The effect of atmospheric pollutants on paper permanence: A literature review

The literature on the influence of atmospheric pollutants on paper permanence shows that the absorption of sulfur dioxide by paper depends on many factors. There is limited work on the effect of nitrogen dioxide on paper permanence. No data exists on the effect of ozone. Work on mixtures of gases is scarce. There is almost no literature on the relationship between the amount of pollutant gas absorbed and the strength loss of paper.
