Abstract:
Arsenic content of total and different species in ten types of algae were examined by using anion and cation exchange high performance chromatography (HPLC) and the inductively coupled plasma-mass spectrometry (ICP-MS). The total arsenic concentration in the algae was 1.7~38.7 mg/kg. In extractive, arsenosugars were dominant species. Arsenosugar PO4 was the major compound in most red algae samples (0.4~12.7 mg/kg), followed by arsenosugar OH (1.7~7.8 mg/kg), arsenosugar SO3, and DMA were however also found in all brown algae samples. Inorganic arsenic was not detected in all samples.
