Occurrence and Speciation of Arsenic in Common Australian Coastal Polychaete Species

Abstract: Environmental Context. In well-oxygenated water and sediments, nearly all arsenic is present as arsenate (AsO43−). As arsenate is a phosphate (PO43−) analogue, organisms living in arsenate-rich environments must acquire the nutrient phosphorus yet avoid arsenic toxicity. Organisms take in and transform arsenic compounds by many means. Three major modes of arsenic biotransformation have been found to occur in the environment—redox transformation between arsenate and arsenite (AsO2−), the reduction and methylati… Show more

“…With the advent of modern analytical instrumentation, such as high pressure liquid chromatography coupled to an inductively coupled mass spectrometer or a mass spectrometer [4] and X-ray spectroscopy, arsenic is being analysed in more and diverse samples including marine organisms such as polychaetes [5] and scallops, [6] terrestrial organisms such as mushrooms and snails, [7,8] food crops [9] and animal and human urine. [10] These studies have led to the discovery of new arsenic compounds, e.g.…”
