Dr Ivana Fenoglio
Department of Inorganic Chemistry
Ivana Fenoglio is an expert on the surface reactivity of inorganic particulates including asbestos and silica polymorphs. Recently, part of its research has been devoted to the study of the mechanisms of toxicity of nanoparticles. Claire Horwell has collaborated with Ivana Fenoglio and Bice Fubini's group to study, for the first time, the generation of free and surface radicals from volcanic ash.

Download our pamphlets on preparing for ashfall and on the health hazards of ash. They are designed for mass distribution at the onset of new eruptions. They are now avaiable in English, Japanese, French Spanish, Portuguese, Swahili, Indonesian and Icelandic with Italian versions being available shortly. Please see our Pamphlets page for further infomation.
FACE MASK USE
IVHHN has an article under the Guidelines tab which used to be called 'Recommended Face Masks'. This has now been updated to 'Information on face masks' and is an interim page whilst the Health Interventions in Volcanic Eruptions project investigates which types of respiratory protection are effective in protecting the general population from volcanic ash inhalation. Please note that the translations in Spanish, Japanese and Portuguese have not yet been updated.
