Although not a new phenomena, the biodeterioration of stones is made worse in recent times:
" 'One of the recent discoveries that is of concern is that increased air pollution can sometimes increase biodeterioration,' said Eric Doehne, a scientist at the Getty Conservation Institute."And sometimes, conservation treatment efforts unwittingly make things worse:
"Biodegradable polymers used to consolidate the stones of Mayan ruins in Mexico, for example, created conditions ripe for damaging microbes."Control measures that were mentioned, included specially formulated biocides, anoxic treatment using Argon gas and goof old-fashion regular maintenance.
