Parkinson's linked to industrial cleaner

(Ivanhoe Newswire) -- Workers exposed to tricholorethylene (TCE), a chemical once widely used to clean metal such as auto parts, may be at significant risk of developing Parkinson's disease.
"This is the first time a population-based study has confirmed case reports that exposure to TCE may increase a person's risk of developing Parkinson's disease," study author Samuel Goldman, M.D., with the Parkinson's Institute in Sunnyvale, Calif., was quoted as saying. "TCE was once a popular industrial solvent used in dry cleaning and to clean grease off metal parts, but due to other health concerns the chemical is no longer widely used."
Researchers obtained job histories from 99 pairs of twins in which only one of the twins had Parkinson's disease. All of the twins were men and were identified from the World War II-Veterans Twins Cohort study. Scientists used twins in the study because they are genetically identical or very similar and provide an ideal population for evaluating environmental risk factors.
The study found workers who were exposed to TCE were five and a half times more likely to have Parkinson's disease than people not exposed to the chemical. Those who were exposed to TCE had job histories that included work as dry cleaners, machinists, mechanics or electricians.
