"It is previously reported that mercury is stored in the pituitary
of dental personnel [49]. In the present study signif-
icant correlations between number of surfaces filled with
amalgam and mercury concentrations in pituitary and
thyroid. Probably, mercury is stored together with selenium
in these tissues, resulting in very long biological half
times [54]."

Very good article thank you for posting.

"A small fraction of MeHg in the brain demethylates to
inorganic mercury, which is retained for very long times,
especially in pituitary and thalamus [33], probably
mainly due to association with selenium to highly insoluble
mercury selenide"


I'm not sure what to make of this. There is a lot of mention of Selenium being bound to mercury making the mercury hang around for a LONG time. If this telling us that supplementing Selenium is a bad idea?

Selenium is an essential trace element, which is vital to the activation of GSH- containing, liver detoxification enzymes and also to the antioxidant enzyme, Glutathione peroxidase, important in neutralizing free peroxide radicals and oxidized lipids. Tolerance of selenium may be limited by its binding to, redistribution and precipitation of mercury in the tissues, which may induce nausea, digestive disturbances, vertigo, etc. For those who do not tolerate selenium, use of Vitamin E (Tocopherols and Tocotrienols) to counteract mercury-induced, tissue lipid peroxidation is indicated. Vitamin E works with selenium to neutralize mercury.

Notice how it mention "binding to, redistribution and precipitation of mercury" ab out Selenium. It looks like you should always supplement Vitamin E when taking selenium.
