Textiles & Parkinson's Disease

Parkinson's disease is a degenerative condition marked by severe tremors and rigidity in the limbs. While genetics can make a person more vulnerable to this disease, environment also plays a role. Recent studies show that the industrial solvent trichloroethylene (TCE), a chemical once used in dry cleaning and textile processing, is linked to the development of Parkinson's.

Why is TCE a Risk?

• Parkinson's disease is caused by the death of brain cells that secrete dopamine. Animal studies have shown that TCE kills these cells. There have also been several reports of workers who have been exposed to TCE and later develop Parkinson's disease. Studies of identical and fraternal twins have confirmed the link between TCE and Parkinson's---twins who worked with TCE were much more likely to have developed Parkinson's than their brothers that were not exposed to the solvent.

Where is TCE found?

• TCE is used, or has been used in the past for degreasing metal parts, dry cleaning and processing textiles, and is also found in many household products such as paints, correction fluid, lacquers and spot removers. TCE is also sometimes found in water systems and ground water. The use of this solvent is being phased out due to awareness of the risks involved.

Who is at Risk?

• Those who are most at risk for TCE exposure include men who have worked as dry cleaners, machinists, mechanics or electricians.
