Top Ten Toxic Chemicals Suspected to Cause Autism and Learning Disabilities

Philip Landrigan, MD, MSc, a leader in children’s environmental health and Director of the Children’s Environmental Health Center (CEHC) at Mount Sinai School of Medicine, co-authored the editorial, entitled “A Research Strategy to Discover the Environmental Causes of Autism and Neurodevelopmental Disabilities,” along with Luca Lambertini, PhD, MPH, MSc, Assistant Professor of Preventive Medicine at Mount Sinai and Linda Birnbaum, Director of the National Institute OF Environmental Health Sciences.

The editorial was published alongside four other papers — each suggesting a link between toxic chemicals and autism. Both the editorial and the papers originated at a conference hosted by CEHC in December 2010.

“A large number of the chemicals in widest use have not undergone even minimal assessment of potential toxicity and this is of great concern,” says Dr. Landrigan. “Knowledge of environmental causes of neurodevelopmental disorders is critically important because they are potentially preventable.”……

CEHC developed the list of ten chemicals found in consumer products that are suspected to contribute to autism and learning disabilities to guide a research strategy to discover potentially preventable environmental causes. The top ten chemicals are:

1. Lead

2. Methylmercury

3. PCBs

4. Organophosphate pesticides

5. Organochlorine pesticides

6. Endocrine disruptors

7. Automotive exhaust

8. Polycyclic aromatic hydrocarbons

9. Brominated flame retardants

10. Perfluorinated compounds

In addition to the editorial, the other four papers also call for increased research to identify the possible environmental causes of autism in America’s children. The first paper, written by a team at the University of Wisconsin — Milwaukee, found preliminary evidence linking smoking during pregnancy to Asperger’s disorder and other forms of high-functioning autism. Two papers, written by researchers at the University of California — Davis, show that PCBs disrupt early brain development. The final paper, also by a team at UC — Davis, suggests further exploring the link between pesticide exposure and autism.
