Iodine and bromine in fish consumed by indigenous peoples of the Russian Arctic.

摘要: Fish muscle may constitute one of the main sources iodine (I) for indigenous peoples Russian Arctic, although limited information is available about its content in commonly consumed fish species. In current study, bromine (Br), I, essential elements (copper, selenium and zinc) other non-essential — specifically mercury, arsenic (As), cadmium, lead nickel have been quantified 10 species by people living Nenets Chukotka Regions. was analysed ICP-MS after nitric acid or tetramethylammonium hydroxide digestion. Certified reference materials were employed concentrations are reported as geometric means (GMs). Atlantic cod (6.32 mg/kg) navaga (0.934 mg/kg) contained substantially higher amounts I than all species, while broad whitefish had lowest (0.033 mg/kg). By comparison, more Br (14.5 mg/kg) ranging 7.45 mg/kg to 2.39 mg/kg northern pike. A significant inter-fish association between As freshwater marine observed, suggesting common perhaps parallel absorption patterns. Only and, lesser extent, constituted dietary I.
