A chemical commonly used in dry cleaning and some consumer products may contribute to liver scarring and increase the risk of cirrhosis, researchers reported.
A research team from the University of Southern California explained that exposure to tetrachlorethylene may double the risk of developing dangerous cirrhosis, which is excessive scarring of liver tissue that may lead to cancer, organ failure, or death.
According to the Health Day website, the results of the study showed that the risk of infection increases as levels of exposure to this substance increase.
Tetrachloroethylene is widely used in dry cleaning of clothes, and is also used in some arts and crafts adhesives, spot cleaners, and stainless steel polishes.
Lead researcher Dr Brian Lee said: “This study, the first to investigate the relationship between PCE levels in humans and risky liver fibrosis, highlights the underreported role of environmental factors in liver health.”
Researchers have shown that exposure to this substance often occurs from inhaling polluted air, such as fumes emitted from dry-cleaned clothes, and it can also be transmitted through drinking water in areas affected by environmental pollution.
Due to its toxicity, the US Environmental Protection Agency launched a program to phase out its use in dry cleaning for 10 years.
