In addition to the NTP’s effort, NIEHS-funded
grantees across the country are researching PFCs.
For example, some are exploring a potential link
between PFCs and behavioral disorders, including
attention deficit hyperactivity disorder,9 while
others are evaluating the potential adverse health
risks of PFCs and other chemicals on
neurobehavioral development and immune function.For example, a 2012 NIEHS-funded
human study found that elevated PFC exposures
during development were associated with reduced
vaccine-induced immune protection in children.": https://www.atsdr.cdc.gov/sites/pease/documents/perflourinated_chemicals_508.pdf?utm_source=pocket_saves
"Why should this concern me so much? I thought having just binned a moderately expensive jacket to the waste (after approx. 5 years or so), because the synthetic lining had started to particulate and I was in danger of inspiring such (Teflon tasting muck). well truth's in the title, for such are "fluorinated" compounds and it was fluoride that ruined my life (and the effects of which nearly killed me on numerous occasions -in-fact the jury is still out on that one-), quote; "Fluoride treatments at the dentist's office are equally hazardous. In the typical fluoride treatment, 10,000 parts per million fluoride, which comes in a flavoured gel to make it taste good, is left on the teeth for about five minutes. Then the child spits it out, though invariable he swallows some. The child cannot rinse, eat or drink for at least half an hour afterward. Children have died after swallowing fluoride topically applied on their teeth. In one well publicized case, the dental hygienist neglected to tell the child to wash his mouth out and spit out the solution. The child began vomiting and sweating and died the same day*".."I am a victim of pre-pubescent dental clinical fluoride treatment myself (my story is sad, long and ongoing). These articles hint that there may be even higher costs to the patient/victim but don't make the connections (as "we" the victims don't anymore), however I can talk from my experience as-well and this has lead me to the conclusion that fluoride is a "whole system" disruptor and can be responsible for ailments as diverse as; fracturing, kidney failure/dysfunction, behavioural problems/brain damage, depression and suicide.
What I have not seen however (or been able to find so far on-line), are the statistics, the epidemiological evidence which will prove (I now have no doubt), that many of the "victims" of clinical fluoride treatment are no longer with us. For one thing the behavioural changes induced by fluoride treatment are of such an uncontrollable and self-destructive nature that the patient may perish due to some apparently "self-induced" accident superficially unrelated to any dental treatment they may have received a decade or so before. Therefore it is necessary to examine the medical records of all of those patients who received clinical fluoride treatment as children and compare the statistics for the incidences of accidental "premature" deaths (esp. "self-induced" -not necessarily suicide at all but the suicide statistics MUST be examined as-well-), and serious injuries within the treated group with those for the same demographic within the wider population."
