A common dry-cleaning solvent may pose a hidden threat to liver health, according to a new study highlighted by ScienceDaily. Researchers measured blood levels of tetrachloroethylene (PCE) in a sample of people and found that those with detectable amounts were three times more likely to show signs of significant liver scarring. The chemical is also present in some household products, broadening its potential exposure beyond industrial settings.
The study's authors describe PCE as an "overlooked threat" to the liver, pointing to a need for greater awareness among clinicians and the public. Because the research is based on observational data, it does not prove causation, but the strength of the association warrants further investigation.
Given that dry cleaning is widespread and PCE lingers in the environment, these findings could inform future screening or regulatory discussions. The researchers emphasize that even low-level exposure may matter, though they did not specify a threshold in the available summary. More studies will be needed to confirm the link and explore how PCE damages liver tissue.
