Rethinking mercury: the role of selenium in the pathophysiology of mercury toxicity
Published: 2017
SYNOPSIS

Mercury in the body produces a selenium deficiency state that increases toxicity.

CITATION

Spiller HA. Rethinking mercury: the role of selenium in the pathophysiology of mercury toxicity. Clinical Toxicology. 2018;56(5):313-326.

SUMMARY

This study makes the case that mercury’s multifaceted interactions with selenium are a central feature of mercury toxicity. The authors argue that “the previously suggested ‘protective effect’ of selenium against mercury toxicity may in fact be backwards”—because of mercury’s affinity for selenium, mercury can actually produce a selenium deficiency state that promotes oxidative stress and inhibits the body’s regenerative mechanisms. Depending on the form of mercury and other factors, selenium supplementation may have some benefits for restoring adequate selenium status and mitigating the toxicity of mercury, but it does not appear to promote increased elimination of mercury.

Thimerosal induces toxic reaction in non-sensitized animals
Published: 1994
SYNOPSIS

Thimerosal used in vaccines increases risks of side effects.

CITATION

Uchida T, Naito S, Kato H, Hatano I, Harashima A, Terada Y, Ohkawa T, Chino F, Eto K. Thimerosal induces toxic reaction in non-sensitized animals. International Archives of Allergy and Immunology. 1994;104(3):296-301.

SUMMARY

A two-decades-old study in mice showed that thimerosal in vaccines may “augment” vaccine side effects in humans. Injection of a thimerosal-containing solution into mice resulted in hypersensitive reactions, including severe swelling and acute inflammation at the injection site with an hour of receiving the injection.
