Abstract: Eighteen cadavers from routine autopsy casework were subject to a study of tissue levels of total mercury in brain, thyroid, and kidney samples by atomic absorption. On these same cadavers, all dental amalgam fillings (the most important source of inorganic mercury exposure in the general population, according to the World Health Organization (WHO) were charted. Total mercury levels were significantly higher in subjects with a greater number of occlusal amalgam surfaces (>12) compared with those with fewer occlusal amalgams (0-3) in all types of tissue (all P <= 0.04). Mercury levels were significantly higher in brain tissues compared with thyroid and kidney tissues in subjects with more than 12 occlusal amalgam fillings (all P <= 0.01) but not in subjects with 3 or less occlusal amalgams (all P >= 0.07).

Latest Research Linking Mercury To Autism

Mercury toxicity: Genetic susceptibility and synergistic effects
Boyd E. Haley, PhD

Abstract
Mercury toxicity and intoxication (poisoning) are realities that every American needs to face. Both the Environmental Protection Agency and National Academy of Science state that between 8 to 10% of American women have mercury levels that would render any child they gave birth to neurological disorders. One of six children in the USA have a neurodevelopmental disorder according to the Centers for Disease Control and Prevention. Yet our dentistry and medicine continue to expose all patients to mercury. This article discusses the obvious sources of mercury exposures that can be easily prevented. It also points out that genetic susceptibility and exposures to other materials that synergistically enhance mercury and ethyl-mercury toxicity need to be evaluated, and that by their existence prevent the actual determination of a "safe level" of mercury exposure for all. The mercury sources we consider are from dentistry and from drugs, mainly vaccines, that, in today's world are not only unnecessary sources, but also sources that are being increasingly recognized as being significantly deleterious to the health of many.

From the Conlusion:

... If certain infants are more susceptible to mercury toxicity due to their inability to excrete mercury then it seems plausible that, since this is a genetic susceptibility, older individuals may suf fer from the inability to excrete mercury also. Based on the ability of mercury to mimic many of the biochemical aber rancies found in AD brain and to produce aspects of the pathological diagnostic hallmarks of AD it seems plausible that AD is a disease related to mercury toxicity. The published decrease of mercury in the nail tissue of AD versus normal age-matched individuals seems to support this possibility.
Finally, the synergistic effects of other heavy metals, diet, antibiotics, etc. on mercury toxicity make it impossible to define a "safe level of mercury exposure." Therefore it is imperative that we try to eliminate all exposure to mercury; and removal from dentistry and medicines is most important and critical for human health.

Critical Research Abstract

Iatrogenic Exposure to Mercury After Hepatitis B Vaccination in Preterm Infants.

Stajichi GV; Lopex, GP; Harry, SE; Sexson, WR.
J Pediatr., 136(5):679?8 1, May 2000.

ABSTRACT: Thimerosal, a derivative of mercury, is used as a preservative in hepatitis B vaccines. We measured total mercury levels before and after the administration of this vaccine in 15 preterm and 5 term infants. Comparison of pre- and post- vaccination mercury levels showed a significant increase in both preterm and term infants after vaccination.

Additionally, post-vaccination mercury levels were significantly higher in preterm infants as compared with term infants. Because mercury is known to be a potential neurotoxin to infants, further study of its pharmaco dynamics is warranted.
