Does Trichloroethylene Cause Parkinson's?
"I think people will really move on this as quickly as possible now" said Dr. Samuel Goldman of the Parkinson's Institute in Sunnyvale, CA according to the LATimes. Goldman was interviewed about a soon to be released study indicating that while other industrial solvents like xylene, toluene and n-hexane were not associated with Parkinson's, trichloroethylene (TCE) was strongly and significantly associated with the malady.
The results are to be presented in April at a meeting of the American Academy of Neurology and so there's not much to assess at the moment save the large grain of salt to be taken with any science that makes its way into the popular media before it lands in a journal. Nevertheless, the finding, if borne out by subsequent population studies, would be significant. Many substances have been blamed for Parkinson's but none with the 5.5 relative risk reported in this, well, press release.
