Most of us don’t give a second thought to the bottles tucked away under the kitchen sink or the solvents used at the local dry cleaners.
We trust that if something has been a staple of industry for decades, it’s been vetted and cleared for regular use. However, a recent study has pointed a finger at a specific chemical called trichloroethylene, or TCE, suggesting a link to health problems we’re only just beginning to grasp.
It’s been used for everything from degreasing engines to cleaning carpets, but researchers are now finding that exposure to this common substance could be doing far more damage to our brains than previously thought. Before you brush it off as another health scare, you’ll want to see why experts are so concerned about the connection between TCE and the rising numbers of Parkinson’s cases.
Where this chemical has been used over the years
TCE has been widely used in factories, workshops, and cleaning processes where strong chemicals are needed to remove grease or dirt. In the past, it also showed up in products like spot cleaners and certain household items, although that’s less common now. Even though its use has been reduced, it hasn’t disappeared. In some places, it’s still used in industry, and in others, it lingers in the environment from years of past use, especially in soil and groundwater.
Why are scientists only just studying it now?
Researchers have started linking long-term exposure to TCE with a much higher risk of developing Parkinson’s disease. Some estimates suggest the risk could be up to 500% higher for people who have been exposed regularly over time. Obviously, not everyone who’s exposed will develop the condition, but it does suggest the chemical may play a bigger role than previously thought, especially for people who have come into contact with it over long periods.
How are people actually exposed to it?
Most people aren’t directly handling this chemical in everyday life, but exposure can still happen in less obvious ways. It can enter drinking water if it’s leaked into the ground, and it can also release vapours that build up in enclosed spaces. People who have worked in certain industries are more likely to have had higher exposure, but it’s also possible for communities near contaminated areas to come into contact with it without realising.
Most people would never even know TCE was in a product.
One of the biggest challenges with TCE is that you can’t easily see or smell it in many cases. It doesn’t always stand out, which means people can be exposed without knowing it’s there. Because of that, it’s not something that’s been widely discussed outside of scientific and environmental circles, even though it’s been in use for a long time.
What this means for everyday life

However, it does highlight how certain chemicals can stay in the background for years and still have long-term effects that only become clear later on.
A bit of awareness can go a long way.

It also raises questions about environmental safety, particularly in areas where old industrial activity may have left behind contamination that hasn’t fully been dealt with.
The risks are being taken much more seriously now.
There’s been a growing focus on how long-term, low-level exposure to certain substances can affect health over time. Instead of looking at immediate effects, researchers are now connecting the dots between past exposure and conditions that develop years later. That change in thinking is what’s bringing chemicals like TCE back into the spotlight, even though they’ve been around for decades.
