DESCRIPTION: Pollutants can be of internal or external origin. External pollution can be from cars or generated from industry (emitting gases nearby); internal pollution may be present in cleaning products, building materials components, those of certain objects or equipment, and from the visitors themselves.
Pollutants may be transported by air, transferred by contact, they can be an integral part of the object or appear via degradation process happening within the object. The main pollutants are sulfur oxides (industry) and nitrogen (cars and industry). Then there is also hydrosulfuric acid, chlorine, soot, and dust.
Pollutants are chemical compounds that can be found in solid, liquid, and gas. They act with temperature, relative humidity, and light and may cause the degradation of organic and inorganic objects.

How can these agents be detected in indoor environments?
In order to find evidence of pollutants in the building or on the objects/collections we can use:
