“…Low EE (0.49-0.78) indicates that a fraction of As is not extracted. Similar results have previously been observed in Atlantic salmon, tuna, herring, pelagic and oily shes (Lischka et al 2013, Hackethal et al 2021, Nawrocka et al 2022, suggesting that the non-extractable compounds in our study are arsenolipids.…”

Levels of 14 trace elements (Al, Ti, V, Cr, Mn, Co, Ni, Zn, As, Se, Cd, Sn, Hg and Pb) and 5 arsenic species (arsenite/As(III), arsenate/As(V), monomethylarsonic acid/MA, dimethylarsinic acid/DMA and arsenobetaine/AsB) were assessed in the gonads of sea urchin samples (Paracentrotus lividus) from North-West Mediterranean Sea (French coast). The samples were collected from 13 sites characterized by different types and levels of chemical contamination. Trace elements levels were measured by inductively coupled plasma-mass spectrometry (ICP-MS) following microwave (acid) digestion in a closed system, whereas As speciation analysis was carried out by ion-exchange liquid chromatography coupled with ICP-MS after microwave assisted extraction. High levels of trace elements were found in sea urchins sampled from Corsica whereas the samples from Théoule were found to be the least contaminated. From all the analyzed urchin samples, none showed Cd, Hg or Pb concentrations above the regulatory levels set by the European Community (EC) No. 1881/2006 for seafood or bivalve mollusks. Regardin arsenic specation, AsB was confirmed to be the predominant species. Inorganic As (As(III) + As(V)) was mainly constituted by As(III), which was quantified in all samples. Methylated As forms (MA and DMA) represent 9 to 23% of the total As.

“…As arsenic metabolites in mushrooms include multiple compounds of similar properties, each separation approach has some limitations and cannot satisfy the full range analysis of arsenic species. Therefore, we adopted two HPLC separation columns—an ion exchange column and a hydrophobic column, which allowed us to achieve desirable analysis results [ 20 , 23 ]. The reduced forms of methylated arsenicals were not detected.…”

“…Arsenic speciation was assayed by HPLC-ICP-MS according to previously reported procedures with slight modifications [ 15 , 23 , 24 ]. The HPLC system for arsenic speciation consisted of a degasser, an HPLC column oven, an HPLC binary pump and a standard autosampler (NexSar HPLC, Perkin Elmer).…”

Mushrooms have unique properties in arsenic metabolism. In many commercial and wild-grown mushrooms, arsenobetaine (AsB), a non-toxic arsenical, was found as the dominant arsenic species. The AsB biosynthesis remains unknown, so we designed experiments to study conditions for AsB formation in the white button mushroom, Agaricus bisporus. The mushrooms were treated with various arsenic species including arsenite (As(III)), arsenate (As(V)), methylarsenate (MAs(V)), dimethylarsenate (DMAs(V)) and trimethylarsine oxide (TMAsO), and their accumulation and metabolism were determined using inductively coupled mass spectrometer (ICP-MS) and high-pressure liquid chromatography coupled with ICP-MS (HPLC-ICP-MS), respectively. Our results showed that mycelia have a higher accumulation for inorganic arsenicals while fruiting bodies showed higher accumulation for methylated arsenic species. Two major arsenic metabolites were produced in fruiting bodies: DMAs(V) and AsB. Among tested arsenicals, only MAs(V) was methylated to DMAs(V). Surprisingly, AsB was only detected as the major arsenic product when TMAsO was supplied. Additionally, AsB was only detected in the fruiting body, but not mycelium, suggesting that methylated products were transported to the fruiting body for arsenobetaine formation. Overall, our results support that methylation and AsB formation are two connected pathways where trimethylated arsenic is the optimal precursor for AsB formation.

“…As a comparative method to verify the accuracy of the developed nanosystem, HPLC-ICP/MS was used. As mentioned above, the samples were also prepared following the GB5009.11-2014, while the procedures for HPLC-ICP/MS computer-based determination of As( v ) were based on previously described methods, 20 which used a chromatography system consisting of ICP-MS (7700x, Agilent Technologies, USA) coupled with HPLC (1260, Agilent Technologies, USA) with the following anion exchange columns: an anion exchange guard column (Agilent Technologies part number G3154-65002, PEEK, 4.6 mm × 10 mm polymethacrylate), followed by an As speciation column (Agilent part number G3288-80000, PEEK, 4.6 mm id × 250 mm polymethacrylate) and PRP-X 100 (4.6 × 250 mm, 10 µm, PEEK) (Hamilton, Switzerland) with a PRP-X 100 anion exchange guard column (3 × 8 mm, 10 µm, PEEK) (Hamilton, Switzerland). The mobile phase of 50 mmol NH 4 (CO 3 ) 2 was prepared in a pH 8.5 aqueous solution of 1% (v/v) MetOH and 0.2 mM EDTA, and an equal degree elution method with a flow rate of 0.8 mL min −1 was used in the experiment.…”
