Determination of lanthanides in food samples by ICP-MS after their initial preconcentration on functionalized mesoporous silica materials
Résumé
Lanthanides (Ln) are increasingly used due to their unique catalytic, magnetic, optical and chemical properties in various branches of clean energy, high technology, as well as in
agriculture and medicine. As a consequence, they enter the environment and are eventually taken up by living organisms from the atmosphere, water and soil. The growing number of "anthropogenic" Ln anomalies in various environmental compartments indicates that they have become newly emerging pollutants. Metals present in soil and surface waters are mostly taken up by plants, which can be hazardous both for the plant and plant consumers. Due to the fact that the mechanisms of environmental and human toxicity of lanthanides are still poorly understood and require further research, it becomes necessary to monitor Ln concentrations in various samples, including food
