New study says ADHD, autism may be due to fluoride, pesticides


A new study published in The Lancet has implicated six new chemicals that may be contributing to the development of childhood mental disorders, including attention deficit hyperactivity disorder (ADHD) and autism. The study follows on a study conducted by its authors in 2006 which identified "developmental nerutoxicants."

Researchers from the Harvard School of Public Health and Icahn School of Medicine at Mount Sinai added six new chemicals to a growing list of what they call "developmental neurotoxicants." This study adds manganese, fluoride, chlorpyrifos, and DDT to the list. The last two are pesticides and all on the list are chemicals often found in industrial use or waste.

The study was co-authored by adjunct professor of environmental health Philippe Grandjean of the Harvard School and Dr. Philip Landrigan, Dean for Global Health at Mount Sinai.

The new study can be found on the Lancet's website.
