“…Developments can be followed in the regular annual review literature, 15 and have been recently reviewed. 80% of these publications report on the development or use of a method in which ICP-MS is used as the detector, from which it is clear that ICP-MS has one or two drawbacks as an elementspecific detector for HPLC: the instrument is not able to handle a wide range of mobile-phase compositions and some efforts have to be made to prevent the interference from chlorine, which produces an isobaric overlap, in quadrupole instruments, at m/z 75 due to the formation of 40 Ar 35 Cl + in the spectrometer. Detection by the more robust ICP-OES does not suffer from these problems, but the detection capability is inherently poorer than that of ICP-MS. For many analyses, this may not be the limiting factor, as the arsenic species are present in relatively high concentrations.…”

Several procedures, involving various solvents and ultrasound, were evaluated for the extraction of four arsenic species, arsenite (As(III)), arsenate (As(V)), monomethylarsonate (MMA) and dimethylarsinate (DMA), from a silt loam soil to which species had been added at a concentration of 20 mg kg À1 . The best extraction was by a two-stage procedure: shaking for 24 h in the presence of 0.1 mol l À1 phosphoric acid followed by shaking for 24 h in 1.0 mol l À1 sodium hydroxide solution. The arsenic species in the extracts were separated by high performance ion-exchange liquid chromatography, derivatized to hydrides by reaction with tetrahydroborate(III) in a multi-mode sample introduction system (MSIS) and quantified by ICP-OES. Detection limits in solution ranged from 0.4 (As(III) and DMA) to 1 (MMA and As(V)) mgl À1, corresponding to 10 and 25 mgkg À1 in a 0.2 g soil sample and 5 ml of extractant. The most significant change over time was that As(III) was converted to As(V). When each species was added individually, arsenic was 100% recovered over a period of several months. When all four species were added together, the recovery was 89%. As the precipitation of humic acids was slow, the sodium hydroxide extract could be acidified and analyzed without loss of analyte species.

Atomic Fluorescence Spectrometry (AFS) is an ideal detection technique for speciation studies concerning hydride forming elements (mainly As, Se and Sb) and Hg. The analytical features of AFS, such as detection limits below the mg L À1 and the wide linear calibration range, up to the mg L À1, allow its application to a great variety of environmental, biological and food samples. AFS represents a suitable alternative to other atomic spectrometers commonly employed in speciation studies such as Atomic Absorption Spectrometry (AAS) and Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). The instrumentation used for AFS and the design of the vapour generation and optical layouts required to sustain the full benefits of the AFS approach are also described. The present review explains and comments on the instrumental couplings of chromatographic (HPLC and GC) and nonchromatographic separations (CE) with AFS detection, with online hydride generation for the speciation of inorganic and organic compounds of As, Se and Sb, and cold vapour for Hg. Other optional intermediate steps are online photo-oxidation (UV), pyrolysis or Microwave Assisted Digestion (MAD) for non-directly reducible compounds. Many different sample types (e.g. water, soils, air, biota, food) have been analysed using these instrumental couplings with AFS detection. These are summarised and discussed.

The qualitative and quantitative analysis of the different arsenic species in Korean oyster samples was performed to provide the vital information of food safety of the marine sample in terms of the arsenic species. Korean marine samples, oysters, were obtained from nine sites in the western and southern areas of South Korea. Inductively coupled plasma mass spectrometry (ICP-MS) was used to measure the total arsenic. The different arsenic species in the oyster were separated by ion chromatography (IC), and then detected by ICP-MS. Extraction of arsenic species was performed with the mixed solvent of the methanol:water (3:1). The extraction efficiency of arsenic species (the ratio of total amount of the different arsenic species to the total arsenic in the oyster) for nine oysters was approximately 73-81%. The major arsenic species in the oyster was arsenobetaine, and its concentration in the samples was in the range of 7-16 mg/kg that was more than 90% of the total organic arsenic in the oyster. As(III) was not generally detected while the trace As(V) was detected in most oysters.Keywords: Arsenic speciation, Korean marine sample, Oyster, Ion chromatography, Inductively coupled plasma-mass spectrometry IntroductionArsenic has been known as a carcinogenic element that might be accumulated and biologically toxic in human body. [1][2][3][4][5] The element exists in various chemical forms, including trivalent and pentavalent states, inorganic and organic compounds, and about 30 different chemical species has been reported ( Table 1). In general, arsenic species are classified as inorganic arsenic and organic arsenic species. Inorganic arsenic species were formed with oxygen, sodium, chlorine, and sulfur. Organic arsenic species were formed with carbon, hydrogen, and oxygen existed in the animal and plant. 4 Even though the toxicological mechanism was not revealed, the inorganic arsenic species have been reported to be more toxic than organic arsenic species. 6,7 In particular, arsenite (As(III)) is more toxic than arsenate (As(V)). As a small amount of inorganic arsenic species have been known to be fatal to human being, it had been used as an assassination chemical and deadly drug in the middle ages. But arsenobetaine (AsB) and arsenocholine (AsC) of organic arsenic species have been known to be nontoxic species.

In addition, inorganic arsenic could not be formed in a metabolism of organic arsenic in a mammal due to the strong bond of arsenic and carbon. Methylarsonic acid (MMA) and dimethylarsinic acid (DMA) could be restrictively metabolized, and excreted in a urine without changes of the chemical forms. Accordingly...
