The Effect of Phosphate on the Bioaccumulation and Biotransformation of Arsenic(V) by the Marine Alga Fucus gardneri
Arsenic is present in the natural environment and living organisms in different chemical forms (Cullen and Reimer 1989). In the marine environment, high concentrations of arsenic occur in macroalgae with concentration factors of 1000 to 10,000 reported (Cullen and Reimer 1989; Francesconi and Edmonds 1993; Francesconi and Edmonds 1997), and algae seem to be able to accumulate arsenic more efficiently than the higher members of the food web. Few studies have been reported, however, on either the mechanism of arsenic accumulation, or on the algae pathways through which the arsenic is accumulated and biotransformed (Francesconi and Edmonds 1997).
