“…In general, the toxicity order of As compounds in several human cell lines may be as follows: (Hirano et al 2004;Petrick et al 2000). Moreover, arsenobetaine (AB), arsenocholine (AC), trimethylarsine oxide (TMAO), arsenosugars, arsenolipids and other organic As compounds are normally far less toxic than inorganic arsenic species (Choi et al 2011;Hsieh and Jiang 2012;Moreda-Piñeiro et al 2010. However, one exception to this was a recent study by Meyer et al (2014) who demonstrated that some arsenolipids were toxic.…”

Arsenic is a toxic metalloid and its pollution has become a global environmental problem. This paper reviewed the current knowledge on the speciation, toxicity and metabolism of arsenic in microalgae. A number of arsenic species are present in various microalgae. Due to the great toxicity of inorganic arsenic, microalgae may undergo different processes to reduce the arsenic toxicity, including cell surface binding, arsenite [As(III)] oxidation, arsenate [As(V)] reduction, methylation, transformation into arsenosugars or arsenolipids, chelation of As(III) with glutathione and phytochelatins, as well as excretion from cells. Several genes and enzymes involved in arsenic transformations have been identified and characterized. Many factors, especially nutrient elements (e.g., nitrogen and phosphorus) in cells and in culture, affect arsenic metabolic pathways of microalgae. Arsenic metabolism in the unicellular algae has gained considerable interest because these processes control not only the effectiveness of arsenic phycoremediation, but also the risk of arsenic contamination in algal products. Future research need to focus on (1) the regulative mechanisms of arsenic absorption, biotransformation and excretion at molecular level; (2) the effects of intracellular nutrient dynamics on arsenic speciation; (3) the impacts of culture regime on the arsenic metabolism in microalgae; (4) the transfer of arsenic species across aquatic food web in order to better evaluate the roles of microalgae in arsenic cycling.

“…These compounds generally occur as minor As species in seafood, with DMA being the most prominent. Molluscs can contain DMA at higher proportions (3–46%) than are typically seen in finfish or algae (Fricke et al 2004, Cleland et al 2009, Moreda-Piñeiro et al 2010, Whaley-Martin et al 2012, Berges-Tiznado et al 2013). Monomethyl As (MA) is uncommon in marine environments and is generally present in trace amounts only.…”

“…AB is also found in zooplankton (Shibata et al 1996, Takeuchi et al 2005) and some algae at the base of the foodweb, but its presence in algae might possibly be due to epiphytic plankton or bacteria on the surface of marine flora (Thomson et al 2007). In bivalve molluscs, which have complex As speciation, AB can be a significant portion of water soluble As (Francesconi and Edmonds 1997, Moreda-Piñeiro et al 2010, Berges-Tiznado et al 2013), whereas in cephalopods (Suner et al 2002) and crustaceans, which have much simpler As speciation, AB is the dominant species (Francesconi and Edmonds 1997, Hunter et al 1998, Francesconi et al 1999, Li et al 2003). In finfish As is also predominantly AB, although AsLipids can be a significant fraction in some oily fish (Taleshi et al 2010, Lischka et al 2013).…”

Seafood, including finfish, shellfish, and seaweed, is the largest contributor to arsenic (As) exposure in many human populations. In contrast to the predominance of inorganic As in water and many terrestrial foods, As in marine-derived foods is present primarily in the form of organic compounds. To date, human exposure and toxicological assessments have focused on inorganic As, while organic As has generally been considered to be non-toxic. However, the high concentrations of organic As in seafood, as well as the often complex As speciation, can lead to complications in assessing As exposure from diet. In this report, we evaluate the presence and distribution of organic As species in seafood, and combined with consumption data, address the current capabilities and needs for determining human exposure to these compounds. The analytical approaches and shortcomings for assessing these compounds are reviewed, with a focus on the best practices for characterization and quantitation. Metabolic pathways and toxicology of two important classes of organic arsenicals, arsenolipids and arsenosugars, are examined, as well as individual variability in absorption of these compounds. Although determining health outcomes or assessing a need for regulatory policies for organic As exposure is premature, the extensive consumption of seafood globally, along with the preliminary toxicological profiles of these compounds and their confounding effect on assessing exposure to inorganic As, suggests further investigations and process-level studies on organic As are needed to fill the current gaps in knowledge.

“…The extractant capability of different reagents was evaluated in the CRM DORM‐2 certified sample using a microwave‐assisted method and an ultrasound‐assisted method. In the CRM DORM‐2 only total As and arsenobetaine are certified but concentrations for other species are documented in the literature (Cava‐Montesinos et al ., ; Moreda‐Piñeiro et al ., , ). The sum of As(III), As(V), MMA and DMA (1.06 μg g −1 ) was employed as a target value for toxic As.…”

A nonchromatographic analytical procedure has been developed for the determination of arsenic in meat samples including the major toxic arsenic species arsenite, arsenate, monomethylarsonic acid (MMA) and dimetylarsinic acid (DMA). The method is based on the extraction of arsenic species in mild conditions, selective trivalent hydride formation and final determination by hydride generation atomic fluorescence spectroscopy (HG-AFS). Different extractant agents and two different procedures, microwave-assisted extraction (MAE) and ultrasound assisted extraction at room temperature, were evaluated for As species extraction. The method provided a limit of detection of 0.013 ng mL À1 and a mean relative standard deviation in actual samples of 0.3%. Data found for toxic As in meat samples varied from 0.42 ng g À1 in chicken muscle to 68 ng g À1 in pork liver. Percentage of toxic As respect to total As varied in the 9-46% range depending on the meat product.Determination of toxic arsenic in meat M.
