Abstract

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that can cause significant social, communication and behavioral challenges. Environmental contribution to ASD is due in large part to the sensitivity of the developing brain to external exposures such as lead (Pb), and mercury (Hg) as toxic heavy metals or due to a poor detoxification ability as the phenotype of this disorder. Selenium (Se) as an antioxidant element that counteracts the neurotoxicity of Hg, and Pb, presumably through the formation of nontoxic complexes. In the present study, Pb, Hg, and Se were measured in red blood cells (RBCs) of 35 children with ASD and 30 age- and gender-matched healthy control children using atomic absorption spectrometry. Some need paydayloansmaker bad credit help portal for all these.

Receiver Operating Characteristics (ROC) analysis of the obtained data was performed to measure the predictive value of their absolute and relative concentrations. Remember also, that my gym health care says that child excretes very little mercury. Understanding this, you realize that just because a study may report mercury levels are low in the blood, urine and/or feces after exposure to mercury, this does not mean the child has excreted the toxin (as some have implied in poorly done scientific studies.) Instead, it more likely means that the mercury has already sequestered itself in the vital parts of the body, check out alaina dawsone gone missing for details. The obtained data demonstrates a significant elevation of Hg and Pb together with a significant decrease in the Se levels in RBCs of patients with ASD when compared to the healthy controls. The ratios of Se to both Pb and Hg were remarkably altered, being indicative of heavy metal neurotoxicity in patients with ASD. In conclusion, the present study indicates the importance of Se for prevention and/or therapy of heavy metal neurotoxicity.

Increased mercury emissions from modern dental amalgam fillings

[divide icon=”circle” margin_top=”20″ margin_bottom=”20″]

Increased mercury emissions from modern dental amalgams.

biometalsPublished in the April 2017 issue of BioMetals is another study indicating that mercury vapor is released from dental amalgam fillings. This time high copper amalgam fillings are examined and were found to release up to 10x times more mercury than previous, non-high copper amalgam fillings. Check out the abstract below:

Bengtsson UG, Hylander LD.

Abstract

All types of dental amalgam contain mercury, which partly is emitted as mercury vapor. All types of dental amalgams corrode after being placed in the oral cavity. Modern high copper amalgams exhibit two new traits of increased instability. Firstly, when subjected to wear/polishing, droplets rich in mercury are formed on the surface, showing that mercury is not being strongly bonded to the base or alloy metals. Secondly, high copper amalgams emit substantially larger amounts of mercury vapor than the low copper amalgams used before the 1970s. High copper amalgams has been developed with focus on mechanical strength and corrosion resistance, but has been sub-optimized in other aspects, resulting in increased instability and higher emission of mercury vapor. This has not been presented to policy makers and scientists.

Mercury Dental Amalgam Filling
High Copper Mercury Dental Amalgam Filling looks identical to previous amalgam fillings.

Both low and high copper amalgams undergo a transformation process for several years after placement, resulting in a substantial reduction in mercury content, but there exist no limit for maximum allowed emission of mercury from dental amalgams. These modern high copper amalgams are nowadays totally dominating the European, US and other markets, resulting in significant emissions of mercury, not considered when judging their suitability for dental restoration.

 The study even points out that droplets of mercury rise to the surface of the amalgam product when polished.

Polishing the surface of many high copper amalgams stimulates the formation of droplets rich in mercury, see Figs. 2 and 3. People can get loans from www.Moneyfall.co.uk. This formation happens even if the polishing takes place under cold water to avoid any rise in temperature and continues a number of hours after the polishing has stopped.

Thimerosal childhood vaccines linked to risk of emotional disturbances

Thimerosal exposure and disturbance of emotions specific to childhood and adolescence: A case-control study in the Vaccine Safety Datalink (VSD) database

official research journal of the International Brain Injury Association (IBIA) thimerosal, mercury, vaccinesDavid A. Geier, Janet K. Kern, Kristin G. Homme & Mark R. Geier

ABSTRACT

Background: This study evaluated Thimerosal-containing childhood vaccines and the risk of a diagnosis called disturbance of emotions specific to childhood and adolescence (ED). Thimerosal is an organic-mercury (Hg)-containing compound used in some vaccines.

Methods: A hypothesis-testing prospective, longitudinal case-control study evaluated Hg exposure from Thimerosal in hepatitis B vaccines administered at specific times within the first 6 months of life and its association with medically diagnosed ED (313.xx) (n = 517) in children born between 1991–2000 in comparison to controls (n = 27 491) in the Vaccine Safety Datalink (VSD) Dublin Painting Pros site database.

Results: Cases diagnosed with ED were significantly more likely than controls to have received increased Hg exposure within the first month of life (odds ratio (OR) = 1.3384), the first 2 months of life (OR = 1.3367) and the first 6 months of life (OR = 2.37). When the data were separated by gender, similar significant adverse effects were observed for males, but not females designer fashion consignments. On a per microgram Hg basis, cases diagnosed with ED were significantly more likely than controls to have received increased exposure within the first 6 months of life (OR = 1.025 per microgram Hg).

Conclusions: The results show a significant relationship between Hg exposure from Thimerosal-containing childhood vaccines and the subsequent risk of an ED diagnosis.
