Babies Born Polluted: PFAS Levels Higher Than Thought
14 Mar
Summary
- Fetuses likely have far higher PFAS levels than previously assumed.
- Expanded testing found 42 PFAS compounds in umbilical cord blood.
- Chemical makers' new compounds may be less scrutinized, posing risks.
Recent peer-reviewed research suggests that fetuses are exposed to substantially higher levels of PFAS, commonly known as "forever chemicals," than previously detected. A Mount Sinai study analyzed 120 umbilical cord blood samples using an expanded 'non-targeted analysis.' This method identified 42 distinct PFAS compounds, revealing a total chemical presence far exceeding previous estimates based on testing for only a few common compounds like PFOA and PFOS.
These findings underscore a critical vulnerability period for developing fetuses. The chemicals, used in many consumer products for their water- and grease-resistant properties, have been linked to numerous health issues. "Legacy" compounds have been phased out, but newer generations of PFAS, which may also break down into harmful substances, are often not adequately tested for by regulators.
The study compared traditional analysis with the more comprehensive approach, demonstrating how current regulatory methods may underestimate the true extent of PFAS exposure. While the specific health impacts of this increased exposure were not examined, elevated PFAS levels are generally associated with heightened health risks. Experts emphasize the need for more robust regulations to protect infants from prenatal exposure to these persistent chemicals.
