Abstract

Indoor and outdoor concentrations of photochemical pollutants and various trace species included nitrous and nitric acids were measured in the Uffizi Gallery, Florence. During the measurement period the indoor levels of ozone were typically 40% - 60% of those outdoors. The concentrations of HONO measured during the campaign ranged from 2.6 to 7.3 ppb whereas the concentrations of HNOs ranged from 0.02 to 0.7 ppb. NO% was measured by chemiluminescence and the results compared to those obtained by using a recently developed denuder technique. The study shows that chemical reactions occurring indoors are complex and can affect the distribution among indoor pollutant
