In a report out this workweek , scientists argue that a common industrial chemical substance is contributing to Parkinson ’s disease . The chemical substance is called trichloroethylene , or TCE . And while some country have recently banned its use , TCE remains widely present throughout the U.S.
TCE is a colourless constitutional solvent that ’s been in habit for a C in various industries . It ’s most often deploy as a degreasing agent in commercial-grade or manufacturing facility , but it ’s also used as an ingredient in common household cleansing product , refrigerant , and ironic - cleansing , and was even an anaesthetic agent up through the 1970s . People working in these industry are most at risk for exposure to TCE , as are people in surrounding communities , since the chemical can contaminate soil and groundwater .
Too much acute pic to TCE is thought to irritate the lungs and skin as well as cause giddiness and head ache . It ’s also take acarcinogen , with prolonged photograph jazz to call down the risk of kidney cancer and possibly other strain of Cancer . And for more than a tenner , some scientist have made the grammatical case for TCE being a drive of Parkinson ’s disease , a neurodegenerative disorderliness that steadily destroys people ’s ability to move independently and often have dementia . About 90,000 people in the U.S. are diagnose with Parkinson ’s each year , while a million Americans are think to be living with it , according to theParkinson ’s Foundation .

In a paperpublishedTuesday in the Journal of Parkinson ’s Disease , many of these scientists have salute the evidence to date punt this speculation .
In a 2008 case cogitation , for case , researchers working on a clinical tribulation for Parkinson ’s disease describe find patients with a shared retentive history of TCE exposure . Subsequent research has further supported this link , such as a2012 study of twinsthat found an increased danger in sib with likely vulnerability to TCE and other funny chemical ( twin studies are often used to untangle potential risk factors of a disease ) . Other studies inanimalshave indicated that TCE can harm the specific web of neuron implicate in Parkinson ’s .
The new paper also profiles seven patients whose Parkinson ’s might be unite to TCE , including former NBA instrumentalist Brian Grant , who was diagnosed at the age of 36 , and now - exit U.S. Senator Johnny Isakson , who died in 2021 . In these cases , the patients had a known history of living or working near site where TCE levels were likely gamy , such as the military stem Camp Lejeune . Throughout the fifties to 1980s , TCE and other chemical pollute the imbibing water at the base , almost certainlycausing added cases of cancer and other sickness , according to the Agency for Toxic Substances and Disease Registry , part of the Centers for Disease Control and Prevention .
“ Millions of Americans have worked with TCE , and tens of millions have been ( often unwittingly ) exposed to the chemical through the water they drink and the indoor air they breathe , ” author Ray Dorsey , a neurologist at the University of Rochester Medical Center , secern Gizmodo in an email . “ TCE is known to cause Cancer the Crab and may be fueling the rise of the humans ’s quickest - growing brain disease . ”
This link is still base on indirect and limited datum . And not everyone is in agreement about the strength of the grounds . In itsinvestigationof Camp Lejeune , the CDC ’s ATSDR observe that the grounds for TCE ’s use in induce Parkinson ’s currently meet the standard of equipoise and above , meaning that it ’s at least as likely to be on-key as not — one footmark below having sufficient evidence for a causal link . It ’s also possible that TCE exposure does n’t increase people ’s peril of Parkinson ’s evenly ; maybe element like our genetics make us more or less susceptible to the harm it can make .
More research is needed to confirm if and how TCE ( along with a related chemical called perchloroethylene , or PCE ) could be induce Parkinson ’s , Dorsey and his workfellow say . But in light of its known and possible dangers , the chemical substance should already be ostracize , they add . They also recommend that sites where TCE pollution is abundant should be take and that people living or working in these areas should be inform of the risks and protected from the chemical ( there are way toremoveit from drinking urine , for example ) .
Plenty others are starting to agree with the generator . New York and Minnesota haverecently bannedTCE from most industrial uses . And this January , the EPA reaffirm its past judgment on TCE anddeterminedthat it “ present an unreasonable peril of combat injury to human health ” in its current usage . So far , however , federal activeness on the chemical substance seems to be put away , but the agencyhas saidit ’s form on novel rules that would blackball its manipulation as a commercial degreaser and dry - cleansing ingredient .
