External Causes of Deterioration to Paper
Atmospheric pollution can be a cause of damage.
Calcium carbonate is added when making the paper. This is to give it a buffering to combat acids present in the air from pollution. Atmospheric pollutions are more commonly an issue in major cities.The paper would become acidic after it came into contact with atmospheric pollutants. So with the alkaline buffering it shouldn’t become acidic and degrade.
