Are Pesticides Causing Parkinson's Disease?

"Despite remaining uncertainties and data gaps," wrote the authors of the 2008 report by the Science and Environmental Health Network -- Jill Stein, Ted Schettler, Ben Rohrer, and Maria Valenti -- "the body of evidence linking pesticide exposure to Parkinson's disease fulfills generally accepted criteria for establishing causation." When combined with "extensive laboratory animal data" specifying the underlying biology of this relationship, they wrote, "collectively, this evidence supports the conclusion that pesticide exposures can cause Parkinson's disease in some people."
