From: Mercury in the human adrenal medulla could contribute to increased plasma noradrenaline in aging
Mercury in the adrenal medulla in increasing ages. Mercury starts appearing in the adrenal medulla in the 21–40 years group, where it is present in 52% of people. The proportion of people with mercury in the medulla increases to 80% in the 41–60 years group, and reaches a maximum of 90% in the final 81–104 years group. Numbers of people in groups are above the bars.
