Preliminary study suggests the following Mercury reaches a ceiling level in brains at about 12-18 months residues in man reach similar levels and also show no correlation with age. Mercury tends to accumulate in the liver with age, reaching fairly high levels. Cadmium accumulates in the kidney, as it does in man, where it is known to occur in higher concentrations than in other organs. There do not seem to regional differences in metal concentrations in teeth, but some metals were found in greater quantities in younger seals than in old ones, probably related to the pattern of tooth growth. There are regional differences in the amounts of mercury in the tissues, but there does not seem to be any relationship with possible agricultural or industrial pollution.
