	abstract = {we studied the arsenic speciation in human urine samples by using high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). We investigated the arsenic speciation in the urine collected from nine volunteers during a 3-day period after a meal of blue mussels, Mytilus edulis. We also studied the effect of cooking on the arsenic speciation. Arsenobetaine and dimethylarsinic acid (DMAA) were the major arsenic metabolites found in the urine samples. Significant amounts of unknown metabolites were also detected. The excretion patterns of arsenic from individuals were generally similar except for two subjects. One of whom excreted high amounts of arsenobetaine even though no arsenic-rich food was eaten for 3 days before the experiment. The results reveal that we need a better understanding of the metabolism of arsenic compounds by human. (C) 2004 Elsevier Inc. All rights reserved.},

	abstract = {The arsenic species present in the foot muscle of whelks, Buccinum undatum, collected from Newfoundland, Canada, were characterized by using high-performance liquid chromatography-inductively coupled plasma mass spectrometry. All samples contain high amounts of arsenic, mostly over 100 mug g(-1) (as arsenic, dry weight basis), and one sample contained up to 1360 mug g(-1). These values are considerably higher than those reported in other gastropods. Speciation studies of representative samples revealed arsenobetaine as the major water-soluble arsenic compound, together with trace amounts of an arsenosugar. No inorganic arsenic species were detected in the sample extracts, indicating that consumption of the whelks poses little human risk. Copyright (C) 2002 John Wiley Sons, Ltd.},

Male pre-spawning gonads contain 0.35-2.4 mug g(-1) of the dimethylarsinoylriboside, Female pre-spawning gonads contain 0.47-9.64 mug g(-1) of the same compound. Postspawning gonads, both male and female, contain higher concentrations of this compound (3.7-11.4 mug g(-1)). The total concentrations of water-soluble arsenic compounds are different in male and female pre-spawning gonads. These differences are not obvious in post-spawning gonads. Post-spawning gonads contain higher total concentrations of water-soluble arsenic compounds than pre-spawning gonads. Copyright (C) 2001 John Wiley \& Sons, Ltd.},

	abstract = {The brown alga, Fucus gardneri, was collected from Vancouver Island, B,C,, Canada. Fucus samples were acclimated in seawater and then exposed to arsenic(V) in artificial seawater, all under axenic conditions. The arsenic species in the Fucus samples were extracted into 1:1 methanol-H2O and identified by using ion-pairing high-performance liquid chromatography coupled to inductively coupled plasma mass spectrometry (HPLC-ICP-MS), Anion-exchange HPLC-ICP-MS was used to identify the arsenic species in the growth medium. It was found that similar to 73\% of the original arsenosugars in the F, gardneri samples were lost during the acclimation period. Arsenite [As(III)] and dimethylarsenate [DMA] concentration increased in the Fucus samples after exposure to arsenate [As(V)], A small increase in the concentration of an arsenosugar was seen during this period, accompanied by a further decrease in the concentration of two other arsenosugars. The experiments provided very little evidence for the hypothesis that arsenosugars are produced by the macroalgae. Copyright (C) 2001 John Wiley \& Sons, Ltd.},

	abstract = {The arsenic species present in a range of commercially available dried-algal food products were characterized by HPLC-ICP-MS, The products of marine origin contain up to four dimethylarsinylribosides (1) in the 8-49 ppm range and some also contain dimethylarsinic acid (DMAA). These species are easily extracted and account for most of the arsenic burden. One sample of a freshwater alga Nostoc sp, was found to contain a lower concentration of arsenic, 3 ppm, and only 34\% of this was extractable, The extract representing 1 ppm of arsenic contained one of the arsenosugars 1 found in the marine samples (93\%), the rest being DMAA, This is the first report of the identification of an arsenosugar from an organism of terrestrial origin, The implications of this result in connection with the global arsenic cycle are discussed.
