Dry Cleaners Linked to Parkinson's Risk
22 Aug
Summary
- Living near dry cleaners increases Parkinson's disease risk.
- Trichloroethylene (TCE) is a chemical linked to the increased risk.
- Risk is more pronounced in specific regions of the U.S.
Researchers have found a notable association between residing near dry cleaning establishments and an increased risk of developing Parkinson's disease. Individuals living within 500 feet of a dry cleaner exhibited approximately 14% higher odds of developing the condition. This risk was particularly elevated for a type of Parkinson's that affects mobility and balance, with those nearby being 23% more likely to develop it.
The study points to chemicals like Trichloroethylene (TCE), a known carcinogen also used in dry cleaning, as potential contributors to this elevated risk. TCE and its related compound perchloroethylene (PCE) are of significant concern due to their neurotoxicity and environmental persistence. The research highlights a clear dose-response relationship, with the greatest risk observed in those living closest to a dry cleaner.
Certain regions within the United States showed a more pronounced risk. For instance, Southern Illinois saw a 150% higher risk for those near dry cleaners, while the Tennessee-Kentucky border region experienced a 110% increase. Central Pennsylvania's risk doubled, with other areas like North Central Indiana, Dallas-Fort Worth, Southern California, and the greater Detroit area also reporting higher odds. Researchers attribute this geographical variance to factors such as aging infrastructure, geology, or population density.
