	maternal, 16 weeks [frequency of detection, %]	maternal, delivery [frequency of detection, %]	infant’s cord serum [frequency of detection, %]
Et-PFOSA-AcOH	<LOD [23.9]	<LOD [9.9]	<LOD [11.3]
Me-PFOSA-AcOH	0.50 [100]	0.20 [88.7]	0.30 [93.0]
PFOSA	<LOD [1.4]	<LOD [0]	<LOD [0]
PFHxS	1.20 [98.6]	1.20 [93.0]	0.60 [97.2]
PFOS	12.70 [100]	8.50 [100]	3.50 [98.6]
PFOA	4.80 [100]	3.30 [100]	3.10 [100]

PFDeA	0.20 [97.2]	0.20 [90.1]	<LOD [16.9]

The limits of detection (LODs) were 0.087 μg/L (Me-PFOSA-AcOH), 0.082 μg/L (PFNA), 0.1 μg/L (PFHxS, PFOA, PFDeA, PFOSA, Et-PFOSA-AcOH), and 0.2 μg/L (PFOS).
