Research Expertise

 

Pierre Delmelle's research interest lies in the environmental effects of volcanic emissions. Pierre uses a combination of field and lab measurements to better understand how volcanic gas and ash materials react once released into the environment. He applies surface science methodologies and techniques to examine the factors which govern the surface reactivity of volcanic ash. He also studies the geochemistry and fate of volcanogenic fluoride in different environmental media (air, ash, water, soil and vegetation). In addition, Pierre leads a research aimed at improving the monitoring and assessment of exposure to volcanogenic fluoride. With Julie Calkins (PhD Student) and colleagues from the Institute of Food Research, he is developing a protocol for evaluating the bioaccessibility of volcanogenic fluoride in ash, soil and food.

 

Pierre also works on the characterisation of volcanic ash leachates, the measurement of trace metals in volcanic aerosols, the transport and retention of volcanic fluoride in soils and the impact of volcanic acid and ash deposition on soil properties and functioning. Recently, he has been involved in the development of quantitative tools for informing the decision-making process in volcanic hazard management.

PAMPHLETS

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.
