
Light pollution is the presence of anthropogenic artificial light in otherwise dark conditions. [12] [13] [14] [15]The term is most commonly used in relation to in the outdoor environment and surrounding, but is also used to refer to artificial light indoors.
