In Australia there are increasing reports of unruly children and teenagers running amok, bullying classmates, attacking police, teachers, parents, etc, etc. No doubt this is because of a variety of reasons but I have wondered what possible role their increasing addiction to wireless technology, i.e., mobile phones. wi fi, etc. might have in their anti-social behaviour – and whether chemical exposures could also be a factor. For example, in the 1990’s the Swedish Union of Clerical and Technical Employees in Industry (SiF) had produced a number of publications on both chemical and EMF hazards in the modern workplace ( See: https://www.emfacts.com/download/no_risk_Feb_7.pdf ). This was examined in far more detail in Gunni Nordstrom’s excellent book, The Invisible Disease, that chronicles the issue of chemical/EMR hazards in the workplace. (See: http://www.amazon.com/The-Invisible-Disease-Environmental-Electromagnetic/dp/1903816718 ). Evidence indicates that chemical exposure may increase susceptibility to EMR exposure. Perhaps EMR exposure also increases susceptibility to chemicals?
Research by the Karolinska Institute found that since 1972, when levels of Brominated Flame Retardants (related to PCBs) were virtually undetectable in human breast milk, dramatic annual increases have been measured. Much of this was apparently due to contaminated and recirculated air from outgassing electrical equipment in modern office buildings and from contamination in food. ( SiF, No Risk in the IT environment )
According to the Chapel Hill Consensus statement “the published scientific literature on human and animal exposure to low doses of BPA … reveals that human exposure to BPA is within the range that is predicted to be biologically active in over 95% of people sampled.” www.environmentalhealthnews.org/…/2007-0801bpaconsensus.pdf
So, we all are carrying around a potentially toxic load of chemicals in our bodies but it is not known what the effect of these chemicals will be for our health and longevity – or the legacy for our children.
Of importance here is the evidence that EMR exposure can cause leakage through the blood-brain barrier (BBB) – therefore allowing chemicals already circulating in the bloodstream to enter the brain and do cause damage on a neurological level.
Now consider the implications of the rat study findings by researchers at Washington State University on chemical exposures of rats and the effects on their descendants (below). It would be interesting to re-run the experiment but this time also expose a number of rats to both vinÂcloÂzolin and EMR to see what additional effect that might have on their offspring.

SciÂenÂtists have found inÂcreased stress senÂsiÂtiÂvity and difÂferÂences in weight gain in rats whose anÂcesÂtors were exÂposed to a horÂmone-disÂruptÂing chemÂiÂcal three generaÂtÂions earÂliÂer.
The reÂsearchÂers exÂposed pregÂnant rats to vinÂcloÂzolin, a popÂuÂlar fruit and vegÂeÂtaÂble funÂgiÂcide known to disÂrupt horÂmones. They then put the roÂdents”™ great-grandpups through varÂiÂous tests and found them more anxÂious, stress-senÂsiÂtive and prone to greatÂer acÂtiÂvity in stress-related brain arÂeas than unÂexÂposed rats”™ deÂscenÂdants.
“We are now in the third huÂman generaÂtÂion since the start of the chemÂiÂcal revÂoÂluÂtion, since huÂmans have been exÂposed to these kinds of toxÂins,” said DaÂvid Crews of the UniÂversÂity of TexÂas at AusÂtin, one of the inÂvesÂtiÂgaÂtors. “This is the anÂiÂmal modÂel of that.”
The difÂferÂences in weight gain seen in the study were inÂtriÂguing but reÂquire furÂther stuÂdy, he added.
It seems clear that “the anÂcesÂtral exÂpoÂsure of your great grandÂmothÂer alÂters your brain deÂvelÂopÂment to then reÂspond to stress difÂferÂentÂly,” said MiÂchael SkinÂner of WashÂingÂton State UniÂversÂity, who worked with Crews. The findÂings are pubÂlished in the latÂest isÂsue of the jourÂnal ProÂceedÂings of the NaÂtÂional AcadÂeÂmy of SciÂences.
The reÂsearchÂers had preÂviÂously found vinÂcloÂzolin exÂpoÂsure can efÂfect subÂseÂquent generaÂtÂions by afÂfectÂing how genes are turned on and off, a proÂcess called epiÂgeÂnetÂics. In that case, the epÂiÂgeÂnetÂic inÂherÂitÂance alÂtered how rats choose mates.
The new reÂsearch goes furÂther.
“How well you soÂcialÂize or how your anxÂiÂeÂty levÂels reÂspond to stress may be as much your anÂcesÂtral epÂiÂgeÂnetÂic inÂherÂitÂance as your inÂdiÂvidÂual early-life events,” SkinÂner said. This could exÂplain why some peoÂple sufÂfer post-traumatic stress synÂdrome while othÂers don”™t, he added.
“We have been seeÂing real inÂcreases in menÂtal disÂorÂders like auÂtism and biÂpoÂlar disÂorÂder,” said Crews. “It”™s more than just a change in diÂagÂnosÂtics. The quesÂtion is why? Is it beÂcause we are livÂing in a more frantic world, or beÂcause we are livÂing in a more frantic world and are reÂsponding to that in a difÂferÂent way beÂcause we have been exÂposed? I faÂvor the latÂter.”Leave a reply →
