Metals exist in different chemical forms. These chemical forms allow understanding their properties and impacts to the environment, the living species and regulate their transfer between different compartments of the environment. To access this information, it is essential to develop new analytical tools to determine both the chemical species and have excellent sensitivities. This was accomplished by coupling techniques such as chromatography (liquid or gas) with different mass spectrometers after ionization by inductively coupled plasma.
The recent development of induced plasma spectrometers and multi-collection provides today a very high accuracy and high quality information on the chemical form; when this approach is added the isotopic signature this is currently totally innovative. We will develop analytical strategies performed in the laboratory and position their impact in understanding the cycle of metals in the environment or living with all the new issues it raises. Finally, implementation of Equipex MARSS will allow to significantly expand the understanding of the intimate structure of fields of matter as addressing the angle of visualization and localization of these phenomena in order to have a better understanding of the role of metals and metalloids in the environment and the living.
Olivier Donard is director of research at CNRS DRCE and is the director of the Institute for Analytical Sciences and Physical Chemistry for the Environment and Materials (IPREM in Pau). It is also the coordinator of the Equipex MARSS (Center of Mass Spectrometry for Reactivity and Speciation Sciences). He has always worked on the understanding of metal cycles in the environment and has opened new avenues for developing approaches to speciation and determination of chemical forms of these metals coupled methods. These advances are used to better understand the cycles of metals in the environment; Olivier Donard has conducted parallel research activities in the environmental sciences as in analytical sciences. He has published over 260 articles, and has received more than 150 invitations to give conferences abroad and was winner of several awards including the bronze medal of the CNRS and the price of the Analytical Chemistry Division of the Chemical Society of France CFS. Ihe has also created an analysis company Ultra Traces Aquitaine Analysis that has been fully operational since 1999.
