Scientists at University of California San Francisco have detected 109 chemicals in a study of pregnant women, including 55 chemicals never before reported in people and 42 “mystery chemicals,” whose sources and uses are unknown.
The chemicals most likely come from consumer products or other industrial sources. They were found both in the blood of pregnant women, as well as their newborn children, suggesting they are traveling through the mother’s placenta.
The study was published on March 16, 2021, in Environmental Science & Technology.
“These chemicals have probably been in people for quite some time, but our technology is now helping us to identify more of them,” said Tracey J. Woodruff, PhD, a professor of obstetrics, gynecology and reproductive sciences at UCSF.
A former U.S. Environmental Protection Agency scientist, Woodruff directs the Program on Reproductive Health and the Environment (PRHE) and the Environmental Research and Translation for Health (EaRTH) Center, both at UCSF.
“It is alarming that we keep seeing certain chemicals travel from pregnant women to their children, which means these chemicals can be with us for generations,” she said.
