Museum objects require a certain kind of environment, which includes an atmosphere free of dust and pollutants. Unfortunately the outdoor air is often polluted. This is particularly the case in towns and industrial areas, where vehicles, heating systems and industry produce harmful pollutants.
This fact sheet from Museums Galleries Scotland describes basic types of air pollution: acidic and oxidising subtances; particulate pollutants, and how to protect museum collections from damage caused by them.
