Jörg Feldmann received his Ph.D. in Environmental Analytical Chemistry at University of Essen (Germany). He is the recipient of the Prize of the University of Essen and the Feodor Lynen Award (Alexander von Humboldt Foundation). After two years at the University of British Columbia (Canada), he became lecturer in 1997 at the University of Aberdeen (Scotland), where he progressed to a Chair in 2004. He is a member of the Environmental Chemistry Advisory Board and has published more than 100 scientific papers mainly on element speciation analysis in environmental and biological systems. The main focus of his research is on the use of hyphenated techniques for elemental and molecular mass spectrometry.

Pascal Salaün is an analytical and environmental chemist interested in the physico-chemical processes influencing the biogeochemical cycling of trace elements. He is specialised in the development of electrochemical sensors for the detection and speciation of metals and metalloids in natural systems. Currently, his research focuses on the use of solid microelectrodes, their application for on-site/in-situ monitoring and complexation studies together with the development of metallic nanostructures for electroanalytical purposes. He obtained a 5 years research fellowship in 2007 focusing on arsenic speciation in fresh/marine waters and in biological systems.

Enzo Lombi received a Ph.D. in agricultural chemistry from the Catholic University of Piacenza, Italy. He held positions at the University of Agricultural Science in Vienna, at Rothamsted Research (UK), at CSIRO Land and Water in Adelaide and at the University of Copenhagen. At present he is Associate Professor at the University of South Australia and is Leader of the Prevention Technology Program of the Cooperative Research Centre for Contamination Research and Remediation of the Environment. His major research focus is on the biogeochemistry of trace elements with a special interest on synchrotron-based techniques for the investigation of biological and soil processes.
