Francisco Ardini received his Ph.D. degree in Chemical Sciences in 2012 and he is currently a Tenure-Track Assistant Professor in Analytical Chemistry at the Department of Chemistry and Industrial Chemistry of the University of Genoa (Italy). His research focuses on the study of trace elements and organometallic compounds in environmental matrices and the development of new analytical methods based on atomic spectrometry for their determination. In particular, he is involved in environmental studies carried out in Svalbard (Norwegian Arctic) and Antarctica.



Andrea Bazzano obtained a joint Ph.D. degree in Chemical Sciences from the University of Genoa (Italy) and the University of Ghent (Belgium) in 2016, working on lead and strontium isotope ratio determination by single- and multi-collector inductively coupled plasma mass spectrometry. He currently works in a regional Italian environmental protection agency as a technician. His research interests include trace analysis, isotope ratio determination and interpretation, and statistics.



Marco Grotti received his Ph.D. degree in Chemistry in 1996 and he is currently a Professor in Analytical Chemistry at the Department of Chemistry and Industrial Chemistry of the University of Genoa (Italy). His research interests comprise fundamental studies in atomic spectrometry, development of new analytical methods for elemental, isotopic and speciation analysis of environmental matrices and their application to the study of polar ecosystems. In the context of the polar research, he participated in seven expeditions to the Arctic and Antarctica.

Environmental context. Lead is a toxic trace element, widely distributed in the Arctic environment as the result of both natural and anthropogenic processes. High-precision measurements of lead’s isotopic composition are used to distinguish the possible sources and track the transport pathways of this toxic metal. These measurements can provide unique global information on the history and status of lead contamination.

Abstract. Published data of lead isotopic ratios in the Arctic environment have been gathered in a dataset file (available as supplementary material) and reviewed to summarise the main information obtained for the different environmental compartments (atmosphere, cryosphere, lithosphere, hydrosphere and biosphere). The analytical procedures applied to achieve the precise measurement of this important environmental proxy are also illustrated and discussed. Finally, a general overview of the sources of atmospheric lead across the Arctic is provided.
