Why are Mechanics at Elevated Risk for Parkinson’s Disease?

Published on February 20th, 2023 by Andrew Hughes

Mechanics and other tradesmen are at an increased risk for Parkinson’s disease as a result of chronic occupational exposures to chlorinated solvents. Call 1 (800) 236-9363 to learn more.

Chlorinated Solvents & Parkinson's Disease

What are Chlorinated Solvents?

The term “chlorinated solvents” refers to a large family of solvents that contain chlorine. At room temperature, chlorinated solvents typically appear in the form of a sweet-smelling colorless liquid. Examples of common chlorinated solvents include:

  • Trichloroethylene (TCE)
  • Tetrachloroethylene (AKA Perchloroethylene, PERC, or PCE)
  • 1,1,1-trichloroethane (TCA)
  • Methylene Chloride (AKA Dichloromethane or DCM)
  • Vinyl Chloride (VC)

Are Chlorinated Solvents Toxic?

Chlorinated solvents can be very toxic. A high-concentration exposure to a chlorinated solvent can cause unconsciousness, coma, and even death. Chronic low-level exposures to chlorinated solvents may result in irreversible damage to the liver, kidneys, lungs, blood, and central nervous system. [1-5] Several chlorinated solvents have also been classified as known or probable carcinogens. [6]

Can Chlorinated Solvents Cause Parkinson’s Disease?

In recent years, the scientific community has increasingly linked Parkinson’s disease to chlorinated solvents. Chronic exposures to trichloroethylene (TCE) and tetrachloroethylene (PERC), in particular, are associated with the development of Parkinson’s disease. [1-2] Exposures to TCE and PERC have also been tied to other neurological disorders such as toxic encephalopathy. [7] If you or a loved one suffered chronic exposures to chlorinated solvents and have received a related diagnosis, you may be entitled to compensation.

How are Mechanics Exposed to Chlorinated Solvents?

Chlorinated solvents can be found in many of the products which are marketed as solvents, degreasers, cleaners, sealants, lubricants, penetrating oils, paint thinners, paint strippers, and primers. Mechanics, electricians, machinists, pipefitters, painters, and other tradesmen are exposed to chlorinated solvents when using these products.

How do Dangerous Exposures Occur?

A dangerous exposure to a chlorinated solvent can occur by inhaling solvent vapors, by ingesting food or drink that has been contaminated with a chlorinated solvent, or by absorption through the skin. [1-5] Inhalation is often the primary pathway of occupational exposures, especially when working with chlorinated solvents sold in aerosol cans. Such exposures can be made much worse when working in cramped inspection pits or unventilated garages.

We May be Able to Help

Parkinson’s disease tends to develop later in life. Consequently, any contributing toxic exposures may have occurred decades ago. Linking these exposures to your illness will require experienced toxic tort attorneys. At Hughes Law Offices, working alongside our industrial hygiene and occupational medicine experts, we will take all of these exposures into account when building your case. Call 1 (800) 236-9363 for a free attorney consultation today. Your time to file a claim is limited.
