Harvard Professor: Fluoride Toxic to Children, Linked to Autism

| February 20, 2014 12:49 pm

Practically overnight, fluoride joined the likes of lead, arsenic, methylmercury, toluene and other chemicals known to damage brain tissue, reports the Fluoride Action Network (FAN).

In the March 2014 journal Lancet Neurology, the highly prevalent chemical was reclassified as a developmental neurotoxin by medical authorities.
The authors, Dr. Philippe Grandjean of the Harvard School of Public Health and Dr. Philip Landrigan of the Icahn School of Medicine write, “A meta-analysis of 27 cross-sectional studies of children exposed to fluoride in drinking water, mainly from China, suggests an average IQ decrement of about seven points in children exposed to raised fluoride concentrations.”

The majority of these 27 studies had water fluoride levels of less than four milligrams per liter, which falls under the allowable level set by the U.S. Environmental Protection Agency.
Developmental neurotoxins, which are capable of causing widespread brain disorders such as autism, attention deficit hyperactivity disorder, learning disabilities, often cause untreatable and permanent damage.
Grandjean and Landrigan write, “Our very great concern is that children worldwide are being exposed to unrecognized toxic chemicals that are silently eroding intelligence, disrupting behaviors, truncating future achievements and damaging societies, perhaps most seriously in developing countries.”

Strontium, PFOA and toxic chemicals found in one-third of U.S. water supply

(NaturalNews) You may want to think twice before further drinking or even bathing in unfiltered tap water, as a new report set to be published next year has found that a striking percentage of the U.S. water supply is contaminated with heavy metals, pesticides and other toxic chemicals. Researchers from the U.S. Geological Survey (USGS) and the U.S. Environmental Protection Agency (EPA) found that an astounding one-third of U.S. water systems contain traces of at least 18 unregulated and potentially hazardous contaminants, many of which are linked to causing endocrine disruption and cancer.

Based on a nationwide survey of 25 unnamed water utilities, scientists found traces of the herbicide metolachlor, for instance, a pesticide commonly applied to conventional corn, soy, cotton, safflower, potato and other crops, as well as the heavy metal strontium, which is linked to causing bone problems. Other chemicals identified include so-called perfluorinated compounds like perfluorooctanoic acid (PFOA), which numerous scientific studies have found can cause thyroid disease and various types of cancer.

"Traces of 18 unregulated chemicals were found in drinking water from more than one-third of U.S. water utilities in a nationwide sampling," reports Environmental Health News (EHN). "Included are 11 perfluorinated compounds, an herbicide, two solvents, caffeine, an antibacterial compound, a metal and an antidepressant."

More than 250 potential hazardous compounds detected in tap water

Among the 25 water samples, more than 250 chemicals, bacteria, viruses and microbes were identified, but only 134 of these were detected in treated drinking water. As many as eight of the treated water samples collected contained upwards of 113 chemicals. According to the researchers, water samples were taken from a range of water utilities, including both large and small plants and plants using varying treatment technologies.

"The good news is the concentrations are generally pretty low," stated Dana Kolpin, a research hydrologist from USGS who helped work on the study. "But there's still the unknown. Are there long-term consequences of low-level exposure to these chemicals?"
