Used across numerous industries and military applications, TCE is an industrial pollutant and solvent, known for its degreasing properties and utility in spot dry cleaning2. Although the usage of TCE has seen a decline, it remains deeply embedded in various industrial processes. The situation becomes direr when we consider the widespread contamination caused by TCE. It has permeated into half of the most toxic Superfund sites identified by the Environmental Protection Agency (EPA)2. Moreover, several military bases, including Camp Lejeune, bear the brunt of this contamination. The omnipresence of TCE necessitates a profound understanding of its impact on public health.
In an unsettling revelation that will prompt us to reconsider the choices we make daily, a growing body of scientific research has linked the widely used chemical, trichloroethylene (TCE), to Parkinson’s disease[1]. Parkinson’s, a degenerative disorder affecting the nervous system, has seen an alarming global upsurge. The connection between this neural condition and TCE, a chemical ubiquitously found in industries such as dry cleaning and metal degreasing, is, indeed, deeply worrying [2].
The Pervasive Threat: Trichloroethylene (TCE)
Used across numerous industries and military applications, TCE is an industrial pollutant and solvent, known for its degreasing properties and utility in spot dry cleaning [2]. Although the usage of TCE has seen a decline, it remains deeply embedded in various industrial processes. The situation becomes direr when we consider the widespread contamination caused by TCE.

Moreover, several military bases, including Camp Lejeune, bear the brunt of this contamination. The omnipresence of TCE necessitates a profound understanding of its impact on public health.
Exploring the Connection: TCE and Parkinson’s Disease
Researchers have suspected a potential association between TCE and Parkinson’s disease for quite some time, and recent studies have lent considerable credence to this claim1. Animal studies show that TCE can enter the brain and inflict significant damage on the mitochondria, the cells’ powerhouses1. High doses of TCE can cause a selective loss of dopamine-producing nerve cells, a distinctive feature of Parkinson’s disease in humans1.
The risk is not confined to occupational exposure. TCE can seep into our lives through outdoor and indoor air, along with contaminated groundwater1.
Case studies further illuminate the potential danger. The tale of former NBA player Brian Grant is particularly poignant. He was diagnosed with Parkinson’s at 36, having likely been exposed to TCE as a child when his father was stationed at Camp Lejeune1. Likewise, a Navy captain developed Parkinson’s disease 30 years after exposure to TCE-contaminated water at Camp Lejeune1. These stories underline the difficulty in establishing a direct causal link between TCE exposure and Parkinson’s disease as symptoms can manifest decades after exposure.
Protecting Public Health: Proactive Measures against TCE
The implications of TCE exposure demand urgent attention. Remediation of contaminated sites is a necessary first step1. Implementation of vapor remediation systems, akin to those used for radon, can help minimize indoor air exposure1.
Further research is required to comprehend how TCE contributes to Parkinson’s disease and other associated health complications1. Monitoring TCE levels in various environments, including groundwater, drinking water, soil, and indoor and outdoor air, is indispensable for public health protection1.
