Inorganic Arsenic Determination in Food: A Review of Analytical Proposals and Quality Assessment Over the Last Six Years

Here we review recent developments in analytical proposals for the assessment of inorganic arsenic (iAs) content in food products. Interest in the determination of iAs in products for human consumption such as food commodities, wine, and seaweed among others is fueled by the wide recognition of its toxic effects on humans, even at low concentrations. Currently, the need for robust and reliable analytical methods is recognized by various international safety and health agencies, and by organizations in charge of establishing acceptable tolerance levels of iAs in food. This review summarizes the state of the art of analytical methods while highlighting tools for the assessment of quality assessment of the results, such as the production and evaluation of certified reference materials (CRMs) and the availability of specific proficiency testing (PT) programmes. Because the number of studies dedicated to the subject of this review has increased considerably over recent years, the sources consulted and cited here are limited to those from 2010 to the end of 2015.

Nanomaterials, featuring with small size, easy preparation, high surface area and strong adsorption capacity, have become a kind of good adsorbents with extensive application potential for trace elements analysis and their speciation. Herein, the recent progress and advances in designing nanostructured solid phase extraction adsorbents based on various dimensions and their applications in trace elemental analysis and their speciation is reviewed, including zero dimensional nanomaterials (e.g. nanoparticles, mesoporous nanoparticles, magnetic nanoparticles, fullerenes), one dimensional nanomaterials (e.g. carbon nanotubes, inorganic nanotubes, nanowires), two dimensional nanomaterials (e.g. nanofibers, graphene/graphene oxide, layered double hydroxide) and three dimensional nanomaterials (e.g. nanoflowers, dendritic polymers). To further improve the selectivity, adsorption capacity and the application potential in direct sample analysis, some other novel nanometer materials, including ion imprinting materials, metal-organic frameworks and restricted access materials, are also developed and employed for the analysis of trace elements and their species in environmental and biological samples.
