To Do: Migrate


Air pollution has been responsible for increasing the rate of deterioration of many historically and culturally valuable monuments. This phenomena is not confined to the United States; churches, cathedrals, and monuments worldwide have sustained damage as a result of air pollutants.

Unfortunately, common building and sculpting materials such as limestone, marble, and bronze are among the most susceptible to attack by anthropogenic atmospheric pollutants. This project is intended to provide information that will assist efforts by many individuals and groups to preserve monuments that are vulnerable to air pollution damage.
