Fifty ultra-sensitive pollution detectors with the capability of measuring temperature, humidity, pollution rate (with particular focus on carbon dioxide) and speed as well as direction of air flows, have been installed in the Sistine Chapel.
These sensors have been installed following the discover in July 2010 of a concentration of chemical particles in the walls of the chapel, capable of damaging the frescoes. Antonio Paolucci, director of the Vatican museums, formed an experts comité to debate the issue and find a way that will permit the visit by near 4 million people every year with the least damage as possible to the paintings.
The sensors have already supplied some clues, namely about the air conditioner installed in 1993 when of the restauration of Michelangelo's Last Judgement, which can be in part responsible for some air quality deficiency.
