Abstract A non‐destructive photon activation analysis technique with 30‐MeV bremsstrahlung followed by high‐resolution γ‐spectrometry is applied to multielement analysis of two brown algae, Laminaria religiosa and Sargassum horneri , and one red alga, Heterosiphoia japonica . This method is quite simple and gives good, reproducible results. Elemental abundances of nine elements including arsenic were determined. Arsenic content in the above algae are 50.8, 92.1, and 8.3 mg kg −1 (dry weight base), respectively. Arsenic contents in algae indifferent seasons and different locations do not show a large scatter. The concentration ranges of arsenic together with other essential main components (e.g. sodium, magnesium, phosphorus and chlorine) in a number of samples are summarized. The mean concentrations for these five elements are compared with the elemental abundance of these elements in seawater, and the high enrichment of arsenic and phosphorus is clearly observed.
