The research activity concerns the development of new analytical methods for elemental, isotopic and speciation analysis of trace elements and their application to environmental, biological and food samples. In particular, the research comprises fundamental and applicative issues related to the spectrochemical analysis of toxic and essential elements, the determination of their speciation and the precise measurement of lead and strontium isotopic ratios, as provenance tracers. The developed methods are mainly applied in the context of environmental studies in the polar regions, with the purpose of investigating the occurrence, potential sources and bioavailability of trace elements, in relation to natural processes and global climate changes. The research is carried out in the frame of national and European projects and involves renowned research groups.
New challenges… more research
In our fast-changing world, scientists are asked to provide the knowledge that is necessary to face worldwide problems, such as climate-related environmental changes, food security and traceability, emerging health threats, energy supply, and so on. In the effort of improving our knowledge of complex systems and to correctly drive the decisions of policy-makers, the obtaining of reliable, objective and reproducible scientific data is of primary importance. As the science of chemical measurements, the analytical chemistry plays a full role in the advancement of the scientific knowledge, offering instruments and methods to continuously give new answers to emerging questions. The activity of the research group is part of this mission, with specific focus on trace elements, their determination by atomic spectrometry and the investigation of their role in the environment.
This activity is briefly illustrated below via few, representative research topics we recently focus on. For a complete review of our studies, you are invited to check our List of publications.
Arsenic is not so bad!
In common parlance, “arsenic” is synonymous with “poison” but, scientifically, this is not correct! In fact, arsenic may occur in several chemical compounds that show wide-ranging levels of toxicity, from highly-toxic to innocuous. Therefore, the identification and quantification of the chemical species of arsenic - a process called speciation analysis - is of great importance for the correct assessment of the quality/safety of a specific environment or food. Besides, arsenic speciation analysis can provide information on the natural transformation/accumulation of this trace element through the food chain and among various environmental compartments.In this context, our research has been aimed at developing new analytical methods for arsenic speciation analysis of environmental and food samples, and at investigating the natural occurrence, transformation and temporal trend of arsenic compounds in Antarctic biota.
The research is performed in co-operation with Prof. Kevin Francesconi (University of Graz).
Sample introduction: the Achilles' heel of atomic spectroscopy?
In atomic spectrometry, it was immediately recognized that the sample introduction system largely determines the quality of the analysis, in terms of accuracy and sensitivity. Therefore, a lot of fundamental and technological research has been carried out in order to develop new systems, able to efficiently introduce any kind of sample into the atomization source, with limited matrix effects.
In co-operation with Prof. Jean-Michel Mermet and Prof. José Luís Todolí, we developed an innovative system, called heated torch-integrated sample introduction system (hTISIS), which proved to provide superior performances for the elemental and isotopic analysis of micro-samples by plasma-source atomic spectrometry. Applications of hTISIS comprised environmental samples (seawater, marine sediments, organisms, Antarctic snow), foods (vegetables, wine), biological tissues (human blood, bone tissue, cerebrospinal fluid) and organics (petroleum products and biofuels).
From trace to tracer
In many environmental studies, the determination of trace elements and their isotopic composition can provide valuable information on the geographical sources of both natural and anthropogenic inputs, the relative contributions of these sources over time and the corresponding transport routes. Recently, we developed new analytical methods for the precise measurement of lead and strontium isotopic ratios in challenging environmental matrices, using single- and multi-collector inductively coupled plasma mass spectrometry. The methods were validated and extensively applied to the isotopic analysis of atmospheric particulate and surface snow collected in the Arctic and Antarctica, in the context of RIS (Research in Svalbard) and PNRA (Italian National Program of Research in Antarctica) projects.
The research is performed in co-operation with Prof. Frank Vanhaecke (University of Ghent).
Iron is the key
Iron is an essential trace element involved in many biological processes, including photosynthesis and respiration. In vast areas of the Earth, it can limit the marine primary productivity, thereby controlling the biological carbon pump and the sequestration of CO2 from the atmosphere. Consequently, understanding the factors that control the iron availability in seawater and how they might evolve under a global warming scenario, becomes crucial to unravel how the climate system might develop in the next decades. With maximum extension of 18 million km2, sea ice constitutes the dominant and most widespread source of iron in polar waters during seasonal melting and therefore it may play a key role in drawing down atmospheric CO2 levels through the stimulation of primary production. In this context, our research has been aimed at investigating the factors that control the iron biogeochemistry in Antarctic coastal waters and in sea ice, through the application of suitable analytical protocols able to determine the organic speciation parameters.
The research is in co-operation with Dr. Delphine Lannuzel (University of Tasmania) and Prof. Paola Rivaro of the Chemical Oceanography group.
Starting from the fundamentals
In instrumental analytical chemistry, a thorough knowledge of the processes involved in the generation of the analytical signal is complex, but necessary to face practical analytical problems on a rational base. Therefore, despite the research in the atomic spectrometry field is becoming more and more application-oriented, fundamentals studies continues to be of great value. So, our group is also interested in fundamental studies concerning the atomic spectrometry techniques, including sample introduction processes, atomization and excitation mechanisms and matrix interferences.
