title: Transformations of arsenic in the marine environment.
abstract: It is ten years since arsenobetaine was first isolated from the western rock lobster Palinurus cygnus. Subsequently this naturally-occurring arsenical has been found in many species of marine animals contributing to the human diet. The identification of arsenic-containing ribofuranosides in algae and the production of dimethylarsinoylethanol from their anaerobic decomposition has allowed speculation on arsenic metabolism in marine organisms and has suggested a possible route to arsenobetaine from oceanic arsenate.
