My current research focuses on consumers’ safety through several investigative streams: i) arsenic speciation in food matrices – which aims to expand the range of available certified reference materials for toxic arsenic species and to develop new methods for arseno-lipids quantitation, ii) metal contaminants in cannabis vape products – focusing on identifying sources of metals contamination in order to improve the safety of these products, and iii) bio-accessibility of metals – investigating the behaviour of dissolved and particulate metals upon their intake through the gastro-intestinal tract.
