How does pollutants affect art conservation?

Pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter can significantly degrade artworks and artifacts by causing chemical reactions that lead to corrosion, discoloration, and deterioration of materials such as paint, metals, and textiles. These pollutants can also create an acidic environment that accelerates the degradation process. Additionally, the presence of pollutants in museums and galleries can complicate conservation efforts, requiring more frequent cleaning and restoration work to maintain the integrity of the artwork. As a result, protecting artworks from environmental pollutants is a crucial aspect of art conservation.
