It was confirmed that Mössbauer spectroscopy is an useful tool for measurement of
biological tissues even if the concentration of iron in the samples is very low. Mössbauer
spectra revealed a presence of particles with non-magnetic behaviour at room temperature. At
temperature 4.2 K almost all particles exhibit magnetic behaviour. The rest of the particles
still exhibits superparamagnetic behaviour what indicates that their blocking temperature is
lower than 4.2 K. It was suggested that those might be very small haemosiderin particles.
Parameters the sextet-like components suggest possible presence of goethite, akaganéit or
ferrihydrite.
