Indoor air quality in the Lithuanian Theatre, Music and Cinema Museum. Environmental monitoring and air quality assessment.

The report summarizes the main results obtained in the project “Environmental monitoring and air quality assessment in the Lithuanian Theatre, Music and Cinema Museum” funded by the Norwegian Financial Mechanism (EEA-Grants –Norway Grants). The main goal of the project was to assess the indoor air quality for the preservation of cultural heritage objects both in storage and exhibition. Measurements of environmental parameters were performed in different types of indoor locations and following different methodologies. High concentration of organic acids (acetic and formic acids) was measured in a storeroom with significant source of organic compounds, whereas high concentration ofNO2was measured in exhibition areas. The results indicated high infiltration of pollutants such as NO2and particles through the building envelope.
