Longitudinal study assesses PFAS levels in children, suggesting health implications at age 2.
• Longitudinal PFAS profiles were characterized from birth to age 7. • PFCAs and PFSAs increased by 6–32% per year across childhood. • 6:2Cl-PFESA, 8:2Cl-PFESA, and FOSA-I declined by 7–15% per year across childhood. • Breastfeeding, BMI, family context, and residence influenced PFAS burden. • Hazard assessment suggested a great immune concern at age 2.
