Inorganic arsenic and iron(II) distributions in sediment porewaters investigated by a combined DGT - colourimetric DET technique


24 A new approach for investigating the biogeochemistry of inorganic arsenic and iron(II) in freshwater, 25 estuarine and marine sediments is reported. The recently developed Metsorb DGT technique for the 26 measurement of total inorganic arsenic and colourimetric DET technique for the measurement of 27 iron(II), were utilised in combination to determine co… (More)
