Researchers studying twins found that exposure to the industrial solvent trichloroethylene (TCE), a hazardous organic contaminant used as a degreaser, is linked to a significant increase in the risk of developing Parkinson’s disease. Led by Drs Samuel Goldman and Caroline M. Tanner, of The Parkinson’s Institute (PI) and Clinical Center in Sunnyvale, California, the international team write about their findings in the 14 November online issue of Annals of Neurology.
The team also found links between raised Parkinson’s risk and exposure to perchloroethylene (PERC, also known as tetrachloroethylene), a leading solvent used in dry-cleaning, and carbon tetrachloride (CCl4), formerly used in fire extinguishers, as a cleaning agent, and in making refrigerants.
TCE is used in industry to degrease metals and other materials, and PERC is the leading solvent used in the dry-cleaning industry and in degreasers and spot removers. As well as the exposure that occurs from working with these chemicals, you can also be exposed through using the dozens of household products like glues, carpet cleaners, spot removers and paints that contain them.
