| Abstract | The contents of the major elements sodium, potassiuizi, calcium and magnesium, and the minor elements iron, manganese, zinc, copper, cobalt, lead, cadmium and mercury have been determined in relation to the reproductive cycle of ovaries in cod (Gadus ~norr/~zln). In addition were determined thc cobalt-containing vitaillin B ,,by nlicrobiological assay of some of the samples, All ovaries were collected from cod caught off the Western coast of Norway, and aI1 analyses were bascd on freeze-dried samples. Tlie results are reported on the basis of wet weight and duy matter, and the relations to the reproductive cycle are given graphically. The contents of calciun~, potassium, magnesium and zinc, showed different but significant decreases during the reproductivc cycle, whereas sodiuliz, manganese and copper showed significant increases. Calculation of cobalt derived from vitamin B,, compared with total cobalt showed a high degree of correlation, indicating that cobalt in the ovaries is present as part of vitamin B,,. The levels of lead, cadmium and izlercury were well below the limits given as provisional tolerable weekly intakes proposed by FAO/WHO. |
