Sulfur dioxide is a major air pollutant that reacts with moisture to form sulfuric acid, which can corrode metal and stone sculptures.

Oxygen is not an indoor air pollutant, as it is essential for human life.

Air pollution damage refers specifically to the deterioration of cultural heritage materials caused by air pollutants.

Cleaning products, building materials, and pest control treatments can all release harmful chemicals into the air, contributing to indoor air pollution in museums.

A relative humidity level of 40-50% is generally recommended for the preservation of most museum objects, as it helps to prevent damage caused by excessive moisture or dryness.

Ultraviolet radiation is not an air pollutant, but it can contribute to the deterioration of cultural heritage materials by causing fading and embrittlement.

Air filtration, air purification, and air scrubbing are all processes used to remove air pollutants from the air.

Humidification is not a common method for controlling indoor air pollution in museums, as it can lead to increased moisture levels, which can damage museum objects.

Air quality monitoring, environmental monitoring, and climate control are all terms used to describe the process of monitoring air quality in a museum.

Catalytic converters are not commonly used in museums for air pollution control, as they are primarily used to reduce emissions from vehicles.

Air pollution impact assessment, environmental impact assessment, and risk assessment are all terms used to describe the process of assessing the impact of air pollution on cultural heritage materials.

Soiling is not a common type of air pollution damage to cultural heritage materials, as it is primarily caused by dirt and dust, rather than air pollutants.

Air pollution mitigation, environmental management, and risk management are all terms used to describe the process of developing and implementing strategies to reduce air pollution damage to cultural heritage materials.

Wind speed and direction sensors are not commonly used in museums for air pollution monitoring, as they are primarily used for weather monitoring.

Air quality education, environmental education, and public outreach are all terms used to describe the process of raising awareness about the importance of air quality for the preservation of cultural heritage.
