Experts stunned by link between everyday exposure and liver damage.
A new study has revealed a connection between a widely used chemical found in household cleaning products and a potentially fatal liver condition.
Researchers from the Keck School of Medicine at the University of Southern California found that exposure to tetrachloroethylene (PCE) may triple the risk of developing liver fibrosis, a condition that can lead to liver failure or cancer.
The study analyzed blood samples from 1,614 adults aged 20 and older between 2017 and 2020, collected through the National Health and Nutrition Examination Survey.
PCE is often found in adhesives, spot removers, and stainless steel cleaners.
While previous studies mainly focused on workers with direct contact, like those in dry cleaning facilities, this research shows that the general public may also be at risk.
Especially those who frequently use dry cleaning services.
What is liver fibrosis?
Liver fibrosis is the gradual buildup of scar tissue in the liver.
Over time, this scarring reduces blood flow and affects the liver’s ability to function properly.
According to the Cleveland Clinic, fibrosis can lead to liver failure, liver cancer, or even death.
But it can also be reversible if detected early.
Dr. Brian P. Lee, the study’s lead author and a liver specialist, said he was surprised by how widespread PCE exposure was among Americans.
“We were surprised that so many people have detectable PCE in their blood, and that the link with liver scarring was so strong,” Lee said, as cited by Unilad.
Wealthier households more at risk
The study also found that individuals from higher-income households had a greater chance of exposure.
This may be due to more frequent use of dry cleaning services, where PCE is commonly used.
Dr. Lee stressed that many people affected by PCE-related liver damage had no other known liver disease risk factors such as obesity or alcohol use.
“If a patient has liver fibrosis and no known cause, PCE exposure might be the missing piece,” he said.
