From: Estimation of the historical dry deposition of air pollution indoors to the monumental paintings by Edvard Munch in the University Aula, in Oslo, Norway

Fig. 6

Assessed indoor (a) and outdoor (b) [11] accumulated dry deposition (and not thus considering removal processes) of air pollutants to buildings in the urban background centrally in Oslo since 1835. The indoors is represented by the Munch paintings in the Oslo University Aula that were mounted in 1916. The ranges of the PM2.5 and O3 dry deposition represent the variation from estimates with the low to high values of the PM2.5 emissions factors [11] and I/O ratios, and O3 indoor deposition velocity (Table 2). The accumulated dry deposition and uncertainty ranges of PM2.5, and of O3 indoors, are reported from the middle of the displayed uncertainty ranges. Note the magnitude lower values of the indoor than outdoor dry deposition, and that the value of the indoor O3 deposition shown in the bar chart for 2020 is divided with 10
