Study Finds Alarming Levels of ‘Forever Chemicals’ In US Mothers’ Breast Milk
Slashdot reader Hmmmmmm quotes the Guardian:

A new study that checked American women’s breast milk for PFAS contamination detected the toxic chemical in all 50 samples tested, and at levels nearly 2,000 times higher than the level some public health advocates advise is safe for drinking water. The findings “are cause for concern” and highlight a potential threat to newborns’ health, the study’s authors say. “The study shows that PFAS contamination of breast milk is likely universal in the US, and that these harmful chemicals are contaminating what should be nature’s perfect food,” said Erika Schreder, a co-author and science director with Toxic Free Future, a Seattle-based non-profit that pushes industry to find alternatives to the chemicals.

PFAS, or per and polyfluoroalkyl substances, are a class of about 9,000 compounds that are used to make products like food packaging, clothing and carpeting water and stain resistant. They are called “forever chemicals” because they do not naturally break down and have been found to accumulate in humans. They are linked to cancer, birth defects, liver disease, thyroid disease, plummeting sperm counts and a range of other serious health problems. The peer-reviewed study, published on Thursday in the Environmental Science and Technology journal, found PFAS at levels in milk ranging from 50 parts per trillion (ppt) to more than 1,850ppt.

There are no standards for PFAS in breast milk, but the public health advocacy organization Environmental Working Group puts its advisory target for drinking water at 1ppt, and the federal Agency for Toxic Substances and Disease Registry, within the Department of Health and Human Services, recommends as little as 14ppt in children’s drinking water.
