Abstract

The following trace elements have been analysed in various algae samples: arsenic, copper, molybdenum, manganese, zinc, cobalt, antimony, selenium and iron. The ash content has also been determined. The samples were collected from two different localities in Norway, one (Trondheimsfjord) characterised by a relatively strong influence of river water, industrial waste etc.; the other (Reine in Lofoten) is free from this type of contamination. In the case of two species, Ascophyllum nodosum and Laminaria hyperborea, the variation in the content of trace elements has been studied during a one‐year period, samples being taken every second month. Considerable differences in the content of trace elements was found between the Laminariaceae and Fucaceae.
