Ethylene oxide is a chemical used in hospital disinfectants.
More Than Just Hospitals
Ethylene oxide is also found in antifreeze, detergents, and some household products.
COVID Tests and Ethylene Oxide
Small amounts of ethylene oxide are present in the liquid used in some COVID-19 lateral flow tests.
The Scary Link: Ethylene Oxide and Newborns
Spanish research suggests exposure to ethylene oxide during pregnancy may lead to lower birth weight and smaller head circumference in newborns.
The Potential Consequences
Smaller head circumference has been linked to developmental delays, while low birth weight increases the risk of future health problems.
Smokers and Ethylene Oxide Exposure
The study found the highest levels of ethylene oxide in newborns born to mothers who smoked.
Beyond Smoking: Everyday Sources
Exposure can also occur through indoor air pollution from various household products and healthcare settings where ethylene oxide is used for sterilization.
The Need for Minimization
Researchers emphasize minimizing exposure to ethylene oxide for women of childbearing age, both at home and work. Policy changes to reduce exposure are crucial.
Existing Regulations and Reassurance
Official advice states trace amounts in medical devices like COVID tests are unlikely to harm unborn babies. Further research is needed to determine safe exposure levels.
