Arsenic speciation in seaweeds using liquid chromatography hydride generation atomic fluorescence spectrometry (HPLC-HG-AFS)

摘要

The content of total and inorganic arsenic in three marine macroalgae species from a pristine location of the North Eastern Atlantic Ocean (Galway Bay, Ireland) was determined using Hydride Generation-Atomic Fluorescence Spectrometry (HG-AFS). Total arsenic concentrations ranged from 27.1 to 83.2 μg g~(-1) (dry weight). Mean inorganic arsenic concentrations ranged from 0.03-3.64 μg g~(-1) (dry weight). Laminaria digitata had the highest total and inorganic arsenic content. The data provides baseline concentrations for arsenic compounds in commercially important seaweeds.
