Volatile organic compounds (VOCs) are carbon-based chemicals that evaporate into the air at room temperature. In museums, they can originate from paints, adhesives, plastics, textiles, wood products, cleaning agents, display materials, and even the objects themselves. Although many VOCs are present at very low concentrations, prolonged exposure can contribute to chemical deterioration, unpleasant odours, and risks for staff and visitors.Why VOCs Matter to CollectionsThe effect of a VOC depends on its chemical identity, concentration, exposure time, humidity, temperature, and the sensitivity of the material involved. Acidic compounds, including acetic and formic acids, can corrode metals and damage mineral-based materia ...
