50+ New Chemical Substances Found in Pregnant Women and Babies
50+ New Chemical Substances Found in Pregnant Women and Babies. Journal of Environmental Science and Technology: Researchers have discovered more than 50 new chemical substances in pregnant women and babies.
Contemporary people are absorbing all kinds of environmental pollutants all the time. A recent study in the Journal of Environmental Science and Technology found hundreds of environmental chemicals in pregnant women and newborns, some of which can interfere with endocrine functions, and more than 50 have never been found in humans before.
According to Tracey Woodruff, a researcher from the Health and Environmental Research Center at the University of California, San Francisco, in this study, the researchers recruited 30 blood samples from pregnant women who received prenatal care at Zuckerberg San Francisco General Hospital and UCSF Mission Bay Medical Center, including their newborn babies. Umbilical cord blood sample.
The researchers analyzed the blood samples with a high-resolution mass spectrometer and found that there were 109 special chemical substances in these maternal and umbilical cord blood samples, 55 of which have never been found in the human body, and even 37 have never been discovered by the researchers. I have seen a chemical substance without any valid information.
The current methods for monitoring human exposure to chemical substances only involve the production or import of hundreds of approximately 8,000 chemical substances each year. For these newly discovered chemical substances in the human body, it is not yet clear that its potential impact on health. This is an alert to human health, indicating that everyone is being exposed to poorly understood chemicals. Whether they will be harmful or not is unpredictable.
Among the known chemicals, the most common are perfluoroalkyl and polyfluoroalkyl compounds. These chemicals are often used in consumer products such as non-stick pans and pizza boxes. They can gradually accumulate and stay in animals for a long time. It can cause abnormal development of animals, cause liver, kidney and immune diseases, and is also related to a variety of health problems in human epidemiological studies. There are also 10 plasticizers, such as the most common phthalates in fast food packaging. Other chemicals are very common in cosmetics and pesticides.
Since the above chemical substances were found in samples from mothers and newborns, it is proved that the fetus has been exposed in the womb, and more research is needed to confirm whether these chemical substances will appear in fetal tissues.
Woodruff said that the body’s ability to protect itself is worse during pregnancy, and the hundreds of chemical substances above are likely to affect the mother’s health. Especially for the fetus, it is likely to cause childhood and lifelong consequences. Current mass spectrometry studies can only prove the presence of these substances, but cannot quantify them and cannot determine their specific toxicity. In the future, researchers will also study the human toxicity properties of chemical substances, and then use the toxicity information to prevent adverse health consequences as early as possible.
Woodruff suggested that this research can also warn consumers to minimize exposure to chemicals harmful to reproductive health, clean with non-toxic products, and eat less plastic packaging and canned food.
