Pollutants in some urban areas increase Parkinson’s disease risk
High levels of manganese and copper pollution in urban areas are linked to increased risk of Parkinson’s disease, according to a large-scale analysis of urban pollution and Parkinson’s incidence in the United States. Scientists at Washington University School of Medicine in St. Louis found that people living in areas with higher levels of manganese pollution had a 78 percent greater risk of Parkinson’s disease than those living in areas free of such pollution.
