    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mercury; methylmercury; aquatic systems; estuary; Hg; MeHg; bioaccumulation; methylation; demethylation; evasion; sediment; water; terrestrial sources; atmospheric sources; climate change; eutrophication;

    Abstract : Monomethylmercury, MeHg, is formed under anoxic conditions in waters, sediments and soils and then bioaccumulated and biomagnified in aquatic food webs, negatively effecting both human and wildlife health. It is generally accepted that precipitation of mercury, Hg, and adsorption of Hg to e.g. READ MORE

  6. 4. On diet in ankylosing spondylitis
