Environmental Exposure to Iron, Manganese, and Pesticides: A possible cause of Parkinson's Disease Abstract Parkinson's disease has been linked to many environmental causes such as pesticides, iron, and manganese (Mn); Parkinson's disease (PD) affects millions of people across the United States. The causation of this disease could be linked to iron and manganese. Many studies look at exposure factors such as the chemical dieldrin. People who live in rural areas are more susceptible to the risk of PD; this could occur through the drinking of contaminated water or extensive exposure to pesticides. |
