| Abstract: | Dulse from three geographically different areas and a common holding tank was analyzed for As, Cu, Cd, Pb, Se, Zn and Hg by flameless atomic absorption spectroscopy. Concentration ranges (μg/g dry weight) were: As 5.50-7.50, Cu 3.90-6.34, Cd 0.97-2.65, Pb 0.688-3.5, Se 2.00–2.91, Zn 57.5–84.1, Hg < 0.02. Percent moisture was 13.50-23.45. |
