“…4,7,8,11 The slightly lower concentration of AB found by extraction with water corresponds to the results of Londesborough et al 10 However, Mattusch and Wennrich reported an AB concentration of 16.5 mg As kg À1 dry mass obtained by extraction with water. 9 The presence of TMAO published by one working group as 0.4 mg As kg À1 dry mass 10 was not confirmed by our work, although this concentration is above the detection limit of our method. AC was also below the detection limit, which is in agreement with the published concentration of 0.02 mg As kg À1 dry mass, 4,10 although values of $0.09 mg As kg À1 dry mass were also reported.…”

The NRCC standard reference material DORM-2 and the marine brown alga Hijiki fuziforme were extracted with water, methanol/water (9 1), and 1.5 M orthophosphoric acid. The extracts from DORM-2 were analyzed by HPLC-ICP-MS for arsenobetaine, arsenocholine, trimethylarsine oxide, and the tetramethylarsonium cation and the extracts from H. fuziforme for arsenous acid, arsenic acid, dimethylarsinic acid, methylarsonic acid, and four arsenoriboses. Almost no differences between the three extractants were observed when DORM-2 was investigated. Only arsenobetaine was slightly better extracted with 1.5 M orthophosphoric acid or methanol/water (9 1) than with water. The sum of all extractable compounds (arsenobetaine, the tetramethylarsonium cation, and a formerly unknown compound recently identified as the trimethyl(2-carboxyethyl)arsonium ion) accounted for 94% of the total arsenic when 1.5 M orthophosphoric acid was used, for 92% when methanol/water (9 1) was used, and for 87% when water was used. Significant differences in the extraction yields obtained for the alga were observed for arsenic acid and one of the arsenoriboses ('glycerol-ribose'). Orthophosphoric acid removed twice as much of this ribose from the algal material than water and three times more than methanol/water (9 1). Arsenic acid was 1.2 times better extracted with orthophosphoric acid than with water and ten times better than with methanol/water (9 1). Almost no differences in the extraction yields were found for dimethylarsinic acid and the other three riboses. Orthophosphoric acid extracted 76%, water 65%, and methanol/water 33% of the total arsenic from H. fuziforme.

“…Arsenic species were analyzed using HPLC-ICP-MS. The chromatographic separation was performed with a mixed-mode column IonPac AS7/ AG7 using a nitric acid gradient (Mattusch and Wennrich, 1998). The chromatographic equipment used consisted of an HPLC Series 1100 quaternary pump, degasser, and thermostated autosampler (Agilent Technologies) and was coupled online to an ICP-MS PQExcell (Thermo Scientific, Waltham, MA, USA).…”

Silicon (Si) reduces arsenic (As) levels in rice shoot and grain. However, the underlying mechanisms remain unclear. In this study, we examined the effect of Si application to three rice paddy soils on the dynamics of Si, iron (Fe), phosphorus (P), and As in the soil solution, As accumulation in rice straw, flag leaf, husk, brown rice, and polished rice, and on As speciation in polished rice. Silicon application to soil increased the concentrations of Si, Fe, As, and P in the soil solution, while the redox potential was unaffected. Arsenic concentrations of straw, flag leaf, and husk were reduced by half by Si application, while As concentrations of brown and polished rice were decreased by 22%. The main As species in polished rice was arsenite, As(III), with a fraction of 70%, followed by dimethylarsinic acid (DMA) and arsenate, As(V), with 24% and 6%, respectively. Silicon application to the soil did not affect DMA or As(V) concentration of polished rice, while the As(III) concentration was reduced by 33%. These results confirm that Si reduces As(III) uptake and translocation into the shoot. Furthermore, data indicate that decrease of As concentration of polished rice is due to decreased As(III) transport into grain. Possible underlying mechanisms are discussed.

“…As III , MMA, DMA, As V , AB, TMAO, AC and TeMAs + . 27,28 The separation of neutral, anionic and cationic species was successfully accomplished by the addition of an ion-pairing agent (benzene disulfonic acid) in the nitric acid mobile phase. Kohlmeyer et al 29 have demonstrated a similar approach for the separation of 17 arsenic species from various seafood products.…”

Arsenic speciation analysis in marine samples was performed using ion chromatography (IC) with inductively coupled plasma mass spectrometry (ICP-MS) detection. The separation of eight arsenic species, viz. arsenite, monomethyl arsonic acid, dimethylarsinic acid, arsenate, arsenobetaine, tetramethylarsine oxide, arsenocholine and tetramethylarsonium ion was achieved on a Dionex AS4A (weaker anion exchange column) by using a nitric acid pH gradient eluent (pH 3.3 to 1.3). The entire separation was accomplished in 12 min. The detection limits for the eight arsenic species by IC-ICP-MS were in the range 0.03-1.6 µg l −1 , based on 3σ of the blank response (n = 6). The repeatability and day-to-day reproducibility were calculated to be less than 10% (residual standard deviation) for all eight species. The method was validated by analyzing a certified reference material (DORM-2, dogfish muscle) and then successfully applied to several marine samples, e.g. oyster, fish muscle, shrimp and marine algae. The low power microwave digestion was employed for the extraction of arsenic from seafood products.
