English Abstract The aim of this study was to ascertain the indoor air
quality of the libraries of the General Library of the Utrecht State
University. During two periods, one week in winter and one week in summer,
indoor and outdoor concentrations of the compounds sulphur dioxide (SO2),
nitrogen oxides (NO and NO2), ozone (O3) and black smoke were registered
continuously. The present study shows that the average concentrations
depend on the location. The concentrations of air pollutants are highest in
the Kelder, successively followed by the Handschriftenkluis, the Nieuwe
Magazijn and the Sing-Sing. It is probable that the distances between these
individual sections and the Wittevrouwenstraat, a narrow street with
relatively much traffic, play a role in this rank order. The measured
concentrations of air pollutants are low for all locations in comparison
with levels observed at archives and musea elsewhere, but are indeed above
the advised levels mentioned in the literature.
