Pesticides and risk of Parkinson disease  (01.01.05)
Firestone JA, Smith-Weller T, Franklin G, Swanson P, Longstreth Jr. WT, and Checkoway H, Pesticides and risk of Parkinson disease: a population-based case-control study, Archives of Neurology 62(1), 91-95, 2005

A study in the US on factors influencing Parkinson’s disease reported relative risks of 1.41 and 1.67 (not statistically significant) for herbicide and paraquat exposure, respectively (Firestone et al 2005). Workers in these studies were exposed to different pesticides and this makes it more difficult to establish a significant association for individual pesticides.
