Abstract
    We present an historical account of marine arsenic research and current views on the biotransformation of arsenic in marine ecosystems. Research on arsenic in marine sediments, sea water, marine algae, and marine animals is reviewed from 1900 to the present. Emphasis is placed on work examining the chemical form of arsenic in the various marine compartments. In marine ecosystems arsenic can occur in many different chemical forms, including arsenite and arsenate, methyl arsonic and dimethylarsinic acids, trimethylarsine oxide, tetramethylarsonium ion, arsenobetaine, and a number of arsenic-containing ribosides. The biotransformation of these marine arsenicals is discussed, in particular the biogenesis of arsenic-containing ribosides in marine algae and the origin of arsenobetaine in marine animals are considered.
