With the quantity of rice and rice-based foodstuffs imported into the EU growing each year, correctly distinguishing and quantifying highly toxic inorganic arsenic compounds from less harmful arsenic species that may be present in these imports has become increasingly important. In recognition of this, in June 2015 the European Union added inorganic arsenic to its regulations for setting maximum levels in a range of rice-based products. To meet the demands of the new regulations, arsenic speciation using ICP-MS interfaced with either an ion chromatography (IC) or liquid chromatography (LC) system is required. Ion chromatography is a particularly effective technique for this analysis, because of its high selectivity and sensitive detection capability. In addition to its speciation capabilities when coupled with IC, ICP-MS by itself is an effective tool for quantifying total arsenic concentrations in oxidized or digested food samples.
You will learn about the recent EU regulations regarding arsenic in rice based foodstuffs, the latest developments in arsenic speciation using IC-ICP-MS and the performance of ICP-MS for total arsenic measurement in a selection of food and beverage samples.
Dr Antonio Signes-Pastor Queen’s University, Belfast, UK
Dr. Antonio Signes is a Marie Curie Post-Doctoral Research Fellow at the Institute for Global Food Security – QUB. His research focuses on arsenic soil-plant transfer and distribution in the food chain, and human exposure. The usage of state-of-the-art analytical techniques, such as IC-ICP-MS, to carry out arsenic speciation in different biological matrices is crucial in his research. Dr. Antonio Signes has published several publications in the area food science, analytical chemistry, environment, and agricultural sciences.
