To examine fluoride, which is in tap water in many areas, Landrigan and Grandjean looked at an analysis of 27 studies of children, mostly in China, who were exposed to fluoride in drinking water at high concentrations. The data, they said, suggests a decline on average of about seven IQ points.

Since 2006, epidemiological studies have documented
six additional developmental neurotoxicants—manganese, fluoride, chlorpyrifos, dichlorodiphenyltrichloroethane, tetrachloroethylene, and the polybrominated diphenyl ethers. READ STUDY…LANCET JOURNAL

The two have been studying industrial chemicals for about 30 years. In 2006, they published data identifying five chemicals as neurotoxicants — substances that impact brain development and can cause a number of neurodevelopmental disabilities including attention-deficit hyperactivity disorder, autism, dyslexia and other cognitive damage, they said.

Those five are lead, methylmercury, arsenic, polychlorinated biphenyls, or PCBs, and toluene.

• Two scientists are sounding the alarm over chemicals and brain development
• They are calling for a worldwide overhaul of the regulatory process
• The American Chemical Council says the review is “highly flawed”
• The researchers say impacts could include ADHD and dyslexia   Read more…

Why ethyl mercury — the kind found in vaccines that the pro vaccine apologists say is safe — is actually many times more toxic than methyl mercury which pro vaccine apologists says is unsafe.

American Dental Association recommends using fluoride to poison infants as young as six months old.
