Aluminum and Mercury Synergy: A “Perfect Storm” • World Mercury Project
World Mercury Project note: When it comes to aluminum and mercury, one plus one does not equal two. The toxicity of mercury alone, and the toxicity of aluminum alone—both of which are concerning enough—are each far below the toxicity that results from exposure to both. Tests of the two metals in combination show that the toxicity levels skyrocket. How long have regulators known this fact?
Aluminum and mercury are two of the most prevalent heavy metals to which humans are exposed, whether via food and food additives, drinking water, occupational and environmental exposures or from medical-dental products such as vaccines and amalgam fillings. These exposures are a particular concern during critical neurodevelopmental stages, especially because both metals are neurotoxic “at doses well below the current reference levels considered to be safe.”
…the reasoning that has allowed such high levels of aluminum to remain in childhood vaccines is deeply flawed and places infants at risk of acute, repeated, and possibly chronic exposures of toxic levels of aluminum.
A variety of recent studies have focused on aluminum overload prenatally and perinatally. Nowhere is the overexposure to aluminum more apparent than in childhood vaccines. A two-month-old infant may receive up 1,225 micrograms of aluminum from the adjuvants in vaccines at a single well-baby appointment and a cumulative 4,925 micrograms by 18 months of age—astronomical levels that have never been assessed for safety. A 2018 analysis concluded that the reasoning that has allowed such high levels of aluminum to remain in childhood vaccines is deeply flawed and “place[s] infants at risk of acute, repeated, and possibly chronic exposures of toxic levels of aluminum.”
Given that neurotoxicity is already a major concern for aluminum and mercury when considered on their own, what happens when a developing fetus or infant incurs exposure to both together? Toxicologists have known for a long time that “co-exposure to multiple metals can result in increased neurotoxicity compared to single-metal exposure, in particular during early life.” Retired University of Kentucky chemistry professor Boyd Haley, a mercury expert, noted years ago that toxicity from exposure to multiple metals is not additive but synergistic and that “no one can state what is a ‘safe’ level of…exposure without knowing the concentration of all other factors that may synergistically exacerbate…toxicity.”
