EXPERIENCES WITH PHOSPHINE-BASED FUMIGATION

IN MUSEUMS

KATALIN GHERDÁN

Since the phase out of the traditionally used methyl-bromide, stored product insects in large granaries and flour mills are usually fumigated with phosphine-based pesticides world-wide. This fumigation practice has also been applied by several museums in Hungary in the last decade. Investigating the catastrophic consequences of such a museum fumigation we made an experiment during the phosphine-based fumigation of the biological collections in a museum. Our aim was to get to know the reaction processes acting between copper-rich metal objects and phosphine. The results show that even if meteorological parameters are favourable and only minimal effective pesticide doses are used, phosphine causes corrosion of the metal surface, thus its application in the presence of cultural heritage objects is seriously contra-indicated.
