The eradication of parasites from cultural heritage assets can be
performed though the application of several methods: the ones based
on chemicals are dangerous for human health, pollute the environment
and can produce severe alteration to the collections.

Physical methods are much more suitable; among these, the most
effective and easy to be applied is the Anoxia (few weeks of
exposition to low oxygen concentration will kill the 100% of any
specie of parasite; eggs and larvae included).

The VELOXY system allows the application of anoxia also by the
personnel of the conservation structure: see
<URL:http://www.rgi-genova.it> . It was developed and tested in the
frame of the EU project SAVE ART and it has been applied in a number
of museums, archives and libraries (see references)
