Lead Linked to Autism - Fluoride Increases Lead Absorption

A new study reveals that children with Autism had much higher levels of lead levels throughout their development, according to Medical News Today.

The new research was led by Manish Arora, Ph.D., an environmental scientist and dentist at the Icahn School of Medicine at Mount Sinai in New York City, NY, and the findings were published in the journal Nature Communications.

Naturally exfoliated baby teeth were analyzed for lead content. However, fluoride level wasn't mentioned; but should be tested.

Lead is allowed in fluoridation chemicals used in most US public water supplies

Here's an explanation of how that occurs.

Also, while not providing a direct link to autism, several studies show that fluoride increases blood lead levels.  

Fluoride chemicals added to public water supplies, boosts lead absorption in lab animals' bones, teeth and blood, report Sawan, et al. (Toxicology 2/2010).
Earlier studies already show children's blood-lead-levels are higher in
 fluoridated communities, reports Sawan's research team.

"…exposure to increased amounts of lead and fluoride occurs at about the same age (1-3 years)… Therefore, this is a critical time when systemic exposure to fluoride should be minimized since fluoride may increase lead accumulation," the researchers caution.

"These findings suggest that a biological effect, not recognized so far, may underlie the epidemiological association between increased blood-lead levels in children and water fluoridation," concludes Sawan's research team.

"[O]ur findings may have serious implications for populations exposed to
increased amounts  of both lead and fluoride, particularly young children,"
the research team writes.

Masters and Coplan's landmark studies show higher blood-lead-levels in

children living in silico-fluoridated communities. (Neurotoxicology 2000, 2007). 

Macek's research shows children's higher blood-lead-levels are associated with water fluoridation when lead is already in the environment
(Environmental Health Perspectives, 2006).
