Children who were exposed to some PFAS chemicals in the womb displayed behavioral and emotional concerns by age 12, according to a new study published in Environmental Health Perspectives.
In short:
- Prenatal exposure to some types of PFAS was associated with an increase in hyperactivity, anxiety and depression later in childhood.
- The study measured PFAS levels in umbilical cord blood, highlighting the chemicals’ ability to cross into the placenta and impact the fetus.
- These findings were consistent for both boys and girls.
Key quote:
“Exposure during pregnancy represents a specific window of vulnerability for child health.”
Why this matters:
PFAS have been used in everyday consumer products for nearly a century. Some regulations, like the Stockholm convention’s list of banned chemicals, have been successful in reducing exposure to certain types of PFAS. However, levels of newer versions of PFAS (including the ones linked to health concerns in this study) are increasing worldwide, making it essential that chemical bans are strengthened and updated to provide comprehensive protection.
