“…Among them, here we mention some reviews that are specifically dedicated to arsenic speciation with coupled techniques. 73,78,79,83,105,159 In addition, some more general reviews of analytical techniques include arsenic speciation. Some describe food samples or summarize such aspects as pre-treatment, extraction and preservation of the arsenic species, pre-concentration, how to overcome matrix interference, and specific instrumental conditions (such as types of nebulizers, the use of a dynamic reaction cell, and internal standards).…”

“…Chromatographic performance for arsenic species separation and interference with detection are discussed. Amaral et al 176 use a quadrupole-based ICPMS (ICP-QMS) in the coupled system and propose the use of 83 Kr þ instead of Ar for the interference standard method (ISM) to overcome the most common sources of interference that occur in Ar plasma. The system improved both the accuracy and sensitivity of arsenic species determination.…”

“…The analytical technology to be applied for the assessment of arsenic species, highlighting iAs, is continuously updated and reviewed. 43,[73][74][75][76][77][78][79][80][81][82][83][84] Nearing et al 85 reviewed additional analytical methods suitable for obtaining data to complement the information on arsenic speciation obtained when applying the methods commonly used. Among such complementary methods, electrospray mass spectrometry (ESI-MS) is most useful for identifying or complementing information on several arsenic compounds with more complex molecular structures than those corresponding to iAs species.…”

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.

“…The main concern about the determination of arsenic in environmental samples has been habitually related to its presence in groundwater [11,12], drinking water [9,13], biota [14], soils [15] and food [16]. However, air represents also an important route of dispersion, as it allows As to be transported globally [17,18].…”

This review describes the different steps involved in the determination of arsenic in air, considering the particulate matter (PM) and the gaseous phase. The review focuses on sampling, sample preparation and instrumental analytical techniques for both total arsenic determination and speciation analysis. The origin, concentration and legislation concerning arsenic in ambient air are also considered. The review intends to describe the procedures for sample collection of total suspended particles (TSP) or particles with a certain diameter expressed in microns (e.g. PM10 and PM2.5), or the collection of the gaseous phase containing gaseous arsenic species. Sample digestion of the collecting media for PM is
