From: Mercury in the human adrenal medulla could contribute to increased plasma noradrenaline in aging
LA-ICP-MS II. The dotted lines outline the adrenal gland in the section, the medulla is outlined by the internal dashed lines, and the cortex occupies the space between the dashed and dotted lines. Phosphorus LA-ICP-MS indicates the degree of cellularity. Mercury is present selectively in the medulla of one high-AMG sample (A). In the three low-AMG samples, mercury is present in the medulla in two (B,C), but not detected in one (D). Metals present in both cortex and medulla are lead (B–D), nickel (B,D), cadmium (C,D), mercury (D), iron (A), and bismuth (D). Cadmium is present selectively in one medulla (B). Metals mostly in the cortex are iron (B–D), aluminium (in the zona reticularis, A,D), cadmium (A) and silver (D). Scale = counts per second (proportional to abundance).
