A Rapid and Simplified Method for Determining Ozone and Other Image Degradation Oxidants in Air

摘要

It is now well known that pictures stored in circulating air are subject to degrading oxidants, especially ozone, that attack the dyes or pigments present in the image. This new perception is the result of many field observations and the testing by many manufacturers to explain why accelerated tests on images were under predicting life expectancy. It is also well known that expansion of industrialization, on a global scale, the increased burning of fossil fuels and the proliferation of vehicles of transportation in many new countries that have advanced economically, are creating atmospheric pollution that results in marked increases in ozone and other related oxidants on a world wide scale. So much for our understanding of the causes; this has sparked a great interest in methods that can quickly monitor atmospheric conditions and determine changes that influence image degradation and may allow better quantification between cause and effect.
