Abstract

A sample of liver from the marine mammal Dugong dugong was found to have an iron concentration of 137 000 Μg g-1 Fe dry weight. Histological examination of the tissue revealed dense extracellular deposits of iron-containing particles about 40 to 80 Μm in diameter. Mössbauer spectra of the sample at temperatures between 17 and 200 K show superparamagnetic behaviour with a mean superparamagnetic blocking temperature of about 67 K, with the sextet being extinguished between 160 and 200 K. The blocking temperature and spectral parameters are indicative of the goethite-like form of hemosiderin that has previously been reported in some iron-loaded thalassemic human tissues.
