One study found evidence of dozens of man-made chemicals that were previously found in humans in the blood of pregnant women and their newborns.
Researchers at the University of California, San Francisco (UCSF) collected the blood of 30 pregnant women, along with samples of their umbilical cord, and analyzed it using high-resolution mass spectrometry (HRMS) to identify man-made chemicals in the blood.

Scientists discovered 109 chemicals during the study, 55 of which have never been reported in humans and 42 labeled “secret chemicals” without sources or known uses. The researchers said the chemicals mostly come from consumer products or other industrial sources and the fact that they are found in the blood of both pregnant women and their babies suggests that they travel from the mother’s placenta.
Tracy J., Professor of Obstetrics, Gynecology and Reproductive Sciences at UCSF. Woodruff said, “These chemicals may have been in people for a long time, but our technology is now helping us identify more of them.” Said.
People come into contact with containers as well as other products by eating, drinking and being exposed to man-made chemicals. The chemicals found are used to make plastics more profitable, pharmaceuticals, consumer products, pesticides and flame resistant. It also includes PFAS compounds, which have been used in various industries around the world and in the US since the 1940s.
“It’s worrying that we see some chemicals going from pregnant women to their babies, which means these chemicals could be with us for generations.”
The study was published in Environmental science and technology.
