Abstract
Aerosol particles are one of the major pollutants in outdoor and indoor air. They may negatively influence health, but also have negative effects on ecosystems and cultural heritage.
Particulate matter (PM) can be harmful for works of art by causing soiling and chemical damage, depending on particle size and chemical composition. The aim of this study is to investigate concentrations and sources of airborne PM in the 2 types of indoor environment of the National Museum of the Czech Republic (the centre of Prague and a small town Terezin), and to establish the relationship between the indoor and outdoor environment.
