Notes:
Arsenic speciation in a brown alga, Fucus gardneri, collected in Vancouver, B.C., Canada, was carried out by using high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). Hydride generation-atomic absorption spectrometry (HG-AAS) was used for total arsenic determination. The relative amounts of some arsenosugars 1 in growing tips are found to be different in comparison with the remainder of the plant. Fucus samples collected in summer contain 9 ppm of total arsenic. Most of the arsenic species are extractable. Fucus samples collected in winter contain relatively higher amounts of arsenic, 16-22 ppm, but only low amounts of this are extractable. © 1998 John Wiley & Sons, Ltd.
