Indoor Air Pollution

People are the main reason for the quality of the indoor environment they occupy and, above all, for the indoor air quality. They, with their decisions regarding the construction materials, the interior products, and the building systems (HVAC, water supply and sewerage, electrical) predetermine the presence of different pollutants in the indoor air. In addition to this, people deteriorate the quality of the air in the space they occupy (pollute the indoor air) by their presence, i.e. by the physiological processes taking place in their bodies, which are continuous (metabolism) and discrete (defecation and urination). People also pollute the indoor air through their actions: activities (cooking, bathing, cleaning, insect fighting, etc.) and habits (aromatization, smoking, etc.).

Internal contamination is due to the presence of higher concentrations of chemical species (e.g. carbon monoxide), physical processes or biological pollutants (e.g. dust mites) in the ambient air.
