Description

A gaseous, Aerosol, or Particulate contaminant. Pollutants are generated by natural and man-made sources, such as decomposition, abrasion, or combustion. Pollutants may be damaging or toxic to the environment, people, and materials. Currently the pollutants with the highest outdoor concentrations generally occur in big cities (Nitrogen oxides, hydrocarbons, Ozone, Carbon monoxide, particulates) or near smoke stacks (Sulfur dioxide, nitrogen oxides). Very dense (Haze, or combination of smoke and fog, is called smog. Indoor air pollutants (organic acids, aldehydes, hydrocarbons, ozone, particulates, etc) are emitted from construction materials (wood, insulation, carpets, paints), office machines (copiers, printers) or are transported inside from the outdoor environment. The concentration of air pollutants may be decreased by minimizing sources or by reacting or absorbing the pollutants from the air. Once inside a museum, pollutants can deposit and interact deleteriously with museum materials. Scavengers are used to minimize the concentration of air pollutants in contained spaces.

TABLE Gas-phase pollutants are Ozone, Hydrogen sulfide, Sulfur dioxide, Nitrogen oxides, Formaldehyde, Formic acid, and Acetic acid.
