Additionally, the biotoxicity and bioavailability of As strongly depend on its chemical species, inside the identical way that types of arsenite and arsenate are known to become by far the most toxic types, that are categorized to a class 1, no threshold carcinogen, whilst organic species, as an example, methylarsonic acid (MMA), dimethylarsinic acid (DMA), and arsenobetaine (AsB), are significantly much less toxic to marine organisms and humans [19]. In this study for all seafood samples the inorganic arsenic concentration was below LOD. In contrast to inorganic forms, organic arsenic species were located in the seafood samples. The predominant form of the arsenic species was arsenobetaine within the range 2.2210.69 mg g-1 . The highest concentration was discovered in Argentine red shrimp, along with the lowest, in white shrimp. In the case of speciation evaluation of As in shellfish, equivalent to that in this study, the highest concentration was obtained of AsB forms. For shellfish, exactly where the clam samples dominate, the range of AsB was 7.8785.817 mg g-1 , which was analyzed in extract right after acid mineralization [19]. Within this study, inside the case of clams, AsB was determined at a similar concentration level, however it ought to be emphasized that the sample was extracted with water and not with acids. F.
