Thank you
@Amw66, for finding this info!
From the article - link noted just above:
"Then came a preliminary but really weird finding – elevated levels of mercury (not so weird) and high levels of uranium (really weird) associated with low selenium levels in the hair analyses of a significant subset of patients. Both the mercury and uranium issues derive from low selenium levels. Selenium, interestingly, also plays a role in the conversion of T4 to T3 in the thyroid. (Chris Kressler recommends getting your selenium levels tested and, in general, using
dietary methods (not selenium supplementation) to safely
increase selenium levels in hypothyroidism.)"
Several years ago, I tried to supplement with selenium as per medical advice. My symptoms really flared. I didn't get an explanation for this when I asked.
Mercury - one of my "favourite" topics. Especially that from dental amalgams. Until almost a decade into being ill with ME, I thought they were "silver" as described by dental personnel. No. They are 50% mercury, about 30% silver, and the rest are things like copper, zinc and tin. These fillings have been used for over a century, which somehow seems to mean they are safe?
Break an old fashioned mercury thermometer and you need an environmental spill kit to clean it up. Mercury warnings are posted about eating fish in lakes, but dentists can install mercury in your mouth. And odd world we live in.
From the FDA on mercury dental fillings:

From the link just above:
"Dental amalgam is a mixture of metals, consisting of liquid (elemental) mercury and a powdered alloy composed of silver, tin, and copper. Approximately 50% of dental amalgam is elemental mercury by weight. The chemical properties of elemental mercury allow it to react with and bind together the silver/copper/tin alloy particles to form an amalgam."
