Air pollution can damage heritage collections. This study examines the air quality performance in one store with mechanical ventilation and in another with semi-passive climate control. Air pollution was measured with passive diffusion samplers during summer and winter. The atmospheric corrosivity was determined gravimetrically using copper, zinc and lead coupons, and by a real-time electrical resistance monitor over one year. The concentration of outdoor-generated air pollution was low within both stores. The emission of formic acid and acetic acid from internal sources led to higher indoor concentrations. The total acid concentration was 15 µg m-3 in the store with mechanical ventilation and 97 µg m-3 in the store with semi-passive climate control. The indoor atmospheric corrosivity was determined as very low by both methods. The study demonstrated that stores using mechanical ventilation with air filtration and semi-passive climate control provide acceptable air quality for the preservation of heritage collections.
