“…In oyster samples (N07), the iAs concentration was up to 0.14 mg kg −1 , and in all samples of trout (N011), fish feed (N01) and fish meal (N01), concentrations below the LOD (0.08 mg kg −1 ) were found. The contents were in accordance with previously reported results for samples of marine origin, including fish (<0.002-0.006 mg kg −1 ) [7], shellfish (0.001-0.26 mg kg −1 ) [19] and fish feed (0.01-0.06 mg kg −1 ) [39]. The iAs levels detected in the oyster and fish samples were much lower than the MLs for fish (2 mg kg −1 ) and molluscs (1 mg kg −1 ) in Australia and New Zealand [13].…”

“…Inorganic arsenic consists of arsenite in oxidation stage three (As III ) and arsenate in oxidation stage five (As V ). The content of iAs in seafood is generally low, especially in fish where concentrations below detectable levels (<0.001 mg kg −1 ) are often reported [7,8]. In shellfish, somewhat higher levels are usually found, and in a few cases, very high levels (>0.5 mg kg −1 ) have been reported in bivalves [9,10].…”

“…The recent increased emphasis on dietary iAs exposure, partly encouraged by the recent EFSA [3] and WHO [11] evaluations, have initiated several studies on specific determination of iAs levels in foodstuffs [7,19,21], in all of which iAs is determined by HPLC-ICP-MS. However, many laboratories involved in feed and food control do not have the ICP-MS technique available, mainly due to the relatively high cost of investment for this technology compared with other elemental detection techniques like, e.g.…”

The present paper describes a novel method for the quantitative determination of inorganic arsenic (iAs) in food and feed of marine origin. The samples were subjected to microwave-assisted extraction using diluted hydrochloric acid and hydrogen peroxide, which solubilised the analytes and oxidised arsenite (As(III)) to arsenate (As(V)). Subsequently, a pH buffering of the sample extract at pH 6 enabled selective elution of As(V) from a strong anion exchange solid-phase extraction (SPE) cartridge. Hydride generation atomic absorption spectrometry (HG-AAS) was applied to quantify the concentration of iAs (sum of As(III) and As(V)) as the total arsenic (As) in the SPE eluate. The results of the in-house validation showed that mean recoveries of 101-104% were achieved for samples spiked with iAs at 0.5, 1.0 and 1.5 mg·kg(-1), respectively. The limit of detection was 0.08 mg kg(-1), and the repeatability (RSD(r)) and intra-laboratory reproducibility (RSD(IR)) were less than 8% and 13%, respectively, for samples containing 0.2 to 1.5 mg kg(-1) iAs. The trueness of the SPE HG-AAS method was verified by confirming results obtained by parallel analysis using high-performance liquid chromatography coupled to inductively coupled plasma mass spectrometry. It was demonstrated that the two sets of results were not significantly different (P < 0.05). The SPE HG-AAS method was applied to 20 marine food and feed samples, and concentrations of up to 0.14 mg kg(-1) of iAs were detected.

“…many different forms, no such limit has been set. However, although fish muscle may show high concentrations of total As, the portion of the most inorganic form, inorganic As, is generally low (Francesconi and Kuehnelt, 2002;Edmonds and Francesconi, 2003;Francesconi, 2010;Julshamn et al, 2012). The nontoxic organic arsenobetaine is assumed to be the dominating As species in fish, although oily fish may also contain considerable amounts of arsenolipids, for which the level of toxicity is less known (Sele et al, 2012).…”

“…The method is applied to rice, wheat, and tuna fish samples. Julshamn et al 201 apply an extraction method for iAs based on 0.07 mol L À1 HCl and 3% H 2 O 2 at 90 C for 20 min. The method is applied to determine iAs in 25 fish samples from Norwegian seas.…”

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

2016

View full text Add to dashboard Cite

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.
