Exposure to the industrial solvent trichloroethylene (TCE) and other volatile organic compounds in drinking water raised the risk of Parkinson’s disease decades later, an analysis of 158,000 military veterans showed.
Former Camp Lejeune residents also had a higher prevalence of prodromal features like tremor, suggesting that for some veterans, Parkinson’s might not yet be diagnosed.
Trichloroethylene has been used since the 1920s to de-grease metal, decaffeinate coffee, and dry clean clothes. It has been linked with cancer, miscarriages, neural tube defects, congenital heart disease, autoimmune disorders, and Parkinson’s disease in earlier research.
