Abstract The following elements have been found in the lipid phase of samples of halibut ( Hippoglossus hippoglossus ) and tunny ( Thunnus thynnus ): arsenic, bromine, selenium, zinc, iron, phosphorus and sulphur, and in the non‐lipid phase: cadmium, lead, copper, selenium, zinc, iron, arsenic, mercury and sulphur. Of the results the following should be emphasised: a surprisingly high content of sulphur was observed in the lipid phase suggesting a new group of lipids. The results indicate, furthermore, a rather constant selenium to sulphur ratio in defatted meal while the corresponding ratio in the lipid phase is more variable. No accumulation of cadmium compared with zinc seems to take place.
